SECTION 2: INSTALLING YOUR SYSTEM
The video and power extension cables have different connectors at each end - one end for the camera drop cable, and the other end
for the DVR and power source. The photo below shows the typical connectors of the camera drop cable with the mating power and

Some extension cables also include a lead with a white connector. This connector is usually used to carry audio signals from a
microphone to the DVR. Cameras with microphones typically include an audio lead in the drop cable.
NOTE
Cable connections are not weatherproof.
2.2 DVR installation
NOTE
Your DVR will not function properly without an HDD. If your DVR was purchased without a HDD, you must have Supercircuits install
the HDD to retain the warranty.
You can install your own HDD, but opening the encloser to install it will void the warranty. Refer to
Appendix C, DVR Compatible
HDDs
, for more information.
2.2.1 DVR placement
Your monitoring and recording equipment is central to constant surveillance and the reliable capture of video evidence. Supercircuits
strongly suggests that it be installed in a secure location with access limited to authorized personnel.
DVRs generate heat and should be placed in a ventilated area. A high temperature environment will reduce the life span and
reliability of the equipment. Additionally, the DVR is not weatherproof, so avoid exposure to liquids and excessive dust. Do not place
objects along the sides or behind the DVR that will block airflow through the unit.
Uninterruptible power supplies
It is strongly suggested that power to the system be routed through an uninterruptible power supply (UPS). These devices will keep
your security system running through most power outages, in addition to providing excellent surge and sag protection. The UPS
should support your video recorder and all cameras to ensure normal operation during abnormal power conditions.
