Multiple KD-C25SRT cameras can transmit wirelessly together without any interference, and there is no distance limitation. As long as there is a wireless network signal, audio and video signals can be transmitted stably, and the picture is clear and smooth, with a delay of ≤150ms, no tailing, KD-C25SRT Camera control and recording are also very good. First of all, the camera's push, pull, pan, tilt, and tilt can be remotely controlled in real time by wireless. The control can be controlled in real time through Kaidi’s full range of video, broadcast, recording, and virtual all-in-one equipment. It also supports wireless tally, and the camera recording can also be controlled remotely through the Kaidi equipment to achieve two-way control of remote control recording, stopping and all the information of the recording. The feedback information includes the recording progress, time, capacity and recording file name, etc.
