In this comprehensive blog, we will delve deeper into varifocal lenses, their uses, and the benefits they offer over fixed-lens cameras. Let’s start with understanding what a varifocal lens is and its properties.
What are Varifocal Lenses & Their Properties?
Varifocal lenses are a type of camera lens commonly used for security applications due to their adjustable focal length. In this, one can easily adjust the focal length, enabling a zoom-in and zoom-out feature to capture different fields of view. It can also be called a security camera lens, as its features are particularly useful when the distance to the subject may vary. Allowing easy coverage for wide-angle and close-up shots without the need to change camera positions. Due to its extraordinary features, its use is readily seen in facilities such as airports, hospitals, government offices, and warehouses.
These camera lenses typically offer an end-to-end range, covering a wide field of view. Their general lens sizes come in 2.8-12mm, 3.5-8mm, 6-60mm, and 5-10mm lenses. In this, the 2.8mm to 12mm allows capturing of a wide field of view or close-up details. While the extended size, like 4.5mm to 60mm, can capture long-distance surveillance, it allows easy capture of license plate numbers on vehicles from traffic. These indicate that the larger the aperture number, the more zoomed in the image will appear, allowing greater detail to be captured.
The CCTV camera lens allows features such as manual or motorized, allowing easy adjustments from on-site or even remotely. Their primary application lies in security applications. Thereby, the sector includes:
- Commercial Properties: For monitoring entrances, parking lots, and large retail spaces.
- Residential Security: In residential settings, it is used for home surveillance, allowing homeowners to adjust the camera view based on their needs.
- Public Spaces: Used in areas such as airports and government buildings, where flexible monitoring is crucial.

Another great benefit of a variable security camera lens is that it can capture images and videos with greater detail without distortion.

Therefore, zoom out as far as you can to capture a wide view of the surroundings, and the image quality will remain intact in both cases.
3. Future Proofing
The varifocal lenses are versatile, so they can be easily readjusted to fit any new environment, such as when shifting to a new house. These would have been an issue with any other camera or a fixed-lens camera, because they’re only set up once. After all the measurements and careful consideration of the angle view, coverage range, and many other factors.
4. Cost-Effective
The varifocal lenses also save a lot of money, as they cover large areas and allow zooming in and out simultaneously. These extensive properties eliminated the need for multiple camera installations, thereby saving significant money on cameras.
5. Less Installation Cost
When an individual wants to capture a different angle of view with a fixed lens, they have to reinstall it and move it. The reinstalling process involves relocation, drilling, and wiring, costing extra time, money, and energy. However, with a varifocal lens, all these reinstallation problems don’t exist, and the installation process becomes even easier if it’s Wi-Fi or PoE-enabled.
