WHAT IS CCTV
Surveillance cameras on a corner
Dome CCTV cameras

• Closed-circuit television (CCTV) is the use
  of video cameras to transmit a signal to a
  specific place, on a limited set of monitors.
• It differs from broadcast television in that the
  signal is not openly transmitted, though it may
  employ point to point (P2P), point to multipoint,
  or mesh wireless links. Though almost all video
  cameras fit this definition, the term is most
  often applied to those used for surveillance in
  areas that may need monitoring such as banks,
  casinos, airports, military installations, and
  convenience stores.

In industrial plants, CCTV equipment may be used
to observe parts of a process from a central
control room, for example when the environment is
not suitable for humans. CCTV systems may operate
continuously or only as required to monitor a
particular event. A more advanced form of CCTV,
utilizing Digital Video Recorders (DVRs),
provides recording for possibly many years, with
a variety of quality and performance options and
extra features (such as motion-detection and
email alerts). More recently, decentralized
IP-based CCTV cameras, some equipped with
megapixel sensors, support recording directly
to network-attached storage devices, or internal
flash for completely stand-alone operation.

CCTV Cameras CCTV systems have become extremely
popular over the last few decades as the
technology has improved and become more
affordable. The majority of CCTV cameras in use
today are usually for surveillance and security
purposes. CCTV systems can be found in almost
every bank, casino, mall, and large department
store. In fact, CCTV systems have become so
affordable, most smaller mom and pop stores also
have CCTV systems in them for security purposes.
8
TYPE OF CCTV
There are many types of CCTV cameras. They can be
categorized by the types of images they are able
to capture, the amount of frames they can take
per minute, the type of connection to the monitor
or video recording device, whether they are able
to move position, and special functions they can
provide. Types of Images CCTV cameras generally
take both black and white or color video images.
In addition, many CCTV cameras even have night
vision capabilities that allow a CCTV camera to
view and record low light images using special
technology. Frames per Second Frames per second
is the amount of full frames that a video camera
captures and sends to a recording device or
monitor per second. While most CCTV camera
systems easily capture 30 or more frames per
second, the amount of video tape or digital
storage would be enormous to record every moment
of everyday. For most stores, speeds of 1 to 6
frames per second are more than enough to catch
and record a perpetrator committing a crime. Pan
Tilt Zoom Cameras These types of CCTV cameras
allow a person controlling the surveillance of an
area to move the camera remotely, usually with an
RF or wired controller. Most movable cameras
allow the person monitoring it to move the camera
from right to left , up and down.
9
Cameras with Special Accessories Certain CCTV
cameras have special functions that are made for
specialty uses. For instance, there are extremely
small surveillance cameras that are used for
spying (Nanny Cams), night viewing, are vandal
resistant, and that are specifically made for
indoor or outdoor uses. Wired Vs. Wireless
Connection There are two main types of
connections for CCTV cameras a fixed cable or a
wireless connection. Fixed Cable Connection Fixed
cable connection means that the camera is
physically connected to the monitor or recording
device via a cable. Coaxial cables that are
similar to normal home TV cables are usually
used. Lengths come in 25, 35, 50, 100, or 500
feet. As the distance increases, signal quality
decreases. For distances longer than 100 or 200
feet, purchase higher quality coaxial cables such
as RG59 coaxial cable for distances up to 600
feet and for distances more than 600 feet, but
less than 2,000 feet, purchase CAT5 cable.
10
Wireless Connection Most wireless CCTV cameras
use the 2.4 Gigahertz frequencies to transmit
their video images to a monitor or DVR (digital
video recorder). Usually, frequencies can be
slightly changed to have more than one group of
cameras in a specific space. Wireless CCTV
cameras that use this frequency can easily
transmit through most walls and obstacles.
However, each individual location will have its
own operating limits. Expect most wireless CCTV
cameras to send data to a range of about 200
feet. However, many will more likely work well
when transmitting less than 150 feet. A clear
line of sight transmission will always work
best. Obviously a wireless connection allows
greater freedom to place CCTV cameras almost
anywhere. While wireless CCTV cameras transmit
their video images to a digital video recorder or
monitor, many of these types of cameras must be
plugged into an electrical outlet. There are,
however, some CCTV cameras that are battery
operated.
11
Tape vs. Digital Video Recorders There are two
main ways to record video images that CCTV
cameras capture. They are analog tape and digital
video recorders. Most analog video recorders use
VCR tapes or standard VCRs to record the images
or special security time-lapse VCRs to record
images for a longer period of time..
VCR Tape Recorder A tape recorder such as a
security-time lapse VCR can record CCTV camera
images in either black and white or color for
2,4, 6, 8, all the way up to 960 hours, which is
40 complete days. The determining factor is how
many frames per second users intend to record and
how many cameras are hooked up to the VCR for
recording. For instance, if a user records 30
frames per second (real time video), he/she will
only be able to get a few hours of video captured
on the recorder. If users record one frame per
second or less, they can record for dozens of
hours before the video tape is full. VCRs are
very practical, very reliable, and extremely
affordable.
12
Digital Video Recorders There are two types of
DVRs (Digital Video Recorders). They are either
stand alone devices or hard drives that are
connected to a computer system. DVRs work similar
to VCRs, but the images they capture from the
CCTV camera is digital. The amount of digital
images captured on a DVR is determined by a few
factors including the frames per second recorded,
the amount of cameras hooked up to the DVR
device, the resolution that the DVR saves the
images at, and the video compression used (e.g.
MPEG4). For a common set up, where 4 cameras are
shooting at 30 fps and an image resolution of 320
X 240 is being used, each camera only records
when motion is on, and MPEG4 compression is used,
users should be able fill up a 20 to 25 GB hard
drive in about 80 hours.

