ENTRYPASS EP.HIO.PSU Hybrid I/O Control Panel Singapore | 8 Inputs 8 Outputs | RS485 TCP/IP Modbus | Alarm Elevator Control Repair Replace

The ENTRYPASS EP.HIO.PSU Hybrid Input / Output Control Panel is a flexible security-system controller designed for alarm monitoring, elevator access control and I/O integration. It combines digital inputs and relay/output control with both serial and Ethernet communications, making it suitable for existing ENTRYPASS systems that require interaction with alarms, floor controls, sensors and other security devices.

The standard EP.HIO.PSU provides 8 digital inputs and 8 digital outputs, with expansion to 16 inputs and 16 outputs using the EP.HIO.EXP expansion board. It supports RS232/RS485, 10/100 Mbps Ethernet, Modbus Serial and Modbus TCP/IP, allowing it to serve both legacy serial installations and network-connected systems.

SGCCTV – Choicecycle CCTV provides ENTRYPASS EP.HIO.PSU troubleshooting, repair, replacement, expansion and access-control upgrading in Singapore, including alarm and elevator-control applications.

ENTRYPASS EP.HIO.PSU Full Specifications

8 Inputs + 8 Outputs

The standard EP.HIO provides:

8 DIGITAL INPUTS

and:

8 DIGITAL OUTPUTS

This allows the controller to receive status information from external equipment and provide controlled outputs to other systems.

With the EP.HIO.EXP, capacity can be expanded to:

16 INPUTS + 16 OUTPUTS

per expanded HIO configuration.

This flexibility makes HIO useful for both alarm-monitoring and elevator-control applications.

What Is Hybrid I/O?

I/O means:

INPUT / OUTPUT

An input receives information from another device.

Examples can include:

Alarm Contact

Door Contact

Emergency Push Button

Sensor

Equipment Fault Contact

Lift Status Contact

Fire Alarm Interface Contact

An output allows the controller to activate or signal another device or interface.

Examples can include:

Relay Activation

Buzzer

Strobe

Floor Control

Alarm Indication

External Equipment Interface

This is why the EP.HIO can be used for considerably more than a conventional card-access door.

Alarm Monitoring Application

The EP.HIO can be used to receive alarm or equipment status through its digital inputs.

A basic architecture can be:

SENSOR / ALARM CONTACT

↓

EP.HIO INPUT

↓

EVENT PROCESSING

↓

ENTRYPASS SYSTEM

↓

ALARM / ACTION / OUTPUT

Depending on the programmed system, an input event can be monitored and associated with a corresponding action.

Applications can include:

Emergency Push Buttons

Equipment Alarms

Door Status

Security Sensors

Building Alarm Contacts

Fault Monitoring

Alarm Annunciation

The exact implementation depends on the project design.

Elevator Access Control Application

The HIO is also designed for elevator access-control applications.

In an elevator system, outputs can be used as part of the interface that enables authorised floor selections.

A simplified architecture can be:

CARD / CREDENTIAL

↓

ENTRYPASS ACCESS CONTROL

↓

EP.HIO

↓

FLOOR OUTPUT

↓

LIFT INTERFACE

↓

AUTHORISED FLOOR ENABLED

The ENTRYPASS architecture supports elevator access configurations where individual cardholders can be assigned different floor-access permissions.

Elevator Control from 8 to 136 Floors

Within supported ENTRYPASS elevator architectures, the HIO can form part of installations scaling from 8-floor control up to 136 floors, depending on the master controller, HIO expansion arrangement and overall system design.

For example:

Employee A → Floors 2–5

Employee B → Floor 8

Management → Floors 2–20

Contractor → Designated Floor Only

Visitor → Temporary Authorised Floor

The actual permissions are determined by the access-control configuration and lift integration.

RS485 Communication

The EP.HIO supports a user-configurable:

RS232 / RS485 SERIAL PORT

RS485 is widely used in access-control and building-security installations because it can connect distributed equipment over longer cable distances than typical short-range serial interfaces.

