Advantages and characteristics of lens

Day & Night

With special design, IR series lenses make the portrait aberration lowest, and the focal planes for the visible and infrared light ranges almost the same, which means that the surveillance camera can deliver sharp images in both day and night applications.


Flat Image

With the use of advanced optical design technology, our lenses can get high definition and high contrast performance over the entire image field, from the center to the periphery. Also, these lenses are the most suitable for the image cut-out function of IP cameras.

Multi Coating

To minimize double image and flare present in backlight, multi coating is adhered to the lens surface. Hence, the lenses can show high contrast resolution performance even in backlight.

High resolution lens

The pixels of Forecam high resolution lenses are beyond 3.0 Megapixel

Camera lens is the key to affect the image quality, if poor lens quality, naturally difficult to capture a clear picture. "Optical lens should meet clear imaging, light transmittance strong, evenly distributed illumination image plane, a small image distortion, adjustable aperture and other requirements.
