The WatchIN™ Industrial Grade 3 Detector provides superior catch performance and immunity to false alarms, especially in extremely harsh environments such as production areas containing operating machinery, construction sites, shipyards and hangars.

WatchIN™ includes RISCO Group’s most advanced detection technologies including Anti-Cloak™ Technology, Sway Recognition Technology, Active Infrared for Anti-mask, GreenLine Technology and RISCO Bus Technology. WatchIN is designed to meet PD6662, EN 50131-1 and EN50131-2-4 Grade 3, Environmental Class III.

WatchIN™ can be installed on the RISCO Bus, dramatically reducing cabling, installation equipment and labor costs, while providing the benefits of remote services.
