Connecting a PTZ Camera to a DVR Using Cat-5 Cable.
- Remove a small portion of the insulation at both ends of the Cat-5 cable.
- Once the insulation is removed, you will see that the Cat-5 cable is actually several pairs of wire bundled together. You should see a solid-colored wire and a white wire with a colored stripe next to the colored wire (e.g. a blue wire and a white wire with a blue stripe).
- For the purpose of connecting a PTZ, it doesn’t really matter if you use the solid color wire or the striped wire for positive or negative. You just want to make certain you are consistent (i.e. if the solid color wire is connected to the positive at the PTZ, the solid color wire must be connected to the positive at the DVR as well.)
- Twist one wire to one of the loose wires coming from the PTZ. Then connect the other wire in the same fashion. To make certain you keep a solid connection, you may want to use wire nuts or b-wire connectors (“beanies”).
- Connect the Cat-5 wires, using the same pair as is connected to the PTZ, to the rs-485 port on the back of the DVR. In the case of multiple PTZ’s, it is possible to daisy-chain all the Cat-5s together to connect to the rs-485 port.
- Congratulations! You have now successfully connected your PTZ control wires to your DVR.
