FIG. 1 is a schematic diagram of an embodiment of a camera device communicating with a sensing device, and FIG. 2 is a schematic diagram of a camera device module of an embodiment.

A camera device 100 includes: a communication module 110 , a processing module 120 and an adjustment module 130 . The camera device 100 is a camera device capable of recording images, videos and sounds, and is used for monitoring in the present invention. The camera device 100 is generally composed of two major physical parts: a camera and a pan/tilt. The camera is set on the cloud platform and is in a state of being able to rotate up, down, left, and right. It can be rotated left and right by controlling the motor horizontally, and rotated up and down by controlling the motor vertically.

Usually the camera will be set at an initial position as the standard position of the camera. When the camera needs to rotate to a certain direction, it is based on this standard position as the calculation base point. For example, when the camera is just at the standard position, and the camera needs to turn to a certain direction, it needs to be turned downward by an angle of α1 and rightward by an angle of β1; , Turning to the right by an angle of β2, the required rotation angle of the camera can be obtained as a downward angle of α2-α1, and a rightward rotation of an angle of β2-β1, and - is a minus sign.

The communication module 110 is used for receiving the first trigger information sent by the sensing device 200 to accept the monitoring task; the first trigger information includes the identification of the sensing device 200 .

The processing module 120 is configured to determine first direction information corresponding to the identification of the sensing device 200 according to the identification of the sensing device 200 .

The adjustment module 130 is used to adjust the rotation angle of the pan/tilt of the camera device 100 according to the first direction information, so that the camera installed on it faces the first direction corresponding to the first direction information to implement the recording in the first direction .

FIG. 3 is a flow chart of a method for controlling direction change tracking of a camera device according to an embodiment, please refer to FIG. 1 and FIG. 2 .

A camera device commutation tracking control method, comprising the steps of:

Step S110: the communication module 110 of the camera apparatus 100 receives the first trigger information sent by the sensing device 200 being triggered to accept the monitoring task. The first trigger information includes the identification of the sensing device 200 , for example, may be a physical address or a unique identifier of the sensing device 200 . The first trigger information has a corresponding monitoring task.

After being triggered, the sensing device 200 can send a trigger signal or information, which is equivalent to having the function of a trigger switch. The sensing device 200 may be a device that generates first trigger information when triggered by an external force. For example, in the present invention, the sensing device 200 may be a door sensor (Doorsensor).

The door sensor is used to detect whether doors, windows, drawers, etc. are illegally opened or moved. The so-called door magnet is actually a door magnetic switch, which basically consists of two parts: a permanent magnet and a door magnet body. There is a permanent magnet inside the permanent magnet, which is used to generate a constant magnetic field; there is a normally open reed switch inside the main body of the door magnet, and a wireless transmitter is connected; when the permanent magnet and the reed switch are close together (such as less than 5 mm), the door magnetic switch is in the working standby state; when the permanent magnet is away from the reed switch for a certain distance, the door magnetic switch is in the normally open state. Therefore, when the door sensor is installed on a door, window, drawer, etc., the door sensor can recognize it as an opening event when the door, window, drawer, etc. are opened or moved, and send the first trigger signal through the wireless transmitter; Of course, when objects such as doors, windows, and drawers are closed, the door sensor recognizes it as a closing event, and a second trigger signal can also be sent through the wireless transmitter.

The receiving host of the door sensor receives the first trigger signal or the second trigger signal, and converts the first trigger signal into the above-mentioned first trigger information, and converts the second trigger signal into the above-mentioned second trigger information, and then through wireless communication (such as Bluetooth communication) to send the first trigger information or the second trigger information to the imaging device 100 . Of course, the first trigger signal or the second trigger signal may also be directly sent to the imaging device 100 as the first trigger information or the second trigger information through the aforementioned wireless transmitter.

In some embodiments, the sensing device 200 may include a sensor device, such as a smoke sensor, a vibration sensor, an infrared sensor, and the like. Smoke sensors can be used to monitor smoke to monitor possible fire events, shock sensors can be used to monitor vibrations to monitor possible illegal damage or illegal entry events, infrared sensors can be used to monitor people's walking in and out events, when these sensors monitor When these events are detected, sensing signals will be generated, and the sensing signals will be sent as or converted into the first trigger information.

In the following description, the induction device 200 is used as the door sensor for the main description.

