Hard Disk Installation
The hard disk is not included in factory configurations. Users can mount a suitable hard disk by calculating
its capacity referring
to “Appendix 5.2 Methods of Calculating HDD Capacity”.
1) Installation procedure
*Open the DVR case. Mount the 4 shock absorption washers into the clamping slots in the case. (If included,
they are not necessary for operation)
*Connect the HDD data cable and HDD power cable to HDD.
*Attach the hard disk to the shock absorption washers by aligning installation holes to the case, hold and fix
them by 4 M3*12 Head Screws plus plain washers.
*Connect the HDD data cable and HDD power cable to the correct interfaces on the main board.
*Replace the DVR top cover, and attach it with the included screws.
Note1
: Please use a HDD that is rated for security camera systems and purchase from a reputable retailer to
ensure quality. See
http://kb.zmodo.com/article.php?id=176
for assistance choosing a hard drive.
Note2
:
Please format HDD after installation, or the system will show an error notification of
“Hard disk error”
accompanied by an audible alarm. Please see 4.9 Maintenance for details.

Rear Panel Connection
*Power Input
Connect power adapter to Power Input interface of DVR. Confirm that the DVR power supply input switch is
positioned correctly for the local voltage before connecting and powering on the unit.
Turn on the unit by flipping the switch on the power supply. The power LED will light if the power cable is
connected correctly.
Note
: Please use the power adapter contained in the package(Output will read 12v/5a).
*Video Input
The video input interface is a standard BNC socket, 1Vp-p, 75
Ω.
Note
: The video signal cable should be kept away from any interference such as electromagnetism.
*Audio Input
The audio input interface is standard RCA socket, 2Vp-p, 600
Ω.
Note
: The audio input resistance is a little bit high; please use active sound collection device or active
microphone. The audio signal cable should be kept away from any interference such as electromagnetism.
*Network Input
The network input interface is RJ45 10/100M self-adaptive.
Note
: Confirm that the network band width is enough for transmitting high definition image smoothly. A 4 or 8
channel DVR will require 512kbps upload and a 16 channel DVR will require 1mbps upload speed from your
ISP.
*Alarm Input and Output
The alarm input device should be the type of GND connected alarm or voltage input alarm, which can be set
as N/O. or N/C.
The requirements for the signal input level for voltage input alarm type is: low level: 0
～
2V; high level: 5
～
15V.
The green angle pins of the signal cable are supplied for access of PTZ and alarm devices. Please
follow these steps to connect:
1. Pull out the angle pins that inserted in the alarm input and output interfaces.
2. Screw out the screws by micro Philips screwdriver, insert the signal cable into interface under spring, and
then tighten the screws.
3. Plug in the connected pins into green angle pin socket.
*PTZ Input
Connect the PTZ control interface to RS485 interface on rear panel. The connection method is similar as
above.
Note:
Please refer to PTZ manual for setting specific parameters, for some PTZ devices contain multiple
telecommunication protocols, baud rates and IDs.
*Video output interface:
TV(BNC) and VGA.
Note:
VGA and TV cannot be selected in the operation interface simultaneously, but may be switched by the
mouse, front panel, or remote control in the menu.
