Types Of Surveillance Camera Lens You May Find

There are generally three types of lenses - normal, wide angle, and telephoto. A normal lens (one that isn't wide angle or telephoto) captures video that looks similar to what you would see looking at the scene. A wide angle lens can capture a larger view of the same scene, a great option for when you want your surveillance camera to monitor general activity in a large area like a parking lot. A wide angle lens can't capture fine details, however, because it's not designed to focus in on small or close-up objects. One specialized type of wide-angle cameras is fisheye or panoramic. For a close-up video, you'll want a telephoto lens. A telephoto lens is a long-focus lens, and will be able to focus on one specific area; this allows it to capture something, say a license plate, from a distance but will not provide an over-all view of the parking lot .Another lens option to pay attention to are remote focus lenses - this will allow you to automatically focus the camera lens without physically adjusting it.

Before purchasing the camera, decide what you want to do with it. If you want a camera that can provide a view of the entire parking lot, you know to only look at wide angle cameras. If you want to capture fine details from a distance, limit your search to telephoto lens cameras. This will help you focus on only the cameras that will meet your surveillance goals.
