Wireless IP transceivers can solve a practical problem on changing construction sites: getting IP video between locations where permanent cabling is difficult, disruptive or likely to be moved. A point-to-point wireless bridge can connect cameras or a remote network position back to the recorder without trenching, provided the radio path, bandwidth, mounting and power are properly planned.

Construction-site crime remains costly. The Secured by Design construction site security guide cites estimated industry losses of around £800 million a year from crimes including theft, criminal damage, arson and antisocial behaviour. That figure should not be treated as theft losses alone. Temporary layouts, valuable equipment and periods when a site is unoccupied make layered security important throughout the project.

Why wireless can suit a live site

Permanent cable is still the right choice where a protected route is available. On active sites, however, groundworks, changing compounds and temporary welfare facilities can make fixed routes impractical. Wireless links can be repositioned as the site develops, and the equipment can potentially be reused on another project.

Our guide to wireless IP transmission for CCTV explains the main design considerations. A clear radio path matters, particularly at 5.8 GHz, but installers should also allow for interference, available throughput, mounting stability and future changes to hoarding or stored materials.

Getting the link right first time

Ofcom's current rules are important when specifying equipment. Fixed Wireless Access equipment in the 5725–5850 MHz band is now licence exempt, and the regulations implementing the change are in force. Equipment must still comply with the applicable technical conditions and interface requirements, so check the licence exempt status before deployment.

Power is the other half of the design. Follow the same planning described in how to spec stable power for multi camera jobs and PoE power budgeting. Where electrical infrastructure was an afterthought, unreliable power can undermine an otherwise well-designed wireless link.

Specifying CCTV around the link

A 2 camera CCTV system may be enough for a small gate and compound, while 16 camera CCTV systems can suit larger layouts where the coverage requirements justify them. ANPR cameras can support vehicle-access management and provide registration information within recorded footage. CCTV monitors can provide a suitable local viewing point for site teams.

Where the risk assessment justifies them, active deterrence cameras can add light or audio-warning functions. Audio needs particular care because ICO guidance describes audio recording as especially intrusive and says continuous recording will usually be difficult to justify.

Visible CCTV signage is also required where people are being recorded. ICO guidance says signs should make clear that CCTV is operating, why it is being used and who can be contacted with queries. The principles in CCTV signage and privacy for UK sites apply to temporary installations too. Related seasonal considerations are covered in summer security for schools and industrial estates.

Before handover, test live and recorded video at the receiving end, check the wireless link under normal site conditions and document the configuration. This supports the approach described in preventing time sinks on site.

FAQs

Do wireless CCTV links always need line of sight?

A clear path is strongly preferable for reliable point-to-point links, particularly at 5.8 GHz. Obstructions and interference can reduce performance, so the proposed link should be surveyed rather than assumed.

Do I need an Ofcom licence for 5.8 GHz FWA equipment?

Compliant FWA equipment operating within the current conditions for the 5725–5850 MHz band is now licence exempt. Installers should still check that their equipment meets the applicable technical requirements.

Can wireless links replace all CCTV cabling?

No. Cameras still need suitable power and local connectivity, and wired links may remain preferable where protected permanent cable routes are available.
