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

Model: DS-K3B801BX-L/MPg-Dp90 900mm Left

Who This Is For

Property managers specifying pedestrian access control for high-traffic lobbies, transport hubs, schools, or corporate office entries will find the Hikvision DS-K3B801BX-L/MPg-Dp90 built specifically for that brief. This is the left-lane pedestal in a swing barrier system, configured with a 900mm lane width to accommodate business-casual pedestrian flow including users with bags or light equipment. The integrated 2-way Mifare card reader handles bi-directional authentication without a separate reader housing, keeping the installation profile clean. The people-counting module adds live throughput data to your access control reporting - useful for occupancy compliance, shift management, and building analytics. With 24 pairs of infrared sensors, anti-tailgating logic, and a barrier that locks automatically against unauthorised force, this pedestal handles controlled entry and exit within a single lane unit. It is designed to pair with a matching right-lane pedestal and optional middle pedestal for wider or multi-lane deployments.

What This Barrier Actually Does

Who Buys This Model

• Corporate Facilities Managers: Specifying a staffed lobby entry where Mifare credentials are already issued company-wide and the 900mm lane width needs to accommodate employees carrying bags or laptops without causing bottlenecks.
• Transport Hub Integrators: Installing multi-lane pedestrian barriers at station concourses or transit interchanges where the 20-60 persons per minute throughput rating and adjustable barrier speed are required to match variable peak-hour passenger flow.
• School and University Security Teams: Controlling access to restricted campus zones where visitor card management (up to 3,000 visitor credentials stored onboard), people counting, and audible alarms for intrusion or reverse passing are all required from a single lane unit.
• Building Occupancy Compliance Officers: Using the Dp90 people-counting output to maintain real-time occupancy records for work health and safety compliance or fire safety capacity limits across multiple controlled entry points.

Honest Assessment

This pedestal is genuinely strong where lane throughput, credential storage depth, and built-in people counting matter simultaneously. The 24-pair IR curtain is a meaningful step above entry-level swing barriers that use fewer sensors, and the 120 Nm locking resistance gives the barrier real physical deterrence rather than just a light physical stop. Onboard storage of 60,000 cards and 180,000 records makes it practical for large organisations. The fire alarm auto-open and scheduled operating modes are features that matter to building compliance teams, not just security integrators.

Where it will not serve well: this is a single left-lane pedestal and requires a matched right-lane unit to form a complete lane - it cannot be installed as a standalone barrier. It is also not rated for outdoor use; installations exposed to weather or direct Australian sun will need an appropriate enclosure solution. For environments requiring facial recognition, QR code, or long-range RFID authentication, verify the specific reader module matches your credential type before ordering. The DS-K3B801BX-L/MPg-Dp90 is available through Security Australia.

Before You Buy

Quick Fit Check

• Good match if: You are specifying a Mifare credential-based access point in a high-traffic indoor environment - the 900mm lane width, 24-pair IR detection, and 60,000-card onboard storage are sized for corporate, education, or transit deployments at scale.
• Good match if: Your project requires integrated people counting at the barrier level without adding a separate overhead sensor - the Dp90 module delivers per-lane occupancy data directly to your access control reporting.
• You may need a different model if: Your entry point requires a narrower ADA-compliant lane, a wider accessible lane exceeding 1100mm, or outdoor weatherproof installation - a different barrier series or turnstile type within the Hikvision access control range would be more appropriate for those requirements.

Key Features & Technical Specifications

Real-World Scenarios

How It Compares

• Choose this if: You need bi-directional Mifare authentication, integrated people counting, and deep onboard credential storage (60,000 cards) in a single lane pedestal rated to handle 20-60 persons per minute.
• You may need a different model if: Your entry requires full-height physical security, outdoor installation, or a high-security anti-passback turnstile configuration - a flap barrier, full-height turnstile, or speed gate series from the Hikvision access control range would be more appropriate for those scenarios.
• Pairs well with: A compatible Hikvision access controller, Mifare card issuing hardware, and a matching right-lane pedestal of the same series to complete the lane installation.