The communication module 110 of the imaging device 100 and the sensing device 200 may be connected through Bluetooth communication, and the sensing device 200 sends the first trigger information to the imaging device 100 through a pre-established Bluetooth trusted communication interface.

The pre-established Bluetooth trusted communication interface can be understood as a communication interface formed by the communication module 110 of the camera device 100 having performed Bluetooth pairing with the sensing device 200 in advance. For example, the camera device 100 and the sensing device 200 are pre-paired via Bluetooth before leaving the factory, or the camera device 100 and the sensing device 200 are paired by Bluetooth after they are in the hands of the user. The camera device 100 and the sensor device 200 that have been paired once via Bluetooth are equivalent to pre-establishing a Bluetooth trusted communication interface, so that the camera device 100 and the sensor device 200 can directly establish a trusted connection when they make a Bluetooth connection next time without Bluetooth pairing.

Therefore, in the first trigger information, usually also include the characteristic information or identification of the unique identification of the sensing device 200, such as at least one of the physical address (MAC) and the identifier (ID), so that the camera 100 can You can add it to the trust list, and it can be recognized and automatically established the next time you connect.

In order to minimize power consumption, Bluetooth Low Energy (BLE) is used between the communication module 110 of the camera device 100 and the sensing device 200 . BLE technology uses a variable connection time interval, which can be set from a few milliseconds to a few seconds depending on the specific application. In addition, because BLE technology uses a very fast connection method, it can be in a "non-connected" state (Standby, standby state) to reduce energy consumption. At this time, the two ends of the link only know each other, and the link is only opened when necessary. path, and then shut down the link in the shortest possible time.

The first trigger information and the second trigger information may be broadcast information in BLE technology. In the broadcast information, a trigger event code may also be included to distinguish the first trigger information from the second trigger information. The first trigger information is the trigger information generated by the door sensor opening, and the second trigger information is the trigger information generated by the door sensor closing, so the first trigger information can include the code (for example, 1) of the opening event, and the second trigger information Can include a code (eg 0) to close the event. After sending the broadcast information, the camera device 100 may switch from the broadcast state to the standby state, so as to save energy consumption.

In some cases, monitoring may not be required even if the door contact is triggered. For example, when the door sensor is installed on the door, window, or safe, when the door, window, or safe is opened and the door sensor is triggered, if it is a legal event performed by authorized personnel, no monitoring is required. Therefore, if the camera device 100 detects that the door sensor is triggered under a legal event, it can ignore the monitoring task after receiving the first trigger information of this trigger; Only after receiving the first trigger information of this trigger, the monitoring task will be accepted.

Therefore, it can be considered to combine the camera device with the door lock security system. When the door magnetism is installed on the door (gate, window door or safe door, etc.), if the door lock security system detects an illegal unlocking event and sends a dangerous message, the camera device 100 receives the dangerous message, and then receives the signal and is triggered by the sensing device 200. The first trigger information sent is to accept the monitoring task; the danger information is sent when the door lock safety system detects an illegal unlocking event. If the door lock security system detects a legal unlocking event and sends danger information, after receiving the security information, the camera device 100 receives the first trigger information sent by the sensing device being triggered and ignores the monitoring task; the security information is detected by the door lock security system Sent when a unlock event is legal. Certainly, in some embodiments, safety information may not be required, and the camera device 100 accepts monitoring tasks in response to the first trigger information only when receiving dangerous information, and does not accept monitoring in response to the first trigger information when no dangerous information is received. Task.

The door lock security system is a system that monitors whether the door lock is opened legally. When the door lock is opened illegally (such as violently unlocking), it will trigger the sending of the above-mentioned dangerous information; when the door lock is legally opened (such as entering a legal unlock password or When the correct key is used), the sending of the above-mentioned security message will be triggered. For example, a door lock security system may include an access control system.

In some cases, there may be more authorized personnel to perform legal events to trigger the door contact during a certain period of time. For example, during a party, a large number of partygoers may open the door to trigger the door contact. In an event period, the camera device 100 does not need to respond to the first trigger information to accept the monitoring task, and the camera device 100 does not respond to the first trigger message even if it receives the first trigger message sent by the sensing device 200 within the set time period. A trigger message to accept monitoring tasks.

Or in some cases, there are family members at home during the daytime. At this time, the camera device 100 is not required to closely monitor the gate. It is only necessary for the camera device 100 to closely monitor the gate at night for safety considerations. Therefore, the camera device 100 can be used at night The first trigger information sent by the sensing device 200 after being triggered is received within a set time period to accept the monitoring task.

