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

Model: DS-K3B801BX-R/MPg-Dp90

Who This Is For

When controlled pedestrian throughput and verifiable people counting are the priority, the Hikvision DS-K3B801BX-R/MPg-Dp90 is built for that brief. This is the right-lane pedestal in a swing barrier configuration, set at a 900mm lane width and fitted with a 2-way Mifare card reader and integrated people counting. It suits corporate building lobbies, university campuses, government facilities, transport hubs, and any high-traffic entry point where access needs to be credentialed, counted, and logged. Facilities managers and access control installers specifying a lane that handles 20 to 60 persons per minute will find the adjustable barrier speed, anti-tailgating logic, and TCP/IP network integration directly useful. This unit is the right-lane pedestal only - a matching left-lane pedestal and, for wider or multi-lane installations, a middle pedestal are ordered separately to complete the lane configuration.

What This Product Actually Does

Who Buys This Model

• Corporate Building Managers: Specifying a credentialed entry lane for a lobby with Mifare-based staff access cards already in use across the broader access control system.
• University and Campus Facilities Teams: Managing high-volume pedestrian flow at building entries where people counting data is needed for occupancy reporting and the 20-60 persons per minute throughput matches peak class-change traffic.
• Government and Secure Facility Installers: Installing at entry points requiring bi-directional access logging, anti-tailgating enforcement, and 180,000-record local storage for audit trail compliance.
• Transport Hub Operators: Deploying the barrier at station concourses or terminal entries where durable AISI304 stainless steel construction, adjustable lane width, and a rated MCBF of over 3,000,000 cycles justify the investment.
• Access Control Integrators: Completing a multi-lane configuration with TCP/IP, RS-485, and I/O interfaces that connect to existing access control platforms and building management systems.

Honest Assessment

The DS-K3B801BX-R/MPg-Dp90 handles high-throughput credentialed pedestrian access well. The 24-pair IR sensor array provides thorough lane coverage, the 2-way Mifare reader removes the need for separate exit readers, and the integrated people counting adds genuine occupancy management value without extra hardware. The 120 Nm force resistance and AISI304 stainless steel construction hold up in demanding environments. Card storage for up to 60,000 credentials plus 3,000 visitor cards suits large organisations, and 180,000 stored records support audit requirements. This unit is the right-lane pedestal only and must be paired with a matching left-lane pedestal to form a functional lane - single-pedestal operation is not supported. It is also a fixed-credential barrier; if the installation requires facial recognition, QR code, or multi-modal biometric authentication at the same lane, a different variant in the DS-K3B801 series would be more appropriate. Available through Security Australia.

Before You Buy

Quick Fit Check

• Good match if: Your site already uses Mifare cards for access control and you need a bi-directional credentialed lane with people counting at 900mm width - this pedestal pairs directly with that existing card infrastructure without requiring a reader upgrade.
• Good match if: The installation is a high-traffic lobby or campus entry where anti-tailgating enforcement is a stated requirement - the 24-pair IR sensor array and cross-controller anti-tailgating logic address that directly.
• You may need a different model if: The entry point requires facial recognition, QR code scanning, or biometric verification at the barrier - a different variant in the DS-K3B801 series with the appropriate reader module would be more suitable for multi-modal authentication.

Real-World Scenarios

How It Compares

• Choose this if: Your site uses Mifare credentials, needs bi-directional access logging, people counting, and anti-tailgating enforcement in a single-lane barrier rated for over 3,000,000 operational cycles.
• You may need a different model if: The entry point requires facial recognition, QR code verification, or biometric authentication - a different variant in the DS-K3B801 series with the matching reader module is the appropriate choice for those credential types.
• Pairs well with: A matching left-lane DS-K3B801 pedestal to complete the lane, a middle pedestal for wider accessibility configurations, and a compatible Hikvision access control server or third-party access management platform connected via TCP/IP or RS-485.

