CCTV, Access Control & Security Systems
Integrated Security Systems for Modern Buildings
Security systems play a key role in protecting buildings, controlling access and monitoring activity across a wide range of environments. Effective security infrastructure is used across commercial premises, residential developments and multi-occupancy buildings, helping to manage entry, deter unauthorised access and provide clear visibility across the site.
Our engineers design and install integrated security systems, including CCTV, door access control and gate entry solutions. Each installation is planned around the building’s layout and usage, allowing systems to be configured to meet the site’s specific requirements.
CCTV
Systems
CCTV systems provide continuous monitoring across buildings, external areas and access points. Camera systems can be positioned to cover entrances, shared spaces, car parks and perimeter areas, giving building operators clear visibility of activity across the site.
We install high-quality CCTV systems using trusted manufacturers such as Hikvision, offering clear image capture, remote viewing and recording functionality. Systems can be configured to suit the building’s size and complexity, with options for both internal and external coverage.
Door Access Control
Systems
Access control systems regulate how individuals enter and move through a building. These systems can be configured using key cards, fobs, PIN entry or mobile access, allowing controlled entry to specific areas.
Our engineers install access control systems from Paxton and Intratone, providing flexible, scalable solutions for a wide range of building types. Access permissions can be managed easily, allowing building operators to control entry for staff, residents and visitors.
Gate Entry & Intercom
Systems
Gate entry and intercom systems provide controlled access at key entry points, particularly within residential developments and secure commercial sites. These systems allow users to communicate with visitors before granting access, improving site security and access management.
We install intercom and entry systems that integrate with wider access control infrastructure, allowing a seamless approach to building security.
Integrated Security Solutions
Security systems are most effective when designed as part of a coordinated approach. CCTV, access control and entry systems can be combined to provide a complete view of site activity and controlled movement throughout the building.
Our engineers work with developers, contractors, and building operators to design and install integrated security infrastructure that aligns with the building’s operational requirements.
Installation, Configuration & Handover
Each system is installed and configured in accordance with the project brief. This includes equipment selection, system layout, installation and setup.
Following installation, systems are tested and configured to confirm they are operating correctly. Guidance can also be provided on system use and management, allowing clients to make full use of the installed infrastructure.
Suitable Applications
Security systems can be installed across a wide range of environments, including:
- Commercial buildings and office spaces
- Residential developments and apartment blocks
- Education facilities
- Healthcare environments
- Mixed-use developments
