Scene illumination approximate ranges

The Analytics system performance and accuracy are directly influenced by the quality and consistency of input data. Scene illumination is a key factor in this regard.

Illumination of an object is a dynamic parameter that varies depending on multiple factors, including:

Time of day (daylight, twilight, night)
Weather conditions (clear, overcast, rainy)
Artificial lighting (lamps switched on/off, car headlights)
Reflective surfaces and shadows

Approximate illumination assessment

For initial analysis and equipment configuration, refer to the table below. It provides approximate illumination values (lux, lx) for common scenarios. These values allow you to estimate brightness ranges and plan measures to stabilize and enhance video streaming.

Illumination conditions	Typical lux
Clear, sunny day	More than 100 000 lux (sun angle 55°)
Sunny day with slight overcast	70 000 lux
Overcast day	20 000 lux
Early morning	500 lux
Twilight	4 lux
Clear night, full moon	0.2 lux
Clear night with a moon in any phase other than the full moon	0.02 lux
Night, moon in clouds	0.007 lux
Clear night (no moon)	0.001 lux
Night with slight overcast (no moon)	0.0007 lux
Dark, cloudy night	0.00005 lux
Indoors, no windows, with artificial illumination	100 – 200 lux
Well-illuminated indoor spaces, offices	200 – 1000 lux