However, RS485 communication depends on correct:

A/B Polarity

Cable Condition

Device Address

Termination

Topology

Communication Settings

Electrical Environment

When an HIO becomes intermittently offline, the controller itself may not necessarily be defective.

TCP/IP Ethernet Network

The EP.HIO also provides:

RJ45 10/100 Mbps Ethernet

This allows the HIO to communicate across a compatible IP network rather than depending entirely on serial communication.

A networked architecture can be:

EP.HIO → RJ45 → NETWORK SWITCH → LAN → SERVER

This is particularly useful where security equipment is distributed throughout a building.

Modbus Serial

The EP.HIO supports:

MODBUS SERIAL

This allows compatible serial communications for integration applications.

The exact Modbus architecture, register mapping and third-party interface requirements should be confirmed during system design rather than assuming every Modbus device can be connected without configuration.

Modbus TCP/IP

The HIO also supports:

MODBUS TCP/IP

This provides Modbus communications over the Ethernet network.

Therefore, the EP.HIO supports dual communication modes:

MODBUS SERIAL + MODBUS TCP/IP

This is particularly useful when maintaining an older security installation while progressively moving toward network-based infrastructure.

Built-In Web Server

An important EP.HIO feature is its built-in web server.

Network parameters can be configured through the controller’s web interface, including items such as:

IP Address

Subnet Mask

Server IP

and related network parameters.

The onboard web architecture also supports firmware management for the HIO platform.

This can simplify configuration compared with older equipment requiring factory-level programming for network changes.

Active Event Transmission

The HIO architecture is designed to actively transmit current event information to the host server when operating through the supported network architecture.

Instead of relying solely on a host computer repeatedly polling stored events, this design can allow events to be delivered more quickly for processing.

This is particularly useful for:

Alarm Monitoring

Security Events

Emergency Inputs

Elevator Control

Building I/O Monitoring

where timely event reporting matters.

Open Trigger & Close Trigger

The EP.HIO supports:

OPEN TRIGGER

and:

CLOSE TRIGGER

This allows different types of dry-contact or compatible input arrangements to be accommodated.

When replacing an existing HIO, the existing input logic must be recorded carefully.

A technician should not assume every connected device uses the same trigger state.

Toggle Mode & Duration Mode

Current HIO specifications include:

TOGGLE MODE

and:

DURATION MODE

These modes provide flexibility in how outputs behave after an event.

Depending on system programming, an output may need to change state or operate for a defined duration.

This can be useful for:

Alarm Outputs

Elevator Floor Control

External Relays

Security Indicators

Building Equipment Interfaces

One-to-Many / Many-to-One / Many-to-Many

The HIO architecture supports flexible relationships between inputs and outputs.

Depending on configuration, applications can be designed around:

ONE-TO-MANY

One event controls multiple actions.

MANY-TO-ONE

Several events can trigger a common output.

MANY-TO-MANY

Multiple inputs interact with multiple outputs according to programmed logic.

This flexibility makes the HIO useful for customised security and building-control applications.

EP.HIO.PSU vs EP.HIO.PCB vs EP.HIO.EXP

There are three important model references to distinguish:

Therefore, customers should not confuse an HIO expansion board with a complete HIO controller.

The exact existing equipment should be checked before ordering replacement parts.

EP.HIO.EXP Expansion Board

If more I/O points are required, the EP.HIO.EXP provides an additional:

8 INPUTS + 8 OUTPUTS

When combined with the HIO controller, this expands the system to:

16 INPUTS + 16 OUTPUTS

This can be useful for larger alarm-monitoring or elevator-control applications.

EP.HIO.PSU Repair Singapore

An HIO installation can develop several different types of faults:

Controller Completely Dead

No LAN Connection

Cannot Ping Controller

RS485 Offline

Modbus Communication Failure

Input Not Detecting

Output Relay Not Operating

Alarm Event Missing

Elevator Floor Not Enabled

Intermittent Communication

Controller Rebooting

Power Supply Failure

Expansion Board Offline

Server Cannot Receive Events

Network Configuration Lost

Correct diagnosis should identify which section of the system is actually responsible.

