DA1537
Product Number：DA1537The DA1537 Crystal Series Palm Vein Access Controller utilizes contactless palm vein recognition technology to provide secure and reliable identity authentication for high-security environments. It integrates event logging, time scheduling, group management, alarm I/O, and remote control functions to help improve access management efficiency. A built-in backup battery provides temporary power during outages to maintain system operation.
- High-Precision Biometric Authentication: Supports palm vein recognition with a scanning distance of 10–30 cm, providing secure and contactless verification.
- Large-Capacity Storage: Supports up to 4,000 credentials (including 2,000 palm vein templates) and stores up to 4,000 access event records.
- Multi-Level Alarm Protection: Built-in alarms for tamper detection, forced entry/exit, and door-open timeout, with relay linkage support to enhance security.
- Network & Power Outage Protection: Supports offline verification of valid cards and includes a built-in lithium battery to ensure the RTC IC operates normally for approximately 60 days during power outages.
- Flexible Time Schedule Management: Provides independent time zone settings for 7 days per week and up to 8 access periods per day, enabling fine-grained personnel access control.
