micro-FourSight Ultra Compact Video Quad Display System

Micro-FourSight is an ultra compact quad, specifically designed for surveillance monitoring applications and allows up to four cameras to be viewed on one screen.

Unlike most quads, Micro-FourSight is very compact, lightweight and power efficient.
Micro-FourSight’s advanced digital video processing provides full control of each picture’s size and position together with picture cropping and overlay. For ease of use the system includes 16 pre-set display modes, which can be reconfigured via its USB/RS232 control ports and optional PC configuration utility. micro-FourSight provides excellent picture quality coupled with real-time update rate per channel.


Camera ident plus date and time are shown onscreen, which again are fully configurable via the control ports

Micro-FourSight will operate with almost any video source, automatically configuring itself for PAL or NTSC operation. For OEM applications, the system may be supplied as a unit or PCB, together with full support for interfacing to the product’s USB / serial control protocol.
