Please check to make sure the input voltage is correct, and the power button is in the off position when connecting
the power supply.
We recommend you use an Uninterruptible Power Supply (UPS) to guarantee steady operation of the DVR, as well
as to elongate the life span of the DVR and other peripheral equipment such as attached cameras and other
accessories.
3.3.2 Video Input/Output Connections
Video Input Connection Information
The video input interface is BNC.
The input video format includes: PAL/NTSC BNC (1.0VBP- P, B75Ω)
The video signal should comply with your national standards.
The input video signal should have high SNR, low distortion; low interference, natural color and suitable brightness.
To guarantee the stability and reliability of the camera signal, the camera should be installed in a cool, dry place
away from direct sunlight, flammable materials, explosive substances, 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
Please use high quality, well shielded BNC cable. Please select suitable BNC model according to the transmission
distance.
If the distance is too long, you should use twisted pair cable. You can add video compensation DVRs or use optical
fiber to ensure video quality.
You should keep the video signal away from the strong electromagnetic interference, especially power lines.
Keep connection lugs closely contacted.
The signal line and shielded wire should be fixed firmly and in well connection. Avoid dry joint, lap welding, and
oxidation.
