Application

Applications:

Crime management

CCTV surveillance can deter potential criminals. When a crime does occur, video footage can help law enforcement to investigate and later provide evidence for the prosecution in a law court. Used in conjunction with CCTV, audio, thermal and other types of sensors can alert officials to occurrences that are out of the ordinary, e.g. fire or gunshots at a location. For businesses, CCTV cameras can detect and monitor in-house criminal activities. Security cameras are able to monitor areas that are not easily accessible, e.g. rooftops.

Disaster management

Using CCTV cameras, emergency services and rescue workers are able to assess and monitor events in real-time to relay a “situation” via video to disaster management teams, e.g. from inside a burning building, from a cave, or from a helicopter flying over a scene.

City and community street monitoring

Cameras at traffic lights and elsewhere in cities monitor people to gather traffic statistics as well as evidentiary footage for speeding.

Medical monitoring and diagnosis

There are about 43 facial muscles that express people’s thoughts and feelings. Smart software can identify these expressions, e.g. pain or anxiety, from images more easily than people can. CCTV cameras can also monitor patients – for instance, children or the elderly – to identify potential medical crises, e.g. a stroke, or an epileptic or asthma attack.

Behavioral research

CCTV used to research suicide found that 83 percent of people attempting to throw themselves in front of a train showed specific behaviors. These were later analyzed from CCTV footage and are now used to alert monitor watchers to potential suicides. Surveillance networks are also used by researchers to record crowd activities in public places and prevent anti-social behaviors. For instance, cameras have been used at schools for security, and to record bullying or playground incidents on video.

Retail intelligence

Market intelligence garnered from video surveillance of customers is being used to analyze buying trends and enable enhanced strategizing, e.g. how to do people shop, which aisles do they traverse the most, how likely are they to respond to calls to action within different store layouts. Heat maps can show the highs and lows of shopper traffic at specific locations in a store, helping stores to identify peak buying times, preferred promotion types, and staffing requirements for peak shopping periods.
