A varifocal lens is a security camera lens used to change the focal length, zoom, and field of view without losing focus. This differs from a fixed lens because, unlike fixed lenses, which usually have a fixed angle of view, it allows adjustments in manual or automatic zoom mode for zooming in and out.
One of the greatest benefits you get from using this lens is the ability to zoom in and view detailed scenes. A single CCTV camera varifocal Lens is capable of covering large open areas and zooming in on certain areas when needed. This is particularly useful in locations where security threats may change, and different levels of monitoring are required. For example, a retail store may need a wide-angle view to monitor customers but require zoomed-in footage near cash registers for detailed observation.
The quality of security footage suffers due to poor lighting conditions; this lens overcomes such problems. Many modern lenses with varifocal features come with an auto-iris feature; this feature automatically adjusts the amount of light entering the lens. This will ensure that the camera will capture high-quality video when monitoring an outdoor space at night and when monitoring a lobby during the day.
The proper choice of lens improves the efficiency of any security system. Using the right technology, security teams can change the focus and observe locations better. Superior CCTV offers high-quality security solutions to meet surveillance needs.
