Abstract

A method and system of video surveillance by using existing street light, traffic light and other household or outdoor light assemblies. A video camera is mounted in the light assembly and is powered through power lines of the light assembly. A converter is used to convert images captured by the video camera into Internet Protocol (IP) video data. A combiner then combines the IP video data into the power stream for transmission through the power lines. Both the converter and the combiner are housed in the light assembly. The IP video data travels through the power lines and is separated from the power stream at a collection point. The separated IP video data is transmitted wirelessly or through existing cables over the Internet for viewing.

Claims

1. A video surveillance system using existing street lights, traffic lights and other existing household or outdoor lighting infrastructure, comprising:

a video camera incorporated into an LED array of a traffic signal light, such that the video camera lens is encircled by the LED array, said video camera powered by an electric current that powers the traffic signal light;

the video camera capable of convening videos captured by the video camera into protocols for video data transmission, comprising Internet Protocol (IP), wherein the video camera is powered by power lines of the light assembly; and

the video camera capable of combining the IP video data into a power stream for transmission over the power lines and separating the IP video data from power stream for transmission to one or more viewing locations for surveillance, monitoring and recording purposes.

2. The system of claim 1, wherein the system combines the Internet Protocol video data into power stream within the light assembly.

3. The system of claim 1, wherein the IP video data is separated from the power stream at a collection point.

4. The system of claim 3, wherein the collection point is on or near a lighting structure pole.

5. The system of claim 3, wherein the separated IP video data is boosted, at the collection point, for long distance transmission.

6. The system of claim 3 wherein the IP video data is encrypted at the collection point.

7. The system of claim 3, wherein the collection point receives and collects the IP video data traveling through power stream from a plurality of light assemblies, with the cameras for transmitting, the IF video data to a central base station, thereby reducing, the number of network nodes required to backhaul video data to the central base station, either on the LAN or WAN network.

8. The system of claim 1, wherein signals comprising the IP video data are boosted fear long distance transmission.

9. The system of claim 1, wherein the separated video data is transmitted to existing downstream local-area networks (LAN'"'"'s), wide-area networks (WAN'"'"'s) including the Internet using existing data transmission infrastructure such as data cabling or wireless technology.

10. The system of claim 1 wherein a means for converting videos captured by the camera into IP video data and a means for combining the IP video data into the power stream are housed in the tight assembly.

11. The system of claim 1, wherein the images captured by the camera are processed to offset external tight effects by employing lens filters, including digitally enhancing the images.

12. The system of claim 1, wherein the camera is a video camera having tilt, pan, and zoom capabilities.

14. The system claim 1 further comprising the step of encrypting the IP video data a user viewing station.

15. The system of claim 1 wherein the IP video data is encoded and decoded.

16. The system of claim 1 wherein the IP video data is compressed and decompressed.

13. The system of claim further comprising the step of encrypting the IP video data.
