DA1538
Product Number：DA1538The DA1538 Crystal Series Face Recognition Access Controller utilizes contactless facial recognition technology to provide fast and reliable identity authentication. It is ideal for office buildings, factories, and other high-traffic environments. Supporting essential access control functions such as event logging, time scheduling, and remote control, it helps improve entrance management efficiency while meeting everyday operational needs.
- High-Performance Facial Recognition: Supports facial feature recognition with a detection range of 40–90 cm (optimal at 50 cm) and is suitable for user heights from 1.2 to 2.1 m, delivering fast and contactless access.
- Large-Capacity Data Storage: Stores up to 100 facial templates; supports up to 4,000 card records including access and control cards, with a built-in buffer for 4,000 access control event logs.
- Intelligent Security Mechanisms: Equipped with multiple alarms including tamper detection, forced entry/exit, and door-open timeout; supports patrol card mode (record only, no door unlock) to ensure inspection activities do not compromise security.
- Stable and Reliable Operation: Built-in lithium battery maintains normal clock operation for approximately 60 days, and offline verification ensures valid access decisions even during network interruptions.
- Flexible Access Control Management: Supports independent time zone settings for 7 days per week and up to 8 access periods per day, with flexible holiday schedules and access rules configurable for different user roles.
