3. Installation Illustration
Video input
Input interface is BVC type; input signal is PAL/NTSC BNC（1.0VP-P，75Ω）.
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.
Cables and shielded cable should be well-connected firmly to avoid false,
joint welding or oxidation.
Connections for video outputs
The video outputs include PAL/NTSC BNC(1.0VP-P，75Ω), 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
VDH-DXA Series Hardware Manual

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.
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 DVR 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 cannot achieve spatial
segregation, it is prone to the phenomenon of whistling.
You may adopt 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 DVRs or connected to a
DVR and other devices, it should be isolated by relays.
2. Alarm OUT
The alarm output of the DVR cannot 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.
