Face Recognition Door Lock

Yes. Kaadas face recognition locks use advanced 3D infrared depth mapping, not a standard 2D camera to verify your identity. This technology is designed to resist spoofing attempts such as photographs, video recordings, or masks. All biometric data is processed and encrypted locally on the device and never uploaded to external servers.

No. Kaadas face recognition models use 3D structured-light or infrared sensing to build a depth map of your face. Unlike older 2D camera-based systems, this technology actively measures facial depth and is highly resistant to spoofing by flat photos, screens, or printed images.

Yes. Kaadas face recognition locks use infrared (IR) illumination, which operates entirely independently of visible light. The lock reliably identifies users in poorly lit corridors, late at night, or under any low-light condition — exactly the environment found at most HDB and condo main door entrances in Singapore

 Prescription glasses generally do not affect recognition accuracy. Sunglasses with highly reflective lenses and face masks covering the nose and mouth may reduce reliability on some models. All Kaadas face recognition locks include fingerprint, PIN code, RFID card, and mechanical key backups, so you are never locked out regardless of what you are wearing.

Face recognition is completely hands-free, no need to touch any sensor. It works even with worn, dry, or damaged fingertips, and has no finger-placement sensitivity. Fingerprint locks require deliberate sensor contact and can struggle with wet or calloused fingers. Both are highly secure, but face recognition offers the most effortless daily experience.

For households that value touchless convenience and the highest level of biometric security, face recognition offers daily benefits that go beyond standard fingerprint models. It is especially worthwhile for families with young children, elderly residents who struggle with PIN codes, and anyone who regularly arrives home with both hands occupied.

Storage capacity varies by model. Most Kaadas face recognition locks support multiple user profiles, accommodating all typical household members including family and live-in helpers. Please check the individual product specification page for exact capacity figures for each model.

All Kaadas face recognition locks are equipped with multiple backup access methods: fingerprint recognition, PIN code, RFID card, and mechanical key override. If facial recognition fails for any reason, whether due to lighting, appearance changes, or battery issues, you can always enter using one of these alternatives.

Yes. Kaadas face recognition door locks are designed for compatibility with standard wooden doors in Singapore HDB flats and condominiums. Your door must be at least 40mm thick. Our installation team assesses your specific door configuration prior to fitting to ensure a safe and compliant installation.

Yes. All Kaadas digital locks purchased through kaadassg.com include free delivery and professional installation in Singapore. After your order, our team will contact you to schedule the installation. Technicians will configure your facial profiles, PIN codes, and walk you through all features on-site.

Both are premium biometrics. Face recognition is entirely contactless, the most hands-free option. Vein recognition (available in the Kaadas Q9) scans internal vein patterns inside your finger using near-infrared light, which are impossible to replicate from the outside. If you want both technologies in one lock, the Kaadas Q9 supports finger vein, face, fingerprint, Wi-Fi, PIN, card, and key.

Kaadas face recognition models use a rechargeable lithium battery rather than standard alkaline batteries. Battery life depends on usage frequency. The lock provides a low-battery warning in advance. An emergency external power terminal also lets you connect a portable battery pack if the internal battery is fully depleted, so you are never locked out due to power.
