Cameras should be mounted high and away from interferences so they can overlook the area of protection.  The
camerashouldbemountedsothatlargesourcesoflight(glasswalls,largebaydoors,ordirectionalspotlights)willnot
compromisetheimagequalitybysaturatingtheimagesensorwithlight.Ideally,theFOVwillincludeboththeceiling

The most significant factor affecting system performance is the camera positioning and the resulting FOV.  It is
importanttopositioncamerastomaximizetheFOVaswellastheareacoveredbythecameras.Aperformancebased
designshouldbeusedtodeterminethenumberofcamerasneededtoproperlycoverthespacefromthedetermined
firethreat.Table1showstheresponsetimestovariousfiresources.Camerasshouldbeplacedhighinthespacesoas
