Wireless transmitter receiver
A wireless monitoring receiver and system use multiple video data feeds from a plurality of cameras. The video feeds are transmitted using a multi-antenna technique, and decoded by a multi-antenna processor. The resulting transmissions are resistant to noise, interference, etc., and can be focused using antenna beams to achieve a simple form of location encryption.
