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
and maintain the signal quality
• 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

. 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.
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.
SETUP
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
. Be certain that the channel
listed at the top is the one which
the PTZ camera will be connected
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.
STEP 3
. Click the save button once you
have entered the settings. If you are
operating an identical PTZ camera
on another channel, you may use the
Copy
and
Paste
buttons to apply
those settings to the channel that
camera is connected to.
STEP 4
. Once you have saved your
settings and exited the menu, you
can right-click the mouse to bring up
the
Shortcut Menu
allowing you to
select the Pan/Tilt/Zoom controls.
