            Procedure


              Note: Cameras are being used in various places in various locations.


           Cameras: CCTV (closed circuit televisions ) is a TV system in which signals are not publicly distributed but are
           monitored, primarily for surveillance and security purposes.
           CCTV uses cases:
           Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern
           CCTV displays can be color, high-resolution displays and can include the ability to zoom in on an image or track
           something (or someone) among their features.
           CCTV is commonly used for a variety of purposes, including:
           •  Maintaining perimeter security in medium- to high-secure areas and installations.

           •  Observing behaviour of incarcerated inmates and potentially dangerous patients in medical facilities.
           •  Traffic monitoring.
           •  Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial
              environments.
           •  Building and grounds security.
           •  Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access
              controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).
           Procedure:
           There are the following points for installations of cameras in different places :-
           Front door
           This is the most obvious route for criminals to gain access into your home, and the biggest proportion  of break-ins
           occur via this entrance. To prevent any items being launched at the delicate CCTV cameras, consider mounting
           the equipment at the second floor level or fitting a wire cage around it.

           Back and side doors
           Any entrance into your property is viewed as a potential channel for a criminal to gain access into your private
           space.  Have  some  cameras  trained  on  all  doors,  as  these  are  your  most  vulnerable  spots. Take  the  same
           protective precautions as described in the previous point, to prevent any tampering.
           Patio and French doors are especially defenceless against break-ins, so support their stability with thick glass
           and a well-placed CCTV camera.
