7.1 CONNECTING A PTZ CAMERA

All QT-Series DVRs can support one or more Pan/Tilt/Zoom, or PTZ cameras. These cameras

connect to the DVR through the same ports as a conventional camera, but the control wires

connect through the RS485 block on the back of the DVR. Picture 7-1, below, is only

a representation and your actual connector may look different. Please consult Chapter 2

Connections and Controls to ﬁnd the diagram representing your model for the location of

your connector block.

The RS485 connector 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 meaning that video images

will be delivered through the video cable as with any other camera.

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:

• The 485 port of this DVR cannot parallel connect with the 485 port of another device

• The voltage between the A and B lines of the camera should be less than 5V.

STEP 1. The data cable from the PTZ

camera must be connected to

the ports highlighted in Picture

7-1. Multiple PTZ cameras can be

connected to this port, but you may

require an expander port to do so.

STEP 2. Connect the other end of

the cable to the proper pins in the

connector on the camera

STEP 3. Connect the camera video and

power cables as you would any other

camera.
