When the number of cameras being recorded falls below the expected number of cameras,
MobileView sends an error report to the system log file, and the red LED on the Status
indicator will turn on.
The system will periodically check whether a lost video signal has returned. This action
requires momentarily resetting the video acquisition hardware. The time between resets is
controlled by the
Camera restart dwell time system variable. Setting this value too low will
negatively affect system performance. The default and recommended time period is 60
seconds.
When the ignition or engine run signals end, the DVR enters shutdown mode. The camera
shutdown delay period function is controlled by the Camera shutdown dwell time system
variable ( Figure 41 on page 54). Shutting down camera recording has the benefit of freeing
processor cycles to perform other tasks such as video uploads or scheduled maintenance
activities.
