Infrared cameras record clear images when there is no light. Some infrared security cameras have the option to switch between infrared mode and non-infrared color mode. This feature is ideal when you want the camera to work for both light and non-light operations.
Many infrared cameras in the market can record full-color images during daytime or when there is sufficient lighting. The camera then gradually switches to B/W in low light conditions to keep up a high image quality. This is the reason infrared security cameras are also known as day/night cameras. Infrared cameras have infrared LEDs that start working when it gets dark and can give a black and white picture in pitch black conditions. An infrared security camera is great for indoor and outdoor monitoring.
What You Should Look at When Choosing an Infrared Security Camera
When buying a night vision camera you should consider the size of the lens (such as 6 mm, and 8 mm), the camera sensor and the infrared distance. Cameras with a higher resolution have a better image quality but this is not the only thing that you should look for. The lens size determines your viewing angle and the field of view. The size and the number of the LEDs along with the lens determine the distance that you can see when it’s completely dark.
You should also look at the infrared distance ratings, this is the greatest distance that light can be shed on an object. Just like any other source of light, the further the object is from the light source, the less light that will reach it. For example, if you want to see someone who is 70 feet away, you should buy an infrared security camera with a rating of 80 or more.
Not all infrared security cameras are the same when natural elements are involved. The International Protection Rating or the IP Code is a rating that shows the level of protection that a device has from natural elements. Many cameras do not have this information clearly displayed but ideally, your camera should have an IP66 rating or higher, this means that your camera can handle extreme weather.
When it comes to selecting a camera based on the size of the lens it depends on the area that you want to concentrate on. For example, if you’re monitoring an area that is 20 to 30 feet then a camera with a 3.6 mm to 4.3mm lens can do the job perfectly. People and objects that are further away will appear smaller and harder to see. If you want to check an area that is 30 to 50 feet away and see facial details, then you should choose a 6mm to 8mm lens. Infrared cameras that are fitted with a varifocal lens allow you to adjust the size of the lens. Remember that the larger the size of the lens for a specific distance the more details you will see but the field of view will be smaller.
