5.1 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 NVR 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:
• Shielded twisted wire is recommended with the shielded layer being used to connect to the
ground. Improper grounding may result in chip damage. We recommend using CAT 5 or CAT
6 wire for this purpose.
• The 485 port of this NVR 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 two wires of the data cable from the PTZ camera must be inserted into
the ports labeled A & B as shown in
Picture 6-1
. Multiple PTZ cameras can be
connected to this port, but you may require an expander port to do so.
A B
STEP 2
. The color of these leads will
vary by manufacturer but they should
be labeled “
+
” or positive and “
-
” or
negative. The positive wire should be
inserted into port A with the negative
going into port B.
The insulation on both leads should be stripped to expose about 1/8” or 4mm of bare
metal. You must push in the orange tab above the port with a small item like the end of
a paperclip while inserting the wire lead. When the wire is sufficiently inserted, release
the orange tab. Pull gently on the wire to ensure that it is locked in the port.
STEP 3
. Connect the other end of the cable to the proper pins in the connector on the
camera
STEP 4
. Connect the camera video and power cables as you would any other camera.
5.2 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 NVR.

For ease of set-up, the PTZ camera’s video feed should be displayed on the screen.
STEP 1
. Open the
Pan/Tilt/Zoom
Menu
from the
Settings
menu. You
cannot use the
Shortcut Menu
to
access the PTZ controls until after
you have configured a channel to use
PTZ.

STEP 2
. If the PTZ Camera is to be
connected directly to the NVR, then
select Local in the PTZ Type pull
down. Otherwise, select Remote. Be
certain that the channel listed at the
top is the one which the PTZ camera
will be connected to.
For a local PTZ camera, you will need
to enter data into the other fields
according to the data provided in
your PTZ camera’s manual, including
protocol, data bits, stop bits and
parity.
