Multiple kd-c25srt cameras transmit wirelessly without any interference or distance limit. As long as there is a wireless network signal, audio and video signals can be transmitted stably. At the same time, the picture is clear and smooth, the delay is ≤ 150ms, and there is no tailing. Kd-c25srt camera control and recording are also very good. First, push, pull, shake, tilt Yangyang can be controlled remotely and wirelessly in real time. The control can be controlled in real time through Kaidi's all-in-one collection, broadcasting, recording and broadcasting machine and virtual all-in-one machine, and supports wireless tally. The recording of the camera can also be controlled remotely through Kaidi's equipment to realize the feedback of all information of remote control recording, stop and recording. The feedback information includes recording progress and time, Capacity size, recording file name, etc.
