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
Voice input impedance is high, so the microphone must be a microphone
connected to the power supply.

VDH-NK205A Hardware Manual
8
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.

phone headquarters, we will guides you how to solve by the machine
type and version of the program.
2. Maintenance
Damped dust on the PCB board will cause a short circuit and will do
something wrong to the NVR or damage it. For long-term stability of the
NVR, regularly brush the circuit boards, connectors, fans and chassis to
remove dust.
Please ensure the project is well-grounded, so images, audio signal will
not be disturbed. At the same time, we can protect the NVR from static
or inductive voltage damage.
Do not remove audio/video cables and RS-484 when the NVR is
powered on, or they will be damaged.
Do not use the TV interface in the NVR video output (VOUT), or the NVR
output circuit will be damaged easily.
Do not turn off the power switch directly to shut down the NVR. Use the
menu shutdown or OFF button on the front panel (press more than three
seconds) to turn off the power automatically to avoid hard Drive crash.
Keep the NVR away from heats and hot places.
Keep the NVR chassis well-ventilated for better heat dissipation.
Have regular checks and system maintenance。
