Access Control

Building a secure access control system requires reliable identification hardware and fail-safe locking mechanisms. Whether you need 13.56MHz RFID readers for office entry, NTAG215 NFC tags for smart automation, or heavy-duty electric bolt locks for commercial doors, we have the exact components. Backed by 20 years of engineering experience in Sham Shui Po, our technical team provides on-site hardware matching and system design advice to ensure your security infrastructure operates flawlessly.

Access Control Hardware & Specifications Guide

Selecting the correct access control components dictates the security level and fire safety compliance of your premises. Here is a technical breakdown of our core security inventory:

Component Category Key Technical Specifications Best Use Case
RFID & NFC Identification 13.56MHz IC / 125KHz ID Readers, NTAG213/215 Tags Employee badge scanning, smart home automation, and secure entry keypads.
Electric Locks Magnetic Locks (Maglocks), Electric Drop Bolts, Fail-Safe Securing glass, wooden, and metal doors in commercial buildings.
Exit Buttons & Emergency No-Touch IR Sensors, Break-Glass Emergency Releases Hygienic clinic exits and fire safety compliant emergency escape routes.
Access Control Power Supplies 12V/15V Output, Built-in Relay Delay, Battery Backup Support Providing stable, high-surge current to electric locks and keypads.

Important Note (Security Vulnerabilities & Fail-Safe Hazards): Most magnetic locks and electric drop bolts operate on a "Fail-Safe" mechanism, meaning they require continuous power to stay locked. In the event of a power outage, the door will automatically unlock to comply with fire safety regulations. You must pair fail-safe locks with a dedicated Access Control Power Supply equipped with a backup battery (UPS) to prevent your building from being left unsecured during blackouts. Furthermore, older 125KHz ID cards transmit unencrypted serial numbers and can be cloned in seconds. For high-security areas, always upgrade to encrypted 13.56MHz IC systems.

Frequently Asked Questions (FAQ)

Q: What is the difference between IC (13.56MHz) and ID (125KHz) access control systems?
A: IC cards operate at a higher frequency (13.56MHz) and support two-way read/write encryption, making them highly secure and suitable for payment or strict access control. ID cards (125KHz) are read-only and broadcast a static, unencrypted number that is easily duplicated by cheap cloning devices. We strongly recommend IC systems for all new commercial installations.

Q: Can I use a standard 12V CCTV power adapter for my electric bolt lock?
A: No. Electric locks draw a massive surge of "inrush current" when actuating. A standard CCTV adapter cannot handle this sudden spike, which will cause a severe voltage drop. This often results in the lock failing to engage or the access control keypad continuously rebooting. You must use a dedicated Access Control Power Supply with built-in capacitors and relay delay circuits.
