Abstract: A networked camera for controlling electronic devices is provided. The camera includes a camera module for obtaining images, a remote control module for generating remote control signals for electronic devices, and a module for controlling orientation of the remote control module. The remote control module includes an IR (infrared) beam emitter for generating IR remote control signals. In response to a control command from a user device, the camera identifies a target electronic device, an orientation associated with the target electronic device. The camera changes orientation of a remote control module toward the target electronic device using the identified orientation and transmit an IR control signal for controlling the target electronic device.
