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
BTTTB
The signal line and shielded wire should be fixed firmly and in well connection. Avoid dry
joint, lap welding and oxidation.

output, a VGA output and a
HDMI output.
System supports BNC, VGA and HDMI output at the same time.
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.

Connecting Audio Input & Output, Bidirectional Audio
3.6.1 Audio Input
BNC port is adopted for audio input port.
Due to high impedance of audio input, please use active sound pick-up.
Audio transmission is similar to video transmission. Try to avoid interference, dry joint,
loose contact and it shall be away from high tension current.
