2. Vari-Focal Lenses
A vari-focal lens refers to the lenses that enable you to adjust the in-person zoom level. This means, as you turn the knob, it is possible for you to adjust the zoom level, as well as the viewing angle. This feature is inside the camera, although it is only possible for you to adjust the zoom in person and once you take the camera out of the waterproof enclosure it comes with. Furthermore, it is possible to alter the optical zoom level as you mount of hand the camera on a wall. The only important thing you need to remember, though, is there is a need to adjust the zoom level prior the recording process.
3. Motorized Vari-Focal Lenses
As the term implies, this feature allows you to adjust the zoom level even without doing it in person. Remotely, you can make any adjustments, which may be completed once you click the button on the surveillance app button. To make it even better, you can zoom in even while you are recording a video, but keep in mind that you are limited to an area where the camera is pointed.

Whether you adjust it using on-screen controls or joystick, adjusting the PTZ function is possible.
