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.
