"Offers futuristic palm vein scanning in a physically average, budget-friendly package."
The 'Advanced Biometric Unlock' uses an infrared scanner to read the unique vein pattern in your palm, a method less susceptible to surface dirt, moisture, or wear than a typical fingerprint reader.
This lock is for tech enthusiasts on a strict budget who want novel biometric entry for an interior door or a front door fully protected from weather. The value proposition is in the feature set, not the physical security.
Anyone needing robust physical security should seek a BHMA Grade 2 or Grade 1 lock. If your door is exposed to direct rain or extreme temperatures, the IP53 rating is insufficient and will likely lead to failure.
