Under some circumstances, the input AC voltage is substantially low and insufficient to support some camera functions that require relatively large power consumption. Optionally, the camera module 1004 is configured to in accordance with a determination that the input AC voltage is not greater than the supply threshold, disable capturing images and exchanging data with a remote server, and enable communication with a client device via a short range communication link e. g. , a Bluetooth communication link. Optionally, the camera module 1004 is configured to in accordance with a determination that the input AC voltage is not greater than the supply threshold, activate a low power mode. In the low power mode, the images are optionally captured and/or transmitted to the server at a lower resolution and a lower frame rate, and local image processing may be disabled to conserver power.
