The Nortek DQ94 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.
A video switcher may be connected to either video input allowing the operator to constantly monitor one camera whilst switching through the remaining cameras in the system. An alarm input is provided which, when activated, will cause the alarmed cameras to be presented as the main image.
