Introduction to the DS-K2604T and its key features
The DS-K2604T 4-Door Pro-Series Network Access Controller is a purpose-built access control unit aimed at medium-to-large enterprise installations. Offering support for up to four doors, multiple reader interfaces and generous on-board capacity, the DS-K2604T is designed to run as part of a managed security ecosystem or as a resilient offline controller with local storage and battery backup. Its combination of high card/event capacity, flexible reader protocol support (Wiegand and RS-485/OSDP), and enterprise features such as anti-passback, multi-card authentication and door interlock make it a strong choice for integrators and organisations seeking a reliable and scalable access control backbone.
- 4 doors supportedwith lock outputs and reader inputs for common multi-door deployments.
- Large capacity— up to 100,000 cards/users and up to 300,000 event records stored locally.
- Flexible reader support— Wiegand (W26/W34) and RS-485/OSDP for third-party readers and higher security transports.
- Enterprise controls— anti-passback, blacklist handling, multi-card/first-card modes, interlocking and alarm/event upload.
- Offline resilience— local storage plus standby battery support to maintain operation during network outages.
- Integration— compatible with iVMS-4200, iVMS-4200 AC and HikCentral for centralised management.
Detailed description of specifications and benefits
The DS-K2604T pairs practical hardware specifications with software-friendly integrations to serve contemporary access control requirements. Below are the key specification areas and the real-world benefits they deliver.
- Card/user capacity:Up to 100,000 — supports large employee populations, tenant lists or long-term credential inventories without frequent database pruning.
- Event capacity:Up to 300,000 records — keeps a comprehensive local event history for forensic review during network outages or before offload to a central server.
Benefit: High capacities reduce the need for frequent maintenance, simplify large deployments and make the controller suitable for campuses, corporate HQs and multi-tenant buildings.
- Reader interfaces:Up to 4 Wiegand readers (W26/W34) and support for RS-485/OSDP readers (up to 8 depending on setup).
- Inputs/outputs:4 exit buttons, 4 door contacts, 4 alarm inputs and 4 alarm outputs, plus tamper input.
Benefit: Multi-protocol reader support lets you mix legacy Wiegand readers and modern OSDP devices, offering an upgrade path to more secure, encrypted reader communications while retaining compatibility with existing hardware.
- Network:TCP/IP (Ethernet) with support for RS-485, eHome and ISAPI interfaces.
- Protocols:Wiegand and OSDP where supported; NTP/manual/auto time sync for accurate event timestamps.
- Platform integration:Works with iVMS-4200 / iVMS-4200 AC / HikCentral for unified monitoring, configuration and reporting.
Benefit: Standard network protocols and vendor integrations make centralised management, firmware upgrades and event correlation straightforward, improving operational efficiency for security teams.
- Power supply:12 V DC, 1 A with standby battery support for continued operation during outages.
- Power consumption:With load ≤ 100 W; without load ≤ 4 W.
- Operating environment:−20 °C to 65 °C, 10%–90% non-condensing humidity.
- Dimensions (boxed):373 × 345 × 98 mm; weight information is limited in available data.
Benefit: Support for backup battery and broad operating temperature/humidity ranges makes the DS-K2604T suitable for indoor installations that require consistent uptime and predictable power management.
- Anti-passback:Prevents credential sharing and enforces logical entry/exit sequences.
- Interlocking:Configurable multi-door interlock for secure vestibules or airlock entry points.
- Alarm/event handling:Local alarm inputs/outputs and blacklist management for prompt protection responses.
Benefit: These features support higher-security workflows and reduce the risk of unauthorised access or tailgating in sensitive areas.
Use cases and scenarios where the DS-K2604T excels
The DS-K2604T is particularly well suited to environments that need enterprise-grade capacity and resilience across multiple doors. Typical use cases include:
- Corporate headquarters and large office buildings:Centralised management of thousands of employees, contractors and visitors with long-term event retention and integration into security management systems.
- Educational campuses and multi-building facilities:Support for many users and mixed reader deployments across dorms, labs and administrative zones.
- Multi-tenant commercial buildings:Segmented access control per tenant combined with interlock and anti-passback policies to regulate shared common areas.
- Data centers and secure facilities:Multi-card/multi-factor modes, interlocking doors and robust event logging help meet compliance and audit requirements.
- Retail complexes and logistics hubs:High event logging capacity and alarm outputs facilitate fast incident response and audit trails.
The controller’s offline capability and battery backup make it valuable in locations where continuous network connectivity cannot be guaranteed, or where redundancy is required for business continuity.
Comparisons with similar products in the market
When evaluating the DS-K2604T against alternatives, consider three main axes: capacity, protocol support and integration ecosystem.
- Capacity:Many entry-level 4-door controllers limit users to a few thousand cards and a modest event buffer — the DS-K2604T’s 100k user and 300k event capacities place it firmly in the enterprise class and reduce system maintenance for larger sites.
- Reader protocols:Controllers that only support Wiegand lack OSDP’s encrypted communications. The DS-K2604T supports both Wiegand and RS-485/OSDP, enabling more secure reader deployments and smoother migration from legacy hardware.
- Integration and software:Controllers from established video and security vendors (including Hikvision) often plug into wider management suites (HikCentral, iVMS), which is a strong advantage if you plan a unified security platform. Some competitors offer similar features, but integration ease and vendor ecosystem can be decisive.
- Resilience features:Battery backup and significant local storage are not universal. For locations where uptime under network loss matters, DS-K2604T’s offline operation is an advantage.
Competitors to consider include enterprise-class controllers from other major security vendors. The right choice will depend on your existing ecosystem (camera and VMS vendor), desired reader protocol (OSDP vs Wiegand), and capacity needs.
Customer testimonials and installer feedback
Official public testimonials for this exact model may vary by vendor channel. Based on typical installer and integrator feedback for Pro-series Hikvision controllers, common positive points include:
- "Reliable event buffering during network outages — we could still audit entry events after reconnecting the controller."
- "Support for mixed readers made our migration project much simpler; we upgraded some doors to OSDP while keeping legacy readers elsewhere."
- "Integration with the corporate VMS simplified alarms and camera pop-up on access events."
Constructive feedback from projects tends to focus on following best practices for secure deployments (firmware management, network segmentation and using secure reader protocols where possible) and ensuring installers confirm CE/UKCA and local regulatory compliance as part of project acceptance testing.
Conclusion — why the DS-K2604T is a great choice
The DS-K2604T 4-Door Network Access Controller is a robust, enterprise-focused device that balances high capacity, flexible reader support and operational resilience. It is especially well suited to organisations that need to manage large user bases, retain extensive event logs locally and support a mix of legacy and modern access readers. Integration with Hikvision management platforms, offline battery-backed operation and advanced access controls such as anti-passback and interlocking make this controller a pragmatic choice for campus, corporate and secure-facility deployments.
Pricing note:Provided pricing data lists a cost price of 294.91 and a suggested price of 379.00 (currency not confirmed). Confirming the currency will allow for accurate MSRP tiers and conversions.
