Outdoor Long Range Infrared Night Vision Cameras to Protect Your Home

When you hear something outside your home at night, and are trying to determine the cause, the automatic thing to do is usually to turn on lights and peek through the blinds. Unfortunately, this method of checking outside, albeit the most common, actually just lets whomever is outside see you. There is a much better method of being able to see exactly who is outside your home at night, even if it is completely pitch black. Using specially designed outdoor Infrared night vision security cameras, can provide you with a clear video feed of what is happening, so that you can safely watch your home and alert authorities if needed, without letting on your position to anyone who is outside.

Long Range Infrared night vision cameras employ infrared style LEDs or arrays that will illuminate the area in front of the camera with an invisible infrared light. This light is not visible to the human eye, but is visible to the image sensor of the camera. IR light will allow the camera to see in black and white during the nighttime hours, so that the camera can clearly see everything that is happening. Long range versions of these infrared night vision cameras can even deliver IR light that can be seen by the camera up to 100, 150 or 200 feet away from the camera. These cameras have more powerful IR LEDs for greater illumination, and often have lower light image sensors as well.

When selecting a long-range night vision security camera, it is important to understand that the range of the camera is rated by the distance under ideal conditions that the IR light will reflect back to the camera and provide a picture. At 72° F with 0% humidity, the rated distance will be the distance that the IR light will stop reflecting back to the camera. In order to deliver the best picture quality and clarity, it is highly recommended to keep the object being viewed between 60-80% of the maximum rated infrared range. This will help to compensate for changes in temperature and humidity and still deliver a good picture quality at night.

Another consideration to keep in mind when you are selecting a night vision camera, is the lens that will be used. Having a long range infrared camera will not really help you if the camera has a fixed lens that is a wide angle view. This is because even though the camera may be rated at 100' or more for IR light, that rating does not say anything about how large something will appear on the screen. With a wide angle lens at that distance, items on the screen will be very small and therefore almost impossible to distinguish. That is why many of the better quality Long-Range IR cameras will come with what is called a varifocal lens. These lenses have the ability to adjust the zoom and focus of the camera, allowing you to custom-tailor the width of view as desired to provide the best distinguishing characteristics.
