Surveillance
In simple words, Surveillance is monitoring of behavior, activities, or other changing information for the purpose of influencing, managing, directing, or protecting people. This can include observation from a distance by means of electronic equipment such as CCTV or interception of electronically transmitted information. It can also include simple no- or relatively low-technology methods such as human intelligence agents and postal interception. Surveillance cameras are video cameras used for the purpose of observing an area. They are often connected to a recording device or IP network, and may be watched by a security guard or law enforcement officer.
Surveillance is used by governments for intelligence gathering, prevention of crime, the protection of a process, person, group or object, or the investigation of crime. It is also used by criminal organisations to plan and commit crimes, such as robbery and kidnapping, by businesses to gather intelligence, and private investigators.

Surveillance cameras has so much power that the entire crime seen can be captured in it and the criminals can be caught in no time. It is very important for places like supermarkets and malls to have surveillance cameras because many stealing can occur mainly in these type of places. But have surveillance cameras outside the house covering the footage of the front and the backyard of the houses can be necessary at times to in order for the house owners to be alert of robbers or dog thieves like shown in the video above.

So as we can see surveillance camera played a vital role in the above video. The entire murder has been caught in the camera which makes it easier for the police to catch the criminals and give them the punishment they deserve. Surveillance cameras thoroughly act as the form of protection and main reason why people use them is to protect themselves from any crime or even if the crime is already committed, they will at least be able to get justice with the help of proof present in the surveillance cameras.
