DSSL Group delivers nationally supported door entry and intercom systems designed to enhance building security, resident safety and controlled access management. We support housing associations, property management companies, local authorities, car parks, hotels and facilities management teams across the UK with installation, upgrades, planned maintenance and reactive repair services.

Door entry systems play a critical role in safeguarding residents, protecting communal areas and managing authorised access. DSSL designs and maintains both audio and video intercom systems, ranging from single-entrance installations to large, multi-block estates with centralised management capability.

We are accredited partners with Videx and CAME-Entrotec, both recognised as market leaders within the social housing and residential environment. These partnerships enable us to deliver robust, resident-focused systems that are reliable, scalable and suited to high-density housing estates.

For more complex or enterprise-level environments, DSSL partners with Zenitel and Commend to deliver IP-based, networked intercom solutions suitable for commercial buildings, control rooms, transport environments and high-security sites. These platforms support advanced features such as centralised management, integration with access control and CCTV, and full IP infrastructure deployment.

While we maintain close relationships with these leading manufacturers, DSSL is not restricted to any single brand. Our engineers are experienced in working across a broad range of legacy and modern systems, allowing us to support mixed estates and provide cost-effective upgrade pathways without forcing unnecessary full replacements.

Our services include:

• New system design and installation
• Block-wide and estate-wide upgrades
• Hardwired, IP and 4G GSM solutions
• Integration with access control and CCTV platforms
• Accessibility-focused design for elderly and disabled residents
• Planned preventative maintenance programmes
• Reactive call-out and fault diagnosis

All works are delivered by directly employed PAYE engineers, ensuring consistent standards, accountability and technical competence across every project.

From residential tower blocks and supported living schemes to commercial and hospitality environments, DSSL provides door entry solutions that are secure, reliable and aligned with operational safeguarding requirements.
