The system video matrix offers a solution to collect and manage images that are able to switch video inputs onto independent outputs with synchronised sequencing among the various monitors. The SM164B matrix is a microprocessor remote-controlled video matrix which allows the video switching of 16 cameras on 4 outputs. In case of alarm, the alarmed video input can be displayed on the video outputs. The alarm contacts are independent and configured as Normally Open (NO) or Normally Closed (NC). The video distributor is used when it is necessary to distribute the same video signals to multiple locations.
