The Camcamp DL04 Palm Vein Smart Lock brings biometrics to residential access control by incorporating advanced palm vein scanning alongside traditional keyless entry methods.

Unlike standard fingerprint readers that scan surface skin prints, palm vein technology reads the unique vascular patterns beneath the skin, offering a significantly higher level of security that is virtually impossible to duplicate or spoof.

Designed as a complete front door handle set, the unit combines keyless security with an integrated video doorbell system.
