IndigoVision's SMS4 release 3 starts with the qualification of incoming data to filter out false alerts so personnel can focus on likely threats. The system also lets you embed prior intelligence by noting the sequence and combination of events that may constitute a situation. Qualified alerts that are not assessed within a certain time period are then automatically passed along a chain of operators, accompanied by real time contextual video, to guarantee a swift response. Events that are identified as priority get automatically escalated to higher levels of authority and/or agencies in other locations.
