The Necessity Of Spy Electronics

By Kingston Amadeus

When most people think of electronics, they think of audiovisual devices like cameras, computers, TVs, and recorders. Spy electronics also encompass all of things. The main difference is that while all of the above items are mainly used for entertainment purposes, spy electronics are meant to be used in surveillance. These electronics can be very technologically advanced, and some of them can be so well disguised that others do not even realize that they are being watched or listened to.

Spy electronics are necessary to make the whole surveillance profession work. After all, if you do not have recording equipment, or equipment to recover the recordings, then it is no good. You cannot perform effective surveillance. Additionally, electronics in places like command centers and control rooms are what coordinate the efforts of individual pieces of electronic equipment and they also direct the surveillance efforts. In today's world, the professional needs electronics to be an effective bounty hunter or private investigator.

Spy electronics are not only necessary for people like PIs and bounty hunters. The military makes extensive use of these things. Indeed, their electronic spy devices include things like unmanned spy planes and prototypes for other high tech equipment. Police and government intelligence agencies also make heavy use of spy electronics. Wiretaps and the equipment to listen to what is heard fall into the category of electronics. Other forms of surveillance, such as cameras and other listening devices are also necessary.

Other spy electronics that also perform useful functions include TVs and other screens that display information and computers that keep track of tracking devices and maps. Additionally, computers can direct remote cameras to find new angles and they can also record information and display it a way that is more useful to the user. There is no doubt that computers are becoming very important pieces of electronic equipment that can be used for surveillance purposes.

Without spy electronics, the possibilities for evidence and intelligence gathering, whether for national security or for your divorce case, would be much more limited. Technology has made it possible with a variety of advancements to find out just about anything that you might need to know to help you maintain your quality of life. And it is all made possible with information gathered and analyzed with the aid of spy electronics.

CCTV Security Camera Information For Non-Technical People

By John Bart

Get a good face shot!

Use Higher quality cameras at entry areas Doors, gates and other entry areas need a good quality, high resolution camera to record a good 'face shot.' The video from this camera should be considered a highly valuable since it can be used as evidence in identifying a person in a court of law.

Wide Angle Cameras for large surveillance areas

Once you can get a good shot of a persons face, you should use a wider angle camera lens for the interior surveillance spaces of the building. Using color cameras inside your building is a good idea because you can readily identify a person by the clothes they are wearing. Used in conjunction with the face shot at the entry point, you have an excellent record of all people and activities in your surveillance areas.

Use Bullet Security Cams and Dome Security Cams!

They're Low Cost, High Performance, can be uses indoors and outdoors and available in Color or B&W. Dome cams and bullet cams come in many low cost models. Good quality B&W cams start at less than $80 and good color cams start at $150. When it comes to budgets, having a low cost black & white camera is better than no camera at all.

Black and white cameras have advantages over color security cameras

Most B/W cameras can see in lower light and have higher resolution than color cameras. If most of your surveillance goals are at night and your budget is limited, a black & white camera may actually be your best solution.

Professional and Standard C-Mount Cameras

If your budget permits, a c-mount camera offer a big advantage over other cctv cameras.

C-Mount or CS-Mount?

C-mount and CS-Mount lenses offer similar performance, the only real difference is the way the lens mounts to the camera. And that's not a problem since the adapter to convert 'C-Mount' to 'CS-Mount' comes with the camera. This enables the camera to use either C-Mount or CS-Mount lenses.

Lenses can be changed!

They simply unscrew from the camera body, just like the way lenses are removed from traditional cameras. There are lens options from 2.5mm up to 500mm providing many different magnification options.

In general, an 8mm lens is like a 4mm lens magnified 200%. A 16mm lens is like the 4mm lens magnified 400%

Outdoor Housing

C-mount cameras can be used outside when put in an outdoor camera housing like the photo to the right needed to protect the camera. Heat and Fans are necessary in the 'extreme climate areas.' See our outdoor housings

Varifocal Lenses

You can also use a varifocal lens on a c-mount camera body. The higher millimeter of the lens the further distance viewable. C-Mount cameras can use a varifocal lens. This is a huge advantage because you can adjust zoom and focus. With Varifocal lenses the focus can be varied from 5mm to 20mm or more.

Even after installed, the varifocal camera lens can be adjusted to choose a variety of focal distances and angles of view. An example of where you might use a varifocal lens is outside (or inside) a warehouse or parking lot where you need more distance than 35 feet.

