Motorized Varifocal Lenses
Photo to be provided by the client. No product or factory photo is shown on this page.
A motorized varifocal lens is a varifocal lens whose focal length adjustment is driven by a motor, rather than set by hand at the camera. This page covers that pairing for buyers who need the view to change without a visit to the camera.
The motor changes the practical meaning of varifocal adjustment. A hand-set varifocal lens is adjusted once, at installation, and then left. A motorized varifocal lens can be adjusted afterwards, from wherever the camera system is controlled, which suits cameras that are hard to reach, cameras whose view must change during use, and installations with many cameras.
What this pairing covers
This page discusses motorized varifocal adjustment as a buyer requirement. Availability from Hangzhou Ai Ke Electronics Co., Ltd. is not established. Ask whether a suitable lens is available before ordering. It does not describe a particular model, and it does not state how the motor is controlled, because control arrangements differ between camera systems and must be confirmed for the exact lens and system concerned.
Buyers who need adjustment only at installation should read the general varifocal page instead, where hand-set adjustment is the simpler assumption. Buyers who need adjustment during use should start here.
Where motorized varifocal lenses are used
Motorized varifocal lenses are used with CCTV cameras, security cameras and other cameras that are mounted out of reach, that watch scenes which change, or that must switch between an overview and a detail view during use. Examples include cameras over yards, halls, car parks and boundaries, where the point of interest moves.
They are also used in installations with many cameras, where visiting each camera to adjust it would be slow. In those cases the motor is not a luxury but the only practical way to keep views correct across the installation.
What to confirm before ordering
Confirm how the motor is controlled for the exact lens concerned, and confirm that the control arrangement works with the buyer's camera system. Confirm the model, specifications, minimum order quantity, lead time and price for the quantity required, and confirm compatibility.
Documents should be confirmed at the same time. Certificates available upon request. No certificate detail is stated on this site.
Frequently asked questions
How is a motorized varifocal lens different from a varifocal lens?
The adjustment is driven by a motor rather than set by hand, so the view can be changed without visiting the camera.
Do I need motorized adjustment?
Only if the view must change after installation or the camera is hard to reach. If the view is set once, a hand-set varifocal lens may be simpler.
How is the motor controlled?
That depends on the exact lens and camera system. Confirm the control arrangement for the lens offered before ordering.
