Hikvision DS-K2804 Four-Door Network Access Controller

The DS-K2804 is a four-door network access controller designed for businesses and facilities that need reliable, centrally managed access control across multiple entry points. It is well-suited for office buildings, warehouses, educational campuses and commercial properties where structured access management is a daily operational requirement.

Built on a 32-bit processor, the controller handles access events in real time without user-facing delays. Local storage supports up to 10,000 cards and 50,000 events, allowing the unit to operate independently when network connectivity is unavailable — an important consideration for environments where security continuity is non-negotiable.

TCP/IP communication with a self-adaptive network interface ensures straightforward integration into existing infrastructure. All data is transmitted with encryption. Wiegand W26/W34 interface compatibility means the DS-K2804 connects to most third-party card readers already in the field, reducing the cost and disruption of upgrades.

Real-world use cases include: access control for a four-zone office building; entry/exit management for a warehouse or production site; unified management alongside Hikvision IP cameras through iVMS-4200; replacing legacy access control hardware while retaining existing readers; local anti-passback enforcement at main entrances.

The controller is configured and managed via iVMS-4200, supporting user groups, access schedules, master card functions and remote door control. NTP time synchronization, a watchdog function and online firmware upgrades minimize on-site maintenance requirements.
