2. WHAT IS …….?
• The word surveillance may be applied to
observation from a distance by means of
electronic equipment (such
as CCTV cameras), or interception of
electronically transmitted information
(such as Internet traffic or phone calls).
It is the monitoring of the
behavior, activities, or other
changing information, usually of
people for the purpose of
influencing, managing, directing, or
protecting

3. WORKING OF VIDEO SURVEILLANCE SYSTEMS :
The first video surveillance
systems were installed by big and
medium-sized business groups to monitor
for shop-lifting and to watch over cash-
handling arenas.
Now-a-days, though, the
majority of homeowners are making use
of video surveillance systems. Home
video surveillance systems permit
householders to keep an eye on specific
regions and keep tabs on thieves and
vandals.
During installation, the
cameras are situated mainly outside the
home in unsafe regions such as entrances,
porches, and where landscaping conceals
access to windows.

4. WORKING OF VIDEO SURVEILLANCE SYSTEMS :
 For a better system, cameras should be located where they are not easily seen.
 They work frequently, passing effigies to the monitor either continuously or at
timed intervals.
 Coaxial cables bind the video surveillance systems simultaneously.
 Available in a variety of sizes from electronics retail merchants, they transfer
the video signal from camera to monitor.
 These cables come along with the surveillance systems, but there are times when
additional wires must be bought for remote cameras.

5. VIDEO SURVEILLANCE SYSTEMS :
There are many types of
video surveillance cameras such as
 CCTV cameras,
 CCTV accessories, and
 video security systems.
CCTV CAMERAS :
It is a collection of video cameras
used for video surveillance.
It is different from broadcast
television as all the equipment is directly
connected together with cables or wireless
transmitters that can not be received by
standard television aerials or equipment.
The transmissions of the video
signals are only intended to be accessible
by the equipment on its dedicated closed
circuit.

6. CCTV CAMERAS :
It is generally used in areas where there
is an increased need for security, such as banks, airports
and town centers. It was initially developed as a means
to increase security for banks but over time it has
developed into a cost effective means of general video
surveillance and home security.
A basic CCTV system comprises of the following;
• Camera, lens and power supply.
• Recording device, VCR or a digital video recorder.
• A monitor.
• Wiring

7.  Some other kinds of cameras comprise dome cameras that can
capture video effigies in a 360-degree angle, bullet cameras, day
night cameras, infrared cameras, which can capture effigies
during night, vandal proof cameras, and hidden cameras.
 Video surveillance has become a major component of business
organizations and police force agencies that make use of these
surveillance cameras extensively.
 The effigies and recordings caught in a video surveillance camera
are permissible in court as proof.
 This makes them crucial for enforcement offices and security
agencies throughout the world.

8. Benefits of video surveillance::
Availability: There was a time when these surveillance techniques were
utilized only in shopping centers and malls. Now-a-days, you can notice closed-
circuit televisions almost any place you visit, from a small store to homes and
holy places. As a result, they guarantee greater public security at a fraction of the
cost.
Real time monitoring: Traditionally, big organizations have always
had the benefits of video surveillance manned by security professionals. In the
past times, the events captured on video were used to expose important
information and work as proof after the event happened. But, modern
technologies let users to check and reply to alarms immediately.

9. Remote access: One of the major advantages of current video surveillance
programs is the reality that they can be accessed from several distant places
through a variety of tools such as a personal computer, PDA or even the cellular
phone.
High quality images: Another significant benefit is the ready availability of
evidential quality video and audio footage. In the unfortunate state where
security has been violated, this evidence turns imperative in finalizing culprits
and gathering data.
When video surveillance becomes a part of the organizational culture,
businesses can understand noteworthy advantages in terms of safety, employee
efficiency and superior bottom lines.
