Power-line communication based surveillance system

摘要

A surveillance system configured for communicating with video cameras and other devices connected over a power-line communication network, such as within a residence, or alternatively a commercial building. The system may be manufactured and installed at low cost without the need to route individual cables to each surveillance video camera or device. Bandwidth within the power-line communication network is preferably dynamically allocated to device streams by a server in response to predetermined and event-driven priorities. By way of example, remote communication is supported for allowing remote access to surveillance data and control of the surveillance system. The system may be implemented as a standalone unit or integrated within existing forms of electronics equipment, such as consumer electronics equipment including a television set, a set-top box, or other forms of video-enabled equipment that is adapted for performing power-line network communication.

主权项

1. A method of providing area surveillance, comprising:
capturing video images within a video imaging device and transmitting a video data stream over an AC power-line; encoding said video data stream for transmission over the AC power-line, and dynamically allocating bandwidth of said video data stream over the AC power-line in response to remotely selecting any of multiple modes of the video imaging device; and transmitting said video data stream for receipt by a video display interface device configured for controlling presentation by remotely adjusting bandwidth of said video data stream as passed to the video display interface device for storage or presentation to a user.
