• This auto-switcher accepts up to 4 standard video inputs from video cameras•4 channel automatic switching• Variable dwell time• Numbered indicator lamps•BNC video connectors • Switches standard 1 Vp-p video Switches automatically in sequence between the cameras. The time each image is on screen (the ‘dwell’ time) is variable via a rotary front panel knob. The front panel also has four switches allowing the user to over-ride the auto-sequencing. Each switch can be switched from its normal ‘auto’ position to either ‘bypass’ or ‘home’. Monitoring for channels switched to ‘bypass’ is skipped. Switching a channel to the ‘home’ position keeps the unit monitoring through that one channel. The unit has two video outputs for maximum flexibility.
