Understanding CCTV and Surveillance Cameras
What is CCTV?
CCTV, or Closed Circuit Television, refers to a system of video cameras used for surveillance of crimes. These cameras are commonly found in public places, businesses, and homes to monitor activities and deter crimes. The acronym “closed-circuit” indicates that the video feeds are only available to a specific group of people rather than being publicly transmitted.
CCTV systems provide real-time monitoring as well as recording of video footage for security purposes. This means that not only can someone watch live events happening at a particular location through these cameras, but they can also review past recordings if needed.
Surveillance cameras have become an essential tool in maintaining security and preventing unwanted incidents. They allow authorities to keep an eye on public areas such as parks, streets, airports, train stations, and bus terminals.
How Are CCTV Cameras Used?
In businesses like banks or retail stores, CCTV cameras help prevent theft by monitoring customer activity throughout the day. For example, if a shopkeeper notices something suspicious happening on one of their screens – perhaps someone trying to steal an item – they can quickly respond by contacting security or law enforcement.
Similarly, homeowners often use surveillance cameras around their property to keep tabs on any unusual activity while they’re away from home. Some systems even send alerts directly to the homeowner’s phone when motion is detected within view of the camera lens.
In addition to deterring criminal behavior through constant observation,CCTV systems also play a crucial role in solving crimes after they occur. Law enforcement officials frequently rely on recorded footage from these systems when conducting investigations into unlawful activities that may have taken place within range of the installed cameras.
Working Mechanisms of CCTV Systems
