A clean, game-ready 3D model of a motion detector (PIR sensor), originally modeled for Roblox and exported as a GLB/GLTF 2.0 file. Ideal for security scenes, surveillance environments, escape rooms, horror games, sci-fi corridors, office buildings, or any interior level design project requiring realistic safety hardware.

This prop faithfully reproduces the classic wall-mounted motion sensor formf actor - the rounded plastic housing with a fresnel lens dome typical of passive infrared detectors found in homes, offices, and retail spaces worldwide.

Free to download and use. No attribution required. Great for hobbyists, game developers, educators, and 3D artists building scene assets.

Low-poly optimized with under 2 500 triangles - perfectly suited for real-time
