Only the right people. Only at the right time.
Do Link supplies and installs biometric terminals, networked door controllers, turnstile gates, and attendance management systems — from a single door to a multi-building campus with thousands of users.
Choose the credential that fits your security level.
Every terminal we install supports multiple authentication modes — combine them for multi-factor entry or deploy a single method for speed and simplicity.
Fingerprint
Fast local recognition, 3,000+ user capacity. FAR < 0.0001%, works fully offline. No network required to grant access.
3D Face Recognition
Liveness detection prevents photo spoofing. Works with masks. Up to 30,000 faces, sub-0.2 second recognition. Temperature screening optional.
RFID Card
Proximity Mifare 13.56 MHz or EM 125 kHz. Wiegand 26/34 output — compatible with virtually all access controllers on the market.
QR Code
Visitor management via smartphone or printed QR. Temporary or one-time-use access. No physical credential needed — ideal for controlled visitor flows.
Finger Vein
Reads the vein pattern beneath the finger's surface — impossible to duplicate. Used in banks, data centres, and high-security labs where fingerprint spoofing is a concern.
Palm Recognition
Contactless palm-vein or palm-geometry scan. Fast throughput for high-traffic entry. Hygienic — suitable for hospitals, clean rooms, and food production.
Control pedestrian flow at every entrance type.
From a single office door to a high-security turnstile corridor — we match the gate to the throughput, risk level, and site aesthetics.

- 2.2 m full height
- Cannot climb or bypass
- Bidirectional control
- Motorised or manual

Access control does not stand alone.
Linked CCTV Events
A forced door, held-open alarm, or failed credential automatically triggers the nearest CCTV camera to record and push an alert — one event, full visual evidence.
Attendance Management
Every door tap or face scan is logged with user ID, timestamp, and location. Reports export to Excel or payroll software for shift tracking, overtime, and absence management.
Vehicle Barrier Link
Connect pedestrian access control with barrier gate systems on the same site. One management console, one credential database — consistent access policy for people and vehicles.
