First, look at the video format and resolution of the camera;
The SDI monitor used here can directly see the video format and resolution. When the monitor is connected to the camera, you can see that the video format is SDI and the resolution is 1080i 50Hz in the upper right corner.
Then, disconnect the direct connection between the monitor and the camera, connect the camera output to the DVR, and the video format will be displayed in the upper right corner of the monitor after the connection, and the resolution is 1280X1024 60Hz. However, at this time we see that there is no image display (and at this time there is a video signal coming in);
Note: Since the DVR output is in HDMI format, we want to set the monitor input to HDMI format.
So, the problem is that the DVR control menu cannot be seen here. How to change the video output format of the camera to be consistent with the DVR support? Shenzhen Xuan Zhan Technology Co., LTD. ‘s Wells integrated camera has such a function: you can modify the video output format of the camera and DVR without entering the menu. The steps are as follows:
1. Disconnect the camera power
2. Hold down the left key in the control key
3, turn on the camera power, press and hold the left button for 30s and then release, wait a moment to see the image display. (At this point, the video output resolution of the camera will change to 720P 50Hz, while our DVR supports 720P 50Hz)
4, after the image, we can enter the DVR menu > PTZ control, click the page to switch 3 times, and then click into the menu, change the camera resolution (GENERAL SET > FORMAT), and save, and then the camera will automatically restart.

Summary: When we use the SDI camera, we should first understand the video format and resolution supported by the DVR, conversion box, matrix, etc., whether they are the same as the current output Settings of the camera. If different, it will cause a signal, but the image does not display the problem!
