CAMERA SURVEILLANCE

Continuous observation of a place , person, group or ongoing activities in order to gathering information. This is also known as CCTV( closed circuit television) camera.

CAMERA SURVEILLANCE

MAIN PURPOSEIts main purpose is to monitor public or private areas that need to be monitored for security reasons. Modern security cameras use closed-circuit television (CCTV) technology, which employs video cameras that transmit signals to a specific limited set of monitors.

HISTORY

1942 – First CCTV security camera surveillance system installed. German engineer Walter Bruch was responsible for the design and installation of the CCTV security camera surveillance system.•1960’s – First digital camera signals used in cameras over analog by NASA. 1996 – The first IP camera was released in 1996 by Axis Communications.

HOW DO SURVEILLANCE CAMERAS WORK?

CCTV camera systems includes one or more cameras which are used to send video images and audio data to a monitor. Essentially, these camera systems use cameras to transmit the signals to a main hub which then records that data for later viewing or live viewing.

TYPES Surveillance cameras are being installed everywhere for purpose of security and crime prevention and detection. There are many types of surveillance cameras are available for this purpose.

• Indoor camera • Outdoor camera• IR Day/Night Camera• Dome Camera• Etc.

TYPES OF CCTV SYSTEMS

CCTV Systems are broadly divided into two types. These are:

• Wired CCTV System• Wireless CCTV System

WIRED CCTV SYSTEM

Wired CCTV systems connect the camera to the recording device and monitor with the help of standard coaxial cables or Unshielded Twisted Pair(UTP) cables or fiber optic cables. The image data is usually transmitted over a coaxial cable. The signal transmitted over these cables is then fed into a monitor or set of monitors if the image needs to be visible indifferent locations.

WIRELESS CCTV SYSTEM

Basically, Wireless CCTV systems are similar to wired CCTV systems. The difference is that a radio transmitter is attached to the camera. A radio receiver then attached to the input on the monitor system or computer. Wireless systems are useful when the distance between the camera and the monitor is too far to be practical for a cable run.

USES OF CCTV• Maintaining perimeter security in medium-to-high-secure areas and installations.

• Traffic Monitoring

• Building and ground security.

• Overseeing locations that would be hazardous to a human. for example, highly radioactive environment.

• Obtaining a visual record of activities where it is necessary to maintain proper security. for example, in banks, casinos, or airports.

ADVANTAGES It will reduce petty thefts and vandalism in

shops, malls and other public places. The images and videos captured by a CCTV

camera system are often recorded and stored into a database.

In legal cases of thefts and other forms of crime, videos and images provided by the CCTV camera system can serve as a valid proof and evidence against the defaulter.

THE FUTURE OF CCTV CAMERAS

The future of CCTV is – IP CCTV. IP CCTV stands for Internet Protocol – Close Circuit Television. With IP CCTV the video management has become so simple. You can store and retrieve both analog and digitally recorded video footage and access it via an internet connection anywhere in the world. Especially with the growth of Cloud Computing, the IP CCTV has seen a massive boom.
