| 1 / 2.8 "Sony Exmor IMX291 sensor with STARLIGHT technology. Low brightness, visibility at 0.0001Lux, color vision even in night mode With the addition of the STARVIS feature we have significant advantages: - Backlit structure with 2.9 µm-square unit pixels - High sensitivity (two or more times greater than other products on the market) - Increased sensitivity in the vicinity of an area covered by infrared light - Supports WDR (WDR multiple exposure, DOL-WDR) - Versatile interface (parallel CMOS, low voltage LVDS serial, MIPI CSI-2) With the Sony CMOS sensor it is possible to have color shots even in night mode. Normally, when entering night mode, the color vision becomes black / white.
With the SENSOR present, night shots will be sharp and in color |

ULTRA WDR up to 120dB WDR (Wide Dynamic Range): It is the professional solution in cases where it is necessary to operate in conditions of high light / shadow contrast. Fundamental in the case of shots from the inside out, license plates, shaded spots or all situations where there is no homogeneity of light. The higher the db value, the greater the camera's ability to manage the strong difference in the backlight present. Common WDRs usually reach 80db, the human eye is able to recognize a difference of up to 100db. This model reaches up to 120db while managing very strong contrast levels. ![]() |
![]() | HLC (High Light Compensation) allows greater light management, in the presence of direct light (cars, torches, etc ...). It also prevents attempts to blur the image. ![]() |
![]() | Allows you to adapt the lens to Night / Day vision |
![]() | The IR CUT FILTER is a mechanical filter that allows a correct display of images in daylight viewing conditions. It filters the typical infrared frequencies thus improving the image quality. In night conditions the filter is removed as it is necessary to capture the typical IR frequencies. ![]() |
![]() | BLC (Back Light Compensation) is one of the 3 possible Steps in managing images with Contrast, typical situations are (Entering or exiting car parks, Plaques, Particular lights, Entrances with shots from inside to outside, etc.) the compensation of light is one of the most complex operations possible, the BLC function allows a discreet adaptation to these situations |
![]() | AGC is an integrated signal amplifier that allows vision even in critical conditions. It is automatic and does not require specific settings. |
