Abstract: A method including, at a camera, detecting motion in a field of view of the camera using a motion sensor, initiating processing of video data corresponding to the field of view in which the motion was detected, ceasing the processing after a first time duration, and determining a cool-off period for the motion sensor, the cool-off period having a second time duration based on the first time duration during which the camera does not detect motion using the motion sensor.

Abstract: Methods of the disclosed subject matter provide compensation for sensor drift in a hazard detection device having a plurality of sensors coupled to a processor to determine that a carbon monoxide sensor is drifting and to compensate for the drift by calculating a corrected carbon monoxide measurement value based on the ambient environmental conditions.