Input Not Working

If one HIO input does not detect an alarm or sensor, troubleshoot:

FIELD DEVICE → CONTACT → CABLE → TERMINAL → HIO INPUT → CONFIGURATION

Possible causes include:

Faulty Sensor

Incorrect Open/Close Trigger Setting

Broken Cable

Loose Terminal

Wrong Input Mapping

Failed Input Circuit

Configuration Error

If seven inputs operate correctly and only one does not, replacing the entire controller may be unnecessary.

Output Not Working

If an HIO output fails to activate:

SOFTWARE / EVENT → HIO → OUTPUT → RELAY / INTERFACE → FIELD EQUIPMENT

Check:

Output Programming

Time Zone

Event Logic

Terminal Connection

Relay / Output Condition

Connected Load / Interface

Power Supply

Expansion Board

For elevator applications, the lift-side interface should also be checked by the appropriate responsible party.

RS485 Offline Troubleshooting

If serial communications fail, check:

RS485 A/B Wiring

Cable Continuity

Terminal Tightness

Device Address

Communication Settings

Termination

Electrical Interference

Controller Power

HIO Electronics

A reversed RS485 pair or damaged communication cable can create a fault that appears to be a failed controller.

TCP/IP Offline Troubleshooting

If the HIO cannot communicate over Ethernet, troubleshoot:

HIO → RJ45 → PATCH CABLE → NETWORK SWITCH → LAN → SERVER

Check:

Power LED

LAN LED

Ethernet Cable

Switch Port

IP Address

Subnet Mask

Server Address

IP Conflict

Network Routing

Firewall / Network Policy

HIO Network Interface

Replacing the controller before checking the network can result in unnecessary cost.

HIO Power Supply Failure

The PSU should also be checked when the controller behaves unpredictably.

Power problems may cause:

Random Reboot

Communication Drop

Output Instability

Input Errors

Controller Offline

LAN Disconnect

Complete System Failure

The EP.HIO specification includes a 2.5A resettable fuse, but the complete PSU and electrical supply should still be inspected when troubleshooting.

Repair or Replace EP.HIO.PSU?

The objective should be to replace the defective component rather than automatically replacing the entire security system.

Replacing an Existing EP.HIO.PSU

Before removing an old HIO, record the existing configuration carefully.

Important information includes:

IP Address

Subnet Mask

Server IP

RS485 Wiring

Device Address

Input Mapping

Output Mapping

Open / Close Trigger Settings

Toggle / Duration Settings

Modbus Configuration

Connected HIO Expansion

Elevator Floor Mapping

Alarm Logic

Time Zones

Field Wiring

This is especially important in live commercial buildings where a single HIO may control many security functions.

Elevator Control Safety

The HIO can provide access-control outputs for elevator applications, but it should not be treated as the elevator’s primary safety controller.

Access-control technicians should work only on the approved security interface and coordinate lift-side work with the appropriate elevator contractor or responsible party.

The lift’s proprietary safety circuits should not be altered as part of an ordinary access-control replacement.

Alarm Integration

The EP.HIO can also provide a useful bridge between physical security events and central monitoring.

For example:

EMERGENCY BUTTON

↓

HIO INPUT

↓

ENTRYPASS EVENT

↓

HIO OUTPUT / SECURITY RESPONSE

A properly designed system may also combine compatible:

ACCESS CONTROL + ALARM + CCTV

so that security personnel can use both alarm information and video evidence during incident investigation.

Preventive Maintenance

Periodic maintenance for an EP.HIO installation should include:

PSU Voltage

Controller Status

LAN Communication

RS485 Communication

Input Testing

Output Testing

Expansion Board

Terminal Tightness

Network Settings

Event Reporting

Alarm Operation

Elevator Floor Control

Server Communication

For critical applications, actual input/output operation should be tested rather than relying only on LED status.

