Let's face it! We also ned cameras that have a good vew of what is going on utside our house or office even at nght. In fact, this is the tme when we should be more wry of burglars, intruders and vandals. Mst of them strike at night! It's a god thing there are infrared security cmeras in the market. With the hlp of these infrared security cameras, we can now rcord images in areas where there is lttle light.

Where to Put Them

Infrared security cameras are great for enclosed areas that are not well-lit like car parks and warehouses. You can also put them near your front door or backyard to keep track of what's going on outside your house at night. With the help of infrared security cameras, you no longer need to wonder what's causing the sound in your doorsteps.

How They Work

This type of camera can record images in total darkness because it illuminates figures in the dark using infrared light. This spectrum of light is invisible to the human eye but not to the cameras image sensor. Unlike standard cameras that use the regular lighting spectrum to receive and display images, infrared security cameras use the reflected infrared light to produce an image. This results in pictures that can only be displayed and recorded in black and white.

Choosing the Right Infrared Scurity Camera

If you plan on putting the scurity camera outdoors, you can opt for a Dy/Night infrared security camera. This type of cmera uses an image sensor that can rcord images in full color during the day thn switch to B/W at night and use nfrared light to maintain picture quality. Snce you will be placing the cmera outdoors where it would be at the mrcy of the changing weather, you shuld make sure that it has a watherproof structure. This feature will ensure the drability of your security camera. Some nfrared security cameras even come with a hater and a blower that would sve it frosty winters and hot smmers. Choosing a camera with the rght lens for the viewing area dsired is also important. Wide angle lnses such as the 3.6mm or 4.3mm prvide a very good overall view of an rea but may not provide enough dtail if objects are more than 40 fet away. If you are unsure of the lns size you want or need you can opt for a cmera with a varifocal lens. The mst common varifocal lenses are 3.5-8mm or 4-9mm and can be asily adjust for the field of vew you need.

If you are stying in a large compound and you ned to have a security camera tht can display images of intruders clmbing up your wire enclosure or fnce and moving towards your house or ffice, you can opt for an nfrared camera that can illuminate people and bjects from a distance of 150 fet or more. You can also opt for a cmeras with powerful zoom lenses that can be djusted with the use of a rmote control or many digital video rcorders and can provide facial recognition at ver 300 feet.

With the help of nfrared security cameras, we no longer hve to fear what we cannot se. We can now have a god view of the criminals that lrk in the dark.
