Open-area Smoke Imaging Detection (OSID) is a reliable and cost-effective smoke detection system for large, open spaces. OSID is comprised of an imager (a camera-like device with a wide field of view) and an emitter on the opposite wall within the protected area. The emitter sends two light signals to the imager. If the light reception is altered and the signature of genuine smoke particles is detected, the imager will go into alarm.