ENTRYPASS EP.HIO.PSU HYBRID I/O CONTROL PANEL OUTPUTS RS485 TCP/IP MODBUS ALARM ELEVATOR CONTROL REPAIR REPLACE

The ENTRYPASS EP.L3800.PSU Elevator Master Control Panel is designed for elevator access-control applications where authorised users are permitted to access selected floors according to their credentials and programmed access rights. It works as part of a larger ENTRYPASS architecture involving readers, elevator controllers, I/O or output boards, power supplies, management software and the building’s existing lift control system.

SGCCTV – Choicecycle CCTV provides ENTRYPASS elevator access-control troubleshooting, repair, replacement and upgrading in Singapore, including existing EP.L3800.PSU, EP.POB.PSU and networked multi-elevator controller installations.

Model clarification: current ENTRYPASS documentation identifies the networked multi-elevator controller as EP.NE4800.PSU. If an installed unit is labelled EP.N4800.PSU or EP.N5200.PSU, its physical label, PCB revision and existing system documentation should be checked before ordering a replacement.

ENTRYPASS EP.L3800.PSU Elevator Master Control Panel

The EP.L3800.PSU is an ENTRYPASS elevator control panel supplied with a power supply and enclosure.

Current documentation describes it as:

Elevator Master Control Panel with 8-Floor Control + PSU with Casing

The L3800 can form the central interface between the access-control system and the lift-floor control infrastructure.

A typical architecture is:

ACCESS CARD / READER

↓

EP.L3800.PSU

↓

HIO / OUTPUT CONTROL

↓

EXISTING LIFT CONTROL PANEL

↓

AUTHORISED FLOOR ENABLED

The access-control equipment does not replace the elevator’s primary safety controller. It provides security-related floor-access interfacing to the existing lift-control system.

EP.L3800.PSU Key Functions

ENTRYPASS documentation shows the L3800 architecture supporting up to eight HIO nodes, allowing larger floor-control configurations to be designed.

How Elevator Access Control Works

Without access restriction, a person entering a lift may be able to select any normally available floor.

With an elevator access-control system:

PRESENT CARD

↓

CONTROLLER CHECKS USER

↓

ACCESS RIGHTS CHECKED

↓

PERMITTED FLOOR RELAY ENABLED

↓

USER SELECTS AUTHORISED FLOOR

For example:

Employee A → Floors 2, 3, 4

Employee B → Floors 5, 6

Manager → Floors 2–10

Contractor → Floor 3 only

Visitor → Approved floor only

Actual behaviour depends on the lift interface and access-control programming.

EP.POB.PSU Passive Output Board

The ENTRYPASS EP.POB.PSU is a Passive Output Board used within ENTRYPASS elevator-control architectures.

It is particularly relevant to multi-elevator installations.

The documented architecture shows configurations involving:

EP.NE4800 + EP.POB.PSU

for controlling multiple elevator cabs.

The POB provides output interfacing required between the elevator access controller and the corresponding lift-control arrangement.

Multi-Elevator Configuration

For larger buildings with several lift cars, the access-control design becomes more complex.

A system may include:

Central Server

↓

ENTRYPASS Network

↓

NE4800 Elevator Controller

↓

POB Output Board

↓

Individual Elevator Controllers

↓

ELEVATOR CAB 1 / 2 / 3 / 4

ENTRYPASS documentation illustrates both a single POB arrangement serving four elevator controllers and configurations using individual POB boards for separate elevator controllers.

The actual design should follow the existing lift architecture and project requirements.

EP.NE4800.PSU Networked Multi-Elevator Controller

The EP.NE4800.PSU is identified in current ENTRYPASS documentation as a:

Networked Multi-Elevator Controller

This is intended for more advanced networked elevator-access applications.

Compared with a simple standalone floor-access arrangement, a networked controller can form part of a centralised access-management system.

