Description
The Hikvision DS-K2702WX-E1 network access controller manages two doors in the base configuration and serves as the core of a scalable access control system: with DS-K2M002X expansion modules the system grows to 126 doors without replacing the central unit. The controller ships in a metal cabinet with a lock — the electronics are protected from tampering and installation is simplified. The solution suits offices, industrial facilities and educational institutions where the access system grows together with the site.
Communication with the modules runs over a redundant RS-485 bus: if one line is damaged, data exchange continues over the second one and the doors are never left uncontrolled. The controller supports flexible passage scenarios and schedules, while integration with Hikvision video surveillance links access events to cameras and the video archive. Readers connect via RS-485 (OSDP) or Wiegand — cards, PIN codes and Hikvision QR readers work in a single system.

Installation and setup
The controller cabinet is placed in a server room or a protected technical room, close to the power supply and the door wiring. The RS-485 bus to the expansion modules is laid along two independent routes — only then does the redundancy truly work. Locks, exit buttons and door position sensors connect to the door modules, while the system is configured over the network from Hikvision software. The design should include headroom in the door count: adding a module to an existing bus is easier than rebuilding the system. The controller is in stock at our Tashkent warehouse; we design and install turnkey access control systems.
