At 420, the method 400 includes determining a user presence based on the received one or more detection signals. For instance, the presence of a user may be determined by nature of (e.g., in response to) receiving the detection signal(s). The presence detection (or attempts thereof) may be repeated continuously or at a predetermined interval (e.g., to ensure a user remains present). Optionally, 420 may include detecting the specific user based on the marker signal. In other words, the signal received from the user-detection assembly may be determined to correspond to the specific user. As described above, the detection of the specific user may include object recognition, identifying a device address, or any other suitable determination that a particular marker corresponding to the specific user is received at 410. The detection at 420 may thus indicate the specific user has engaged the user-detection assembly.
At 430, the method 400 includes directing the camera module to the high-power awake mode from the low-power sleep mode. For instance, 430 may be in response to determining the user presence at 420. Thus, 420 may generally prompt the camera module to change from a mode of limited power draw in which images cannot be capture to another mode of greater power draw in which images can be captured. In other words, additional portions of the image sensor of the camera module may be activated or otherwise be permitted to draw a voltage or current at 430.
At 440, the method 400 includes optionally detecting the door in an open position following or subsequent to 430. Specifically, the door may be detected as being in the open position while the camera module remains in the high-power awake mode. In some embodiments, 440 includes receiving an open signal from the door switch.