The communication module 110 of the camera device 100 receives the first trigger information, accepts a corresponding monitoring task according to the content of the first trigger information, and then executes step S120.

Step S120: The processing module 120 of the camera device 100 determines the first direction information corresponding to the identification of the sensing device 200 according to the identification of the sensing device 200 . The first direction information is pre-stored in the storage medium of the camera device 100 , and the first direction information corresponds to the identification of the sensing device 200 .

The first direction in the first direction information is a certain direction for the imaging device 100 , and in most cases, it is the direction where the sensing device 200 is installed. The sensing device 200 is a door sensor installed on a door, window, safe, etc., and the first direction is the direction of the door, window, safe, etc. for the camera device 100 . Therefore, after the camera device 100 obtains the first direction information, it can know to turn the camera to the first direction to monitor the door, window, safe and other positions in the first direction.

Of course, the first direction may not be the direction where the sensing device 200 is located. For example, when the sensing device 200 is installed on a gate, the first direction may be a direction in which the camera 100 faces a passage coming in from the gate. In short, the first direction in the first direction information is the position direction that the user thinks most needs to be monitored after the sensing device 200 is triggered, and it is not necessarily the direction where the sensing device 200 is located. The same holds true when the sensing device 200 is a sensor device. For example, when the sensing device 200 is a smoke sensor, since the smoke sensor is usually installed on the ceiling, when the smoke sensor detects smoke, it is likely to send a fire event, so the camera device 100 needs to aim the camera at some fire-prone positions.

In some embodiments, the first direction information includes horizontal angle information and vertical angle information. Horizontal angle information and vertical angle information are relative to the standard position of the camera. For example, the vertical angle information is a downward rotation angle of α1, and the horizontal angle information is a rightward rotation angle of β1, and both α1 and β1 are relative to the standard position. As mentioned above, when the vertical angle information is α1 angle downward and the horizontal angle information is β1 angle rightward rotation, if the camera is not in the standard position, for example, the camera is in the downward rotation α2 angle relative to the standard position 1. Rotate the position of the angle β2 to the right, then the required rotation angle of the camera can be obtained as the angle α2-α1 downward, and the angle β2-β1 to the right.

Certainly, the first direction information may also be the information of the required rotation steps of the camera, such as the information of the horizontal rotation steps and the vertical rotation steps information. Similarly, the horizontal movement step information and the vertical movement step information are relative to the standard position of the camera. For example, the information on the number of vertical movement steps is X1 steps downward, and the information on the number of horizontal movement steps is Y1 steps to the right. Both X1 steps and Y1 steps are relative to the standard position. When the information on the number of vertical movement steps is X1 steps downward and the information on the number of horizontal movement steps is Y1 steps to the right, if the camera is not at the standard position, for example, the camera is at X2 steps downward relative to the standard position, Move the position of Y2 steps to the right, and the number of steps required to rotate the camera can be obtained as X2-X1 steps for downward movement and Y2-Y1 steps for rightward movement.

Multiple sensing devices 200 may correspond to different direction information according to their respective identifiers (such as MAC or ID). For example, the sensing device 200 may be installed on multiple gates, multiple windows, multiple safes, multiple sensors, etc. These sensing devices 200 are usually scattered and arranged in different locations, so the identification of the sensing device 200 can make the camera 100 The direction corresponding to each sensing device 200 is identified.

However, when there are multiple sensing devices 200, if there are multiple sensing devices 200 simultaneously receiving the trigger event and sending the first trigger information, since the respective first trigger information corresponds to their respective monitoring tasks, the imaging device 100 It may not be possible to determine the direction corresponding to which sensing device 200 is monitored, resulting in monitoring confusion. Therefore, it may be considered to set a corresponding priority level for each sensing device 200 , and when multiple sensing devices 200 receive trigger events and send first trigger information at the same time, monitor according to the direction corresponding to the sensing device 200 with the highest priority level. Therefore, the processing module 120 of the camera apparatus 100 may also determine priority level information corresponding to the identification of the sensing device 200 according to the identification of the sensing device 200 . Like the first direction information, the priority level information is also pre-stored in the storage medium of the imaging device 100 , and the priority level information corresponds to the identification of the sensing device 200 .

