Do you want to monitor your shop or house 24X7 from burglars or thieves? Or you are a security
in-charge of a huge building complex or shopping complex that has to safeguard the entire
structure? In either case, you can use security cameras or more popularly known as CCTV
cameras to keep an eye on a particular area. A CCTV camera is nothing but a video camera which
continuously feeds signal to a specific monitor or place. So, with the help of a camera and a
monitor, one can continuously have a watch over one place. The security cameras are mostly used
for surveillance of high risk areas such as banks, airports, military places, casinos, shopping
complexes and departmental stores. They are more useful in places where a large number of
people gather on a day-to day occasion.
Security cameras have evolved over the years with the latest technology being used for more
efficiency and security. Cameras use technology such as IP (internet protocol) for sending
information directly over networks in digital form. Then there are networking cameras which daily
provides feeds from private and government agencies to contribute footage. These cameras
installed in public schools, subways, trains, buses and even in some houses are used in
emergency situations to provide real-time video. Now, the most important use of these cameras is
providing security against crime. Security cameras have provided the police with many video
evident of crimes such as burglary, murders and kidnapping. Also, they are used to control traffic
by sending the real-time videos to operators who control the traffic signals.
Apart from the above benefits of the security cameras, they are mostly used by industries to
monitor areas where constant human intervention is not possible. Processes in nuclear fuel,
various reactors and chemical industries require regular checking of temperature and other
conditions which are carried out with the help of these cameras. Also, these cameras are of great
use in retail or departmental shops where large people gather every day for shopping. It is not
possible to have a look at each and every person in the store at the same time; hence these
security backup cameras are a great way of reducing the illegal shop lifting.
With all these advantages, these cameras have also been proven to be a disadvantage at many
situations. If these cameras are not monitored properly, the feeds or signals can be used by wrong
people. Also, there have been many outrages about the security backup camera destroying
privacy of people. But, these disadvantages cannot minimize the huge benefits they provide.
