PAN/TILT/ZOOM CAMERAS CHAPTER 6

6.1 CONNECTING A PTZ CAMERA

The RS485 connector is used to connect and control PTZ cameras. It uses a single-direction protocol meaning that it can send commands out to the camera(s) but not receive any data back from the unit.

The DVR is set by default for RS485 to be disabled for each channel. Therefore, PTZ settings must be enabled before PTZ cameras can be utilized. This system supports 26 of the most common protocols including Pelco-D and Pelco-P.

When connecting a PTZ camera, the following should be taken into account:

• Ensure that the camera has the same grounding with the DVR otherwise you may not be

able to control the PTZ. Shielded twisted wire is recommended with the shielded layer being

used to connect to the ground. Improper grounding may result in chip damage.

• For excessively long wire runs, or if multiple PTZ cameras are connected to the DVR, 120Ω

should be parallel connected between the A and B lines on the far end to reduce reflection

6.2 PTZ CONTROL AND SETUP

The following instructions are based on the Pelco-D protocol. You will need to have the manual for your PTZ camera at hand to ensure the proper settings within the DVR.
