Modern systems use keycards, fingerprints, face recognition, or mobile credentials to replace traditional keys, providing better security and audit trails for offices, factories, and commercial buildings.
What is an Access Control System?
An access control system is a security solution that restricts and monitors entry to buildings, rooms, or secure areas. Instead of traditional locks and keys, it uses electronic credentials such as proximity cards, PIN codes, fingerprints, or facial recognition to verify a person's identity before granting access.
Modern access control systems also log every entry and exit event, giving building managers a complete audit trail of who accessed which areas and when. This makes them essential for office buildings, data centers, factories, and any facility where security and accountability matter.
How Access Control Works
- A user presents their credential (card, fingerprint, face, or PIN) at a reader installed next to the door.
- The reader sends the credential data to a controller, which checks it against the authorized user database.
- If the credential is valid and the user has permission for that door at that time, the controller signals the electric lock to open.
- The door opens and the event is logged with timestamp, user identity, and door location.
- Managers can review access logs, add or remove users, and set schedules through management software.
ข้อดีหลัก
- Eliminate lost key problems — deactivate a card instantly if lost or stolen
- Complete audit trail of every entry and exit event
- Time-based access rules — restrict entry by schedule or shift
- Zone-based permissions — different access levels for different areas
- Integration with time attendance for automatic employee tracking
- Remote management — add users or unlock doors from any location
- Scalable from a single door to hundreds across multiple sites
- Reduced operational cost compared to rekeying traditional locks

How to Choose the Right Access Control System
- Assess how many doors and locations need to be controlled
- Decide between card-based, biometric, or hybrid credentials
- Consider whether contactless operation matters (post-COVID preference)
- Check user capacity requirements for your organization size
- Evaluate integration needs with attendance, CCTV, or visitor systems
- Determine if cloud management or on-premise server fits better
- Set a budget per door and factor in ongoing costs like cards
- Ask about warranty, maintenance, and local technical support
คำถามที่พบบ่อย
What is an access control system?
An access control system is a security system that controls who can enter or exit specific areas of a building using electronic credentials such as cards, fingerprints, face recognition, or PIN codes instead of traditional keys.
How much does an access control system cost?
Costs vary depending on the number of doors, credential type, and features. A basic single-door card access system starts from around 15,000-25,000 THB. Multi-door systems with biometrics and software typically range from 50,000-200,000 THB. Contact us for a customized quote.
Can access control integrate with time attendance?
Yes. Most modern access control systems can share data with time attendance software, so the same card or fingerprint used to open the door can also record clock-in and clock-out times automatically.
What happens if the power goes out?
Access control systems can be configured with backup batteries to maintain operation during power outages. Fail-safe locks will unlock during power loss for emergency exit, while fail-secure locks remain locked to maintain security.
Is face recognition better than fingerprint for door access?
Both have advantages. Face recognition is contactless and faster, making it more hygienic and convenient. Fingerprint readers are more affordable and work reliably in most environments. The best choice depends on your budget, hygiene requirements, and user preference.
