The switch recieves a video signal from four sources and it sends one to one or both of the available outputs. The selection of the source can be manual or automatic. In an automatic mode the time interval of switching from one source to another is from 0.5 sec to about 125 sec (0.5 sec increments). The pre-arranged switching time can be set for each camera individually or for all cameras simultaneously.

Source inputs that are not being used can be easily excluded from the sequence. The device is internal and it is intended to work continuously. It works in all formats and with both B/W and colour cameras. The two output ports (a single port splitter) can be used for two monitors or a monitor and VCR.
