If you ask the experts, they understand
under video surveillance, the answer will be something like this, which is a
procedure that is carried out with the use of opto-electronic devices for
visual monitoring or automated image analysis. And if you ask the ordinary
people who faced the cameras in a bank or a store, then the answer will serve
as an option, it is part of the security object. Both definitions are correct.
Each head has his motive for the
installation of such a system. Someone is for watching customers and employees
in the store, some of the employees of the warehouse, and some of the office
workers to assess productivity. CCTV is used in private homes to control the
children, a nanny or domestic animals. But the main goal - control of the
situation on the observed object in the sample clock or watch.
What the video surveillance is was
described above. But there is a second part of the term - the
"system". What are the elements it is made? Yes, it’s made of DVR, camcorders,
source of power, and enclosures including brackets, monitors, cable, etc.
BTW, you can buy all the video surveillance
device and accessories (e.g. CCTV stand, DC 12V battery) at Banggood for high quality and reasonable prices.
