Ensure Safety with CCTV Security
Systems
September 28th, 2009
In this day and age, you can't
be too complacent about the safety of your own home.
Crime abounds everywhere, and even the seemingly
safest areas are not spared. Crime prevention is a
near impossible feat. However, crime detection
leading to prosecution is not, thanks to CCTV
security systems.
CCTV Surveillance Defined
Having a CCTV security system for video surveillance
and live monitoring purposes is like having an
entire television network devoted to the safety of
your home. CCTV security systems may comprise of a
single or a group of surveillance cameras on a
private in-home network. They can be linked to an
observation monitor with well-placed cables or even
wirelessly.
CCTV security systems are
commonly used in areas in need of high-security,
such as banks, casinos, and airports. But because
CCTV security systems are relatively inexpensive and
simple to use, they are now being used in private
homes to bolster homeowners” peace of mind.
CCTV Surveillance vs.
Crime
CCTV security systems rapidly gained popularity as
an aftermath of the terrorist attacks on London's
public transport system. Surveillance videos
identified the men responsible for the attacks,
leading to their capture and eventual prosecution.
This proves that a CCTV
security system is an effective tool for crime
detection and can provide solid evidence.
Furthermore, with constant vigilance, a CCTV
security system is a powerful deterrent and may even
stop crime before it actually happens.
CCTV Cameras and Your
Home
CCTV security cameras are simple enough to be used
at home. They can take images with resolutions as
high as 1600 x 1200 pixels on a time lapse or motion
detection basis, depending on your setup. Some CCTV
security systems have add-on features like
tilt-zoom, low light, and infrared. CCTV security
cameras are relatively inexpensive. Prices vary,
depending on factors such as size, type, display,
resolution, zoom, and connection. CCTV security
cameras are commonly available as domes, bullets,
and standard c-mounts. They are available in black
and white or colored, with audio or without audio.
With a good setup, CCTV
security systems can monitor up to 16 rooms and
areas in your home, all the while providing clear
and highly visible images. You can monitor your
garage, your kitchen, your front yard, and even your
mailbox. CCTV security systems are able to record
suspicious activities real-time. The cameras
subsequently transfer the captured images to a PC or
laptop through a USB, coaxial cable, or a wireless
adapter.
Study your needs before you
install your CCTV security system. Consider the area
that you want covered, as well as consider future
expansion. If installed outdoors, invest in
specialized weatherproof housings and proper
protection from vandals. Lighting is also an
important thing to consider. The absence of proper
lighting will produce muddy pictures that could end
up being useless. Lastly, ensure that you have a
stable power source and power supply.
CCTV Surveillance and
the Law
Video surveillance is subject to privacy laws. Your
home is your private domain and you have every right
to protect it. A CCTV security system is a powerful
addition to your home security system. However, you
have to check the legality of your system. It is
best to consult with a lawyer or at least get in
touch with your local law enforcement department to
ensure that all local, state, and federal
requirements are met.
How Can a CCTV Security System
Help?
September 21st,
2016
One of the most frequently asked
questions about the CCTV system is that inquiring
upon its nature. CCTV, short for Closed Circuit
Television, is a surveillance technology which
monitors a wide range of activities and
environments. The CCTV system is based on a
communication link between a camera and a specific
monitor. Many towns and cities resort to CCTV
security systems, which has led to an unprecedented
growth in the amount of money spent on surveillance
systems. CCTV security systems are now used in
public areas such as city centers, parking lots,
public facilities, buses, taxis, phone booths etc.
Actually, statistics say that the surveillance
industry grows with up to twenty percent every year.
CCTV security systems are also installed on private
property, not just public places.
Evidence of domestic violence
can be collected by means of a CCTV system,
installing a camera inside the victims’ homes. A
similar type of surveillance is used inside
hospitals in cases of supposedly abused children, in
order to monitor their parents’ activities and
behavior.
In the early stages, CCTV
security systems were used to decrease crime rate
such as burglaries or car thefts. More recently,
CCTV systems pick up on more minor offenses such as
urinating in public, drunkenness, traffic violation.
Those who evade the meters in a parking lot can also
be caught on camera. Underage smoking, sexual or
racial harassment, drug use, all of these crimes are
the subject of CCTV system monitoring. Public order
is now more likely to be kept with the use of CCTV
security systems, which have become the solution to
the serious problem that is
urban dysfunction. But
the police are not the only promoters of security
through CCTV systems. Politicians also encourage
installation of such systems in order to control
crime.
The CCTV system also has its
opponents, but whenever these critics speak up,
people who are frightened by crime consider them to
be nothing but enemies of everyone’s best interest.
As far as the technology used
in a CCTV system goes, it suffices to say that some
of these systems can be very sophisticated. They can
be assisted by a computer, can detect motion, can
have night vision and images of excellent clarity.
Another amazing thing about the cameras on a CCTV
security system is that they can focus on a single
object from a crowded environment and follow that
one object. They provide high definition images from
which faces can be recognized. The time needed for a
system to identify one face out of several thousands
is less than a second. The system is mostly used in
airports where terrorists may enter a country.
