With four different types of irises to choose from, you can pick the IP camera best suited to your surveillance needs.Īre you recording in an office building, and only during working hours? A fixed or manual iris will work well with the consistent light from overhead lights because they won’t need to adjust to changing light levels. Cameras with a P iris are also more expensive than models with fixed or manual irises, but the cameras are better suited for recording in locations where light is constantly and quickly changing.The amount that the iris can close is limited, preventing the blurred video that can occur when an auto iris overcorrects for bright lights.
What is video controller software#
On a fixed iris, the opening that allows light into the camera cannot be adjusted.Each of the four types of camera irises works slightly differently, so you can pick the one that’s best for you. Too much light can wash out your video, and too little light can make everything dark, so it’s important to have an iris that’s specifically suited for your camera’s location. The iris works by limiting the amount of light that hits the image sensor. When it comes to IP surveillance videos, you have several different styles of camera irises to choose from: a fixed iris, a manual iris, an auto iris, and a P iris. The light that the iris allows through hits the image sensor and that light gets recorded as electrical impulses that create the video. If the iris creates a larger opening, more light can get through a smaller opening allows less light through. A camera iris is the part of the camera that controls how much light comes through the lens.
