FIERCE4203 0 Posted November 26, 2010 Have a rayvision dvr hooked up to a speco PTZ. A/B wire soldered to db25 connector at back of dvr. Power is at ptz camera. All settings match. DVR controls PTZ fine, then wait couple hours and dvr will not communicate with ptz. If i turn off DVR and reboot everything will work again leading me to think the problem lies with the dvr. Can anyone advise what voltage I should be getting from dvr to control wires? I heard 5 volts but want to make sure this is my next step. driving me crazy.
