Infrared cameras are getting more and more market share and become a common choice when selecting a security camera for a surveillance system. Let first understand whet are we dealing with from technology and functionality perspective. The need from infrared security camera arise when you need a camera for vary light, low light or low light environment. With a basic understanding of IR Camera technology that question becomes clearer.
The basic way to understand infrared camera is to describe their functionality as a camera with a flash light. The only different is that the light that produces by the flash light is not visible to the human eye. The stronger this flash light is the larger area its going to light up. For that reason all infrared camera comes with effective distance, which mean how strong is the infrared flash light is and how far area its going to reach. The infrared light in infrared security camera is not active all the time. During the day these camera produces crisp clear color picture, but when the light level drop below 1-2 Lux set level the camera IR light source kicks on and lights the space. The infrared light is produces by small led installed around the lens the more leds the stronger the light is and the larger the space can be lit up. A quality IR camera will list its effective range and angle of its IR beam.
IR cameras come in a variety of sizes and types. The sizes can range from small bullet cameras to larger more commercial look cameras.

Most Infrared security cameras are IP66 Indoor / Outdoor and water proof, so you can easily install them indoor or out door environment
If large area must be covered with IR technology it can be done by using IR illuminator which are basically large infrared flash light.
