PTZ controls work fine.

12 volts supply is rated at 5 amps

PTZ video is approx. 150 feet on RG59 - siamese twin

Power supply transformer 12v is mounted at the PTZ.

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.

Since you have no dip switches that control the format type you are going to have to access the OSD of the camera using the tool, or something similar. That way you can see what you are doing to change the format.
