The most guaranteed way to understand if a security CCTV/IP camera is working is to check if it generates a stable video stream at a certain bitrate. You can monitor the RTSP stream bitrate if the camera or DVR supports the protocol.
With our program, you can receive the RTSP traffic from a IP camera or DVR/NVR, measure, analyze the bandwidth, and compare with the threshold rate.
For that, we should set the minimum acceptable value of the video stream bitrate. If it falls below, the program will have to raise an alarm.
The normal bitrate for each camera is determined empirically, based on several measurements at different times of the day.
To do this, you simply test the camera in different conditions: in the snow, rain, during the day, at night and measure the bitrate on charts displayed by the program.
The threshold value should be set to the lowest measured value, reduced by a certain amount.
It will be individual for each camera and will depend on the image resolution, used codecs, and the scene observed by the camera.
If the video stream bitrate is too low, this may mean that the camera is clogged with snow, is directed in the wrong direction, or does not produce the picture of the required quality for some other reason.
The IP camera or digital video recorder manufacturer is not principal (this can be Hikvision, HiWatch, Bosch, Axis, Hanwha Techwin, Ivideon, Dahua, IDIS, etc.).
