To protect the vehicle’s battery, the AutoVu™ system shuts down if battery voltage falls below 11V (auto shutdown). The AutoVu™ system does not restart due to a voltage dip caused by engine startup (cranking event protection).

Auto shutdown

To protect the vehicle's battery, AutoVu™ systems include an auto shutdown feature.

If the vehicle engine is off and the AutoVu system is running solely on vehicle battery power, the system will shut down if battery voltage falls below 11V (10.4V detected by the SharpX camera).

Following auto shutdown, the AutoVu system does not start up until it detects a voltage greater than 12V. When the vehicle engine is running again, the voltage typically increases immediately to >12.6V, which allows the AutoVu system to power up again.

Cranking event protection

The AutoVu system does not reboot due to a voltage dip caused by engine startup.

Many law enforcement vehicles include external timers that maintain power to the equipment (radio, etc.) even when the engine is off. If the AutoVu system is being powered with an external timer, and the engine is then turned on, the resulting dip in voltage does not cause the AutoVu system to restart. The system can withstand a temporary voltage dip down to 7V.
