The real-time colour quad is presented as a desktop unit with loop through connections to offer not only a stand alone quad function to display four cameras simultaneously on a CCTV monitor but also to provide an auxiliary display in conjunction with multiplexers or PC based CCTV systems.

The DQ94 will accept up to four non-synchronous video inputs and offers a choice of live displays to suit most applications for 4, 3 or even 2 cameras all with full-screen capacity. The on-screen menu is easy to follow and provides variable alarm alert and auxiliary sequence periods, audible alert on/off, flashing borders (in alarm state) and numeric camera identifier on/off.

The auxiliary (spot monitor) output may be used for either quad or full-screen sequencing display and can be programmed to react in a number of different ways to an alarm alert. Alarm contacts are either all normally open or all normally closed with an alert period of 4 to 120 seconds with an audible alarm alert sounder on/off option.

The quad comes complete with a 12Vdc power supply and is backed up by a non volatile memory which will retain programmed settings on power loss.
