Method and system for remote wireless video surveillance
First Claim
1. A method of providing covert remote wireless video surveillance of a remote location comprising the steps of:
- using a fixed covert imaging means to generate analog electrical signals representative of real time images of the remote location;
using a signal compression chip for converting the analog signals to digital electrical signals and packetizing the digital electrical signals into a secure pre-selected IP protocol format;
transmitting the packetized digital electrical signals using a first transceiver;
receiving the packetized digital electrical signals using a second transceiver;
converting the packetized digital electrical signals into a microwave signal and transmitting the microwave signal to a base unit;
receiving the microwave signal at the base unit;
sending the secure, received signal over a computer network to a plurality of user terminals;
converting the secure, received signal to digital video signals using a video player; and
displaying the digital video signals on the plurality of user terminals for simultaneous viewing by more than one user.

Abstract
Disclosed are a system and method for providing wireless video surveillance of a remote location using microwave transmission of video data using TCP/IP networking protocol. The system comprises a remote unit having one or more analog cameras, a video encoder/decoder linked to a microwave transceiver using Ethernet transceivers connected by a twisted wire pair. The microwave transmission is received by a base unit comprising another microwave transceiver and Ethernet transceiver linked to a computer. The base unit computer is connected to one or more computer networks to enable transmission of the video data to multiple computer terminals on the network.

8. A system for providing convert, direct wireless video surveillance data obtained at a remote location to a plurality of computer terminals on a network comprising:
-
at least one fixed covert camera for generating an electromagnetic signal containing video data representing real time images of the remote location; a signal compression chip for converting the electromagnetic signal into a digital signal; means for encrypting the digital signal into a secure pre-selected IP protocol format; a first transceiver for transmitting the encrypted digital signal; a second transceiver for receiving the encrypted digital signal; means for transmitting via microwave transmissions the encrypted digital signal to a base unit; means for receiving and decoding the microwave transmission at the base unit; and means for transmitting the microwave transmission from the base unit to a plurality of computer terminals over a private network for more than one user to simultaneously view the real time image using the plurality of computer terminals. - View Dependent Claims (9, 10, 16, 17)

11. A covert wireless data communication system for the acquisition and secure transmission of data, comprising:
-
at least one fixed remote transceiver, said transceiver being a self contained, powered device selectively activatable to acquire and transmit, in real time, covert data relating to a geographic location at which the transceiver is placed, said transceiver comprising an imaging means, data encoding means, and a transmitter such that as the imaging means acquires data, the data encoding means converts the data, using a signal compression chip, to a secure digital file which the transmitter transmits at a pre-selected microwave frequency over a secure transmission path; a central transceiver in direct communication with said remote transceiver and receiving the transmitted secure digital file, the central transceiver including a server to which the central transceiver provides the secure digital file when it is received, the server being configured to construct a digital video signal from the data contents of the digital file; and display means to which the resulting digital video signal is supplied for displaying a video image of the geographic location to a plurality of terminals so the real time video image can be simultaneously viewed by more than one user. - View Dependent Claims (12, 13, 14)
