Online/Offline Working
Modes Switch
Automatic Online/Offline Working Modes Switch
Never lose control – CR20E intelligently monitors network connectivity and automatically switches between online/offline modes while keeping all data in sync.
- Host Mode: unlimited users and event logs for online management.
- Local Mode: user whitelist and local event logs for offline use.
- Auto Switch: online and offline modes switch automatically.
High-security encryption protection
The data interaction between the QR code access control hardware and software systems employs ciphertext methods, and utilizes encrypted HTTPS and MQTTS communication protocols to ensure data security. Additionally, it integrates multiple authentication methods such as signature verification and key verification, comprehensively enhancing the system’s security protection capabilities
Easy voice replacement
Voice output can be customized for project-specific access prompts.