This is useful for:

Commercial Buildings

Office Towers

Factories

Warehouses

Condominiums

Industrial Buildings

Restricted Facilities

Multi-Lift Installations

L3800 vs NE4800

The correct replacement should be determined from the existing system architecture rather than selecting a controller solely by model number.

ENTRYPASS Elevator Access Control Repair Singapore

Older elevator-access systems can develop faults after years of continuous operation.

Common symptoms include:

Card Reads but Floor Button Cannot Press

All Floors Remain Locked

All Floors Become Accessible

One Floor Cannot Be Selected

Several Floors Not Working

Reader Completely Dead

Controller Offline

Communication Failure

Relay Output Failure

Power Supply Failure

Controller Repeatedly Restarts

Software Cannot Communicate with Controller

Lift Access Works Intermittently

Output Board Failure

Battery Failure

RS-485 Communication Problem

Network Controller Offline

A systematic diagnosis is required before replacing the controller.

Card Reader Works but Floor Cannot Be Selected

If the access reader accepts the user’s card but the authorised floor remains disabled, the reader itself may not be faulty.

The troubleshooting path should continue through:

CARD → READER → ACCESS CONTROLLER → FLOOR OUTPUT → LIFT INTERFACE

Possible causes include:

User Has No Floor Permission

Access Level Incorrect

Time Zone Restriction

Controller Offline

Output Relay Failure

HIO / POB Problem

Wiring Failure

Lift Interface Problem

Power Supply Problem

Replacing the reader alone will not correct these faults.

One Floor Not Working

If almost every floor works except one, the main controller may still be operating correctly.

Check:

FLOOR CONFIGURATION → OUTPUT → RELAY → WIRING → LIFT INPUT

Possible causes include:

Incorrect Floor Mapping

Failed Relay Output

Loose Terminal

Damaged Cable

Programming Error

Lift Controller Input Problem

This type of fault can sometimes be repaired without replacing the complete access-control panel.

Multiple Floors Not Working

If a group of floors suddenly becomes unavailable, the technician should investigate whether those floors share the same:

HIO Module

POB

Power Supply

Communication Bus

Controller

or common wiring path.

The failure pattern can provide an important clue to the actual defective component.

EP.L3800.PSU Power Supply Troubleshooting

The PSU is an important part of the controller assembly.

Ageing power equipment can cause:

Controller Rebooting

Intermittent Communication

Reader Failure

Relay Instability

Controller Offline

Random Access Problems

System Failure During Power Interruption

Testing should include the incoming supply, DC output, controller load and backup arrangement where applicable.

A controller should not automatically be declared defective until its power supply has been verified.

RS-485 Communication Troubleshooting

Existing L3800 installations can use RS-485 communications between system components.

RS-485 problems may be caused by:

A/B Polarity Reversed

Loose Terminal

Cable Damage

Poor Termination

Electrical Noise

Communication Converter Failure

Incorrect Device Address

Controller Failure

Expansion Module Failure

When communication is unstable, changing the controller without first checking the RS-485 infrastructure may leave the original problem unresolved.

Repair or Replace ENTRYPASS Controller?

The objective is to identify the defective module rather than unnecessarily replacing the complete installation.

Replacing an Existing EP.L3800.PSU

Replacing an elevator access controller requires more planning than replacing an ordinary card reader.

Before replacement, record and verify:

Existing Controller Model

PCB / Hardware Revision

Floor Quantity

Floor Number Mapping

Reader Configuration

HIO Modules

Output Wiring

RS-485 Addresses

Software Configuration

Power Supply

Existing Lift Interface

Access Levels

User Database

Time Zones

Emergency / Fire Release Arrangement

This information is important because the new controller must reproduce the intended floor-access logic.

Do Not Modify Lift Safety Circuits

Elevator access control is a security interface, not the elevator’s primary safety-control system.

Work involving the lift’s proprietary controller, safety chain or other regulated elevator functions should be coordinated with the appropriate lift contractor and responsible parties.

