Infrared Security Camera System

A consumer will need to have an infrared security camera system installed to see in total darkness. There are many arrangements that a purchaser can buy to fulfill desired needs for surveillance. Much of the equipment bought for safety has illuminators built into the chassis. These units photograph in color in the day time and but change to black and white for night vision. Many units use LED (light emitting diodes) lighting, which is installed around the outside lens of the unit. It uses a light from a different region of the electromagnetic spectrum than humans normally use to see so they are invisible to the human eye. The low light captures the scene almost as clearly as if the photo were taken in the afternoon sunshine. Businesses have used this equipment with good results. Also available for those who cannot take the time to wire the equipment is a wireless infrared security camera. IR illuminators can be bought separately to apply to already installed products.

An infrared security camera system will work in color as long as the light upholds, but when sunset descends, the images turn into black and white. The built-in sensors turn on the LEDs and the cameras begin reading the LEDS. The level of light required to shoot good photographs is called the camera's lux. To calculate this reading, the lower the lux, the better the equipment can see in the dark. If the lux is 0.0, no light is needed at all to take photographs. The number of LEDs determine how far the product can see ahead in the dark. Also, when purchasing a wireless infrared security camera, remember that the size of the lens will determine the clarity of the pictures and the distance it can see ahead. Unlike earlier versions, at 940 nm, the hull of the machine will be invisible to the human eye even in total darkness. At 850nm, a slightly reddish or pinkish glow will shine through the dark. An "nm" is called the nanometer rating.

Although popular wisdom says otherwise, a wireless infrared security camera does not read the heat on objects it shoots. Instead, it sensors a type of light called infrared. Therefore, it requires its own light source. This light is independent of daylight and is not recognizable by the human eye. This light is either provided by the system itself or is provided by a separate enclosure. A reputable manufacturer will list its products' range and the angle of the beam. Some emitters produce an orange glow, but emitters can be purchased that produce only invisible light ranges. But this ability will cost more. The infrared security camera system can come in small sizes, like bullet cams, or larger sizes to allow for more IR cams. These systems are most amenable to areas that have little light but also are confined in area. Otherwise, low-light cams may be more desirable and effective. If the buyer has to purchase a number of IR cams to safeguard the property, it may be more cost effective to purchase low-light systems and take advantage of any light emitted in the area. Varifocal lenses are available on low-light systems. Therefore, low-light systems can take better advantage of the range of the lens whereas the IR systems must rely on the emission range of the special lighting.

For example, a 50mm lens with low-light could be set up to illuminate an entrance 100 feet from the product. The same distance with IR would pose a problem in that the IR lighting would limit the range before the range of the lens was exhausted. Therefore, 100 feet distance would be too far to get IR photographs. A large bank of IRs would have to be installed to complete the surveillance. On the other hand, if the desired surveillance is in a darkened area in which low-light would not function, then an infrared security camera system would be the best option. Also, sometimes a combination of IR and low-light can fit the property well. Most reputable lighting companies will help the consumer develop and install a plan for property surveillance that is cost effective and achieves the purpose. Some CCTV and DVR firms also offer do-it-yourself installation for those who have some knowledge of these processes. They will help the consumer determine which type of product will function best in the specified area.

Many manufacturers will put examples of what their product can do on their websites. Wireless infrared security camera can also be purchase in closed circuit television (CCTV), which enables the business owner to monitor and record the images taken by the CCTV. The product purchased can also grow with the business person's needs, so someone can purchase a basic plan with the idea of adding to it as the business expands or as other needs arise. The IRs are called day/night photographic equipment because they switch modes from day to night when the light changes. A built-in sensor tells when the light is too low for color pictures, and the pictures change to black and white, which is more effective at night. The sensors are built so that they will not trigger when cloud cover or other temporary light change may darken the area. The Bible tells us of God's care for us, "For thou art my lamp, O Lord: and the Lord will lighten my darkness," (2 Samuel 22:29). Just as God lights our lives, so we too can light up the darkest parts of our property with IR and prevent crime and have a record of the incidents that happen within our borders.
