Camera TNT

Consumers have been pretty receptive to the lower priced “point and shoot” models (some 5 million digital cameras were sold in the U.S. during the Christmas 2005 holiday season), but there are still some holdouts.

Great strides have been made in digital technology over the past few years, but more sophisticated digital cameras have only recently come down in price enough to attract the “serious amateur” market. In the past, the price of high-end digital camera equipment was more suited to the professional who could turn that investment into an income source.

Even traditional film buffs are slowly coming around to the benefits of digital photography. Among the holdouts, the chief problem seems to be confusion. There are so many choices, with a broad range of options, and just as many price ranges.

It’s cheaper not to make a decision, than to make a mistake.

They get lost in the terminology, and have reservations about the quality of digital photos and about the reliability of the digital cameras. With the whirlwind of innovation flooding our lives everyday, it’s become really difficult to keep up.

Technology advances, prices come down, and a deal today may be obsolete tomorrow. At least that’s what worries many potential digital camera owners.

So let’s look at five of the most common questions about digital camera photography to shed some light on the matter, for those who are hesitant about this new technology, or who have dismissed it as a mere fad.

1. Do digital cameras produce quality photos?
Digital photos can be displayed at very high resolutions, and could easily surpass conventional photographs, but many have seen poorer quality images. Early color printers could be used to print color photos from digital cameras, but the quality just wasn’t there. Blurry images on low-grade computer monitors or on the small LCD screens of the cameras themselves, do nothing to increase your confidence.

But view the high resolution images available from today’s digital cameras on a capable monitor or after being printed on one of the newer photo quality printers (using photo quality paper) and you’ll see the crystal clear quality of what is available today.

2. How durable are digital camera photos?
Digital camera photos are not stored on film. They’re stored on electronic memory devices that actually require much less care than negative film.

As long as reasonable care is taken of the particular storage device, there shouldn’t be any problems with protecting images caught on a digital camera, and you can easily make copies of the digital image files on your computer or even burn them to a CD – an option that isn’t available with film.

3. Are digital camera photos more expensive to process?
Not anymore. First, you can eliminate any poor images before printing and only pay for those that you print. With “easy share” technology and photo quality printers now available, it is both affordable and convenient to print digital camera photos.

You can even do the task yourself, in the comfort of your own home – without buying expensive development chemicals that are required for film processing! Or, you can send your images electronically to a professional processor, and receive professionally produced photos back in the mail in just a few days.

4. Can I get different effects with a digital camera?
That depends on the digital camera. High end models have built-in features that allow different kinds of effects. But even if your digital camera doesn’t have these advanced features, you can always manipulate the photographs on your desktop computer, using any image editing software.

5. Are zooming features comparable?
Here digital cameras actually have a distinct advantage over film cameras. While cheaper digital cameras may only have digital zoom (which is really just a form of in-camera enlargement that results in a lower resolution original image), high end models are available with both digital and optical zooming.

When shopping for your digital camera, give priority to the optical zoom capability and buy the highest power optical zoom that fits within your budget. Digital zoom is a nice extra, but the effects can easily be replicated during the “processing” of the image on your computer, prior to printing the images.

Most Infrared Security System will be able to capture clean images during the day which is exactly what you want. The overall effectiveness of a camera is marred if you arent also fully protected at night-time. Night-time security is vital to have because criminals will often choose to act under the cover of darkness. This is why infrared CCTV is a great all-round surveillance choice it gets good picture coverage no matter the time of day or night. As CCTV becomes more commonly used, the systems become more sophisticated, infrared CCTV for example, is now an affordable way of protecting a low-light area. Infrared closed-circuit television cameras make this a reality, effectively monitoring the darkness for your surveillance system.

Thermal Imaging – The process used by infrared CCTV cameras for night-vision is known as thermal imaging. People and objects constantly emit a level of heat referred to as thermal energy. Thermal energy resides in the electromagnetic spectrum which in turn occupies the top of the infrared light spectrum. Thermal energy is invisible to the naked eye because it is emitted from a source, as opposed to being reflected by light. Infrared CCTV cameras use thermal imaging to capture various levels of thermal energy and convert it to a light-based image that is visible to the human eye. This process of revealing the invisible occurs over several steps:

A. Infrared Lens – The specially designed lens of an infrared camera is used to focus the levels of invisible infrared radiation within its view.

B. Thermogram – Infrared detectors review the radiation focused by the lens and proceed to create a temperature map known as a “thermogram.” The completed thermogram is then translated into a series of electric impulses.

C. Signal-Processing – Once converted into electric impulses, the thermogram is sent to a chip on the camera or server known as the signal-processing unit. This unit rebuilds the electric impulses as usable data.

D. Display – Once translated, the usable data is sent to the display, where it is appears as a graphic rendition of the contrasting heat emissions that were originally captured. These images exist in the visible spectrum, allowing the human eye to see the subject via its own thermal energy.

