CCTV (Closed-circuit television) camera is very useful in a fact of life in high profile security facilities, prison and police stations and retail establishments.
A security manager can be monitoring the activities captured on the camera. With CCTV camera they are able to note unauthorized entrance to a facility and monitor behavior that appears suspicious.
The ability to record of CCTV camera is very effective and then it helps for having the images of evidence. If necessary, we also take video footage from the record and separate as evidence for future.
Cost is not much to use of CCTV surveillance. Quality is growing up and instruments price is falling cause of technologies availability. It’s true that quality has a price and you can’t have it except right effort. When you add the lower cost of the cameras with low-cost instruments, after few days it’s become a headache for you because video quality will down, cameras will stop working sometimes you see that everything working fine but your records vanish.