Since the CCTV cameras have
often become targets of attacks, more and more of
them now have a casing which is bullet proof, or are
covered by other cameras installed nearby.
The question still remains
whether CCTV security systems reduce crime. The
answer is that they are most likely to prevent it.
Those in favor of such surveillance systems have at
least one argument. CCTV systems reduce the number
of the so-called opportunistic crimes, that is the
crimes committed when people decide to take
advantage of a certain situation. In the same way,
crimes in parking lots have reportedly dropped by
almost ninety percent.
The conclusion is that,
although CCTV security systems may not be as
efficient as their supporters portray them, at least
they appeal to common people, who now feel much
safer when going shopping, for instance.

Security Camera Systems
September 8th, 2009
Security of one’s home is the
primary concern of most people. For those staying in
a society or an apartment block, it is a factor that
is taken into account by the builders and the
occupants, so many times there will be a security
system in place. There could be a guard physically
present or an integrated calling system where the
occupants open the main door through an electronic
medium.
Security
cameras have taken their place in the forefront of
security measures in the corporate and retail world.
Technological advances have ensured that it is no
longer an expensive proposition, and the investment
is not considered frivolous anymore.
Banks, large and small retail
outlets, offices, or any place that perceives a
possible threat to the public all go in for this
option. Some go to the extent of using fake or dummy
cameras just to create that feeling of insecurity in
a prospective burglar.
Cameras and related equipment
come in various price ranges so you must have a
clear idea as to how much you are willing to spend.
Then, based on that, decide whether it should be a
wired system or not. The equipment has to be placed
in such way that there is a power connection with
backup available and no other electronic item close
by that could cause signal transmission problems.
All these considerations will
ensure that you get the right surveillance setup to
suit your setup and budget. A few things to keep in
mind would be that dummy cameras by themselves are
not very practical and do not offset the cost, and
they could bring on legal hassles. People should be
aware that there is a camera system in place so they
don’t indulge in any untoward activities. Sound
recording is considered illegal so avoid systems
with an audio facility.
Security cameras range from
infrared to bullet, which are popular as they are
portable and come as a complete unit, ready to
assemble. They should also be weatherproof in order
to handle indoor and outdoor security.
Go in for a system keeping
all your personal requirements in mind, and you will
definitely not regret the time and money spent in
setting up a security camera system.

Why Use Computerized Close
Circuit TV
August 26th, 2009
CCTV is a popular device used in
surveillance purpose around the world. It’s
elaborated as Closed Circuit Television which uses
video cameras to broadcast signal in such a fashion
that differs from the sense of simple broadcast TVs
which functions brazenly. CCTV Security adds extra
security.
However, CCTV
security system doesn’t transmit brazenly, due to
its intended use to guarantee security it may be
used to broadcast signal in a point to point
wireless link. For instance, it may be used thru
Microwave link.
CCTV security has the
features of capturing videos and broadcasting those
to a place as needed. It can preserve signals for a
specific or uncertain period depending on the design
and purpose of its use by the grace of DVR ( Digital
Video Recorder ). It can do some forensic studies by
analyzing the signals at a given time with the help
of VCA ( Video content research ). If the
computerized system detects the presence of a
dangerous thing of a particular choice, it can
generate alarms by email or any other convenient
way. It is also feasible to generate alarm as mobile
SMS. Thus it’s being proved as a security system.
These days, CCTV security is
used in Banks, Casinos, airports and many other
critical places that need to be secured. It’s
probable to grasp all the areas regardless of the
ability of someone’s entrance or obstruction. As men
like to be freed from hassles, it’s scientifically
utilized in industry to see the motion of parts or
objected scene, safe transportation and even in the
street in order to serve a selected point of
security.
CCTV security system is now
computerized and an operator can control the system
as a full. It can monitor the people of a specific
area, the motion of the people and even in some
cases, it can establish the age of a person. It may
also monitor any objects that are subjected to be
noticed for a particular reason. As an example, in
an airport, it is used to check unwatched bags.
lately, we have noticed many
situations that have been tracked successfully by
CCTV security. It’s being generally used by the
investigators to see bad guys or crimes up to an
acceptable level. At any place, an intruder can
simply be monitored and the video signal can be
passed on a remote place, as an example, from the UK
to India immediately. The offenders of BDR mutiny in
Bangladesh are being spotted with the aid of CCTV.
It uses DVR or Digital Video
Recorder to catch and record the incidents at a
particular moment and it can retain those for a
number of years. This feature has opened up amazing
values to analyze wrongdoing in the society.
An ATM of a Bank is being
kept free of intruder by aid from CCTV security ;
again it could be a dangerous tool if the criminal
uses same technology to steal the PIN of the
subscribers. They can do so by implanting a tiny
CCTV at the ATM. Despite this opposite application,
modern civilized society has no way to deny the
benedictions of this helpful device.