Cooled or Uncooled – Most infrared cameras fall into the “uncooled” category, meaning that camera is not equipped with any kind of onboard cooling mechanism. Cryogenically cooled infrared cameras, on the other hand, are higher-end devices featuring a sophisticated cooling device. Although this variety of camera is considerably more expensive than the more common uncooled versions, it provides the camera with an extremely high level of sensitivity to thermal energy variations. This means that cryogenically cooled infrared CCTV cameras can receive a much finer range of information, resulting in images with much more detail and depth.

In the Dark – Because infrared CCTV cameras draw all of their images from a person or object’s level of infrared radiation, their performance and image quality is in no way affected by light. Whether covering an area engulfed in darkness or filled with blindingly bright lights and flares, an infrared CCTV camera will always perform at the same level.

Infrared CCTV Cameras needs a light to be able to capture images, however, this light is not visible to the human eye. The camera works in conjunction with LEDs (light emitting diodes) which provide the cameras light source. Once light levels drop below a certain level, the camera will illuminate the area with its own infrared LEDs. These LEDs are either built into the infrared camera, placed separately, or both; more LED emitters means more space illuminated and therefore a larger visible area at night. Various types of emitters are available and they operate at different frequencies which may cause them to emit a slight red/orange glow which is visible – the more you pay for high-quality emitters, the less obvious this glow will be. It is possible to buy emitters that operate at a frequency invisible to the human eye, but expect to pay more for the better technology.The images the CCTV captures are saved either to VHS or more commonly a hard drive, which you will then be able to view.

Closed circuit television. It is considered a revolutionary inventon when it comes to security. Due to its advantages it gained fame in no time. It is often used for security purposes in house, stores and banks etc. It keeps an eye on the visitors. It can also be used in schools to track the behaviour of a student. It has countless advantages, but that does not means that it is perfect.CCTV, or closed circuit television, is the most commonly used security system for homes, stores, banks and businesses. A CCTV system is made up of single or multiple cameras, a recording device and a monitor. Systems can be wired or wireless. While CCTV has many advantages, there are disadvantages in both types of system. There are different advantages of CCTV camera-

Limitations – A major disadvantage for CCTV cameras is that they can only monitor a limited area. Criminals can vandalize the cameras in various ways, such as sticking gum or spraying something on the lens. They may even be able to change the angle of the camera. Criticism from the general public is usually about the lack of privacy and high cost to install for personal use.

Wireless Systems – Wireless systems need a specified frequency for the camera to send signals to the receiving and recording station. Other electric motored products, such as air conditioning, fluorescent lighting and cordless telephones can cause interruptions in the frequencies, affecting the picture quality. Wireless systems are subject to distortion in image quality, and need experts in wireless technology to identify and repair system breakdowns. Some systems may not be completely wireless, as they require an electric power cable.

Wired Systems – Wired CCTV systems have the disadvantage of being fixed to a particular area, meaning the camera can’t simply change location. The installation and cabling of these cameras is a difficult task that demands the assistance of professionals.

Hacking – The value of CCTV information has increased, resulting in a higher risk from hackers. Hacking CCTV footage has led to privacy issues, such as images captured by CCTV of naked women distributed across the Internet. It is not possible to completely protect public security systems from hackers. As the system connects to a network, hackers can hack into the system virtually from outside locations.

The video of a CCTV can be hacked by a hacker easily. Suppose there is a CCTV installed near an ATM machine. So the hacker will hack the video of that camera and can easily get the pin code and any other information he wants about a customer or ATM user. Another disadvantage of CCTV is that not everyone can afford it. Despite all these disadvantages CCTV still allows you to secure your place to a great deal. It has disadvantages but as you know nothing is perfect.CCTV cameras are becoming increasingly affordable to install. Installation of CCTV surveillance systems is a one-time expense, as well: Instead of hiring multiple security officers to monitor several different areas of your establishment or town, a handful of officers can virtually “patrol” an area from a console that monitors a wide area, reducing manpower costs to provide the same level of security.

IP Cameras are increasingly becoming a necessary part of any home or business security system. Bad people need to know that they are being watched. That way, they are less likely to commit their heinous crimes. But sometimes bad guys will disable video cameras. What is to be done about that problem? Well, a bullet camera is one solution. Its small enough to be hidden in the palm of your hand or in very small crevices around your property. So the thugs may know theyre being watched, but they wont know from where. And these cameras work well even in low-light situations.

Better yet, the cameras no longer hook up to bulky, easy to steal, tape recorders. The new IP cameras stream your surveillance footage to anywhere on the earth that you want, and youll now have a permanent record of everything that happens on your property. Not sure if the hoodlums bothering you are the same ones who were at it five years ago? Just pull up the video on your computer. Or put together a shaming video of the highlights of idiots whove vandalized your store. Get your revenge the legal way by putting these criminals where they deserve to be.

Buying an IP camera in the UK makes a lot of sense. Why spend your precious pence on a camera from America (by way of China) when you can just have one from the UK?
