At the forum, somewhere was discussed, as a man brought through the NVR weather forecast. I can not find the link! I have a NVR Hikvision DS-7608NI-K2. I want to output the first video on the first channel, which is constantly circling (video open to full screen). When a person appears in the range of any of the cameras Hikvision - the screen displays a picture from the camera. How to submit a stream of video from the computer or from YouTube to the NVR?
