Mark watermark camera can be used to add mark watermark to the monitoring screen, which can include cell name, date, time and other information for tracking and identification. Patrol personnel can check the real-time monitoring screen through mobile phones or computers to ensure the safety of the community. If an abnormal situation is found, corresponding safety measures can be taken in time, and the watermarked monitoring screen can be saved as evidence.
