2 Open-box and cable connections
2.1 Open-box
When you receive the DVR, please verify the following:
First: Please check whether there is any visible damage on the package appearance. The protective
materials used for the package of DVR can protect against most of the accidental clashes during the
transportation phase.
Second: Please open the box and get rid of the plastic protective materials. Verify whether there is
any visible damage to the appearance of DVR.
Third: Please open the DVR case and check the data wires in the front panel including power wire
and the connection between the hard drive and the main board.
2.2 Hard disk installation
For first time use，please install the hard disk.
①Remove the case screws ② Disassemble the cover ③ Remove screws of HDD
④ Adjust HDD position ⑤ Connect HDD data wires ⑥ Screw HDD on the case

2.5 Audio and video input/output connections
2.5.1 Video input
The video input port is BNC. The input signal should be PAL/NTSC BNC (1.0VP-P,75Ω).
The video signal must be set according to the state’s standard: a high noise signal ratio, a low aberration
and a low interference. The image must be as clear as the natural color in the appropriate brightness.
2.5.2 Video output
The video output is divided into PAL/NTSC BNC (1.0VP-P,75Ω) and VGA output (Optional).
If you replace the monitor by the computer display, there are some tips to keep in mind:
1、Do not turn on your monitor and keep it in a passive mode for a long time.
2、Stay away from the electro magnetic interference.
TV is not a credible replacement for the video output. It is necessary to reduce the using time,
control the power supply and the interference around your equipment. The creepage of low quality TV
can damage other equipment.
2.5.3 Audio input
The audio port is BNC. The audio signal line should be firm and away from the electro magnetic
interference and properly connected to avoid false connection, joint welding and oxidation. High voltage

Page 7
7
current should be avoided.
2.5.4 Audio output
Normally the output parameter of your DVR audio signal is stronger than 200mv 1KΩ(BNC).
You should use power reverter to connect low impedance earphones, speakers or other audio devices.
2.6 Alarm input/output connections
１、Alarm input
A. Alarm input is grounded input.
B. Alarm input demand is the ground voltage signal.
C. When the alarm is connected with two DVRs or connected with a DVR and other equipments, it
should be isolated by relay.
２、Alarm output
Alarm output can not be connected with a high-power load (no more than 1A). In case there is a
high-power load, use a contact isolator to prevent relay damage.
３、PTZ decoder connections
A. The grounding of the PTZ decoder and DVR must be shared, otherwise the common-mode
voltage will lead the PTZ to control failure.A shielded twisted pair is recommended.
B. Avoid the entrance of high voltage. Make a reasonable cable layout and take precaution in case
of thunder and lightning.
C. In the outlying end, parallelly connect 120Ω resistance to reduce the inflection and insure the
signal quality.
D. The 485AB lines of the DVR can not be parallelly connected with other 485 output equipment.
E. The voltage between theAB lines of the decoder must be less than 5V.
4 、 Grounding note
Bad grounding could lead to the chip’s breakage.
5 、 Alarm input type unlimited
The DVR alarm output port is in “normal open mode”.

The grounding and the COM port of the alarm sensor are parallel (The alarm sensor uses an
external power supply) .
The grounding of the alarm and the DVR should be shared.
The NC port of the alarm sensor must be connected with the DVR alarm input port.
The grounding of the power supply and the alarm sensor must be shared when used with an
external power supply.
2.6.2 Alarm output port specification
The external alarm equipment requires an external power supply.

3 Basic operation
3.1 Turn on
Plug the power supply and turn on the power supply switch. Notice the power supply’s indicator light,
if turned on this indicates the video recorder is turned on. After the startup you will hear a “beep” sound.
Note: 1. Make sure the input voltage corresponds with the switch of the DVR power supply.
2. Power supply requires: 220V±10% /50Hz.
It is suggested to use a “UPS” to protect the power supply.
3.2 Turn off
There are two ways to turn off DVR. The first way, called “soft switch”requires entering the [main
menu] and choosing [turn off] in the [turn off the system] option. The second way requires directly
pressing the power supply switch.
Illumination:
1、Auto resume after power failure
If the DVR is abnormally shut down, it can automatically backup previous video and resume the
working status.
2、Replace the hard disk
Before replacing the hard disk, the power supply switch in the rear panel must be turned off.
3、Replace the battery
Before replacing the battery, the setting information must be saved and the power supply switch
in the rear panel must be turned off. The DVR uses “button” battery. The system time must be
checked regularly; if the system’s time is not correct please replace the battery. It is recommended to
replace the battery every year and use the same battery type.
Note: The setting information must be saved before replacing the battery otherwise information
will be lost.

**Detailed Installation
1. Cable Installation
This section will guide you to connect the cables of your PTZ camera to DVR.
Your PTZ camera cable should split into 3 parts.
1. The first cable is the power supply. This cable must be simply plugged into the wall.
2.The second cable is the “input cable”, which must be plugged in the back of your DVR in the green
slot on the bottom left of the DVR Box. This cable divides into a positive and negative smaller cable. The
negative cable must be plugged into the “B slot”; the positive cable must be plugged in the “A slot”.
Note: Make sure which is the negative and positive cable of your PTZ camera
To plug the yellow and green cables, make sure to correctly stick them in the “A” and “B” slots by
making them stuck in the holes. To do this please use a sharp utensil to press on the yellow clips. By
pressing on the yellow clips on top of the A and B slot, you will be able to stuck the yellow and green
cable.
3. The third cable of your PTZ camera must be plugged into the BNC cable. The BNC cable has 2
end sides. On one end connect the PTZ camera cable. The other end of the BNC cable must be
plugged into the back of the DVR in one of the channel slots. The red plug is useless so plug the