Pan-Tilt-Zoom (PTZ)

Pan-Tilt-Zoom Cameras also known as PTZ cameras are excellent devices to use when you want to 'look around' your surveillance area.

PTZ cameras allow you to pan an entire room, tilt up and down and zoom in on anything or anybody within the sight of the lens.

PTZ cameras can be set to automatic or manual mode or both. In automatic mode, hundreds of points can be set for the camera to look at. The duration that the camera looks at a given set point can be adjusted from less than a second to as long as you would like.

There are some variances in different models. Some have 17x zooms while others have 50x zooms or more.

Night Vision Security Cameras

By Damian Salvio

As the name implies, night vision security cameras are used to capture images in darker environments. There are day/night vision cameras that allow you to see intruders trying to enter your home day or night time. These cameras ensure better security to your property.

Most night vision security cameras have infrared LED. Cameras using thermal imaging technique capture the heat emitted by objects to reveal them to the viewer. All humans emit some heat in the form of infrared light. The infrared detectors of the cameras pick these lights and a comprehensive temperature pattern is generated as a thermogram. This thermogram is converted to electrical impulses and a signal processing unit translates these signals into a display. Night vision security cameras using light enhancement involves converting small amounts of light into electrical energy. These electrical signals are amplified and then converted to light and displayed.

The range of night vision security cameras vary considerably. Most small outdoor night cameras cover 7 - 15 meters, whereas most professional security systems cover up to 30 meters. The power of night vision security cameras are represented in Lux rating. Lux rating is the minimum illumination in which a camera can pick up an image. The closer the Lux rating is to 0, the better the camera's performance in low light situations.

Like regular security cameras, night vision security cameras are also capable of sending images to VCR, PC or to a distant destination through the Internet. These images can also be recorded in tape, hard drive or any other storing device. The day/night cameras will have extra sensitive imaging chips which allow them to capture in light situations without using infrared LED. During daytime, they provide color images and during nighttime they provide black and white or green phosphor shades.

Modern night vision security cameras can be used both as indoor and outdoor units. They are provided with weatherproof and waterproof casings made of metals. Most have triggering alarms or lightings which start automatically on seeing any moving object. Many night vision security cameras also have microphones to pick up sounds. A lot of cameras have remote controlling facilities. The price range starts from $80.

Role Of Teleprompters In Closed Captioned Systems

By Adrienne Arno

Closed captioning is the process that makes it possible for individuals who are hearing impaired to access the dialogue on television programming by displaying the copy on the lower third of the monitor. The FCC passed the first closed caption ing regulation in 1993. This compelled all analog televisions with displays larger than 13 inches sold and/or made in the US include a integrated decoder to display closed display. Congress became involved several years later with the 1996 decision to demand all video programming distributors including cable TV, broadcasters, and satellite distributors to close caption their programming.

The FCC furthered this decision a year later with a specific transition calendar that required all distributors to increase the amount of programming that contained captioning. Finally, in July 2002, the FCC passed a second law requiring digital television receivers to add closed captioning display mechanisms.

Being involved in the communications industry while working at the American Movie Company has given me a personal experience at the influence these decisions have had on most studio productions. One of these effects has been how video and television productions have adapted the use of the teleprompter.

While we recognize why closed captioning is important, some don't know how the teleprompter plays a key task in the delivery of closed captioning to your TV. There are two sectors into which closed captioning systems are divided: On-Line systems and Off-Line systems. This is when the teleprompter becomes important.

On-Line captioning is the teleprompter-based solution prevalent with broadcasters and news stations. In this circumstance, pre-scripted stories are fed from the newsroom automation system to both the teleprompter and to the closed caption encoder. This information usually doesn't contain closed caption control codes but rather depends on the encoder inside the screen itself to add the right codes each time an ASCII carriage return is received.

The esteem for this type of system is based on the fact that neither a steno-captioner nor a computer with costly software is necessary. In many instances, the teleprompter system is already on-site and closed captioning can be added for only the cost of the encoder.

Closed captioning is an exciting field that offers many opportunities for both the television broadcaster and the video producer. Hopefully, this introduction will help you to make intelligent decisions as you choose a caption service provider, obtain equipment, or offer advice to those who will make these choices.

It's not only the impaired who are also grateful that this standard exists but also those in other countries who get involved in translations of English movies.
