Functioning of Security Cameras for your home

Signals captured by your security cameras are received by security digital video recorder, compressed and stored in a hard drive of the computer. These can be received either via wireless communication links or by means of a private coaxial cable, which makes them “closed circuit.” The recorded footage can then be retrieved later as a reference to any suspicious activity or mishap.

Placement of security cameras

A security camera can be placed in strategic locations in and around your home or business, and depending on its size, can remain anonymous. Mountable cameras can be placed in ceilings and on walls, while stand-alone offers more flexibility and can rest on shelves or even bookcases. Several security cameras, placed independently in various locations, are ideal for working together to capture video. Security 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.
