during transport can cope with most of the unexpected hit;
Then, remove the device, remove the plastic protective film NVR, check whether there is any visible damage to
the outside;
Finally, open the case, check the front panel data cable, power cable, power supply and motherboard fan connector
is loose.
Front panel and rear panel
Various interfaces on the front panel and the rear panel of the various key functions are described in detail
in the specification;
Please check carefully whether the product model on the front panel with foil products you ordered the
same model;
Label affixed to the rear panel, has a very important significance for our service work, please protect. In the
company's after-sales service when you contact us, you will need to provide the model and serial number to
order the label.
Check
In addition to checking for any obvious signs of damage, but please pay attention to check the front panel
data cable, power cable and the motherboard connection is loose.
2.2 Hard disk installation
When you use, first install the hard drive, the machine can install two hard drives inside (capacity no limit).

2.3 Shelf Installation
This product chassis specification is standard 1u, so it can be installed in the standard shelf.
Installation steps and attention items:
1. Make sure the temperature in the room lower then 35℃ (95°f).
2. Keep the equipment has 15cm (6 inches) space around in order to air's circulation.
3. From bottom to shelf installation.
4. When multiple components install in the frame，please take preventive measures to avoid power socket
overload.

2.6 Audio & Video input and output connections
2.6.1 video input
NVR video input port to the BNC input signal requirements: PAL / NTSC BNC (1.0VP-P, 75Ω).
Video signal should comply with national standards, a higher signal to noise ratio, low distortion, low
interference; image must be clear, invisible change, real and natural colour, brightness is appropriate.
Ensure stable and reliable camera signal:
Cameras should be installed in a suitable location, to avoid backlighting, low light conditions, or the use
of good results backlight compensation cameras, low-light cameras.
Camera and NVR power supply should be common ground, and reliable, in order to ensure the normal
operation of the camera.
Ensure stable and reliable transmission line:
Using high-quality, shielded coaxial good video, and based on the transmission distance to choose the
right model. If the distance is too far, should be based on the specific circumstances, the use of twisted
pair, add video compensation equipment, fibber optic transmission and other ways to ensure signal
quality.
Video signal line should avoid strong electromagnetic interference to other equipment and lines,
especially should avoid high-voltage current string into.
Lugs ensure good contact:
Signal and shield lines should be firm, well-connected, avoid Weld, lap welding, to avoid oxidation.
2.6.2 Select and connect the video output device
Video output is divided into PAL / NTSC BNC (1.0VP-P, 75Ω) output and VGA output (VGA is optional)
Choose to use computer to replace the monitor should pay attention to the following questions:
1. Do not keep long boot state to extend the life of the equipment;
2. regular degaussing, which will help maintain the normal operation of the display;

10
3. Away from strong electromagnetic interference devices.
Use TV as a video output device is an unreliable alternative. It also requires minimizing the use of time
and strictly controls the interference power caused by neigh boring devices. Inferior TV leakage risks
may cause damage to other equipment.
2.6.3 SDI video output
Some models support coding for 1080P (720P) SDI video.
2.6.4 Audio input
BNC connector (only one to support intercom function)
Audio input impedance is high, and therefore must be used active pickups.
Similar to the video input audio transmission requires line to avoid interference, avoid Weld, poor
contact, and special attention to prevent a string of high-voltage current into.
2.6. Audio output
Audio output signal parameters is generally greater than 200mv 1KΩ (BNC), you can directly connect
the low impedance headphones, powered speakers or other sound through power amplifier output
devices. In the case of external speakers and microphone cannot be achieved spatial isolation, it is easy
to produce output howling phenomenon. At this point the measures to be taken are:
1. The use of directional better pickups;
2. Adjust speaker volume, making it lower than the threshold to produce the whistle;
3. Multi-use environment using sound-absorbing materials decoration, reduce the reflection of the
sound, improve the acoustic environment;
4. Adjust the layout of pickups and speakers, but also can reduce the occurrence of howling
situations.
2.7 Alarm input and output connections
Before connecting the device, please note the following:
* Note: Some Series devices without alarm input and output functions.
2.7.1 Alarm Input
Alarm input is grounding alarm input;
Alarm input requirements for ground voltage signal;
When the alarm is connected to two NVRs or simultaneously access the NVR or NVR and other devices,
need to be isolated by relay.
2.7.2 Alarm Output
NVR alarm output cannot be connected power load (no more than 1A), should constitute the output
loop current is too large to prevent damage to the relay. Require the use of high-power load contactors
isolation.
2.7.3 PTZ decoder connected
A. must do PTZ decoder and NVR common ground, otherwise there may be common-mode voltage will
lead to control PTZ. Recommended to use shielded twisted pair with shielding for common ground
connection;
B. prevent high voltage in series, rational layout, good lightning protection measures
C. to be incorporated into the 120 ohm resistor in the remote reduced reflection, to ensure signal quality;
D. NVR 485AB line cannot be connected with other 485 output;
E. AB line voltage between the decoder requires less than 5V.
2.7.4 Front-end device requires grounding
