Section 3.8 Backup
4.8 SHUTDOWN
This is the preferred method to use when shutting down the NVR.
When this window is opened, you have the
option of logging out as a user, switching the
user, shutting down the system or restarting
it.
After selecting
Shutdown
, the NVR will stop
recording, the hard drive will stop and you will
be able to turn it off using the power switch
on the back panel.

CHAPTER 5
5.1 CONNECTING A PTZ CAMERA
Unlike conventional PTZ cameras, IP PTZ cameras do not require a control wire in order
to operate. The NVR can send commands directly through the RJ-45 (Ethernet) cable that
connects the camera to the POE, or via the network. If you are using an IP PTZ camera,
please skip to the section entitled
Control
in
Section 5.2
.
There are still a number of legacy camera mounts and other systems in use which require a
RS485 digital control wire to operate. For that reason your system still includes the option
to connect an RS485 control wire to the back of the NVR. The RS485 connector is used to
connect and control the motion of these platforms. 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 the RS485 can be utilized. This system supports 26 of the most
common protocols including Pelco-D and Pelco-P.
When connecting a PTZ device, 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 oj75
f 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 5-1
.
Multiple control wires can be connected to this
port, but you may require an expander port to
do so.
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.
