Can CCTV and access-control cabling share a project with the data network?

Detailed answer

What this means for your project

CCTV, access control and data networks often share containment zones, cabinets, PoE infrastructure and construction interfaces. They may still have different resilience, segregation, device, retention and commissioning requirements. A coordinated design identifies device locations, bandwidth and power needs, controller or recorder positions, containment ownership and handover responsibilities. LGN installs the physical infrastructure and works with the relevant specialist for system configuration and commissioning boundaries.

The appropriate specification and delivery method still depend on the site, programme and evidence available. LGN can review those constraints before recommending a practical next step.

Coordinate shared routes without blurring responsibilities

These systems may use common containment and PoE switching, but camera, door and general network requirements are not interchangeable. Device locations, resilience, bandwidth, power, security zones and controller positions should be documented separately.

Interfaces to resolve early

• Who supplies, mounts, configures and commissions each device?
• Where do recorders, controllers, power supplies and network switches sit?
• Which doors or cameras need resilient paths or backup power?
• What containment, penetrations and fire stopping are required?
• What test evidence belongs in the final handover?

LGN’s role

LGN delivers the physical infrastructure and can coordinate installation interfaces with the relevant security or IT specialist. Clear scope boundaries protect commissioning and make faults easier to assign, while coordinated routes reduce duplicated access work and clashes with other trades.
