Affordable Video

I appreciate everyones review of my problem. I think I got it figured out. The camera I will be replacing is 10 years old and the model number was dd5tac. Apparently a Spectra model camera will work in it's place. I have ordered one and will be holding my breath until it is working. Thanks again,

I am in a really big jam if anyone can help me. I recently put in a bid to replace a PTZ camera that had broken in a Highschool gym. I got the new camera and when I took down the old one I found that there was only one Coax cable, and two 24v power cables. I know that the old PTZ was fully functional prior to breaking. Due to the layout of the school It is impossible for me to run a new CAT5 cable for DATA. The 24v power supply is not near the DVR (computer base), so there is no way to use the power cables for data and set up new power supply. The original camera was 9 years old (unknown make and model). How can I use the PTZ feature with only one Coax Cable? Affordable Video Security.com

I appreciate everyone's input. The camera had the following information, which I cant seem to find the exact model, but I just need something that will work: MFG By PELCO, CLOVIS, CA, USA Model: DDTAC freq: 60 hz Watts: 17 Volts: 24vac ref: 4.63 The software used is ADVENT - and the some of the cameras feed into a rack mount device that didn't have any markings other than on the back it had the following Ports: LAN, COM, SW1, and in and out BNC connectors. I have photos to show but cant get them loaded. I am embarrassed to say that I am in over my head a little on this one. Thanks,

This school surveillance system is a mess. I traced the power supply back to the source and it is a power supply in the same building. The Coax runs to another building under a parking lot and a small stream through a 4 inch conduit to the computer DVR that uses ADVENT software. I am not as educated as I should be on the PTZ and the different protocol. I will try and get some detailed information on the computer DVR Set up. THANK YOU! Please check back with me, and offer any other thoughts you may have.
