So, How Does it Work?
A surveillance camera can be placed in strategic locations throughout a home or business, and depending on its size, can remain anonymous. Mountable surveillance cameras can be placed in ceilings and on walls, while stand-alones offer more flexibility and can rest on shelves or even bookcases. Ideally, several surveillance cameras, placed independently in various locations, can work together to capture video. Connected to a central system, the surveillance cameras send footage back to a monitor that displays what the cameras see. Unlike traditional television broadcasting, CCTV sends a closed signal to the receiving monitor, allowing viewing to be strictly observed by the connected equipment, only. Surveillance cameras are capable of wide range viewing, so placing them in a corner area of the room will enable them to view a good portion of the room that is unobstructed. Picture quality has become quite impressive, with the monitors receiving video in high resolution, from the surveillance camera’s eye. VCR’s can also be connected to permanently record the transmitted material for future reference. Commonly, coaxial cable ties all of the relevant hardware together, but higher-end systems have incorporated wireless technology that eliminates the need to hide or bury wiring in walls, floors, and ceilings.
