3 Terms and definitions

The following terms and definitions as defined in GB/T 20145-2006 apply to this document.

3.1 Video surveillance system active lighting components

Fill light

A fill light device for enhancing the effect of a video surveillance camera capturing an image.

Note 1. The fill light in this standard includes products integrated with video surveillance cameras and independent of video surveillance cameras.

Note 2. The fill light in this standard has two modes of operation. pulse emission and continuous emission. Their corresponding fill lights are called pulse fill light and continuous emission.

Fill light.

3.2 Reachable emission limit

AEL The maximum possible light emission allowed within the specified category.

3.3 Up to light emission

Under reasonable and foreseeable conditions of use, the human eye may be exposed to light radiation from a fill light.

Note. The available light emission can be compared to the emission limit to determine the hazard category of the fill light.

3.4 Opposite angle angularsubtense

The angle of view produced by the source of the view at the observer's eye or measurement point.
