What Is an Indoor Proximity Access Control Reader?
An indoor proximity access control reader is a keypad-based access terminal that lets users unlock a door with a proximity card, a PIN code, or a combination of both. It reads the card within seconds, verifies the credential, and triggers the relay to release the electric lock. Because it is compact and self-contained, it is an ideal choice for offices, apartments, hotels, server rooms, and small commercial buildings.
Card + PIN: Two-Factor Security for Entry Points
One of the most practical security upgrades is combining card and PIN credentials:
- Card only — fast entry for daily staff or residents.
- PIN only — flexible temporary access without issuing cards.
- Card + PIN — two-factor verification for higher-security areas.
With support for up to 1,000 cards and a 4-digit PIN, the system handles small to mid-sized access groups without extra hardware.
125KHz vs 13.56MHz: Choosing Your Card Technology
Modern proximity readers support different card frequencies, and choosing the right one depends on your existing credentials:
- 125KHz EM cards — the most widely used, low-cost proximity cards, perfect for standard access control.
- 13.56MHz smart cards — higher security, larger data capacity, and compatibility with more advanced systems.
This reader can be configured for either technology, so you can match the cards you already use.
Wiegand WG26 Output & Controller Compatibility
The Wiegand interface is the standard connection between readers and access controllers. With WG26 output, this keypad reader integrates with most third-party access control panels, making upgrades and replacements straightforward.
Relay Output & Electric Lock Integration
Built-in relay output directly controls electric locks, magnetic locks, and other door-locking devices:
- Relay output: 12VDC / 2A
- Electric lock output: up to 3A
- Short-circuit protection for reliable operation
This simplifies installation — no separate relay module is required for single-door applications.
Metal Keypad & Backlit Design
Built with a metal housing and backlit keys, the reader is both durable and user-friendly:
- Backlit keypad — clearly visible at night or in dim corridors.
- Metal construction — resists wear, tampering, and daily use.
- Compact size (130×58×24mm) — fits neatly beside doors and frames.
Where to Install
- Office building entrances
- Apartment and rental properties
- Hotel rooms and service areas
- Server rooms and equipment rooms
- Small shops and storage areas