CCTV security could be called
the mirror of our society, as it’s being employed to
serve such purposes.

CCTV Security Cameras Basic
Features
August 21st, 2009
CCTV security cameras are
cameras that take a motion picture and forward it to
a central security board (usually a computer) on a
closed circuit, inaccessible by the public. CCTV
cameras have been in use for several decades now,
yet the idea has not changed much since their
introduction. The two significant changes are their
availability and their recording method. Most
cameras today record the motion picture digitally,
and the data is stored in digital form on a hard
drive or other media. With the raising popularity of
such surveillance equipment, their price has been
falling steadily, making them available for small
business owners as well as citizens who want to
protect their home and family. This article is
written for people who do not yet have experience
and knowledge about security cameras.
Let’s talk about the
main features of CCTV security cameras.
Wireless vs. wired
Wireless cameras use radio
signals to transmit the picture to the main security
board, and usually have their own built-in,
rechargeable power supply. They are easy to move,
and can be installed discreetly in places where
installment of a wired camera would be unfeasible.
Their price might be a bit higher than of wired
cameras though, and a wireless camera’s feed can be
easily ‘hijacked’ or even modified by an experienced
hacker from a distance. You should only install
wireless cameras for short-term surveillance ( less
than a year).
PTZ
PTZ stands for Panning,
Zooming and Tilting. A PTZ camera can be controlled
by an employee, who can use it to follow a
suspicious person, or just scan a wider area. The
pro is that a huge area can be surveyed by a single,
well-placed PTZ camera. The con is that you need a
person controlling it. Installing more static
security cameras is a better solution, but is more
costly.
Dome cameras
Dome cameras are security
cameras inside a small semi-transparent hemisphere.
The basic idea is that people can’t see where the
camera is pointed. It is more discreet and has a
higher retentive efficiency.
Color cameras
Some security cameras record a color motion
picture, which is useful when trying to identify a
criminal. However in any other cases it’s pointless,
and a color video takes up more storage space. Color
cameras are good for not security related uses, and
cost more than black and white cameras.
Fake cameras
Fake cameras offer a very cheap alternative
to real cameras. They are only useful for their
retentive effect. I don’t recommend using fake
cameras for two reasons: they are useless for
surveillance and identification, and someone will
eventually find out that they are not real cameras.
Fake cameras = fake security!
So these are the most common
features of surveillance cameras in the market
today. I hope after reading this article, you will
be much more confident in choosing the CCTV security
cameras that fit your needs.

Protect Your Home or Business
with CCTV Security Systems
August 17th, 2009
With so many reports of
burglary, theft, and home invasions recently, you’re
probably very concerned about the safety of your
home or business. There is a definite need for
concern. Many homes or businesses are burglarized
because they do not have a dependable security
system in place.
CCTV
security systems are growing in popularity for all
sorts of purposes. As the need for security cameras
grows, CCTV technology is also growing by leaps and
bounds with new innovative features to make video
surveillance more dependable than ever.
What is CCTV?
CCTV stands for “closed
circuit television” and is a television system that
is meant for private use only, not for public
broadcast. CCTV is used for many purposes. It might
be used to monitor a nanny or a caregiver for an
elderly person. As an employer, you might use it to
keep an eye on your employees and to monitor daily
operations. CCTV can be used to observe public
places by government or law officials such as parks,
housing or apartment developments, and car parking
garages.
Protection and
Prevention with CCTV Security Systems
Using a CCTV system can
dramatically reduce your risks of becoming a victim
of crime. It can protect your child, your elderly
loved one, your home, or your business by allowing
you to observe what’s going on either secretly or
openly. A CCTV camera can be placed almost anywhere
in any room where sufficient lighting is available.
Many of the new model CCTV cameras are wireless and
can be operated on batteries. There are external
day/night cameras as well for surveillance outdoors.
Types of CCTV
Surveillance Cameras
There are many different
types of CCTV security systems available. If you
want a “hidden” camera, there are miniature cameras
and even CCTV cameras that resemble everyday
objects, such as the pen camera, smoke alarm camera,
and the clock camera. These objects appear to be
normal, but actually have a CCTV camera hidden
inside. There are covert wireless cameras, multiple
cameras with receivers for observing a broad area,
dome-covered wireless cameras, and wireless video
senders.
Benefits of a DVR
Security System
A DVR security system is a
digital video recorder that can be used in
concordance with the CCTV system. Unlike VCRs, DVRs
enable you to record for many hours at the full
digital quality. Also, you are able to set it for
timed recordings or continuous recordings. Some
unique features that you might find with a DVR
system include quick replay search using date, time,
or day, multiple camera recordings and display, a CD
writer for backup, motion detection, remote control,
and more.
With these helpful
surveillance items, you can feel safe and secure at
your home or business. They can be used as a
deterrent to thieves or to catch them in the act.
There are also other great security products for
creating access control to certain areas of your
home or business, vehicle security, computer and
Internet security, and other uses.
Use online resources to find
the right CCTV security system for your home or
business. You won’t regret it!
