Description

A heat-discharging and waterproof infrared dome camera

【Technical field】

The utility model relates to the technical field of a CCTV closed-circuit television monitoring system, in particular to an infrared dome camera with heat dissipation and waterproof.

【Background technique】

For CCTV closed-circuit television monitoring system, the light condition of the monitoring environment is one of the important reasons that affect the clarity of the monitoring image; for the dark night monitoring environment, the current common practice is to use low-light cameras or install A certain number of infrared lights (LED lights) form auxiliary light sources such as infrared light boards or searchlights to make up for the lack of light at night.

At present, the method to solve the problem that the lighting uniformity and brightness of the night monitoring environment cannot meet the minimum illumination requirements of the monitoring camera is to use a certain number of infrared lights (LED lights) to form auxiliary light sources such as infrared light panels or spotlights and install them in a heavy-duty indoor and outdoor omnidirectional On the PTZ, you can monitor in low light or no light. But this kind of heavy-duty indoor and outdoor omni-directional pan-tilt has a slow rotation speed in the left and right directions, and a small rotation angle in the up and down directions, and has a large volume and a heavy weight, and it has no ability to quickly and sensitively monitor large-scale and long-distance monitoring targets. In order to solve the problem of insufficient ambient light, if an auxiliary light source of an infrared light board can be installed at the camera to achieve synchronous alignment with the monitored target, a clear image can be obtained. The current practice is to add When using auxiliary light sources such as infrared lamps or searchlights, because the camera needs to rotate, there is a certain gap between the camera and the light-transmitting protective cover, and the light directly reflected by the protective cover will enter the camera lens, because the material of the outer protective cover of glass or plastic will reflect light. The reason is that part of the light originally used for auxiliary lighting is reflected or refracted back into the lens of the camera. At this time, it is like using a flashlight to aim at the glass to take pictures, which will cause the monitored image to be unclear. However, the internal components of the ball machine generate heat, so it is usually necessary to install a row of fans and vent holes on the transparent bottom cover. If the vent holes are not equipped with a rain plate, the rainwater will enter the ball machine and get wet when it rains. Electronic components, and rainwater will enter the dome camera along the vent hole of the transparent bottom cover, so once the rainwater enters too much, it will damage the components in the dome camera, and the heat dissipation, waterproof and dustproof of the camera and electronic components will not be realized question.

【Content of utility model】

The purpose of the utility model is to overcome the deficiency of the prior art that rainwater enters the sphere from the vent hole and provide a heat-discharging and waterproof infrared dome camera that can prevent rainwater from entering the sphere through the vent hole and has a simple structure.

As mentioned above, an infrared dome camera with heat dissipation and waterproof is also provided with an exhaust fan for discharging hot air from the exhaust hole to the outside in the imaging area, and the exhaust fan is correspondingly arranged on the inside of the exhaust hole in the transparent bottom cover.

According to the heat-dissipating and waterproof infrared dome camera as described above, the protective plate is arranged on the outer wall of the transparent bottom cover.

As mentioned above, a heat-discharging and waterproof infrared dome camera, the outer wall of the transparent bottom cover is provided with frames at the corresponding ventilation holes and exhaust holes, and the protective plate is arranged in the frame. The bottom surface and the transparent bottom cover leave a gap to facilitate the passage of air.

As described above, a heat-dissipating and waterproof infrared dome camera, the edge of the frame is provided with a plurality of sockets, and the edge of the protective plate is provided with a plurality of posts corresponding to the sockets, and the posts are inserted into the jack and secure.

As described above, a heat-discharging and waterproof infrared dome camera is provided with a dust-proof net between the protective plate and the air hole to prevent foreign matter from entering the transparent bottom cover.

According to the heat-dissipating and waterproof infrared dome camera described above, the protective plate is arranged on the inner wall of the transparent bottom cover.

In the heat-dissipating and waterproof infrared dome camera as described above, the frame is a concave frame recessed into the transparent bottom cover.

Compared with the prior art, the utility model has the following advantages: since the utility model is provided with a frame where the transparent bottom cover is provided with an air vent, a protective plate is arranged in the frame, and there is a gap between the bottom surface of the frame and the transparent bottom cover, An air outlet for the exhaust fan is left under the frame, so it can not only dissipate the heat inside the monitor well, but also prevent the outside rainwater from entering the sphere; The inner wall is also provided with guard plates corresponding to the ventilation hole and the exhaust hole respectively, with double protection to ensure that rainwater cannot enter the interior; the utility model also has the advantages of simple structure and practicality.
