2 Open-package check and cable connections
2.1 Open-package check
When you receive the DVR, please check first.
First, please check whether there is any visible damage to the package
appearance. The protective materials used for the package of the DVR can
protect most accidental clashes during transportation.
Then, please open the box and get rid off the plastic protective
materials. Check whether there is any visible damage to the DVR
appearance.
At last, please open the machine crust and check the data wire in the
front panel, power wire, the connection between the fan power and the main
board.
Front panel and rear panel
The key function specification in the front panel and the interface
specification in the real panel are in the specification.
Please check the product type in the front panel whether is

2.4Audio and video input and output connections
2.4.1 Video input connections
The video input port is BNC connector plug. The demand of input signal
is PAL/NTSC BNC (1.0VP-P, 75Ω).
The video signal must be accorded with the state standard which has
the high signal to noise ratio, low aberration and low interference. The image
must be clear and has natural color in the appropriate brightness.
Insure the camera signal stable and credible
The camera should be installed in the appropriate location where is
away from backlighting and low illumination or adopts the better backlighting
and low illumination compensation.
The ground and power supply of the camera and the DVR should be
shared and stable.
Insure the transmission line stable and credible
The video transmission line should adopt high quality coaxial pair which
is chosen by the transmission distance. If the transmission distance is too far,
it should adopt shielded twisted pair, video compensation equipment and
transmit by fiber to insure the signal quality.
The video signal line should be away from the electromagnetic
Interference and other equipments signal lines. The high voltage current
should be avoided especially.
Insure the connection stable and credible
The signal and shield lines should be firm and connected credible which
avoid false and joint welding and oxidation.
2.4.2 Video output connections and options
The video output is divided into PAL/NTSC BNC (1.0VP-P, 75Ω) and
VGA output (selective configuration).
When replace the monitor by the computer display, there are some

Page 7
issues to notice.
1. Do not stay in the turn-on state for a long time.
2. Keep the computer display normal working by demagnetizing
regularly.
3. Stay away from the electromagnetic Interference.
TV is not a credible replacement as a video output. It demands reducing
the use time and control the power supply and the interference introduced by
the nearby equipments strictly. The creep age of low quality TV can lead to
the damage of other equipments.
2.4.3 Audio signal input
Audio port is BNC connection.
The input impedance is high so the tone arm must be active.
The audio signal line should be firm and away from the electromagnetic
Interference and connected credible which avoid false and joint welding and
oxidation. The high voltage current should be avoided especially.
2.4.4 Audio signal output
Commonly the output parameter of DVR audio signal is greater than
200mv 1KΩ (BNC) which can connect the low impedance earphone and
active sound box or other audio output equipments through power amplifier.
If the sound box and the tone arm cannot be isolated, howling phenomena
is often existed. There are some methods to deal with the above
phenomena.
1. Adopt better directional tone arm.
2. Adjust the sound box volume to be under the threshold that
produces the howling phenomena.
3. Use fitment materials that absorb the sound to reduce reflection of
the sound.
4. Adjust the layout of the sound box and the tone arm.
2.5 Alarm input and output connections
1. Alarm input
A. Alarm input is grounding alarm input.
B. Alarm input demand is the grounding voltage signal.
C. When the alarm is connected with two DVRs or connected with
DVR and other equipments, it should be isolated by relay.
２. Alarm output
Alarm output cannot be connected with high-power load (no more than
1A).When forming the output loop it must prevent the big current from relay
damage. Use the contact isolator when there is a high-power load
３. PTZ decoder connections
A. The grounding of the PTZ decoder and DVR must be shared
otherwise the common-mode voltage will lead to the PTZ control failure.
The shielded twisted pair is recommended.
B. Avoid the entrance of high voltage. Make the layout reasonably.
Take precaution from the thunder.
C. In the outlying end connect 120Ω resistance paralleled to reduce
the inflection and insure the signal quality.

Page 8
D. The 485 AB lines of DVR cannot connect with other 485 output
equipments paralleled.
E. The voltage between the AB lines of the decoder must be less
than 5V.
4. Front equipment grounding note
Bad grounding can lead to the burnout of the chip.
5. Alarm input type unlimited

2.6.1 Alarm input port specification
1 channels alarm input. Alarm input type unlimited.
The grounding and the com port of the alarm sensor are parallel (The
alarm sensor is 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 in external power supply.
2.6.2 Alarm output port specification
1 channels alarm output. There is external power supply when using the
external alarm equipment.
Please refer to the relay relevant parameters to avoid the overload that
damages main machine.
