Abstract
A computer includes a processor and a memory storing instructions executable by the processor to instruct a first sensor to run at a scanning rate; in response to a trigger event, reduce the scanning rate; in response to receiving data from the first sensor indicating a newly present object, turn on a second sensor; and then record data from the second sensor. The second sensor has a higher power draw than the first sensor.
