Security Cameras
Security camera systems, popularly referred to as
the CCTV cameras, are extremely popular today.
Security cameras have made our world much more
safe and secure that it was ever before.
Apartments, private homes, offices, shops,
government buildings, roads and railways,
security cameras are used everywhere. These
cameras have helped prevent many mishaps,
robberies, murders, rapes and thefts. Many
criminals have been convicted with the help of
these camera recordings as evidence. With such
great advantages, the popularity of these
security cameras has grown immensely.

Security cameras may use the CMOS or CCD
technologies. The former technology is cheaper
and generates poor quality images and has poor
light sensitivity. When there is a genuine threat
to security, it is best to install cameras with
CCD technology since that yields good quality
image even in poor light conditions. The price of
security cameras rises with the quality of image
produced by the camera. Bullet cameras are one of
the most popular types of security camera.

Security cameras may be fitted with infrared LED
devices that allow visualisation of dark spaces.
This technology understandably cost a lot and
hence is still out of reach of common public.
Professional grade security cameras come in box
type casings which may be weatherproof if
installed outdoors. These cameras can be fitted
with a variety of lenses to visualise objects at
different distances.
