S5 - Vein Recognition Smart Lock
The BTRtec S5 is a keyless entry door lock built around finger-vein recognition, which reads the vein pattern beneath the skin rather than the surface of the finger. It works reliably for worn, cold, or small fingers that a standard fingerprint sensor can struggle with, and it starts at $750 CAD with professional installation included.

FAQ
Why choose vein recognition over fingerprint on a door lock?
Vein recognition reads the pattern beneath the skin using near-infrared light, so it is not affected by wet, cold, dirty, or worn fingers the way a surface fingerprint sensor can be. It also cannot be lifted from a surface the way a fingerprint can, making it the most secure biometric method BTRtec offers.
How long does the S5 battery last on a single charge?
The S5 uses a large-capacity 5,000 mAh lithium battery rated for over 10 months of use on a single charge, and it sends a low-battery alert before it runs out so charging can be planned ahead.
Does the S5 work for elderly parents or young children?
Yes. Vein recognition is designed to read reliably across a wide range of finger sizes and skin conditions, which is why households with older parents or young children often choose the S5 over a fingerprint-only lock.
