How the eSSL Door Access Control System Operates
- ❶ Users Enrolled: Admin registers credentials (cards, biometric data) into the Access Security System 3.5 software.
- ❷ Access Rules Set: Define who can enter which door, during what time zone, and with security constraints like anti-passback.
- ❸ Live Authentication: Reader sends card ID to C3-400 controller via Wiegand or RS-485 protocol at the door.
- ❹ The Decision: Controller instantly checks card against database and activates lock relay for seamless entry.
- ❺ Compliance & Audit: Every access attempt is logged in the 100,000-event buffer, complete with timestamps for safety audits.
Expandable & Network-Ready Architecture
The eSSL C3-400 is designed for scalable deployments across multiple doors. One controller can manage up to 4 doors and thousands of users. For more doors, multiple controllers can be installed on the same network and managed from the centralized software, keeping management simple as your organization expands.[reference:0]
Seamless Integration with HRMS & Payroll Systems
The eSSL C3-400 integrates effortlessly with ERP systems, third-party HRMS platforms like Spine, GreytHR, and HROne, CRM software like Zoho, and payroll software like Candle, Saral, and Oracle — creating a unified workforce and security ecosystem.
