Hello, what model PTZ are you using? Could it be a different format. In Europe most DVRs are PAL format and in the USA all DVRs and cameras are NTSC format. when you connect a NTSC camera to a PAL DVR it will cause lines like that.

Is it possible to take a spare camera and connect it there to see if you get video? I also noticed in the specs that the camera is not auto switching for PAL/NTSC.
This is the kicker, until you have video output you wont know. If the camera has dip switches you may be able to select that format, but I don't know for sure. Another option would be to use a

that tool can use both formats and output the video on the monitor.

This PTZ has replaced a working SPECO camera on the same video line. Looks like the line is or was good before the replacement.
Let me know if I should try another switch - not easy to do up a lamp post. I have 3 lines/cameras on the post.
This camera does not have a PAL/NTSC switch. I am trying to get a NTSC chip from the manufacturer.
Not sure if the problem is PAL but picture keeps rolling very fast. RS485 works fine to move the camera.
