What Is CCTV?

CCTV stands for closed circuit television. It is a system where the circuit is closed and all the elements are linked. This is different from broadcast T.V. where tuners pick up the signals from the airwaves. For purposes of this article, linked means connected by wiring, microwave, infrared, etc.

What’s It Used For?

The most obvious and common use for CCTV is for security. This type of installation is used in a variety of locations such as stores, banks, and government buildings. However, there are so many other uses. It can be used for monitoring traffic. It is used in sports stadiums to focus on the audience. It can be hidden in trains and buses to detect vandalism. It can be used to monitor animals in a zoo. It can even be used to reproduce infrared vision. The applications are almost limitless.

What’s In It?

It all starts with the camera. This creates the picture that is transmitted to the control area. Most CCTV cameras are not fitted with lenses. They must be obtained separately and screwed on. There is a standard screw thread although there are different mounts. Not all lenses have focus adjustment. Most have iris adjustment. Some wide angle lenses do not have a focus ring. There is a BNC jack for connecting the video cable. In the case of line powered cameras, this coaxial cable also provides power. The monitor is what receives the signal that the camera creates. A CCTV monitor is similar to a television set but it does not have tuning circuits.

Simple CCTV systems consist of a camera connected to a monitor with coaxial cable. This cable also carries the power needed for the camera. This is called a line powered camera. The Pye Observation System was such a system and was popular during the early days of CCTV. It was affordable and could be set up with a minimum of difficulty. The next big step in the technology was allowing for four cameras to be connected to the monitor simultaneously. The view could be programmed to cycle through the available cameras or go to a particular camera chosen by the user.

Record For Posterity

Another big advance was when footage could be recorded and stored. The footage would be played back according to the viewing cycle the user chose. Once the footage is recorded, it cannot be changed to go to a different camera. The next step would be cameras that were able move and swivel. Simple platforms that move on a horizontal plane are called scanners. If a platform moves on both vertical and horizontal units it is called a pan, tilt unit.

The concept of CCTV is simple enough to understand. It is the application of such technology that still holds many undiscovered gems. Such a simple concept can be tapped for its limitless potential. And for the end user, it can serve as a great tool to accomplish many different things. In the end, that is the most important thing.

Cctv Surveillance Systems: Those New Security Guys

Don’t look now! Someone’s staring at you from that far wall behind the artificial potted plants in this busy hotel lobby. But there’s no need for that furtive glance like you have some lint on your shoulder. There’s no need for those tiny furtive steps either. No one’s stalking you. It’s just the hotel’s CCTV surveillance system. The hotel has recently been caught up in the wave of video surveillance. That someone staring at you from across the room is just the camera from the newly installed CCTV surveillance systems. In hotels and in places where there is high human traffic, state of the art CCTV surveillance systems have been mounted for purposes of safety and as crime deterrents.

That Constant Fear

The world, it seems, is gripped by fear of terrorist attacks. In fact, after 9/11, it seems to be a Herculean effort to make life go on – do business, travel, interact with others in densely populated places. After all, if there’s anything 9/11 has shown us, it is that a bomb could go off in a sidewalk while you are having an al fresco lunch with a colleague, or blow up the trans-continental plane you are in while it’s in in the air, cruising at 125,000 feet.

The security guys you see milling about do not reassurance you. You have always felt that security guys patrolling public places have a very limited capacity for preventing crime. They only act when something happens in their line of sight. By then, however, you’d be beyond help.

You’re Safe Now

Installed in a strategic spot and equipped with cutting edge technology in surveillance cameras, CCTV surveillance systems can record everything that goes on in its line of focus. These recordings can later be retrieved and analyzed to recreate scenes.

Software developers now see the potential of CCTV surveillance systems in preventing a repeat of large-scale terrorism after the 9/11 attack at the World Trade Center. These developers are working hard to develop programs for surveillance systems, among them an important feature known as face recognition.

With face recognition installed in CCTV surveillance systems, it is now easy to recognize certain key features in the face of an individual. This face will be compared to a host of faces from a database of mug shots and photographs. A person flagged as dangerous can then be prevented from gaining access to buildings or public transportations, thus thwarting any planned attack or escape.

Big Investment That Pays Off

CCTV surveillance systems today now boast of functionalities not seen in the video surveillance systems of the past. This time, CCTV surveillance systems have

1. motion detection. This means that the surveillance system only records footage when movement triggers the surveillance system.

2. resolution as clear as day. Grainy footage is not a problem anymore with some video surveillance cameras featuring 1600 x 1200 dpi, or even more, resolution.

3. night and infrared vision. Even with low or minimal lighting, these new surveillance systems can record images with infrared technology.

