Technology — three biometrics, one firmware family on InspirePulse — Smart Locks

3D face recognition — InspirePulse technology

A 2D camera fails when corridor light changes. The module projects a structured-light pattern and measures depth, so it works at night with IR fill, in backlight, and against a photo held to the lens.

What it changes in practice

Depth-based liveness — rejects photos and screens
IR illumination for dark landings
Sub-second match at 0.5–1.2 m
2 MP cat-eye in the same aperture

Honest limit: the silicon may be rated wider than the assembled lock. The cell and the display set the real range, which is why the face platforms are published at −20 °C to +40 °C.

508 DPI fingerprint sensing — InspirePulse technology

The sensor that carries most of the volume. A semiconductor sensor reads the ridge pattern rather than an image of it — the difference between a dry winter finger and a failure.

What it changes in practice

360° read angle
250 credentials per lock
FAR ≤0.0001 %, FRR ≤0.1 %
Anti-static, scratch-resistant coating

Honest limit: the silicon may be rated wider than the assembled lock. The cell and the display set the real range, which is why the face platforms are published at −20 °C to +40 °C.

Palm vein biometrics — InspirePulse technology

Fingerprints wear out: cleaners, farmers, bricklayers and anyone over 65 with thin skin. Palm vein reads haemoglobin under the surface, so dust, dryness and a thin glove do not interfere.

What it changes in practice

Tencent AI palm-vein + palm-print
Works wet or dry
Non-contact, hygienic for shared buildings
Paired with 3D face

Honest limit: the silicon may be rated wider than the assembled lock. The cell and the display set the real range, which is why the face platforms are published at −20 °C to +40 °C.
