The high-speed camera has a built-in image sensor, an image encoder and a wireless communication interface. The image sensor is used to collect image information of towers and transmission lines. The image encoder digitally compresses and encodes the collected image information. The compressed and encoded information passes through the wireless communication interface. Send to public wireless communication network;

The public wireless communication network is the existing 3G network, and the 3G wireless communication network is the public network. The 3G public network data transmission technology is the abbreviation of the third generation mobile communication technology, which refers to the cellular mobile communication technology that supports high-speed data transmission, including TD- SCDMA, W-CDMA, and CDMA2000. At present, China Telecom's CDMA2000 (3G-EVDO) network is generally used in the south, and China Unicom's WCDMA network is generally used in the north. If you consider signal problems in remote areas, you can use China Mobile's TD -SCDMA/EDGE network.
