CleanView™ Hydrophobic Dome Coating

The CleanView™ coating improves visibility by reducing water spots, dust and grease build-up on the camera dome housing’s glass. The CleanView™ coating treatment will allow the liquid to roll off of the dome’s glass surfaces when tilted vertically up to 10° or less. The CleanView™ coating leaves the camera dome’s glass clean, repels dust and grease, preventing IR reflections due to dust and smudges.

Smart IR™

Smart IR™ adjusts the image for IR cameras to prevent excessive illumination on objects that are in the front of the scene and offers a clear image in B/W without any loss of detail.

True Wide Dynamic Range (WDR)

Cameras with True Wide Dynamic Range (WDR) technology have advanced sensors that can process a wider range of lighting, dark and bright in the same image.
