Video surveillance is the use of security cameras to monitor and record activity in a specific area or location for security, safety or monitoring purposes. Security cameras capture live footage, which can be viewed in real-time or recorded for later review. Video surveillance is also referred to as CCTV.
CCTV cameras will transmit their footage through wired or wireless data networks straight to a monitor either locally or in a distant location. Video surveillance, on the other hand, makes use of a fast ethernet connection to transmit footage where it can then be stored for later access.
Surveillance technology is used to monitor individuals' digital and physical actions and communications. Common forms include data-gathering apps on smartphones, and facial recognition software in smart security camera systems.
Surveillance is used by citizens for protecting their neighborhoods. And by governments for intelligence gathering - including espionage, prevention of crime, the protection of a process, person, group or object, or the investigation of crime.
