PTZ can't store video, is PTZ the same as normal surveillance in storing video?

The difference between a PTZ and an ordinary camera is just that there is more than one platform that can adjust the direction. The output video is the same, as long as that way can show the image is normal, not video only may be the problem of setting.

You can change the video header, which is the one plugged into the video card. You can swap the header of the headend and the normal one, and then you will know the problem.
