I have one Pelco Spectra 4 SE PTZ connected to a Pelco DX8000 DVR.
Both video and PTZ control is sent through a coax.
The camera has worked for three years but now is failing to move to the left or right.
I rebooted the camera, checked for voltage drops, switched DVR port, checked BNCs.
Sometimes the camera will say "Configuration failed" after a reboot of the camera.
Is this a camera, backboard, or wire issue?