Government administrators are seeing the positive side of surveillance systems. In fact, after 9/11, federal budget is flowing in for these new security measures. There are states which require the installation of surveillance systems in business establishments before these businesses can operate.

So, there is really no need to be afraid. CCTV surveillance systems, those new security guys, have your back. They are always watching.

Wired Vs Wireless Security Systems

By Brian on Monday, November 7th, 2011 | No Comments

By Richard Armen

Technology has a way of evolving quickly, and the world of home security is no exception. If you’re looking to improve your home security – whether through a whole house alarm system or just a few well-placed security devices – one of the first decisions you’ll need to make is whether to use a wired or wireless system in your home.

Wireless home security devices represent the cutting edge of technological change. But are they right for your home? Just a decade ago, wired systems were the universal standard, regarded as safer than the wireless systems then being developed. Now, whether you’re looking to upgrade your home security system or install one for the first time, you’ll need to weigh both types, as there are pros and cons associated with each.

Wired home alarm systems, the traditional type that have been used for decades, rely on an electrical circuit, not unlike the one allowing the lights in your home to turn on. When you ‘arm’ the alarm system, the circuit is closed. If someone opens a door or window or otherwise sets off the alarm, the circuit is opened, causing the alarm to sound. This is a very reliable form of technology, meaning that your alarm system is likely to work in all scenarios.

Although wireless security has come a long ways in the past ten years, wired systems remain the least expensive and most reliable choice. Still, there are some downsides. Wired alarms require the running of wires. Besides needing to hide wires, you may not want to cut into walls to install the system, especially if you don’t plan to live in the same place for more than a couple of years. They are less flexible because the alarms must be installed in areas where the wires will be easy to hide. This tends to get complicated, often requiring professional installation.

If you are looking for a system that is easy to install, offers flexible security options, and can be taken with you when you move, consider wireless home security. These systems run on battery power. The alarm is triggered by radio signals transmitted by sensors – such as those placed in a door or window – to a control unit. These can easily be installed in a weekend. Use them around your whole house, or just on the doors and windows you feel are the most vulnerable to intruders. Each individual alarm can be armed, regardless of whether the rest of the system is turned on.

In addition to the choice between wired and wireless alarms, you’ll also have to make the same decision if you choose to install cameras. Again, there are benefits and drawbacks associated with each types. Battery-operated wireless cameras can be installed anywhere, but go through batteries in just a day or two, making them an inconvenient choice if you want 24-7 surveillance. On the other hand, they might make great nanny cams when you’re out of the house. If you want the camera to be on all the time, look towards traditional wired surveillance cameras.

Dummy Cameras Provide Added Security Without The High Costs Of Security Cameras

By Brian on Thursday, November 3rd, 2011 | No Comments

From the outside, dummy cameras appear to be real security cameras, but they lack the expensive recording components inside. Without physically taking a dummy camera apart, there is no way of knowing it is actually a fake. Dummy cameras provide added security without the high costs of additional cameras. When a criminal sees a security camera, or what is thought to be one, he is likely move on. When faced with a tight budget, dummy cameras are an excellent alternative to fully functioning security cameras.

Various dummy cameras offer an assortment of capabilities, and it is important that you think about the different features and abilities available to you when choosing dummy cameras. Your choice of dummy cameras depends on which elements you feel are the most important and which ones fit your needs and budget the best.

Features

- Flashing or steady LED “recording” light,

- Panning motion or steady,

- Actual camera housings or look-alikes,

- Bullet style or dome style, and

- Indoor or outdoor structure.

Choosing dome style dummy cameras will lead burglars to believe you have the ability to view a 360-degree range of an area, while bullet style dummy cameras give off the perception that a close-up picture of his or her face is being recorded.

Home Use

If you have already installed surveillance equipment in your home, but would like to give the impression of having more cameras, dummy cameras are the way to go. Burglaries are not hasty crimes. Homes are usually staked out by burglars before any crime takes place, and the presence of cameras, especially more than one, is enough to send any burglar on his or her way.

Business Integration

Each year in the United States, retailers lose approximately 10 billion dollars due to shoplifting and 15 billion dollars due to employee theft. The strategic placing of dummy cameras is an efficient and inexpensive way to deter pilfering. Placement should be well thought out, keeping in mind the three locations which will get the most attention: (1) the front entrance (2) the back corners (3) the back door or loading dock.

The power of suggestion offered by the presence of dummy cameras is an effective tool in lowering your costs due to theft.

You deserve top notch security of your home and your business, no matter your budget constraints. The integration of dummy cameras is a cost-efficient and unproblematic way to ensure the safety of your home, family, business, and employees.
