IR Cemras are increasingly becoming more popular by the day. The reason for the this popularity are dropping prices, more choice and ready availability. Choosing a good IR Camera for a particular site may pose a tough question in the minds of puchaser. Here is nitty grityy of what you essentially need to know:
1.) How far out will the camera need to see? Most IR cameras are specified at being able to see a certain distance in the dark. If you are wanting to see a 100ft out in the distance be sure the camera is rated for that distance more so check out a demo video footage for the same.
2.) Some camera placements can cause viewing issues if you go with an IR camera that is to powerful for the area needed. If the cameras is going in a small room or even outside looking in a small fenced in or partitioned off area. If you place an IR camera that has a illumination range or 100ft in an area that is only 10-15ft in length the light has the potential to reflect off of any walls or objects and can cause the camera to have a white glare in the image leading to distortion.
3.) Is IR always the answer? No, let’s say the camera is going in a bar or a low lit restaurant that has a very, you may find that there is not enough light to provide the IR camera with the ability to stay in day mode, but the area may have more light than what is needed to truly be in a night mode. The best recommendation for this setup would be a camera with a really low lux level and great light adjustment features.
4.) The lens also plays a major role in picture clarity during dark. A 3.6mm lens usually teands to leave a white circle in the image and this circle vanishes as the lens is increased to 6 mm. Decide your camera lens according to your requirement.
