Reasons to buy

  • Dual-sided access authentication: Requires valid biometric or passcode verification to both enter and exit, providing maximum control for pool gates and perimeter fences.

  • High-capacity biometrics: Stores up to 100 fingerprints per side with self-learning scanner technology for quick access.
