When looking to change the lens of your outdoor security camera, it is important to know what type of lens mount your camera uses. There are two main types of lens mounts and they look the same to most people. If you can't seem to get the camera to focus after changing the lens, then you probably got the wrong type of lens for your security camera.
The only thing that differentiates the two is the distance between the lens and the sensor once the lens is in place inside the security camera. With the C-mount, the distance between the lens and the sensors needs to be 17.526mm whereas the distance between the lens and the sensors needs to be 12.5mm in the CS-mount.
With what is typically called a C/CS adapter ring, which is just a 5 mm spacer used to make up the difference in spacing, it is possible to fit a C-mount lens over a CS-mount camera, but not the other way around. Focus is especially important for high-stakes outdoor security cameras that need to recognize faces or detail so make sure you get the right one.
