3.2.2 DVR placement
Your monitoring and recording equipment is central to constant surveillance and the reliable capture of video evidence. SCD 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 airow through the unit.
