It's not just surveillance.
A few things a camera alone never could give you.
Crime deterrence. A visible tower measurably reduces theft, vandalism and after hours trespass before it starts.
Incident prevention and response. Continuous monitoring flags unauthorised access or safety hazards the moment they happen.
Evidence collection. Recorded footage helps resolve disputes and identify what actually happened, when it matters.
Crew and visitor safety. A safer environment for your team, clients and site visitors, with activity watched and flagged.
Operational efficiency. Real insight into what is happening on site, to optimise workflow and resource allocation.
Three steps to eyes on site.
Requirements assessment
We walk your site, understand what you are protecting and where the blind spots are, then recommend the right setup.
Design and planning
We map tower placement and coverage against your site plan, so every vulnerable point is covered from day one.
End to end delivery
Installation, live monitoring, ongoing support and removal at the end of the job. One team, start to finish.

Canterbury's site surveillance specialists.
SentryAI is a Canterbury based team providing remote surveillance for builders, developers and businesses across the region. We design tailored systems, from a single mobile tower to a fully monitored, multi site programme, and stand behind every install with local, hands on support.
Every job runs through the same process: understand the site, design the coverage, then deliver and support it end to end. Our towers are solar powered by default, and we run equipment refurbishment and recycling programmes to keep gear out of landfill.
Trusted on site.
I called SentryAI because they are local. They responded fast and had the tower installed within days.
