Electronic surveillance system
First Claim
1. A surveillance system for remotely monitoring an area, comprising:
- a plurality of selectively controllable sensors located at predetermined positions proximate the area being monitored, each sensor comprising at least one video camera and a plurality of microphones and generating an output electrical signal, with one of said microphones being arranged to provide a noise free signal;
a plurality of integral modules electrically connected to the sensors, each integral module comprising a first antenna for transmitting the output signal from a selected one of the sensors, a second antenna for receiving encrypted command signals, means for decrypting the command signals and for selectively operating the sensors;
first power means for supplying electrical power to the plurality of sensors and the plurality of integral modules;
command and control means for remotely activating and selecting the integral modules and the sensors, comprising a command encrypter for generating the encrypted command signals, a third antenna for receiving the output signal transmitted by the integral modules, a fourth antenna for transmitting the encrypted command signals to the integral modules, means for displaying and reproducing the output signal received by the third antenna, and means for recording the output signal received by the third antenna; and
second power means for supplying electrical power to the command and control means.

Abstract
The present invention is a "tethered remote" surveillance system that uses a command and control transmitter/receiver to activate selectively a number of audio and video sensors. The system generally comprises a plurality of remote sensors which are selectively controllable through a plurality of remote integral modules to which the sensors are connected. Each integral module is a physically compact unit which includes an antenna for transmitting the outputs of the plural sensors to a command and control station and an antenna for receiving encrypted command signals from the command station. The command station includes an encrypter for generating the command signals, an antenna for transmitting the signals to the integral modules and an antenna for receiving the signals transmitted by the integral modules, as well as devices for displaying and recording the signals received.
