CONNECTING A PTZ CAMERA
Setting up a PTZ Camera is simple. The XVR unit comes preassembled with an internal PTZ adapter. The cabling may be run up to
4,000 ft using 22 Gauge Twisted Pair.
It is important to understand how the PTZ connects to the XVR. The XVR outputs an RS-232 signal and converts in to an RS-422/485
signal which is then sent to the PTZ camera.
Attaching the RS-422 Adapter – 16 Channel
1. Locate the PTZ adapter cable
2. Connect the wires of the PTZ adapter to the PTZ camera. The
red wire should connect to the RX+ on the camera and the brown
wire should connect to the RX-.
NOTE: The PTZ adapter has four wires but only two are necessary for
this application; the yellow and orange wires are not used currently.
3. Connect the other end of the adapter to the XVR unit as shown.
4. Assign the PTZ camera an ID number that coincides with the
number assigned to it by the XVR unit
Example: If the camera is plugged into input number 5, set the PTZ
unit to ID number 5.
Attaching the RS-485 Adapter – 4 Channel
1. Locate the PTZ adapter cable.
2. Connect the two wires of the PTZ adapter to the PTZ camera.
The red wire on the adapter should connect to the RX+ on the
PTZ and the brown wire should connect to the RX-.
3. Connect the other end of the adapter to the XVR unit as shown.
4. Assign the PTZ camera an ID number in PTZ Setup that
coincides with the number assigned to the camera. This is
normally done utilizing a dip-switch configuration method on the
addressable dome.
Tip: It is recommended that the ID of the camera coincide to the input
number on the DVR. This will make future troubleshooting and
configuration less complex.