Common Questions

1. Does this pedestal work as a standalone barrier on its own?

   No. This is the right-lane pedestal only and requires a matching left-lane pedestal to form a functional lane. A swing barrier lane consists of at minimum 2 pedestals - one left, one right - facing each other across the lane opening. A middle pedestal can be added to create wider or multi-lane configurations, but it cannot be added without the left and right pair already in place.

2. Will this barrier work with our existing Mifare access cards?

   Yes, provided your cards comply with standard Mifare specifications. The integrated 2-way Mifare reader supports credential verification in both entry and exit directions. If your site uses a mix of card types or requires QR code, PIN, or biometric authentication alongside Mifare, confirm the specific reader variant is supported before ordering - this unit is the Mifare (MPg) configuration.

3. How does the people counting function work and what data does it provide?

   The people counting is integrated directly into the barrier. Each person passing through the lane in either direction is counted via the 24-pair IR sensor array. The count data is accessible via the system's access control management software over TCP/IP. It is a lane-level count tied to the credentialed passage event - it is not a separate overhead camera-based counting system. This suits occupancy monitoring and compliance reporting for facilities with defined capacity limits.

4. What happens to the barrier if the power fails or the network goes down?

   On power loss, the barrier defaults to a free-pass (open) status, which ensures the lane does not become a life-safety obstruction during an outage. If the unit is fitted with an optional lithium battery backup, the barrier remains in the open position while battery power lasts. If the network connection drops, the barrier continues to operate using locally stored credentials - up to 60,000 cards are held onboard, so a server outage does not lock out all users.

5. What does the anti-tailgating feature actually detect?

   The 24-pair infrared sensor array monitors the full length of the lane and detects multiple presence signatures within a single credential cycle. If a second person attempts to follow an authorised user through before the barrier closes, an audible and visual alarm triggers. Anti-tailgating operates in single-lane mode and also in cross-controller configurations where multiple lanes share detection logic. The system also alarms on reverse passing, climbing over the barrier, and overstaying within the lane beyond the valid passing duration.

6. Can the barrier speed and open/close timing be adjusted after installation?

   Yes. Barrier opening and closing speed can be configured via the management software to match the pedestrian flow at the site. The valid passing duration - the window in which a person must pass through after a credential is accepted - is also configurable. Scheduled operation is supported, allowing the barrier to automatically open or close at set times, for example remaining open during a defined low-risk period and returning to credentialed access outside those hours. Security Australia stocks this model as part of the broader Hikvision access control range.

7. What are the interface options for connecting this barrier to an existing access control system?

   The pedestal supports TCP/IP, RS-485, RS-232, and I/O interfaces. TCP/IP is the primary integration path for network-connected access control platforms. RS-485 supports connection to third-party controllers. The I/O terminals provide dry contact inputs for fire alarm integration and outputs for alarm signalling. Communication over TCP/IP is encrypted within the Hikvision protocol. Confirm RS-485 and I/O wiring requirements with the access control platform vendor before rough-in.

Cabling Considerations

• Power Cable: This unit runs on 100-240 VAC mains power. Each pedestal requires a dedicated mains feed - this is not a PoE or low-voltage device. Run a suitable-rated power cable to each pedestal position during rough-in and terminate in a weatherproof or concealed junction as appropriate for the installation environment.
• Network Cable: Cat5e or Cat6 cable to each pedestal for TCP/IP connectivity. Maximum standard Ethernet run of 100m applies. For longer runs, use a managed switch at an intermediate point.
• RS-485 Wiring: Shielded twisted pair cable recommended for RS-485 runs to third-party controllers. Keep RS-485 runs under 1200m and terminate the bus correctly at both ends to prevent signal reflection on longer installations.
• Fire Alarm Input: A dry contact cable run from the building's fire detection panel to the barrier I/O input is required for automatic evacuation behaviour. Coordinate with the fire contractor during rough-in - this cable run is easiest to install before the pedestal base is fixed to the floor.
• Floor Penetrations: Plan conduit penetrations at the pedestal base positions before pouring or finishing the floor surface. Each pedestal base is 160mm wide - conduit entry positions need to align with the internal cable routing points inside the pedestal housing.
