Connecting Power Supply

We recommend you use UPS (uninterrupted power supply) to guarantee steady operation, combo DVR life span,
and other peripheral equipment's operation such as cameras. We also strongly recommend that you plug the DVR
and cameras into a transient voltage surge protector (UL-1449 rating). Look for a clamping voltage of 330 or lower,
Joule rating of at least 400, and a response time of 10 nanoseconds or less.

3.5.1 Connecting Video Input

The video input interface is BNC. The input video formats include: PAL/NTSC (See Figure 3-2)
The video signal complies with North American NTSC video standards.
We recommend setting your video up in an area with low video input signal distortion and interference in an area
with suitable lighting.
Ensure the stability and reliability of camera signal:
The camera should be positioned so that direct sunlight does not shine into it, and away from flammable, explosive
substances. Cameras and DVR should share the same grounding if possible to ensure normal operation of
cameras.
Ensure stability and reliability of the cables
If you are running cables more than 200 feet or installing cable in walls, we recommend using high quality shielded
RG59 cables. If you plan on running cables over 800 feet, we recommend using a higher quality shielded cable
such as RG6.
For distances above 1,800 feet, we recommend using fiber optic cable to ensure video quality.
Keep the video signal away from any strong electromagnetic interference.
Make sure cables are well connected to DVR
The cable should be fixed firmly to the BNC connectors on the dongle.

3.5.2 Connecting Video Output

BNC (PAL/NTSC BNC（1.0VP- P， 75Ω）output and HDMI output.
Video output includes
System supports BNC and HDMI output at the same time. (See Figure 3-3)

When hooking your system up to a PC monitor through the BNC video out port you will need to use a
composite to VGA converter box. We do not recommend attaching to RCA ports on a TV through the BNC
output because it can damage the TV, DVR, or both.
