Secure expansive facilities with the Hikvision DS-K2704X Ultra Series Access Controller, Hikvision's top-tier solution for professional, large-scale access management. Natively controlling 4 doors with dedicated lock, exit button, door contact, alarm, and tamper interfaces, it scales to an impressive 128 doors by cascading up to 62 DS-K2M002X access modules via downstream RS-485 redundancy wiring—ensuring stability and fault tolerance in mission-critical setups like airports, subways, banks, large industrial sites, hospitals, universities, and corporate campuses.

Enterprise-level capacity includes 100,000 users, 200,000 cards, 10,000 fingerprints, and 600,000 event logs for handling high-traffic demands with fast processing. Advanced features deliver robust security: multi-factor authentication, anti-passback, multi-door interlocking, first person in rules, alarm linkage, tamper protection, and fire interface integration to comply with strict regulations.

Flexible reader support via onboard RS-485 (OSDP protocol) and Wiegand (via modules) accommodates biometric, card, PIN, QR code, or third-party devices. Gigabit Ethernet (10/100/1000 Mbps self-adaptive) with IPv4/IPv6 support provides reliable, high-speed connectivity. Configuration is straightforward via web browser—no dedicated software required—with seamless compatibility for Hik-Connect, HikCentral Professional, and integrated ecosystems.

Redundant RS-485 design maintains communication integrity over long distances or in challenging environments. Running on Linux with backup battery support, it ensures reliable operation from -10°C to 55°C. LED indicators for power, network, RS-485, and door status simplify monitoring and troubleshooting. Wall or DIN-rail mounting options make installation efficient. Future-proof your security infrastructure with this scalable, high-performance controller from Hikvision's premier Ultra Series.
