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 homeownersĒ 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,

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 victimsí homes. A similar type of surveillance is used inside hospitals in cases of supposedly abused children, in order to monitor their parentsí 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 everyoneís 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.

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.

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.

However, CCTV security system doesnít 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 itís 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. Itís probable to grasp all the areas regardless of the ability of someoneís entrance or obstruction. As men like to be freed from hassles, itís 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 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.

Letís 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 cameraís feed can be easily Ďhijackedí 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 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 canít 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 itís 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 donít 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.
