Video surveillance systems capture activities that require analysis and with the mass proliferation of cameras, there is a corresponding increase in demands on manpower to monitor and analyse images. Video Analytics provides a means using software algorithms to take away an element of manpower and human errors.
The software can either reside on a server which receives the images for analysis or on the camera itself. Camera based systems can be linked to decision algorithms which can determine whether to stream video content to a control room or recorder based on the events under analysis.
The simplest form of video analytics is Video Motion Detection, an established technology that can be prone to errors and false alarms unless triggers or thresholds are set to filter out erroneous motion that is of no interest to the operator. Other Video Analytics software can be used for virtual trip wiresŁ for the protection of perimeters and zones, abandoned object or missing object detection, people counting and behaviour analysis.
Intelligent analysis is based on Artificial Intelligence and is used for more complex analysis involving object recognition, directional analysis and behavioural analysis. These systems tend to analyse and compare data rather than images which is useful for forensic analysis of video content when the alternative is to examine large quantities of video film.

Human Recognition Systems is working with Newcastle Airport on an innovative exit lane system enabling fast passenger exit whilst monitoring behavioural patterns and flow to recognise abandoned objects and people moving against the flow
Report from ADT shows that overall levels of retail shrinkage are increasing with the proportion of crimes committed by retail employees reducing as technology improves and potential thieves become more likely to be deterred
Simple directional movement detection could have alerted security to unauthorized use of exits and analysis of existing video footage could have determined if the Newark airport suspect had been screened, preventing the necessity to re-screen the entire departure area