After the imaging device 100 obtains the first direction information, step S130 is performed.

Step S130: The adjustment module 130 of the camera device 100 adjusts the rotation angle of the pan/tilt of the camera device 100 according to the first direction information, so that the camera installed on it faces the first direction corresponding to the first direction information to implement the first direction information. Recording in one direction.

The adjustment module 130 of the camera device 100 can adjust the vertical rotation angle of the pan/tilt of the camera device 100 according to the vertical angle information and the current vertical angle, and can adjust the vertical rotation angle of the pan/tilt of the camera device 100 through a vertical control motor. Continuing to take the above description as an example, the vertical angle information is downward rotation α1 angle, and the current vertical angle is downward rotation α2 angle, then the gimbal vertical rotation angle α2-α1 can be adjusted. Of course, the adjustment module 130 of the camera device 100 can adjust the vertical rotation steps of the pan/tilt of the camera device 100 according to the information of the vertical motion steps and the current position, which will not be repeated here.

The adjustment module 130 of the camera device 100 can adjust the horizontal rotation angle of the pan/tilt of the camera device 100 according to the horizontal angle information and the current horizontal angle, and can adjust the horizontal rotation angle of the pan/tilt of the camera device 100 through a horizontal control motor. Continuing to take the above description as an example, if the horizontal angle information is β1 angle to the right, and the current horizontal angle is β2 angle to the right, then the gimbal can be adjusted to the angle of β2-β1 horizontal rotation. Certainly, the adjustment module 130 of the camera device 100 can adjust the number of horizontal rotation steps of the pan/tilt of the camera device 100 according to the horizontal motion step information and the current position, and details will not be repeated here.

According to the foregoing description, it can be known that the processing module 120 of the camera apparatus 100 may also determine the priority level information corresponding to the identification of the sensing device 200 according to the identification of the sensing device 200 . Therefore, the camera device 100 also needs to determine the monitoring task and adjust the orientation of the camera according to the priority level information.

The camera device 100 acquires the priority level information, and when the priority level information satisfies the setting conditions, it adjusts the rotation angle of the pan/tilt of the camera device 100 according to the first direction information, so that the orientation of the camera installed thereon is consistent with the first direction information. The corresponding first direction is used to implement the recording of the first direction. The setting conditions may include: the sensing device 200 has the highest priority or a higher priority than the sensing device corresponding to the previous monitoring task.

The following situations may exist:

1. The imaging device 100 acquires the first trigger information to accept the current monitoring task, determines that the priority level information is higher than the priority level of the sensing device corresponding to the previous monitoring task according to the identification of the sensing device 200, and then executes the current monitoring task;

2. The camera device 100 acquires the first trigger information to accept the current monitoring task, and determines the priority level information according to the identification of the sensing device 200 to be the same as the priority level of the sensing device corresponding to the previous monitoring task, then ignores the current monitoring task and continues to perform the previous monitoring task Task;

3. The camera device 100 acquires the first trigger information to accept the current monitoring task, and determines the priority level information according to the identification of the sensing device 200 is lower than the priority level of the sensing device corresponding to the previous monitoring task, then ignores the current monitoring task and continues to perform the previous monitoring task Task.

In some embodiments, the sensing device 200 may have the function of sending the second trigger information. The second trigger information is relative to the first trigger information. If the first trigger information is used to prompt the camera device 100 to implement monitoring, then The second trigger information is used to prompt the camera device 100 to cancel monitoring. For example, when the sensing device 200 is a door sensor, the first trigger information is the opening information representing an opening event (such as opening a door, opening a window, etc.), and the second trigger information is the information representing a closing event (such as opening a door, opening a window, etc.) Close message. Take the door sensor installed on the gate as an example. When the door is closed, the door sensor recognizes that the door is closed and triggers to send out the second trigger information. At this time, the camera device 100 has already known the opening and closing of the door and the situation of the people entering and leaving. monitoring, so the camera device 100 can cancel the current monitoring after receiving the second trigger information.

Therefore, after receiving the second trigger information sent by the sensing device 200 when the camera 100 is shooting, the processing module 120 cancels the current monitoring task. Likewise, the second trigger information includes characteristic information or identification unique to the sensing device 200 , such as at least one of a physical address (MAC) and an identifier (ID).

