SECTION 2: INSTALLING THE SYSTEM
2.2.2 Placement
Your monitoring and recording equipment is the core device for constant surveillance and the reliable capture of video evidence.
Observint Technologies strongly suggest that it be installed in a secure location with access limited to authorized personnel.
DVRs and monitors generate heat and should be placed in a clean and well 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 of the DVR that will block airow 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 the DVR and all cameras to ensure normal operation during abnormal power conditions.
Proximity to other cameras and the local LAN
Your DVR connects to cameras through coaxial cables, and to an Ethernet network for remote access. The coaxial cables must be
short enough to provide a good signal level to the DVR from your cameras. Connectorized coaxial cables with a power and audio
leads are usually available in lengths up to 100 ft from your supplier. Ethernet drop cables can be up to 330 ft (100 m) in length. All
cables attach to the backpanel of the DVR (see below). A front panel USB port is also provided for a USB mouse or USB ash memory
device.
