2. Unpacking
When you receive the product, check first whether the packing of the
equipment has obvious damage. The protective material used for the package
during transport can cope with most of the accidental impact
Then, take out the device, remove the protective film of the digital video
recorder and check if there is any visible damage;
Finally, open the case, check the front panel data cable, power cord, power
supply fan and motherboard to see if they are connected firmly.
Front/Rare panels
The key functions of the front panel and the interfaces of the rear panel are
described in detail in the manual.
Please carefully check the plate or foil on the rear panel of the product to see
if it is the model you ordered.
Inside check
In addition to checking for visible signs of damage, be careful to check the
connections between the front panel data cable, power cord and
motherboard.

Video input
Input interface is RJ-45 type; input signal is IP CAM
The Video signal should comply with national standards, a higher signal to
noise ratio, low distortion, low-interference; clear images, no deformation,
nature color and appropriate brightness.
Make sure stable and reliable signals from cameras
Cameras should be installed in a suitable position to avoid backlighting,
low-light environment, or adopts the better BLC, low-light cameras.
Cameras and digital video recorders should be common ground, stably and
reliably, in order to ensure the normal operation of the cameras.
Make sure the transmission cables are stable and reliable
Adopt high-quality, well-shielded coaxial cables, and choose the right model
based on the transmission distance. If the distance is too far, use shielded
twisted pair, video compensation equipment, optical transmission and other
ways to ensure signal quality based on the specific circumstances.
Video cable should avoid strong electromagnetic interference with other
devices and circuits, in particular, should avoid the current of high voltage.
Make sure the connectors well-connected:
Cables and shielded cable should be well-connected firmly to avoid false,
joint welding or oxidation.
Connections for video outputs
The video outputs include VGA and HDMI interfaces.
Pay attention to the following when you select a PC display instead of a
monitor.
1. Do not remain switched on for a long time to extend the life of the
equipment;
2. Regular degaussing will help to maintain the normal operation of the
monitor.
3. Keep away from equipment with strong electromagnetic interference.
Using TV as video output device is an unreliable alternative. It is also
required to minimize the time of use and strictly control the power, the
interference caused by neighboring devices. Leakage risks of low quality TVs
may result in damage to other equipments.
Audio Inputs
VDH-NK300 Hardware Manual
8
Voice input impedance is high, so the microphone must be a microphone
connected to the power supply.
Like video input, voice transmission cables should avoid interference, fake,
poor contact, and special attention to prevent the current of the
high-voltage.
Audio Output
The audio output parameters of NVR are generally greater than 200mv 1KΩ
(BNC), you can directly connect to the low impedance headphones, powered
speakers or other sound devices through a power amplifier.
When the external speakers and microphones can not achieve spatial
segregation, it is prone to the phenomenon of whistling.
You may adopt the following actions,
1. Using better directional microphones
2. Adjust the speaker volume to make it lower than the value of the
generated howling.
3. Using sound-absorbing materials for decoration to reduce sound
reflections and improve the acoustic environment;
4. Adjusting the layout of the microphone and speakers can reduce the
whistling.
AlarmIn/AlarmOut connections
Pay attention to the following before installation.
1. AlarmIn
(a) Alarm input is grounding alarm input
(b) The alarm input signals require voltage signals to the ground
(c) When the alarm device is shared with two NVRs or connected to a
NVR and other devices, it should be isolated by relays.
2. Alarm OUT
The alarm output of the NVR can not be connected with high-power
load (no more than 1A). In the output circuit, be careful about the
excessive current that may cause damage to the relay. When using
high-power load, extra relays are needed.
