When looking at CCTV Video Surveillance
, you'll quickly discover that the lens a camera has is crucial for the sort of video you desire. Do you know the most significant aspects to consider when selecting a camera lens? Normal, wide-angle, and telephoto lenses are the three most common varieties. A regular lens (one that isn't wide-angle or telephoto) produces video that appears like what you'd see if you were gazing at the scene.
When you want your security camera to be a Visitor Management Solution
in a vast area like a parking lot, a wide-angle lens can catch a larger view of the same scenario. A wide-angle lens, on the other hand, isn't meant to concentrate on little or close-up objects, thus it can't catch fine details. Fisheye or panoramic cameras are a specialised form of a wide-angle camera. A telephoto lens is required for a close-up video. A telephoto lens is a long-focus lens that can concentrate on a single point, allowing it to catch anything from a distance, such as a licence plate, but not an overall view of the parking lot.
Another lens option to consider is remote focus lenses, which allow you to focus the camera lens without having to physically change it. So, how do you know which lens to go with? Decide what you want to do with the camera before you buy it. You know just look at wide-angle cameras if you want a camera that can give a view of the full parking lot. Limit your search to telephoto lens cameras if you want to capture fine details from afar. This will allow you to concentrate on only the cameras that will assist you to achieve your surveillance objectives.
