It seems to be a consistent thing, historically - technological progress takes massive leaps forwards during times of war, with new ideas being born even as human life is extinguished. Such was the case in Korea, where infrared cameras first gave US soldiers the advantage of sight in any conditions, along with the ability to sight enemy troops, hiding amidst the foliage in the trees above them. These days, aside from their military applications, these instruments are being put to use in any number of fields, from building inspection and astronomy to, you guessed it, home security surveillance. There's a fair amount of confusion regarding infrared security cameras, as many people erroneously associate the term with so-called 'night vision' security cameras. Night vision cameras utilize the World War II technology of night glasses, which use a large diameter objective along with numerous lenses to amplify light up to levels six or seven times greater than would normally be perceived by the human eye. Alternatively, some of them use so-called 'active infrared', whereby the camera is equipped with a torch which provides illumination just below the wavelength visible to the human eye, while the camera's lens is a CCD lens sensitive to light on this wavelength. Both these designs are known for producing images of inferior quality. Much of the time, the resultant footage is monochromatic, fuzzy and about as clear as the imagery you'd expect from a video game console in the 1980s. Enter the infrared security camera. This vastly more sophisticated machine makes us of a microbolometer, a device capable of detecting the black body radiation of objects. Black body radiation exists in direct proportion to the heat a creature or object produces, and thus can be viewed entirely regardless of any source of illumination. The imagery that results, while it ordinarily won't allow you to create a particularly detailed picture of the intruder, will help you to find things such as their body structure, gender, and where in your home they might have left fingerprint evidence. If you go the extra mile and get wireless infrared surveillance cameras, not only will you not have to bother with running wiring all over your house - you'll also be able to ensure that the footage captured by your home security surveillance system is beyond the reach of intruders, sent instantly off to a storage cluster or private website for later viewing. Thus you'll no doubt agree that wireless security cameras in general and infrared security cameras in particular can be a truly invaluable addition to any home security surveillance system. This is doubly the case for those living in homes with poor external lighting. Your main considerations when it comes to the question of whether or not to purchase one or multiple infrared security cameras will be twofold. The first question is: do you need them? In areas with good on-street-lighting, most areas outside of the house will be more suitable for a standard wireless surveillance camera. Furthermore, if you have (or take the trouble to install) motion-activated lighting around the house, the external infrared security cameras will really be quite redundant. Remember, great as they are, these can be very pricey toys. FLIR, the top producer of infrared security cameras, still prices its low-end models at no less than $2000 a piece. One truly wonderful thing about infrared security cameras is that, due to their ability to detect temperature changes, they not only beef up your home security surveillance system, but also completely eliminate the need for smoke detectors. You can simply have your cameras set up so as signal the fire department when the cameras detect that ambient temperature has gone over a certain level. This is something you should factor into your reasoning when debating the affordability of the technology. Read more about Infrared Security Cameras at my website : www.Home-Security-Pro.com.
