Abstract: An example security sensor includes a battery power supply, camera coupled to the battery power supply to receive power, activity sensor, processor, and microcontroller. The processor is placed in a sleep state and is wakeable to an awake state. The processor coupled to the battery power supply, and coupled to the camera to receive and process image data including images of an activity within a zone. The microcontroller is coupled to the battery power supply, coupled to the activity sensor to receive interrupts responsive to detection by the activity sensor of the activity within the zone proximate the security sensor, coupled to the processor to send and receive data, and, responsive to receiving a first interrupt from the activity sensor, place the processor in an awake state to signal the camera to capture a set of images and to receive and process the image data including the set of images.

Abstract: By way of example, a low-power processing device is disclosed. The low-power processing device includes a battery power supply, a processor, and a micro-controller. The processor sleeps by reducing voltage to a non-transitory memory of the processor and storing system settings in a non-transitory memory of the microcontroller, which is coupled to the processor via a communications bus. The processor is further coupled to the battery power supply to receive power. The microcontroller is coupled to the processor via the communications bus to send and receive data. The microcontroller sends an interrupt (A) to the processor and the processor receives A and wakes up by polling the microprocessor for an event associated with A and loads the system settings via the communications bus from the non-transitory memory of the microcontroller into the non-transitory memory of the processor.
