video encryption modules sometimes encryption is also called VIDEO SCRAMBLER, or VIDEO PRIVACY. The encryption modules are very small, maybe 50 x 40 x 10mm, and they consist of an ENCODER at the transmitter, and a DECODER at the receiver, to prevent unauthorised persons spying on the video transmission. If other persons monitor the video signal with a scanner or receiver ( example - 2.4GHz), they only see horozontal lines, no picture. contact:sylvia686_lee#hotmail.com Show More
