Closed-circuit television or CCTV, also known as video surveillance is the method through which video cameras transmit signals to specific set of monitors at a specific place. The CCTV signals are not openly transmitted like the broadcast television signals, even though it uses a point to point (P2P) wireless link. The term CCTV is most commonly applied to surveillance cameras used in stores, offices, military facilities etc. Surveillance of the public using such cameras is very common in most parts of the world.
Siemens installed the first CCTV in Germany in the year 1942 for observing the launch of rockets. Walter Bruch the German engineer was responsible for the technological innovation and the design. In the US it began to be commercially used since 1949 and is popularly known as Vericon.
For that reason, a CCTV camera is a fundamental tool that keeps your property secure, along with maintaining the well-fare of your company’s employees and operations. It promotes the safety of the space, reduces crime rates, as well as deters potential smash-and-grabbers from damaging your property. We should have surveillance cameras in public places because they ensure public safety. Rarely will anyone attempt to harm you when they know their actions are being recorded on camera. Cameras keep you and your personal property safe. The police can identify criminals recorded with cameras. Through surveillance cameras, the police can both prevent crimes from happening and can quickly solve criminal cases with material evidence.
In addition, surveillance cameras protect against property theft, and vandalism. If no one is aware of the crime until after it has been committed, the surveillance footage is always a crucial piece of evidence during a police investigation. Criminals are less likely to commit crimes in the area if they know they’re going to be being filmed the whole time. Having cameras in public places make people feel safe. If people know that there are cameras around them, they will most likely not do anything stupid.
