Matrix SM84A and SM164A are products for professional use in applications for security and surveillance and
dedicated to the management of video signals. The SM84A and SM164A models differ only in the number of
possible video input connections, 8 and 16 respectively; there are four video outputs, one of which can be
managed directly by a VCR.
As well as the usual switching, alarm management and on screen menu programming operations, the SM84A
and SM164A matrix is equipped with an optional auxiliary line that can be used to control the telemetry or
multiplexer units. Refer to the matrix manual for further information on this subject.
