Akuvox S535 Modular Video Door Phone

The Akuvox S535 Door Phone is a modular smart video intercom designed to combine premium entrance presentation, flexible access control and future expansion in a single platform. Featuring an aluminium front panel, 5-inch IPS touchscreen and 2MP wide-angle camera, the S535 provides an intuitive visitor interface for apartment buildings, offices, schools, commercial facilities and other controlled-access environments.

Its modular architecture allows additional functionality to be added when required, making the S535 particularly suitable for projects where access-control requirements may evolve over time.

Premium 5-Inch IPS Touchscreen

The S535 features a 5-inch IPS LCD touchscreen integrated into a premium aluminium front panel.

The large display provides visitors with a clear and modern interface for intercom and access functions, while the streamlined enclosure complements contemporary residential and commercial entrances.

2MP Wide-Angle Camera with HDR

A built-in 2-megapixel camera provides a broad field of view for entrance monitoring and video communication.

Camera coverage includes:

• 116° horizontal field of view
• 62° vertical field of view
• HDR imaging
• Automatic night mode

HDR helps maintain image detail in difficult lighting conditions, while automatic night operation supports visibility around the entrance after ambient light levels fall.

The camera can also operate continuously as part of the site’s compatible security and monitoring configuration.

Akuvox S535 Door Phone Access Control

Multiple authentication methods allow residents, staff and visitors to use the credential type most appropriate to the site.

Supported access methods include:

• Facial recognition
• RFID cards
• PIN codes
• Bluetooth Low Energy
• QR codes

QR-code access can be particularly useful for temporary visitors, while facial recognition and BLE provide convenient contactless options for regular authorised users.

Full-Duplex IP Audio

Full-duplex two-way IP audio allows visitors and occupants to communicate naturally without requiring push-to-talk operation.

Echo cancellation helps maintain clearer communication between the entrance and compatible receiving devices.

This makes the unit suitable for busy entrances where reliable two-way communication is required throughout the day.

Modular Expansion

One of the key advantages of the S535 is its expandable architecture.

Optional functional modules can add capabilities such as:

• 4G/LTE connectivity
• Fingerprint recognition
• Induction loop functionality

This modular approach allows additional functions to be incorporated without necessarily replacing the complete door station.

LTE capability can provide additional deployment flexibility for appropriate sites, while fingerprint recognition adds another biometric authentication option. An optional induction loop can assist communication accessibility for visitors using compatible hearing aids.

SIP and ONVIF Integration

SIP support allows the S535 to integrate with compatible IP communications and intercom platforms.

ONVIF support provides additional interoperability with compatible:

• Network video recorders
• Video management systems
• IP surveillance platforms
• Third-party security systems

This allows the door station to form part of a broader IP communications and security environment rather than operating as an isolated access device.

Built-In Tamper Alarm

An integrated tamper alarm provides an additional security measure for the entrance terminal.

This is particularly useful for public-access and high-traffic locations where attempted interference with the intercom may need to be detected as part of the security system.

IP66 and IK08 Protection

The S535 is designed for demanding indoor and outdoor entrance locations with:

• IP66 environmental protection
• IK08 impact resistance

IP66 provides dust-tight protection and resistance to powerful water jets, while IK08 provides protection against mechanical impact.

Its specified operating range of -40°C to +55°C allows deployment across a broad range of environmental conditions.

Flush or Surface Mounting

The unit can be installed using either:

• Flush mounting
• Surface mounting

This provides greater flexibility for new construction, retrofit projects and different architectural requirements.

Scalable Residential and Commercial Access

The combination of multi-credential authentication, modular expansion and third-party integration makes the S535 suitable for applications including:

• Apartment buildings
• Residential developments
• Office buildings
• Schools
• Commercial facilities
• High-traffic entrances
• Controlled-access sites

Its expandable design also allows system functionality to be adapted as site requirements change.