What is Digital and Compressed Video

• Digital refers to the process of digitizing or
  sampling the CCTV analog
• video to transform an analog signal to a digital
  format
• Digital (uncompressed) 8-10bit video used by some
  CCTV fiber
• transceivers this is not IP video
• Compressed (or encoded) video removes some of the
  redundant
• information in order to reduce data rates
• Lossless removes redundant information without
  affecting picture quality
• 45-90MB data rate
• Lossy results in some reduction in video
  quality (resolution, frame rate,
• color depth) over uncompressed image 56kbps to
  10MBps

15
How Does Digital CCTV Work?
Digital CCTV is a relatively new technology that
has proclaimed itself to be the next level in
security monitoring systems. Recent advances in
technology over the past couple of years has made
digital CCTV available and affordable for
virtually anyone to implement on their
premises. Versatile in design, digital CCTV
operates across a standard ethernet, so no extra
wiring is required in the majority of situations.
Once installed on your premises, your digital
CCTV network can be added to quickly and easily
simply by installing new CCTV cameras and adding
these to your CCTV software package. Once your
network of CCTV cameras have been installed on
your site, you are able to analyse both live and
historic event-based video clips through your PC
monitor using the CCTV software supplied with
your system.
16
Digital CCTV is unique in that it will only
record images when movement is detected. This
ultimately means that you will only have CCTV
footage of activity when something occurs across
the camera's field of view. The quality of the
footage generated by your digital CCTV cameras
means that evidence quality images are generated,
which can be used in a court of law to prosecute
perpetrators. Analogue CCTV systems invariably
are unable to do this. The integrational
capabilities of digital CCTV mean that in
addition to working extremely well as a
standalone security system, it can also be
connected to other installed security equipment.
17
What are IP cameras?
A growing branch in CCTV is internet
protocol cameras (IP cameras). IP cameras use
the Internet Protocol (IP) used by most Local
Area Networks (LANs) to transmit video across
data networks in digital form. IP can optionally
be transmitted across the public internet,
allowing users to view their camera(s) through
any internet connection available through a
computer or a 3G phone. For professional or
public infrastructure security applications, IP
video is restricted to within a private network
or VPN

Technological developments
WATER PROOF CCTV

• Computer controlled analytics and identification

• Todays High-definition CCTV cameras have many
  computer controlled technologies that allow them
  to identify, track, and categorize objects in
  their field of view.

26
Video Content Analysis (VCA) is the capability of
automatically analyzing video to detect and
determine temporal events not based on a
single image. As such, it can be seen as the
automated equivalent of the biological visual
cortex. A system using VCA can recognize changes
in the environment and even identify and compare
objects in the database using size, speed, and
sometimes color. The cameras actions can be
programmed based on what it is seeing. For
example an alarm can be issued if an object has
moved in a certain area, or if a painting is
missing from a wall, and if someone has spray
painted the lens.
VCA also has the ability to track people on a map
by calculating their position from the images. It
is then possible to link many cameras and track a
person through an entire building or area. This
can allow a person to be followed without having
to analyze many hours of film. Currently the
cameras have difficulty identifying individuals
from video alone, but if connected to a key-card
system, identities can be established and
displayed as a tag over their heads on the
video. http//www.cctvcams.in

• Facial recognition system Is a computer
  application for automatically identifying or
  verifying a person from a digital image or a
  video frame from a video source. One of the ways
  to do this is by comparing selected facial
  features from the image and a facial database.
• The combination of CCTV and facial recognition
  has been tried as a form of mass surveillance,
  but has been ineffective because of the low
  discriminating power of facial recognition
  technology and the very high number of false
  positives generated. This type of system has been
  proposed to compare faces at airports and
  seaports with those of suspected terrorists or
  other undesirable entrants.

28
Computerized monitoring of CCTV images is under
development, so that a human CCTV operator does
not have to endlessly look at all the screens,
allowing an operator to observe many more CCTV
cameras. These systems do not observe people
directly. Instead, they track their behavior by
looking for particular types of body-movement
behavior, or particular types of clothing or
baggage.
