Who Is This For?
This system is ideal for:

- Independent warehouses or workshops
- Private facilities (gates, back entrances, storage rooms)
- Any scenario where you need simple access management without a centralized controller.
Key Features (Designed for Practical Use)
- User capacity: Supports up to 1000 users, plus 2 manager cards for easy permission control (add/delete users without professional tools).
- Compatibility: Works with external Wiegand 26-44 RFID readers or Touch Memory readers. Pairs seamlessly with all standard locks (electric strikes, magnetic locks) and exit buttons.
- Installation: No complex wiring required. We provide a step-by-step manual with clear diagrams—most users finish setup in 60 minutes or less.
- Durability: Operates in temperatures from -20℃ to 60℃, with IP54 dust and water resistance—suitable for both indoor and semi-outdoor use.
Compatibility Check
Before purchasing, confirm your existing hardware meets these requirements (no need to replace devices):
- Readers: Wiegand 26-44 protocol (RFID or Touch Memory)
- Locks: 12V DC electric strikes, magnetic locks, or other standard access control locks
- Power supply: 12-24V DC (compatible with most standard power adapters)
Frequently Asked Questions
Q: Can I manage users without a computer?
A: Yes—use the 2 included manager cards to add, delete, or modify user permissions directly on the device, no software needed.
Q: How long does the system last?
A: We test each unit for 3000+ consecutive uses. The average service life is 5+ years with normal use.
Q: Is it suitable for outdoor doors?
A: The main unit is IP54-rated (dust and splash-proof), so it works for semi-outdoor areas (e.g., covered lobbies). For fully exposed doors, pair it with an IP66 waterproof reader (available as an optional accessory).
