Zoom Cameras Deliver 4K UHD Resolution

Lorex Technology’s motorized zoom lens security cameras, otherwise known as varifocal security cameras, are equipped with state-of-the-art lenses that are capable of easy field of view (FOV) adjustments. The cameras can zoom in on a narrow FOV to focus on specific object or area in its view, like a doorway or cash register, or zoom out to a wide FOV for maximum coverage, or anywhere in between. Cameras with a varifocal lens can zoom in and out, allowing users to customize the field of view.

 

To achieve a customizable field of view, the varifocal cameras use an optical zoom lens. This type of lens can move within the camera, altering the distance between itself and the image sensor. As a result, the further the lens moves from the sensor, the more magnified the field of view will become. Optical zooms do not degrade the quality of the video unlike a digital zoom, which basically just creates an "artificial" close-up by cropping up and magnifying (or blowing up) a portion of the image.

Lorex offers a wide range of zoom lens security cameras, in both bullet and dome varieties. The latest varifocal offerings are equipped with 4K Ultra HD resolution recording, a 4x optical zoom lens, and Color Night Vision. Zoom lenses can also be found in advanced PTZ (pan-tilt-zoom) security cameras, which can be programmed to use their 12x optical zoom capabilities as part of a set "tour" or "pattern." A new "Zoom and Focus" feature for varifocal PTZ cameras is also coming soon. This feature means that the camera will not only detect motion but will also automatically zoom in and focus on it.
