No. It is basically a "smart switch" that monitors the battery for run down. It shuts off the camera when the car battery is discharged to a certain level. That is why I went with the Cellink. IMO a much better solution for BMW's. Camera runs off the Cellink battery first, then it will switch to car battery when the bat pack is depleted and will also turn itself off if the car battery goes below a certain level. The bat pack recharges while you drive or you can charge at home . About an hour to fully charge and lasts 72 hours in parking mode running in dual setup with the BV 650. If you want more standby you can daisy chain cellinks. I have mine installed in the trunk out of the way.
