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 accordant with the product type you order.
The label in the real panel is very important for the after service. Please protect it carefully. When you
contact us for after service, please provide the product type and serial number in the label.
2.2 Hard disk installation
For the first use，please install the hard disk.
①disassemble the screw ②disassemble the crust ③fix the screw of hard disk

2.5 Audio and video input and output connections
2.5.1 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 vidicon signal stable and credible
The vidicon 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 vidicon 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 electro magnetic 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.
2.5.2 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 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 electric magnetic 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 creepage of low quality TV can lead
to the damage of other equipments.

2.5.3Audio 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 electric magnetic Interference and connected credible
which avoid false and joint welding and oxidation. The high voltage current should be avoided especially.
2.5.4Audio 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 can not 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.
2.6 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 can not 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.

8308R Series Network DVR User Manual
B. Avoid the entrance of high voltage. Make the layout reasonably. Take precaution from the thunder.
C. In the outlying end connect 120Ωresistance paralleled to reduce the inflection and insure the signal
quality.
D. The 485 AB lines of DVR can not connected with other 485 output equipments paralleled.
E. The voltage between theAB 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
The DVR alarm output port is constant opening type.