After the processing module 120 of the camera device 100 cancels the current monitoring task, the camera device 100 can continue the previous monitoring task, and the adjustment module 130 adjusts the rotation angle of the pan/tilt of the camera device 100 so that the orientation of the camera installed thereon is the same as that of the previous monitoring task. The direction corresponding to the monitoring task is implemented to record the direction. Alternatively, after the processing module 120 of the camera device 100 cancels the current monitoring task, the camera device 100 may continue to monitor at the current location until a new monitoring task is accepted.

When the processing module 120 of the camera device 100 cancels the current monitoring task, it may cancel the current monitoring task immediately, or cancel the current monitoring task after a preset period of time. Continuing to take the example of the gate above as an example, when the gate is closed, continue to monitor for a preset period of time (for example, 20 seconds), so as to avoid that the camera may frequently rotate if the gate is opened and closed one after another. Within this preset time period, if a new monitoring task is sent, the current monitoring task can be canceled immediately according to the new monitoring task.

After step S130, the transmission module of the camera device 100 can transmit the obtained recording information to a preset terminal or server. For example, when the door or window is opened or subjected to abnormal vibration, the camera device 100 can transmit the obtained recording information to a preset terminal in real time, such as a mobile terminal of the user in real time, so that the user can know the situation in the monitored home in real time. Alternatively, when the safe is opened illegally or vibrated abnormally, the camera device 100 can transmit the obtained recording information to the server of the police department, so that the police can know the emergency situation in time. The transmission module of the camera device 100 can communicate with a preset terminal or server through the Internet.

The camera 100 described above and its reversing tracking control method, the camera 100 receives the first trigger information sent by the sensing device 200 to accept the monitoring task; the first trigger information includes the identification of the sensing device 200; the camera 100 according to the sensing The identification of the device 200 determines the first direction information corresponding to the identification of the sensing device 200; adjusts the rotation angle of the pan/tilt of the camera device 100 according to the first direction information so that the orientation of the camera set on it is consistent with the first direction information The corresponding first direction is used to implement the recording of the first direction. The sensing device 200 may be a device that generates trigger information when triggered by an external force, such as a device with a switch trigger function such as a door sensor. The sensing device 200 is placed on important objects such as doors, windows, safes, etc. When these objects are triggered by opening or closing, the sensing device 200 can generate corresponding trigger information and send it to the camera 100, and the camera 100 can switch according to the trigger information. The direction to the object is purposefully monitored. In most cases, these important objects are not triggered at the same time, so a small number of cameras or even one camera can monitor multiple important objects or locations, greatly reducing construction costs and maintenance costs.

In the above description, the identification of the sensing device 200 corresponds to its first direction information and priority level information. The following describes a method for pairing a camera with a sensing device, which can establish the identification of the sensing device 200 and the first direction information and the mapping relationship between the identification of the sensing device 200 and the priority level information, so that the identification of the sensing device 200 corresponds to the respective first direction information and priority level information.

FIG. 4 is a flowchart of a pairing method between a camera device and a sensing device according to an embodiment, please combine FIG. 1 and FIG. 2 .

A method for pairing a camera device with a sensing device, comprising the steps of:

Step S210 : the communication module 110 of the camera device 100 obtains the identification of the sensing device 200 .

After being triggered, the sensing device 200 can send a trigger signal or information, which is equivalent to having the function of a trigger switch. The sensing device 200 may be a device that generates first trigger information when triggered by an external force. For example, in the present invention, the sensing device 200 may be a door sensor (Doorsensor).

In some embodiments, the sensing device 200 may include a sensor device, such as a smoke sensor, a vibration sensor, an infrared sensor, and the like. Smoke sensors can be used to monitor smoke to monitor possible fire events, shock sensors can be used to monitor vibrations to monitor possible illegal damage or illegal entry events, infrared sensors can be used to monitor people's walking in and out events, when these sensors monitor When these events are detected, sensing signals will be generated, and the sensing signals will be sent as or converted into the first trigger information.

The sensing device 200 may be printed with a barcode or a two-dimensional code, and the identification of the sensing device 200 may be obtained by scanning the barcode or two-dimensional code. When the camera device 100 has the function of scanning barcodes or two-dimensional codes, the camera device 100 can acquire the identification of the sensing device 200 by scanning the barcodes or two-dimensional codes. Alternatively, another smart mobile terminal can scan the barcode or two-dimensional code, and the smart mobile terminal can obtain the identification of the sensing device 200 and then send it to the camera 100, so that the camera 100 can indirectly obtain the identification of the sensing device 200. Of course, the camera 100 may obtain the identification of the sensing device 200 through Bluetooth communication, for example, identify the sensing device 200 through Bluetooth pairing to obtain its identification.

