Surveillance cameras, also known as CCTV cameras, are used to continuously monitor public or private areas for security purposes. Modern surveillance cameras transmit video signals to specific monitors. There are different types of cameras for indoor and outdoor use, including dome, bullet, and hidden cameras. CCTV systems can be wired or wireless. Surveillance cameras are commonly used to maintain security in buildings and facilities, monitor traffic and behavior, and obtain visual records for evidence. While they can deter crime, surveillance cameras have disadvantages like privacy concerns and not being able to monitor all areas at all times. The future of CCTV is moving to IP cameras that allow video to be accessed anywhere via the internet.

3. 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.

5. 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.

6. 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.

7. 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.

8. 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.

16. TYPES OF CCTV SYSTEMS
 CCTV Systems are broadly divided into two types. These are:
• Wired CCTV System
• Wireless CCTV System

17. 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.

19. 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.

21. 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.

22. 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.

23. 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.

24. 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.
