G. Leff Security Systems
Access Control Solution

Biometric Access
Control

Keys get lost. Cards get shared. Biometrics don't. Control exactly who enters your building with fingerprint scanners, facial recognition, and mobile credentials — backed by a complete audit trail of every entry and exit.

Core Features

Identity-Based Security

Multiple authentication methods working together to create layers of protection that credentials alone can never match.

Facial Recognition

Advanced 3D facial mapping identifies authorized personnel in under 0.5 seconds, even in low-light conditions. Anti-spoofing technology prevents photo or video bypass attempts.

Fingerprint Scanning

Multi-spectral fingerprint readers capture sub-dermal patterns for unmatched accuracy. Handles wet, dry, or worn fingerprints with 99.9% recognition rates.

Mobile Credentials

Turn any smartphone into a secure access key with encrypted Bluetooth and NFC credentials. Issue, revoke, or schedule access permissions remotely in real time.

Complete Audit Trails

Every entry and exit is logged with timestamp, identity, and location data. Generate compliance reports, track occupancy, and investigate incidents with searchable records.

Frequently Asked Questions

What is the difference between card access and biometric access control?
Card access uses key cards or fobs to unlock doors, while biometric access uses unique physical traits like fingerprints or facial recognition. Biometrics are more secure because credentials can't be lost, shared, or cloned. G. Leff Security installs both types and often combines them for multi-factor authentication in high-security buildings.
Who is the largest Dormakaba distributor in the tristate area?
G. Leff Security Systems is the largest Dormakaba distributor in the tristate area, with 16 years of certification. Dormakaba is a global leader in access control and security solutions, and G. Leff has been their trusted partner for installation and service across New Jersey, New York, and the East Coast.
Can access control systems use mobile phones instead of key cards?
Yes, modern access control systems support mobile credentials through smartphone apps. Residents or employees can unlock doors using Bluetooth or NFC on their phones. G. Leff Security installs mobile-ready systems from Dormakaba, Brivo, and Nedap that support both traditional cards and mobile credentials.