SGCCTV access-control work should focus on the authorised access-control interface and agreed integration points.

This distinction is especially important during replacement of old elevator-access panels.

ENTRYPASS Platform Migration

An older ENTRYPASS installation does not necessarily require complete replacement.

A staged strategy may be more practical:

Phase 1 — Troubleshoot

Check controller, PSU, communication and outputs.

Phase 2 — Repair

Restore cabling, PSU, communication or individual modules.

Phase 3 — Replace

Replace failed L3800, HIO, POB or compatible controller hardware where appropriate.

Phase 4 — Upgrade

Move obsolete installations toward supported networked ENTRYPASS architecture.

Phase 5 — Integrate

Where required, integrate compatible:

DOOR ACCESS + ELEVATOR ACCESS + CCTV + SECURITY MANAGEMENT

Elevator Access + CCTV Security

Elevator access control determines which floors a credential is authorised to access.

CCTV provides visual evidence of who actually entered the lift lobby or elevator.

A comprehensive security system can therefore combine:

CARD ACCESS EVENT

ELEVATOR FLOOR ACCESS

CCTV VIDEO

This can assist investigation of:

Unauthorised Floor Access

Tailgating

Lost or Misused Cards

After-Hours Access

Security Incidents

Visitor Movement

Restricted-Floor Entry

Compatibility and integration capability depend on the selected access-control and video-management platforms.

Preventive Maintenance for Elevator Access Control

Because lift-access controllers can operate continuously, preventive maintenance should include:

Controller Status

Power Supply Voltage

Backup Battery

Reader Operation

RS-485 Communication

Network Communication

HIO Modules

POB Boards

Floor Relay Outputs

Terminal Connections

Access Database

Floor Permissions

Event Logs

Software Communication

A test should include actual credential-to-floor operation rather than checking only whether the controller’s power LED is on.

10 Frequently Asked Questions (FAQ)

1. What are the ENTRYPASS EP.POB.PSU, EP.N4800.PSU and EP.N5200.PSU?

These are ENTRYPASS access control power supply units designed to provide stable power for compatible facial recognition terminals, controllers, locks and related access control equipment.

2. Why is a dedicated access control power supply important?

A dedicated power supply helps provide stable voltage for connected security devices, improving reliability and reducing the likelihood of interruptions caused by insufficient or unstable power.

3. Can these power supplies be used for facial recognition systems?

Yes. They are intended for use with compatible ENTRYPASS facial recognition and access control systems, subject to the required voltage and current specifications.

4. Can one power supply support multiple devices?

It depends on the total current consumption of all connected equipment. The power supply should always be selected according to the manufacturer’s electrical specifications and system design.

5. What devices can be connected?

Compatible installations may include facial recognition terminals, access controllers, RFID card readers, magnetic locks, electric strikes, exit buttons and other supported ENTRYPASS security devices.

6. What are common symptoms of a faulty power supply?

Possible symptoms include terminals failing to power on, controllers going offline, doors not unlocking, intermittent resets or unstable system operation. These symptoms can also have other causes, so proper troubleshooting is recommended.

7. Can I replace only the power supply instead of the whole access control system?

In many cases, yes. If troubleshooting confirms that the power supply is the cause of the fault and the remaining equipment is functioning correctly, replacing the power supply may restore normal operation.

8. Do these power supplies support time attendance systems?

Yes. They can be used with compatible ENTRYPASS time attendance terminals that meet the electrical requirements of the selected power supply.

9. Can SGCCTV troubleshoot my ENTRYPASS door access system?

Professional AI Facial Recognition Security System for Commercial & Industrial Applications

The ENTRYPASS EP-SFR2100M / FR2100M Facial Recognition Terminal is a high-capacity biometric access control solution designed for organisations requiring fast facial authentication, door access control, RFID card authentication and personnel attendance management.

