ok i replaced 4 old ptz indoor domes with new pelco spec iii a few weeks ago.. put them all in and used the current data and video wiring back to the dvr and to an existing pelco kbd360 controller. after toning out a few lines coming back to the security room we got everything hooked up correct and working - there are a total of 7 ptzs.

next week they call and one of the ptz is not moving. go back yesterday to check it out and find out that someone had been trying to clean up the old wiring that ran from the new ptz in the drop ceeling out a door into a stairwell and was running next to pipes. they had cut the data wire and tried to piece it back together but didnt do it right and thats where the problem was.. so we patch it back together and go upstairs to the room and its workign but now # 4 and 5 ptz arent working..... all ptz come back on their own data line to the room except 6 and 2 are on the same line. we connect each ptz by itself to the controller and they work but when we connect them all to the controller one or 2 dont work!!! this post could go on a bit longer but i dont know what to do other than try and get all ptzs on their own line coming back to the controller.. any advice???

possibly the controller got "zapped" when the wires were cut and that caused the controller to short out and it is now causing the problems you have. Try another controller.......

i had kind of the same problem one time. One time I unplugged the controller because we could not control the ptz and the picture obviously wen away. Well after plugging it back up and everything I could not get the picture back up. Want to know what worked? What vst man said,,,,,a new controller. try that

yeah thats the plan this week switching out the older controller and seeing if things magically work again

stay tuned!

oh btw was out saturday here in chicago in single digit temps installing one outdoor spec 3 and one fixed on the roof on a scrap yard tower.. im just now thawing out!!!
