HD Video Quad Display System with High Definition DVI/HDMI Output

*** Unfortunately product now unavailable due to component obsolescence.*** 

Specifically designed for video surveillance monitoring applications, FourSight-DVI allows up to four PAL or NTSC cameras to be viewed on one high resolution LCD display with outstanding clarity. 

Traditional video quads have to reduce the resolution of each input to show more than one camera per screen. FourSight-DVI takes advantage of high-resolution computer and TV LCD displays to show 4 standard definition cameras on the one screen without any loss in quality.

FourSight DVI consists of 4 standard-definition PAL or NTSC inputs which are processed together into to one high-resolution DVI (or HDMI) output. By default, all 4 video inputs are shown as a quad with a further 4 modes displaying different combinations of the 4 inputs on the output screen. FourSight-DVI automatically configures itself for operation with most high-resolution monitors and supports most resolutions from 1024 x 768 pixels to 1920 x 1080 (1080/P). 

For OEM applications, the system may be supplied as a unit or PCB, together with full support for interfacing via the product’s external control protocol.