Powered by AI and deep-learning facial recognition technology, the FR2100M offers a stated recognition speed below 0.2 seconds per user and accuracy above 99%. It also provides face anti-spoofing and data-encryption features for stronger identity authentication. (EntryPass)

With capacity for up to 100,000 faces, 500,000 cards and 150,000 events, the FR2100M is particularly suitable for large offices, factories, warehouses, commercial buildings and enterprise security projects. (EntryPass)

Key Features of ENTRYPASS EP-SFR2100M

The FR2100M provides a strong combination of biometric and card-based authentication:

• 7-inch LCD touchscreen
• 2MP wide-angle camera
• 100,000 face capacity
• 500,000 card capacity
• 150,000 event capacity
• Facial recognition under 0.2 seconds/user
• Stated facial recognition accuracy above 99%
• 0.3 to 3 metre facial recognition distance
• Built-in MIFARE & DesFire card reader
• Face anti-spoofing
• Face mask detection
• Single-person and multi-person recognition up to 5 people
• ISAPI, ISUP 5.0 and TCP/IP IPv4/IPv6 support (EntryPass)

100,000 Face Capacity – Built for Large Organisations

One major advantage of the ENTRYPASS FR2100M is its high user capacity.

With storage for up to 100,000 faces, it can support much larger deployments than conventional small-office biometric terminals. Its 500,000-card capacity also makes it suitable for environments where facial recognition and physical credentials operate together. (EntryPass)

This makes the FR2100M particularly attractive for factories, industrial facilities, corporate campuses, warehouses and multi-department organisations.

Fast Face Recognition – Less Than 0.2 Seconds

Security should not create unnecessary congestion at staff entrances.

EntryPass specifies facial recognition at less than 0.2 seconds per user, with an accuracy rate above 99%. (EntryPass)

Fast authentication is especially valuable at locations where hundreds of employees may arrive or leave within a short period.

Facial Recognition + MIFARE + DesFire

The FR2100M is more than a face reader.

It incorporates a 13.56 MHz MIFARE and DesFire compatible card reader, allowing businesses to deploy facial and card-based authentication according to their security policy. (EntryPass)

For example, different areas can be designed around different authentication requirements depending on the overall access-control configuration.

Face Recognition → Convenient contactless access

RFID Card → Traditional credential access

Face + Card → Higher-security authentication workflow

Face Anti-Spoofing Security

Professional facial recognition requires protection against attempts to fool the authentication system.

EntryPass specifies face anti-spoofing together with data encryption for privacy protection on the FR2100M platform. (EntryPass)

This makes facial recognition more appropriate for controlled-access environments where authentication reliability is important.

0.3 to 3 Metres Recognition Distance

The FR2100M supports facial recognition from approximately 0.3 to 3 metres, giving installers flexibility when positioning the terminal at entrances and access points. (EntryPass)

The combination of a 7-inch touchscreen and 2MP wide-angle camera also provides a user-friendly interface for enrolment and authentication.

Facial Recognition Time Attendance System

When deployed with the appropriate EntryPass access-control platform and attendance configuration, personnel transactions can support time-attendance reporting and workforce management. EntryPass lists Time Attendance Report functionality within its broader access-control platform capabilities. (EntryPass)

This allows organisations to build an integrated environment around:

Employee Identification → Door Access → Transaction Records → Attendance Reporting

The exact attendance workflow should be configured according to the organisation’s HR and access-control requirements.

Contactless Access Control

Face recognition eliminates the need to physically touch a fingerprint reader or always present an access card.

The authorised user’s face becomes an authentication credential, creating a faster and more convenient access-control experience. EntryPass specifically positions its facial recognition platform as a contactless identification solution. (EntryPass)

Ideal Applications in Singapore

The ENTRYPASS EP-SFR2100M is suitable for factories, warehouses, corporate offices, commercial buildings, industrial facilities, schools, laboratories, server rooms, staff entrances, restricted departments and large organisations requiring centralised personnel access management.

EntryPass also positions its wider platform for centralised security and complex project environments, including manufacturing and other enterprise applications. (EntryPass)
