During the Ignition Shutdown Time:
1. If configured to 0 minutes; the Ignition Shutdown Timer is disabled, and the system
will follow the operation for the Sleep Mode Timer configuration.
2. With Ignition Shutdown Timer enabled, and the system is not recording, all LED
Indicators will turn off, but MicroVu HD will remain fully powered until the Timer
expires. When the timer expires, the system will then follow the operation for the
Sleep Mode Timer (if enabled).
3. During an active record, the unit will continue recording and the system status
indicators will operate normally until the recording ends.
4. If the Ignition Shutdown Timer has not expired, the unit will allow an event record
start from any of the available Event Record Start Triggers. If a recording begins,
the system indicators will operate normally until the recording ends.
5. Once the Ignition Shutdown Timer expires, the system will stop an active recording
and operate according to the Sleep Mode Timer configuration.
6. If the vehicle ignition is turned ON before the timer expires, the Ignition Shutdown
Timer is cancelled and will start over again when the ignition is turned off.
Sleep Mode Timer
When the vehicle ignition goes from ON to OFF the MicroVu HD will first follow the
operation for Ignition Shutdown Timer and then the operation for Sleep Mode Timer
configuration. The Sleep Mode Timer configuration specifies the length of time the
system will remain in a reduced power consumption mode before completely powering
off.
During Sleep Mode:
1. High power devices are put to sleep or shut down.
2. All indicators will be turned off.
3. No Event Record Start Trigger is available when the system is in Sleep Mode.
4. The MicroVu HD will remain in Sleep Mode until the timer expires, then it will
completely power off.
5. If the vehicle ignition switches to the ON position before the Sleep Mode Timer
expires, the system will wake up to the full power state and be ready to record within
a few seconds.
The MicroVu HD will draw a maximum of 291mA of current during Sleep Mode. Typically,
a new or strong vehicle battery will provide enough current to power the MicroVu HD in
Sleep Mode for 5 days without discharging the battery. The vehicle’s battery current
rating, battery age, and other equipment that remains powered on when the vehicle
ignition is off will affect the maximum consecutive days the MicroVu HD should remain in
Sleep Mode. The following table can be used as a general guideline for determining the
Sleep Mode setting; actual results may vary:
Complete Vehicle Power Loss
During an event record, if vehicle power is completely lost to the MicroVu HD
system, the MicroVu HD will switch to the internal battery to end the event record to
prevent data corruption, and then power off after 60 seconds.
