SURVEILLANCE CAMERA

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.

SURVEILLANCE CAMERA

MAIN PURPOSE

A surveillance camera is used in surveillance 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.• 1956 –

First VCR produced by Ampex Corporation team led by Charles

Ginsburg. 19 year old engineer Ray Dolby was also part of the team.

Built for commercial business use.• 1960’s – First digital camera

signals used in cameras over analog by NASA.• 1972 – First VCR for

home use produced by Philips.• 1996 – The first IP camera was

released in 1996 by Axis Communications.• 1998 – First consumer

digital video recorders (DVR) released to the public.

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 if you have full time security

personnel on your premises.

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.

OUTDOOR CAMERA

IR DAY/NIGHT CAMERA

DOME CAMERA

BULLET CAMERA

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

CCTV is commonly used for a variety of purposes, including:

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

• Observing behavior of incarcerated inmates and potentially dangerous patients

in medical facilities.

• 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

• Deters Crime: The presence of CCTV camera system for surveillance will reduce

petty thefts and vandalism in shops, malls and other public places.

• Helps Maintain Records: The images and videos captured by a CCTV camera

system are often recorded and stored into a database.

• Protects Employees: This is particularly helpful in customer service centers. The

employees providing customer service may sometimes be subjected to verbal abuse

or physical attacks. CCTV camera system helps to identify such instances and act

immediately. It is also helpful to keep a tab on the activities of the employees.

• For Evidence in Lawsuits: 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.

DISADVANTAGES

• Do Not Work Always: CCTV camera system cannot monitor every area of

your office or home at all times. Hence it cannot be considered as a

foolproof method for crime prevention.

• Privacy Concerns: Invasion of privacy is the major issue when it comes

to any security system device like the CCTV camera system. It lowers the

employee morale and hampers productivity at times. Constant monitoring

of every activity might put the workers ill at ease.

• Initial Costs: The initial costs incurred per camera are high. The

installation may also increase the initial expenditure. It depends upon the

complexity of the CCTV camera system as well.

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.
