AN IMPORTANT NOTE ABOUT CONVENTIONAL AND
SDI SYSTEMS
Depending upon the model, your DVR is equipped to work with conventional analog cameras
or digital high definition SDI (Serial Digital Interface) cameras. Both cameras use similar
cables and connectors, (see Section 2.5 for connection instructions) but they are not
interchangeable as they are two completely different - and incompatible - technologies. If you
are adding cameras beyond those that came packaged with your DVR, be sure to check that
they are compatible with your system.
Aside from this, the operation of the DVR is identical regardless of the technology. The primary
difference is in resolution. Conventional cameras offer resolutions up to 650 TVL (Television
Lines) as of this writing while Q-See's SDI cameras record in 1080p high definition which is
roughly equivalent to 1000 TVL. Similarly, the conventional DVRs are unable to record in high
definition and the SDI DVRs will only record video at 1080p.
