Abstract

The infrared motion sensing device is mounted on a housing plate and is covered by a lens screen (16) that focusses incoming IR radiation. The screen is dome shaped and comprises an infrared transmitting material, such as polyethylene. The dome has two regions (24,25), with the upper one having a pattern of Fresnel lenses (27) formed. The lower section has a pattern of hemispherical lenses formed across the surface. The lenses focus onto the centrally mounted sensor.
