The video input interface is BNC. The input video format includes: PAL/NTSC BNC(1.0VB
P- P
,
75Ω.
B
The video signal should comply with your national standards.
The input video signal shall have high SNR, low distortion; low interference, natural color and suitable
lightness.
Guarantee the stability and reliability of the camera signal:
The camera shall be installed in a cool, dry place away from direct sunlight, inflammable, explosive
substances and etc.
The camera and the DVR should have the same grounding to ensure the normal operation of the camera.
Guarantee stability and reliability of the transmission line
BTTTB
Please use high quality, sound shielded BNC. Please select suitable BNC model according to the
transmission distance.
If the distance is too long, you should use twisted pair cable, and you can add video compensation devices
or use optical fiber to ensure video quality.
You should keep the video signal away from the strong electromagnetic interference, especially the high
tension current.
Keep connection lugs in well contact.
B
The signal line and shielded wire should be fixed firmly and in well connection. Avoid dry joint, lap welding
and oxidation.
Connecting Video Output
Video output includes a TBNC(PAL/NTSC BNC(1.0VP- P, 75Ω)output and a VGA output.
System supports BNC and VGA output at the same time. See X284H284H284HError: Reference source not foundX.
When you are using pc-type monitor to replace the monitor, please pay attention to the following points:
To defer aging, do not allow the pc monitor to run for a long time.
Regular demagnetization will keep device maintain proper status.
Keep it away from strong electromagnetic interference devices.
Using TV as video output device is not a reliable substitution method. You also need to reduce the working hour
and control the interference from power supply and other devices. The low quality TV may result in device
damage.
These series products adopt BNC port.
Due to high impedance of audio input, please use active sound pick-up. See Figure 3-8.
Audio transmission is similar to video transmission. Try to avoid interference, dry joint, loose contact and it
shall be away from high tension current.
The 4-pin aviation-level port is shown as below. It is to input the audio and video.

Audio Output
The audio output signal parameter is usually over 200mv 1KΩ (BNC). It can directly connect to low
impedance earphone, active sound box or amplifier-drive audio output device.
If the sound box and the pick-up cannot be separated spatially, it is easy to arouse squeaking. In this case
you can adopt the following measures:
Unisight Digital Technologies, Inc.
27
Digital Network Video Surveillance System
Use better sound pick-up with better directing property.
Reduce the volume of the sound box.
Using more sound-absorbing materials in decoration can reduce voice echo and improve acoustics
environment.
Adjust the layout to reduce happening of the squeaking.
Please refer to Figure 3-10. It is for audio and video output.

Alarm Input and Output Connection
There are two alarm input types for you to select: normal open (NO) and normal close (NC).
1. Alarm input
a. Alarm input supports 6V-36V voltage signal alarm input.
b. When the alarm device is connecting one DVR and one other device, please use a relay to separate
them,
Unisight Digital Technologies, Inc.
28
Digital Network Video Surveillance System
2. Alarm output
The alarm output port should not be connected to high power load directly (It shall be less than 1A) to avoid
high current which may result in relay damage. Please use the co contactor to realize the connection
between the alarm output port and the load.
3. How to connect PTZ decoder
a. Ensure the decoder has the same grounding with DVR, otherwise you may not control the PTZ. Shielded
twisted wire is recommended and the shielded layer is used to connect to the grounding.
b. Avoid high voltage. Ensure proper wiring and some thunder protection measures.
c. For too long signal wires, 120Ω should be parallel connected between A, B lines on the far end to reduce
reflection and guarantee the signal quality.
d. “485 A, B” of DVR cannot parallel connect with “485 port” of other device.
e. The voltage between of A,B lines of the decoder should be less than 5v.
4. Please make sure the front-end device has soundly earthed.
Improper grounding may result in chip damage.
