Security cameras are only as good as what they can see. After all thier entire purpose is to record video, so the better the video quality the more effective the security coverage.

The best way to improve the visual imagery of existing cameras is to use better quality optical elements. These will offer better contrast over all imagery, and fewer colour fringes around object’s edges (chromatic aberration).

With the better resolution high quality lenses provide, tiny details will be clearer and brighter. Especially at the edges of the image where all lenses have imperfections, also straight lines will show less curvature (geometric distortion).

‘Aspherical’ optics are particularly finely crafted to maximize light transmission, hence impressive F0.8 capabilities. Infrared in daylight and electric light can focus in a different place to visible light thereby defocusing your image. IR-corrected lenses reduce this effect.

A good camera should have a good quality lens.
