Transmit data over distances far exceeding that of analog methods and without amplification using a SecurGen video decoder in conjunction with one of SecurGen's 1 or 4 channel video encoders. Link analog cameras to a remote VCR or monitor over a standard network without the need to run specialty cabling. The SecurGen decoder is a robust and versatile solution with the ability to output via either S-Video or BNC, perform 2-way audio transmission to a connected video encoder, and support bidirectional PTZ communication.
