Hikvision DS-K3B801BX-M/MPg-Dp90 Swing Barrier MIDDLE Lane 900mm, 2 Way Mifare, People Count

Model: DS-K3B801BX-M/MPg-Dp90

Who This Is For

When managing a multi-lane pedestrian access point in a high-traffic environment is the priority, the DS-K3B801BX-M/MPg-Dp90 is the middle lane pedestal that connects two outer units to form a complete swing barrier system. Designed for subways, corporate lobbies, universities, and government buildings, this unit handles 2-way Mifare card authentication and includes built-in people counting - making it suited to sites that need both access control and occupancy data in a single lane. The 900mm lane width accommodates accessibility requirements without the full complexity of a wide-lane configuration. With acrylic swing barriers, 24 pairs of IR sensors, and a pedestal built from AISI304 stainless steel, this is a commercial-grade component for integrators and facilities teams specifying entrance control that needs to perform reliably under continuous daily use.

What This Barrier Actually Does

Who Buys This Model

• Commercial Integrators: Building multi-lane swing barrier systems for corporate lobbies or government facilities, specifying the middle pedestal to complete a 3-pedestal, 2-lane installation.
• University and Campus Facilities Teams: Managing controlled pedestrian access at building entrances where Mifare card credentials are already issued to staff and students, and bi-directional flow needs to be tracked.
• Transit and Transport Operators: Deploying barriers at station gates or transit hubs where throughput rates of 20 to 60 persons per minute are required and people counting data feeds into operational reporting.
• Occupancy Compliance Managers: Sites subject to building occupancy limits or WHS reporting obligations that need per-lane people count data as part of their access control record-keeping.
• Security Consultants on Upgrade Projects: Replacing older turnstile infrastructure with a wider, more accessible 900mm lane that meets modern accessibility standards without sacrificing anti-tailgating capability.

Honest Assessment

The DS-K3B801BX-M/MPg-Dp90 handles sustained, high-throughput pedestrian access well. The 24-pair IR sensor array gives meaningful detection depth for anti-tailgating, the 120 Nm locking resistance is a genuine physical deterrent, and the built-in people counting removes the need for a secondary counting solution. Card storage for up to 60,000 credentials and 180,000 swipe records means it scales to large organisations without constant purging. The 900mm lane also addresses accessibility without requiring a separate dedicated lane in most installations. Where this unit will not serve: it is a middle pedestal only and cannot function as a standalone lane - left and right outer pedestals are required to complete any lane configuration. It also does not support facial recognition or QR code authentication natively in this variant, so sites requiring those credential types will need to assess compatibility with an external reader. Installations requiring wider barrier panels or full-height barriers should review other product types. Available through Security Australia, this unit suits integrators who are specifying a complete multi-lane system from a single supplier.

Before You Buy

Quick Fit Check

• Good match if: You are building a 2-lane swing barrier installation using DS-K3B801 series outer pedestals and need a 900mm wide middle lane with integrated 2-way Mifare authentication and people counting in a single unit.
• Good match if: Your site has an existing Mifare card credential system and requires bi-directional access logging with 180,000-record on-board storage and anti-tailgating enforcement across multiple lanes.
• You may need a different model if: Your entry point requires a single self-contained lane with no middle pedestal, or you need facial recognition or QR code authentication built into the barrier - a different barrier variant or a full-height turnstile system may be more appropriate for those configurations.

Real-World Scenarios

How It Compares

• Choose this if: You are specifying a multi-lane swing barrier installation using DS-K3B801 series components and need the middle pedestal to include 2-way Mifare authentication and people counting at a 900mm lane width.
• You may need a different model if: Your site requires a standalone single-lane barrier without a middle pedestal, needs full-height barrier panels for higher security zones, or requires facial recognition as the primary credential type - a different barrier series or access terminal combination would be more appropriate.
• Pairs well with: DS-K3B801 series left and right outer pedestals (required to complete any lane), a compatible access control server or VMS for centralised card management, and an uninterruptible power supply to maintain barrier operation during short power interruptions.

