Abstract: Devices, systems and methods of reduced-power imaging. For example, a device includes: an imager able to acquire one or more images; a triggering sensor able to sense a triggering event; and a receiver able to receive signals, wherein while the device is in a disarm mode the receiver is operational and the imager and the triggering sensor are not operational.

Abstract: Device, system, and method of rapid image acquisition. For example, a device includes: an imager able to acquire one or more images; a light detector to detect, in response to a triggering event, a light level corresponding to at least a portion of a field-of-view of the imager; a controller to determine based on the detected light level one or more configurational values of the imager, to transfer the determined configurational values to the imager, and to command the imager to rapidly acquire one or more images utilizing the determined configurational values; and a triggering unit to perform an activation process of the apparatus.

Abstract: A system and method including one or more cameras or other sensors to monitor an area, and to transmit such images or sensory data to a local hub that may include a cellular modem. The hub may transmit images or data to a remote cellular handset, where a user may view the images or data, and may transmit a signal back to the hub to take an action in or relating to the area being monitored or relating to the camera or sensor monitoring the area.
