2 Installing the Device
Preparation
Checking the Device Package
Before you install the device, verify the device model and check the
components and their quantity against the packing list to make sure all
items listed are included in the package.
WARNING!
Do not remove the dismantlement-preventive seal from the device
chassis cover without permission. To open the chassis, contact your
dealer. Otherwise, we shall not be held liable for any consequence
caused thereby.
Checking the Installation Environment
The device can be installed indoors only, and must meet the following
requirements:
Use correct lightning protection devices for the device power
source, audio/video signals, and RS-485 ports.
Ground the device correctly through the grounding screw. For
more information, see the Encoder and Decoder Cable Connection
Guide.
Cable Requirements
NOTE!
For information about how to select the common cables, contact your
dealer.

8
VGA cables
Use UL-certified VGA cables with shielding rings and gold-plated
connectors.
Use cables with pure copper or oxygen-free copper shielded with
tinplated layer. The wire gage of the core conductor should be in
the range of 24 AWG to 28 AWG. A smaller gage means a thicker
wire diameter and a better transmission effect.
The transmission distance of an ordinary cable is 15 meters (49.21
ft), and that of a better project-level cable can be 50 meters
(164.04 ft).
HDMI cables
Use HDMI Association-certified HDMI cables with shielding rings
and gold-plated connectors.
Use cables with pure copper with 96 copper braiding or more. The
wire gage of the core conductor should be in the range of 24 AWG
to 28 AWG.
If you use an HDMI cable longer than 10 meters (32.81 ft) to
transmit 1080P signals, you are recommended to use 24 AWG. If
you want to transmit signals for 20 meters (65.62 ft) or longer, you
are recommended to use an HDMI signal amplifier or HDMI
extension cord.
DVI cables
A DVI connector can transmit multiple types of video signals, and
different cables are used for different signals. If the DVI connector is not
connected to an adapter, the requirements for DVI cables are similar
with those for HDMI cables.
Audio cables
Use 4-wire shielded cables (RVVP) or unshielded digital communication
cables (UTP). The sectional area of the cable conductor should be large,

9
for example, 0.5 mm2. You are recommended to use dedicated shielded
audio cables, and the cable length is 100 meters (328.08 ft). Commonly
used audio cables include RCA audio cables and ordinary coaxial cables.
Alarm cables
Twisted pair cables are recommended. The wire gage of the insulated
core conductor should be in the range of 22 AWG to 28 AWG (24 and 26
AWG are recommended). The maximum DC impedance must not be
more than 100 ohm.
The following table shows the maximum length of alarm cables for wire
gages, taking 100 ohm as the benchmark.
Table 2-1 Maximum alarm cable length for different wire gages
Wire gage (AWG)
Maximum cable length
22
1453 m (4767.06 ft)
24
914 m (2998.69 ft)
26
570 m (1870.08 ft)
28
360 (1181.10 ft)
Network cables
Use twisted-pair cables. Currently, twisted pair cables include
unshielded twisted pair (UTP) and shielded twisted pair (STP). STP cables
are shielded with aluminum foil for radiation reduction purpose. STP
cables are more expensive than UTP cables, and they are harder to
install.
Ground wire
The length of the ground wire should be no more than 30 meters (98.43
ft), and its impedance must be less than 5 ohm. For more information,
see Standard YD5098.

Installing the Device in a Rack
NOTE!
You can install your device in a standard 19-inch rack. The rack
should meet the requirement on bearing the weight of the device
and its accessories. The following section uses a standard 19-inch
rack as an example.
Before the installation, make sure the rack is stable and correctly
grounded, and make sure there are no obstacles that might hamper
the installation inside or near the rack.
You can front-mount or rear-mount your device in a standard 19-inch
rack with mounting brackets.
Installing the device to a rack does not require sliding rails or a tray. The
mounting brackets can bear the weight of the device.
The following describes how to front-mount the device. The
rear-mounting method is similar, and thus not provided in this manual.
Preparing for the Installation
Examine the grounding and stability of the rack, determine the
device installation position in the rack, and make sure there are no
obstacles that might hamper the installation inside or near the
rack.
Move your device to a place near the rack.
Installing the Mounting Brackets
Checking before the installation
Mounting brackets are placed in the accessory package with screws.
Each device is shipped with two identical mounting brackets.

12
Installation procedure
1. As shown in Figure 2-2, put the screw-hole side of the bracket
against the chassis tightly, align the screw holes on the bracket
with those on the chassis, and then fix the bracket to the chassis
tightly with two M4*8 screws.
2. Use the same method to install the other mounting bracket.

Installing the Device in the Rack
Place your device horizontally to a proper position in the rack, and align
the mounting brackets along the front posts of the rack. Put the screws
through the waist-shaped holes to contact the floating nuts on the front
posts, and fix the mounting brackets to the front posts of the rack, as
shown in Figure 2-3.
