The Frustrations Threemilestone Homeowners Know Too Well

View crime statistics

Scrolling Through Hours of Nothing

Something happened in the garden last night. Now you're scrubbing through 8 hours of footage trying to find 30 seconds of activity.

Recording Doesn't Stop Them

Your CCTV captured everything perfectly. Great footage of someone breaking in. But the crime still happened.

Notifications That Cry Wolf

Your phone buzzes constantly. A cat. Cobwebs. Headlights. After a while you stop checking, which defeats the entire point.

Common Questions

Traditional CCTV is a passive observer; it records a crime while it happens but does nothing to stop it. scOS is a proactive intelligence system. While standard systems rely on 'motion detection' that triggers for every swaying branch or passing cat, our proprietary MotionX technology ignores the noise. It focuses exclusively on 'important activity,' such as a person approaching your property or a vehicle pulling into your drive. Because it understands what it sees, it can intervene automatically. Instead of just a notification on your phone while someone is already at your door, scOS identifies the threat at the boundary and uses escalating responses—like lighting and voice warnings—to deter them before they reach your home. It’s the difference between having a witness and having a digital security guard.

In most cases, yes. scOS is designed to be brand-agnostic and works seamlessly with the majority of professional-grade wired IP cameras, including brands like Hikvision, Dahua, Axis, Reolink, and Ubiquiti. During our professional UK installation process, which typically takes 4-6 hours, our engineers will assess your current hardware. If your cameras are compatible, our Intelligence Hub will 'adopt' them, instantly transforming your 'dumb' cameras into an intelligent, AI-powered network. This allows you to upgrade your home security to the latest AI standards without the cost of replacing every piece of hardware. We prefer wired connections over wireless because they are more reliable and cannot be defeated by the Wi-Fi jamming devices often used by modern burglars.

scOS uses a sophisticated three-layer approach to deterrence. First is Presence Simulation: the system learns your home's normal activity patterns and simulates them when you're away, making it appear occupied to anyone watching from the street. Second is our MotionX detection, which identifies a person the moment they cross your property boundary—even if they are wearing a mask or hood. Finally, the system initiates an Active Intervention. This isn't just a recording; it’s a live response. External IoT speakers deliver clear AI voice warnings while smart lighting illuminates the intruder. By removing the 'cloak of darkness' and making it clear they have been spotted by an intelligent system, scOS forces criminals to move on to an easier, less protected target.

Your privacy is our priority. Unlike many security companies that outsource data handling to international servers, scOS is 100% UK-based. All your video data and AI processing are handled between your local Intelligence Hub and our secure UK-based data centres. We are fully GDPR compliant, meaning your data belongs to you and is never sold or shared with third parties. You have total control over your recordings, which are stored for up to two weeks and accessible only by you through our secure app. By keeping the intelligence local and the cloud storage within the UK, we ensure that your home's security data remains under the protection of British privacy laws.

A video doorbell is a reactive tool; it tells you who is at the door once they’ve already arrived. By that point, a determined criminal may have already checked your windows or tried your side gate. scOS provides whole-property intelligence. It monitors your entire boundary, not just the front door, and it is designed to stop a crime before it happens. While a doorbell might give you a video of a package being stolen, scOS detects the individual as they step onto your driveway and uses proactive deterrents to ensure they never get close enough to touch your property. It’s a comprehensive security solution versus a simple digital peephole.

Threemilestone is a busy village with a lot of footfall, especially near the A390. Traditional motion sensors would be constantly triggered by passing pedestrians. scOS uses MotionX technology, which ignores public areas and only focuses on 'important activity' within your property boundary. It understands the difference between someone walking past on the pavement and someone actually entering your driveway or garden. This means you get zero false alarms while maintaining total security for your home.

Yes. Our Person Recognition technology is built on behavioural patterns. It learns to distinguish between the people who live in your home, regular visitors like delivery drivers, and total strangers. In a community like Threemilestone, this means you won't get constant alerts for the postman, but the system will immediately flag if an unknown person is loitering near your property or exhibiting suspicious behaviour. It’s about providing relevant intelligence, not just a stream of notifications.

Absolutely. For residents who work in Truro or at the Royal Cornwall Hospital, scOS Director is an invaluable tool. It is a conversational AI that allows you to ask natural questions about your home while you're away. You can ask, 'Did the kids get home safely?' or 'Has anyone been near the garage today?' The AI understands the context of your property and provides instant answers based on its analysis of the day's activity. It’s like having a dedicated security guard you can talk to at any time.
