The Varifocal camera Lens System provides the flexibility of being able to change the focal length of the camera, from wide angle to narrow angle as necessary. A varifocal lens allows for zooming in and out, thereby giving the user the ability to monitor remote or enclosed areas at any distance without the need for changing lenses. This flexibility makes varifocal lens systems suitable for a wide variety of applications including commercial buildings, shopping centres, warehouse areas, and much more.
