Abstract

A surveillance system utilizing a mesh network having a large number of surveillance cameras. A plurality of limited range transceivers in direct or indirect communication with one or more of the cameras are located at a large number of nodes and are in communication with other transceivers in the network and are in communication with a control station. In a preferred embodiment most of the nodes are equipped with three transceivers to provide simultaneous communication with one or more camera and at the same time receive and transmit information from other nodes. This system utilizes a routing protocol that was initially developed for wireless voice-over Internet protocol services to large regions. This preferred system incorporates transceiver chips that enable communications over multiple frequencies and communications protocols. The signals from multiple frequencies are then converted into a digital format for routing to central command and control facilities, which can in turn communicate with mobile nodes. The use of multiple frequencies will enable simultaneous communication from multiple inputs without the bandwidth constraints of Wi-Fi systems that are designed for point-to-point Internet access. In addition, the use of a mesh network also enables redundancy to allow reliable communications even when one node or channel fails and enhanced security due to random channel allocation. The surveillance units may be mounted on light poles including street light poles. The also could be incorporated into light fixtures that are in turn mounted on the light poles.

Claims

1. A surveillance system utilizing a mesh network having a large number of surveillance cameras, said surveillance system comprising:

A) at least one control station,

B) a plurality of surveillance units, each unit comprising;

1) a surveillance camera,

2) a plurality of limited range transceivers in direct or indirect communication with one or more of transceivers in other surveillance units or at the at least one control station,

wherein each of said at least one control station and each of said plurality of surveillance units defines a node and

wherein at least a portion of said plurality of surveillance units are equipped with at least three transceivers to provide simultaneous communication with one or more camera and at the same time receive and transmit information from other nodes.

2. The surveillance system as in claim 1 wherein said at least one control station comprises a control unit equipped transceiver chips to provide communications over multiple frequencies and communications protocols.

3. The surveillance system as in claim 2 wherein said control unit is adapted to convert signals from multiple frequencies into digital format for routing to other locations.

4. The surveillance system as in claim 2 wherein said control unit is adapted to provide redundancy to allow reliable communications to provide backup communication when one node or channel fails and to provide enhanced security due to random channel allocation.

5. The surveillance system as in claim 2 wherein at least some of said surveillance units are pole mounted.

6. The surveillance system as in claim 2 wherein at least some of said surveillance units are mounted on a tripod

7. The surveillance system as in claim 5 wherein at least some of said surveillance units are located on outdoor light poles.

8. The surveillance system as in claim 7 wherein said at least some of said surveillance units are part of light fixtures on said outdoor light poles.

9. The surveillance system as in claim 8 wherein said outdoor light poles are street light poles.
