Patent ID: 7035313

Claim:
A video surveillance system, comprising: (a) a first video surveillance camera adapted to generate a first analog composite video signal including frame synchronization pulses and line synchronization pulses; (b) a first frequency-hopped spread spectrum transmitter having a programmable processor, memory, and an input circuit connected to said first video surveillance camera and adapted to sense said first analog composite video signal including said frame synchronization pulses and said line synchronization pulses; (c) said first frequency-hopped spread spectrum transmitter being programmed to select a first hop tuning frequency from a plurality of pre-assigned selected frequency band hop frequencies stored in said transmitter memory; (d) said first frequency-hopped spread spectrum transmitter having a first tunable oscillator tunable to any of said plurality of pre-assigned selected frequency band frequencies; (e) said first frequency-hopped spread spectrum transmitter input circuit being configured to detect said first analog composite video signal frame synchronization pulses, (f) said first frequency-hopped spread spectrum transmitter being programmed to synchronize transmitter frequency hop timing in response to detection of said first analog composite video signal frame synchronization pulses and modulate said first analog composite video signal including said first analog composite video signal frame synchronization pulses and said line synchronization pulses onto a carrier at said first selected hop frequency for a selected hop frequency dwell time; and (g) a frequency-hopped spread spectrum receiver programmed to demodulate said modulated first analog composite video signal including said frame synchronization pulses and said line synchronization pulses at said first transmitter first selected hop frequency and generate a first baseband composite analog video signal in response thereto.
