Abstract
A camera system according to an embodiment includes a camera device, a control device, and an application server. The camera device, which includes a camera module and a power line communication (PLC) camera adaptation module, captures and provides audio/video information. The camera device modulates the audio/video information, and provides the modulated information. The camera device also demodulates the modulated signal transferred from a power line to obtain a control signal, and adjusts camera parameters according to the control signal. The control device is connected to the PLC camera adaptation module via the power line. The control device demodulates a received modulated signal of the audio/video information, and provides the demodulated signal. According to a received control indication information, the control device generates a control signal, modulates the control signal, and controls the camera module. The application server stores and provides the audio/video information, camera device information and controlling purview information of the camera device. The application server also generates and provides the control indication information. A method for controlling cam…
