Varifocal Camera
A vari-focal camera is one that has been specifically designed to operate at various focal distances. These types of cameras differ from fixed lens cameras, which simply feature a lens that cannot be adjusted. We often recommend vari-focal cameras to our customers, particularly those who are uncertain of the distance and viewing angles that they wish to capture in surveillance footage.
Vari-Focal Camera Viewing Lengths
Vari-focal cameras can typically be adjusted to accommodate viewing lengths from between 2.5 mm to 10 mm, which offers a lot more range than cameras with a fixed lens. A vari-focal camera can best be compared to a zoom camera feature which can be manually adjusted. When using a vari-focal surveillance camera, homeowners have the option of selecting a high millimeter setting for narrow viewing fields or a low millimeter setting for wider viewing fields.
Vari-Focal Cameras Offer the Best Recording Flexibility
When selecting a security camera to monitor a home or a business, it is important to have an idea of the field of view that a camera will need to have in order to be the most effective.
The clarity and the focus of the images that the camera captures are also very important considerations. Cameras with a vari-focal lense allow owners to adjust settings in order to arrive at one best suited for the area being surveilled, as well as to capture the clarity needed to clearly identify the fine details of what has been recorded.
A vari-focal feature further comes in handy if a homeowner ever has cause to relocate a camera or simply feels the need to adjust a camera’s focus for whatever reason. In short, these cameras offer the most in terms of all-around surveillance flexibility.
Who Should Use a Vari-Focal Camera?
Those who are unsure about the exact field of view needed, those who may need to occasionally change a field of view or homeowners who plan to someday relocate a camera are advised to purchase a camera with a vari-focal lens.
While this type of camera can cost a bit more than a fixed lens camera, most customers find value in the variety and flexibility of a vari-focal surveillance camera lens over the permanence inherent in a fixed-lens camera. As with other surveillance and security tools, vari-focal cameras can be self-installed and can be used with other home protection devices to increase the overall security of a home or business.