Common Questions

1. Can this pedestal be installed as a standalone barrier without a matching right-lane unit?

   No. This is the left-lane pedestal only and requires a matching right-lane pedestal to form a functional lane. The swing barriers physically close across the lane opening between the two pedestals. A middle pedestal can be added if you need to create 2 lanes from a single installation run, but neither left nor right pedestal operates independently as a complete barrier.

2. Does the barrier open automatically during a fire or power failure?

   Yes, on both counts. When a fire alarm signal is received the barrier opens automatically to allow emergency evacuation. On power loss the default behaviour is free-passage mode - the barrier remains open. If the unit is fitted with an optional lithium battery backup, this fail-safe behaviour is maintained even during an extended outage, which is relevant for building compliance sign-off.

3. What does the Dp90 people-counting module actually record?

   The Dp90 module counts the number of people passing through the lane in each direction. This data is logged against the access control record, allowing facilities teams to extract occupancy figures per zone and per time period. It does not use overhead imaging - the count is derived from the barrier's sensor and authentication events, so it is tied directly to credentialled passage rather than free-flow foot traffic.

4. Will this barrier work if the network connection to the access controller goes down?

   Yes, within its onboard storage limits. The pedestal stores up to 60,000 enrolled cards and 3,000 visitor cards locally, so it continues to authenticate users and log records during a network outage. Up to 180,000 swipe records are retained onboard and can be synchronised once connectivity is restored. For sites with extended or frequent network interruptions, confirm that the expected card count stays within these local storage limits.

5. Does the anti-tailgating function work across multiple lanes, not just within a single lane?

   Yes. Anti-tailgating is supported for both single-lane operation and cross-controller configurations. This means the system can coordinate tailgating detection logic across multiple barrier pedestals connected to the same controller, reducing the risk of a person using a legitimate swipe at one lane to allow an unauthorised follower through an adjacent lane.

6. How much force can someone apply to push through the locked barrier?

   The barrier resists up to 120 Nm of applied force when locked. This is a confirmed mechanical specification - the barrier locks automatically without a valid authorisation signal and will not release under typical manual pressure. If the barrier detects that a person is caught between the panels, it will lock or stop movement to prevent injury. This is not a high-security physical barrier in the same category as a full-height turnstile, but it provides a meaningful deterrent for most commercial environments. The DS-K3B801BX-L/MPg-Dp90 is stocked by Security Australia for integration into larger access control projects.

7. Can the barrier speed be changed to handle different traffic densities?

   Yes. The barrier's opening and closing speed can be adjusted according to visitor flow. The rated throughput range is 20 to 60 persons per minute, and actual throughput will vary based on how quickly individuals present credentials and move through the lane. Speed adjustment is done through the controller configuration rather than a physical adjustment, and scheduled operation templates allow different speed profiles to be applied automatically at different times of day.

Cabling Considerations

• Power Cabling: This unit requires a dedicated 100-240 VAC mains circuit. It is not PoE-powered. A licensed electrician must install the mains connection to each pedestal in accordance with AS/NZS 3000 wiring rules.
• Network Connection: TCP/IP connection via Cat5e or Cat6 is required for controller communication, remote management, and record synchronisation. Run cable in conduit where it crosses floor areas or is exposed to foot traffic near the barrier base.
• RS-485 / RS-232: RS-485 and RS-232 interfaces are available for connection to third-party access controllers or integration with building management systems. Use shielded cable for RS-485 runs longer than 10m to reduce interference in electrically noisy environments.
• I/O Interface: Dry contact I/O terminals are available for fire alarm integration and external alarm outputs. Confirm the fire alarm panel output voltage and contact type against the barrier's I/O input specifications before wiring.
• Cable Entry: Plan cable entry points during the concrete or floor preparation stage. The pedestals are floor-mounted and cable routing inside the stainless steel housing is limited - confirm the cable entry position with the installation drawings before laying conduit.
