About HD-SDI
HD-SDI is a standard for transmitting un-compressed, high definition video along
high-grade coaxial cables (such as RG59). It uses digital signals that carry large amounts
of information (over 1Gbit/second).
Because HD-SDI video systems use digital signals, they are incompatible with traditional
cameras and DVRs, which transmit video using analog signals, that are commonly used in
video surveillance applications. This means that you cannot use non-HD-SDI security
cameras with an HD-SDI DVR, and you cannot use HD-SDI cameras with a non-HD-SDI
DVR.
Installation Warnings
• Use the included extension cables or visit
extension cables.
• The extension cable must be a single stretch of cable between the DVR and camera. You
cannot connect multiple extension cables to each other.
• You cannot mix 1080p and 720p HD-SDI cameras. All cameras connected to the system must
be either 1080p or 720p.
Installation Tips
• Mount the camera where the lens is away from direct and intense sunlight.
• Plan your cable wiring so that it does not interfere with power lines or telephone lines.
• Ensure that the camera wiring is not exposed or easily cut.
• Mount the camera in an area that is visible, but out of reach.
• Avoid pointing the camera at a glass window to see outside, as this may result in a poor image
caused by glare from indoor / outdoor lighting conditions.
• Adjust the camera angle so that it covers an area with high traffic.
• In "high-risk" locations, have multiple cameras point in the same area. This provides camera
redundancy if a vandal attempts to damage the camera.
Installing Cameras
Test the cameras before permanent installation. Plan where you will route the wiring for
the camera and where you will aim the camera.
To install cameras:
1
Mount the camera(s) to the desired mounting surface according to the instructions that came
with the camera(s). Choose a firm mounting surface.
NOTE: If you wish to mount cameras to drywall, it is recommended to use drywall plugs (not
included).
