Types of Intercom Systems We Offer

Sin Chew Alarm supplies and installs a comprehensive range of intercom and communication systems across Singapore, from simple audio communication solutions for residential properties to advanced IP-based systems for commercial and industrial facilities.

Video Intercoms

Video intercom systems allow users to see and communicate with visitors before granting access, providing an additional layer of security and convenience. These systems are commonly used in homes, condominiums, offices, and commercial buildings where visual verification is important.

Audio-Only Intercoms

Audio intercom systems provide clear and reliable voice communication for visitor management and internal communications. They offer a cost-effective solution for residential, commercial, and industrial environments where visual verification may not be required.

IP-Based Intercom Systems

IP intercom systems utilise existing network infrastructure to support flexible communication, scalability, and system management. These solutions are ideal for larger properties and multi-building environments that require remote accessibility and integration with other security and communication systems.

Integrated Communication Systems

Integrated communication systems combine intercom functionality with access control systems, CCTV systems, alarm systems, IP phone systems, and other security solutions to provide a more unified approach to communication and security management across the premises.

Residential Video Intercom Systems

Our residential video intercom solutions are suitable for HDB flats, condominiums, and landed properties. Residents can communicate with visitors, verify their identity through video, and manage access more conveniently from the entrance to the premises.

Commercial and Multi-Tenant
Video Intercom Systems

For offices, commercial buildings, condominiums, and multi-tenant developments, video intercom systems provide controlled visitor communication and entry management across multiple units or access points. Our IP-based video intercom solutions can support guard station integration, tenant mobile app access, and direct lobby-to-unit communication, helping to streamline visitor handling and property security. These systems can also be integrated with access control systems, CCTV systems, and other security solutions to support a more comprehensive security environment.

Suitable for offices, commercial buildings, schools, healthcare facilities, and industrial premises, these systems support extension dialling, call routing, call forwarding, voicemail, and remote communication capabilities while simplifying future expansion.

Keyphone Systems

Keyphone systems provide reliable internal and external communications for organisations requiring structured call management. Common features include extension dialling, call transfer, paging functions, voicemail, and multi-line call handling. Modern keyphone solutions can also support IP-based communications and mobile integration, providing greater flexibility for today’s workplaces.

Features of Our Intercom Systems

Here’s how our intercom solutions enhance your property’s safety protocols and streamline operational workflows.

Real-Time Awareness and Documentation

Intercom events such as visitor calls, door station activity, and other system notifications can be monitored in real time, helping users respond promptly when attention is required. Depending on the system configuration, audio, video, and event records can also be retained for future review, incident verification, and security management purposes.

Seamless Security Integration

Our intercom systems can be integrated with access control systems, CCTV systems, alarm systems, and other security technologies to support a more unified security environment. This integration enables more efficient monitoring, streamlined operations, and improved coordination across multiple security platforms.

Dedicated Emergency Broadcast Capabilities

Selected intercom and communication systems support emergency broadcasting and public address functions, allowing authorised personnel to communicate important messages to designated areas or multiple locations. These capabilities are particularly useful for schools, commercial buildings, industrial facilities, healthcare institutions, and other environments where timely communication is essential during emergencies or operational events.

Intercom System Applications by Sector

Sin Chew Alarm’s intercom solutions are tailored to the operational realities of each environment, across residential, commercial, and industrial sectors.

Residential Use

Our residential intercom systems support visitor communication and access management for HDB flats, condominiums, and landed properties. Residents can communicate with visitors before granting access, helping to enhance security, convenience, and day-to-day communication at the entrance to the premises.

Commercial Offices

Intercom systems support visitor communication, reception-to-office communications, internal paging, and integration with access control systems for managed entry. These solutions help improve operational efficiency while supporting security and communication requirements within the workplace.

Industrial Environments

Industrial intercom systems provide reliable communication in warehouses, factories, and other operational facilities. Depending on the application, systems can support paging, emergency communication, and integration with wider security and safety infrastructure.

Educational Institutions

Schools, colleges, and training facilities can utilise intercom systems for visitor communication, administrative announcements, internal communications, and emergency broadcasting. These systems help facilitate efficient communication across classrooms, offices, and common areas.

Public Address Systems

Public Address (PA) systems are designed to deliver clear and effective audio communication across buildings, facilities, and public spaces. They enable announcements, background music, emergency notifications, and other audio messages to be broadcast to single or multiple zones from a central control point.

A typical PA system comprises microphones, amplifiers, speakers, mixers, and control equipment configured to suit the size, layout, and operational requirements of the premises. These systems are widely used in schools, offices, commercial buildings, condominiums, industrial facilities, places of worship, and transportation hubs where reliable communication with large groups of people is essential.

Where required, PA systems can be integrated with fire alarm systems, intercom systems, and other building infrastructure to support emergency communications and operational announcements.
