Hikvision DS-K2704X(P) Enterprise Access Controller with Backup Battery Support
The Hikvision DS-K2704X(P) is an enterprise-grade 4-door access controller designed for large commercial access control projects requiring centralised management, high reliability and backup power capability. It controls 4 doors natively and can expand to 128 doors through compatible DS-K2M002X access modules.
Unlike standard controller deployments, the DS-K2704X(P) supports backup battery charging and discharging, helping maintain access control operation during power interruptions. Combined with anti-passback, multi-door interlocking, RS-485 redundancy and web-based management, it provides a scalable access control platform for schools, hospitals, strata buildings, warehouses, airports, commercial facilities and critical infrastructure projects.

Why Choose the Hikvision DS-K2704X(P)?
Built for Multi-Door Projects
The DS-K2704X controls 4 doors directly and can scale up to 128 doors with DS-K2M002X modules. That makes it ideal for staged projects where the access control system needs to grow over time.
Enterprise Access Control Backbone
Instead of relying on standalone readers at every door, the DS-K2704X gives your site a centralised controller for door permissions, events, alarms and system management.
Web Browser Configuration
Configure the controller through a web browser without needing a separate software application for basic setup and management.
Large User & Event Capacity
Supports up to 100,000 users, 200,000 cards, 10,000 fingerprints and 600,000 events, making it suitable for large staff, tenant, contractor and visitor environments.
Professional Access Control Features
Supports anti-passback, multi-door interlocking, multi-factor authentication and first-person-in access control workflows for higher-security sites.
Reliable RS-485 Expansion
Five downstream RS-485 interfaces support access module expansion, redundancy and stable communication across larger deployments.
Designed for Backup Power Applications
Supports battery charging and discharging functionality, helping maintain access control operation during power interruptions when used with compatible backup batteries.

Installation Notes
Professional Installation Recommended
This is a commercial access control controller and should be installed by a qualified security technician or licensed professional where required.
Plan the Door Hardware First
Confirm every door’s lock type, exit method, door contact, fire trip requirement and power design before ordering.
Use the Right Reader Layout
Decide whether each door needs entry-only, entry/exit readers, QR terminals, card readers or intercom terminals.
Allow Room for Expansion
If the site may grow later, design RS-485 module locations, enclosure space and power capacity from the start.