Common Questions

1. Can this unit work as a standalone single-lane barrier on its own?

   No. The DS-K3B801BX-M/MPg-Dp90 is a middle lane pedestal only and requires a compatible left pedestal and right pedestal from the DS-K3B801 series to form a complete lane. It cannot operate independently. When specifying this unit, confirm that the outer pedestal models are included in your order before installation.

2. What does the people counting feature actually record?

   The Dp90 variant logs individual passage events per lane direction. This provides per-lane entry and exit counts that can be used for occupancy reporting, peak-traffic analysis, and compliance documentation. The people count data is stored alongside the standard 180,000 card swipe records and is accessible via the TCP/IP management interface.

3. Will this barrier work with our existing Mifare card system?

   Yes, provided your existing cards use the Mifare standard. The built-in reader in this variant supports Mifare authentication bi-directionally. If your site uses a different credential technology such as HID Prox, DESFire, or facial recognition, this variant is not the right fit and a different reader configuration should be specified.

4. How does the barrier behave during a power failure?

   Without a lithium battery backup, the barrier defaults to a free-pass (open) status during a power failure. If a lithium battery is installed, the barrier remains open when powered down. This fail-safe behaviour is standard practice for life-safety compliance and means the lane will not trap occupants during an outage. Confirm your site's power-down policy when configuring the unit during commissioning.

5. Does the barrier automatically open during a fire alarm?

   Yes. When the barrier receives a fire alarm signal via its I/O interface, all lanes open automatically to allow emergency evacuation. This behaviour is built into the firmware and requires no additional configuration beyond connecting the fire alarm output to the barrier's I/O terminals during installation.

6. How many cards and records can this barrier store on-board?

   The system stores up to 3,000 visitor cards and up to 60,000 standard cards, plus up to 180,000 swipe records. For most mid-to-large commercial sites, this on-board capacity is sufficient for day-to-day operations, with records exported to a central management system periodically. Sites with very high card volumes or extended audit retention requirements should confirm their record export schedule with their integrator. The DS-K3B801BX-M/MPg-Dp90 is part of the Security Australia range and suits integrators who need confirmed card and record capacity figures before specifying a system.

7. What happens if someone is caught between the barrier panels?

   The barrier stops immediately if it detects that a person is caught in the lane. The system will not continue to apply closing force in that situation. Additionally, the barrier locks to prevent further movement and triggers an alarm. The 120 Nm anti-tampering rating applies to unauthorised forced entry, not to a person caught mid-passage - in that case, the safety stop takes priority.

8. What communication interfaces does this barrier support for integration with an access control platform?

   The barrier supports TCP/IP, RS-485, RS-232, and I/O interfaces. TCP/IP is the standard connection method for integration with modern access control management software. RS-485 is available for legacy platform integration. Before deploying, confirm your access control platform's supported Hikvision barrier protocol, as communication data is encrypted and the integration may require specific SDK or driver configuration from your software vendor.

Cabling Considerations

• Network Cabling: Cat5e or Cat6 for TCP/IP connection to the access control management system. Run a dedicated cable to each pedestal - avoid sharing network runs with other high-traffic devices on the same switch port.
• Power Cabling: 100-240 VAC mains power required per pedestal. A dedicated circuit per lane (2 outer pedestals + 1 middle pedestal) is standard practice. Confirm circuit load calculations with a licensed electrician before installation.
• RS-485 Wiring: If integrating with a legacy access control platform via RS-485, use a shielded twisted pair cable. Keep RS-485 runs under 1200m and use proper termination resistors at each end of the bus to avoid signal degradation.
• I/O Connections: The fire alarm input and auxiliary alarm outputs connect via the I/O terminals. Use screened cable for I/O runs to minimise interference, and confirm terminal pinout with the installation manual before wiring. Fire alarm integration must be tested and verified by the commissioning technician before handover.
