It could also reduce the configuration of front and back equipment to reduce the overall construction cost, and promote the video surveillance system to be intensive and efficient. Ordinary waterproof cameras played an important role in road traffic command. They provided intuitive live images for the command center. The operator could fully understand the traffic and public security situation through large screens, computers, and other equipment. In the event of an emergency, they could watch the event process in real time and call the playback video. Its performance and image signal quality directly affected the real-time recording and monitoring effect of the system. Ordinary waterproof cameras have outstanding advantages such as long night vision, high quality, high definition, superior waterproof performance, and comprehensive performance stability.
