A home security camera usually can see in a range between 0 to 70 feet depending on the resolution, sensor and lens it's using. However, there are also professional cameras such as high-resolution PTZs that can see further away, with a distance that varies from 0 to 700 feet.
With an adjustable lens, varifocal cameras allow you to adjust until you have the perfect field of view. Unlike a pan tilt zoom models, this adaptability is used for installation only. Once your field of view is set, it stays the same, until it is adjusted.
How Different Focal Lengths Compare
| Lens Focal Length | Angle of View | Identification Distance |
|---|
| 50mm | 7° | 230ft |
| 22mm | 16° | 80ft |
| 12mm | 30° | 50ft |
| 8mm | 42° | 40ft |
A varifocal lens is a camera lens with variable focal length in which focus changes as focal length (and magnification) changes, as compared to a parfocal ("true") zoom lens, which remains in focus as the lens zooms (focal length and magnification change).
IP Security Cameras with Motorized Optical Zoom: IP or Wi-Fi cameras with motorized zoom allow you to adjust the zoom level of your security cameras remotely from anywhere you are. Zoom in and out with the provided on-screen controls on your security surveillance smartphone app or client software.
Varifocal lenses are sometimes referred to as progressive lenses, but they are actually the same type of lens. This alternative name comes from the progressively increasing/decreasing focal capacity of this lens type.
A zoom lens is a type of camera lens that offers the photographer a useful range of different focal lengths in a single lens. This is in comparison to a prime lens, which only offers a single focal length. A zoom lens allows for quick and easy re-framing of a scene while staying in the same physical position.
A CCTV security camera that has a fixed lens is permanently set, meaning that its angle of view, focal length and level of zoom cannot be changed. PTZ Cameras are an example of a popular camera form that include a varifocal, motorised lens.
With fixed lenses, you learn what fits in your picture without having to look through the camera. You can start composing deliberately as you're walking around. Fixed lenses get us moving around, and let us see better because we already know what will fit in our frame.
Varifocal lenses allow you to see at any distance, because they have different sections for viewing close up and far away and everything in between. So whether you're driving, using a computer, shopping or reading, you can wear one pair of varifocals to accommodate all your vision needs.
Standard Varifocal lenses are the 'entry-level' varifocal options and are chosen as an enhanced alternative to bifocals. They have clear vision and fairly wide focal areas for distance, reading and 'in-between'.
The varifocal lens is a light, compact manual iris lens, with an aperture equal to F1. 6. The lens can be used to control the iris for fine tuning e.g. against flicker problems in fluorescent illumination.