Step S220: The camera installed on the pan/tilt of the camera device 100 is adjusted to face the first direction, the processing module 120 of the camera device 100 determines the first direction information representing the first direction, and establishes the identification of the sensing device 200 and the first direction information The mapping relationship among them; wherein, the adjustment module 130 of the camera device 100 can adjust the rotation angle of the pan/tilt according to the first direction information, so that the camera faces the first direction to implement shooting in the first direction.

Before this step, the camera device 100 should be fixedly installed at the monitoring position by the user, and the pan/tilt of the camera device 100 should be in an absolutely fixed state, and only the camera head can freely rotate up, down, left, and right under control. After the camera device 100 is installed, step S220 can be executed.

In step S220 , the user first determines the first direction to be monitored, and the first direction corresponds to the identification of the sensing device 200 . For example, when the sensing device 200 is installed on a gate, the first direction may be the direction of monitoring the gate. After determining the first direction, the user needs to adjust the camera on the gimbal to face the first direction. After the direction is adjusted, the camera device 100 can automatically determine (the direction the camera is currently facing) the first direction information representing the first direction after a preset period of time, and then establish a relationship between the identification of the sensing device 200 and the first direction information. mapping relationship; or, after the direction is adjusted, the camera device 100 can determine (the direction the camera is currently facing) the first direction information representing the first direction under the user input operation (such as a trigger button), and then establish the sensing device 200 A mapping relationship between the identifier and the first direction information.

Same as the above description of the camera device direction change tracking control method, the first direction information includes horizontal angle information and vertical angle information. Horizontal angle information and vertical angle information are relative to the standard position of the camera. For example, the vertical angle information is a downward rotation angle of α1, and the horizontal angle information is a rightward rotation angle of β1, and both α1 and β1 are relative to the standard position. As mentioned above, when the vertical angle information is α1 angle downward and the horizontal angle information is β1 angle rightward rotation, if the camera is not in the standard position, for example, the camera is in the downward rotation α2 angle relative to the standard position 1. Rotate the position of the angle β2 to the right, then the required rotation angle of the camera can be obtained as the angle α2-α1 downward, and the angle β2-β1 to the right.

Certainly, the first direction information may also be the information of the required rotation steps of the camera, such as the information of the horizontal rotation steps and the vertical rotation steps information. Similarly, the horizontal movement step information and the vertical movement step information are relative to the standard position of the camera. For example, the information on the number of vertical movement steps is X1 steps downward, and the information on the number of horizontal movement steps is Y1 steps to the right. Both X1 steps and Y1 steps are relative to the standard position. When the information on the number of vertical movement steps is X1 steps downward and the information on the number of horizontal movement steps is Y1 steps to the right, if the camera is not at the standard position, for example, the camera is at X2 steps downward relative to the standard position, Move the position of Y2 steps to the right, and the number of steps required to rotate the camera can be obtained as X2-X1 steps for downward movement and Y2-Y1 steps for rightward movement.

In step S220, after the communication module 110 of the camera device 100 obtains the identification of the sensing device 200, it also establishes a mapping relationship between the identification of the sensing device 200 and priority level information. Different sensing devices 200 may have different priority levels. For example, if there are door contacts, window contact sensors, safe door contacts, and smoke sensors, you can set the order of priority from high to low as: smoke sensors, safe door contacts, door contacts, and window shock sensors . Of course, some sensing devices 200 may have the same level, so details will not be repeated here.

In the above method of pairing the camera device with the sensing device, the camera device obtains the identification of the sensor device; the camera set on the pan/tilt of the camera device is adjusted to face the first direction, and the camera device determines the first direction information representing the first direction, and establishes a sensor The mapping relationship between the identification of the device and the first direction information; wherein, the camera device can adjust the rotation angle of the pan/tilt according to the first direction information, so that the camera faces the first direction for recording in the first direction. Through the above method of pairing the camera device with the sensing device, a single camera device can identify the direction of each sensor device according to the identification of the different sensor devices, thereby facilitating the camera device to implement the above camera device commutation tracking control method during monitoring, greatly reducing the Construction costs and maintenance costs.
