Operation control of battery-powered devices

A method of controlling operation of at least one battery-powered device positioned at a remote location from a camera, the method comprising:

• receiving, by a power control system, a pan angle, and a tilt angle of the camera, wherein the pan angle and the tilt angle are indicative of a field of view of the camera;
• retrieving, by the power control system, a position of the at least one battery-powered device, wherein the position of the at least one battery-powered device is predefined;
• comparing, by the power control system, the pan angle, and the tilt angle with the position of the at least one battery-powered device;
• determining, by the power control system, whether the at least one battery-powered device is positioned within the field of view of the camera, based on the comparison;
• and
• transmitting, by the power control system, instructions for activating at least one of a functional mode and a sleep mode of the at least one battery-powered device to control power consumption of the at least one battery-powered device, based on the determination, wherein an instruction to activate the sleep mode of the at least one battery-powered device is transmitted when the at least one battery-powered device is not positioned within the field of view of the camera, wherein the at least one battery-powered device consumes less power in the sleep mode than in the functional mode, and wherein an instruction to activate the functional mode of the at least one battery-powered device is transmitted when the at least one battery-powered device is positioned within the field of view of the camera, wherein the at least one battery-powered device consumes more power in the functional mode than in the sleep mode.

A camera having a predefined field of view for recording activities occurring within the field of view, the camera comprising:

• a first detection unit configured to detect a pan angle and a tilt angle of the camera while recording the activities, wherein the pan angle and the tilt angle are indicative of the field of view;
• and
• a power control system for controlling operation of a first battery-powered device positioned at a remote location from the camera, the power control system comprising:
• a receiving module configured to receive at least one of a pan angle and a tilt angle of the camera, wherein the pan angle and the tilt angle are indicative of a field of view of the camera;
• a retrieving module configured to retrieve a position of the first battery-powered device, wherein the position of the first battery-powered device is predefined;
• a comparison module, in communication with the receiving module and the retrieving module, configured to:
• compare the pan angle and the tilt angle with the position of the first battery-powered device;
• and
• determine whether the first battery-powered device is positioned within the field of view of the camera, based on the comparison;
• and
• a transmission module, in communication with the comparison module, configured to transmit instructions for activating at least one of a functional mode and a sleep mode of the first battery-powered device to control power consumption of the first battery-powered device, based on the determination, wherein the transmission module is configured to transmit an instruction to activate the sleep mode of the first battery-powered device, when the first battery-powered device is not positioned within the field of view of the camera, wherein the first battery-powered device consumes less power in the sleep mode than in the functional mode, and wherein the transmission module is configured to transmit an instruction to activate the functional mode of the first battery-powered device, when the first battery-powered device is positioned within the field of view of the camera, wherein the first battery-powered device consumes more power in the functional mode than in the sleep mode.
