I have two PTZ cameras at a cusomers one is about 3 years old and the other is new I have them set at 9600 baud pelco P and they have addresses 1 and two I cannot control them from the same control board but I can hook up a seperate controller enter the address and it works fine. the supplier is willing to send me a new camera but changing them out will not be easy. I could use the geovision box but the customer does not want to do that. Any idea why the two cameras don't work when using the same controller?

What controller are you using? Also what DVR controls are you using, brand of DVR etc. What model PTZ's?

Sounds like a protocal issue. Definatly need to know what the ptz models are. If the dvr controls one on pelco p and the new ptz works on pelco p then there shouldn't be a problem I would double check the setting and specs.

baud rate or termination

Thanks will track down mfg do you mean the 120 Ohm termination on the last camera or do you mean a connector problem?

last cam termination
