How to Measure Field of View

Field of View (FOV) defines the horizontal angular range where the integration actively tracks the sun. Outside this range the sun is treated as "not in front of the window" and the cover returns to the default position.

Measurement steps:

1. Stand at the centre of the window, inside your room, looking straight out (perpendicular to the wall — this is the azimuth direction).
2. Look left: find the furthest point where direct sunlight can enter through the window without being blocked by a wall, pillar, overhang, or neighbouring building. Estimate the angle between straight-ahead and that point. That is FOV Left.
3. Repeat looking right for FOV Right.
4. A smartphone protractor app (or a simple protractor held flat) makes this easier to measure accurately.

Recommended values by situation:

Situation	FOV Left / Right
Standard window, no obstructions	45° each side
Wide window or sliding glass door	60–75° each side
Narrow window or recessed into a thick wall	30° each side
Protecting furniture or artwork from any direct sun	Measure actual unobstructed angle (see below)

Protecting fragile furniture or artwork: The default 90° per side (180° total) is intentionally wide to work for most installations. However, if your goal is to prevent any direct sunlight from reaching a specific area, use the actual unobstructed angle your window allows — not the default. Measure from the window centre to the edge of whichever wall, column, or frame first blocks direct sun on each side. A tighter FOV means the blind engages as soon as direct sun could enter, and stays in the default (typically more closed) position at all other times.

Example: A south-facing window set into a 60 cm thick wall may only allow direct sun within ±40° of perpendicular. Setting FOV Left and FOV Right to 40° each ensures the blind is always active during those hours, rather than the wider 90° default which would leave gaps.
