Every time you leave home, there's that nagging worry. Did I lock up properly? Is someone watching the house? You shouldn't have to feel anxious about your own home.
Something happened in the garden last night. Now you're scrubbing through 8 hours of footage trying to find 30 seconds of activity. Life's too short for this.
Your phone buzzes constantly. A cat. Cobwebs. Headlights. After a while you stop checking, which defeats the entire point of having cameras.
Not motion. Not shadows. scOS detects the kind of activity a trained security guard would notice. When your phone buzzes, it matters.
Family, friends, the builder—scOS learns who belongs. No repetitive alerts for familiar faces. Only strangers trigger attention.
Message scOS for pre-edited clips across all cameras, or ask when the bin was last emptied. It's like having staff you can actually talk to.
No hidden fees. No premium tiers. All features included from day one.

Everything you need to know about scOS installation in St Just
Traditional CCTV is a passive observer that merely records your property being burgled; scOS is an active participant that prevents it. While standard systems rely on 'motion detection' that triggers for every spider or gust of wind, our MotionX technology uses advanced AI to identify 'important activity' only, meaning zero false alarms and no need for complex motion masks. Unlike basic systems, scOS doesn't just watch—it reacts. It automatically detects your property boundaries and uses a combination of presence simulation, instant lighting, and escalating voice warnings to deter intruders before they even reach your door. It’s the difference between having a witness and having a digital security guard on duty 24/7.
Yes, scOS is designed to be brand-agnostic and can transform your existing 'dumb' cameras into an intelligent security network. We work with most 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 to ensure compatibility. By connecting your existing cameras to our Intelligence Hub, we can apply our MotionX AI and proactive deterrent features to your current setup, saving you the cost of a full hardware replacement while vastly upgrading your home's intelligence.
scOS employs a sophisticated three-layer deterrent strategy. First is Presence Simulation: when you're away, the system learns your normal internal activity patterns and simulates them, making your home appear occupied to any opportunist watching from the street. Second is our MotionX detection, which identifies suspicious behaviour and recognises people even if they are hooded or attempting to hide their figure. Finally, if a threat is detected within your auto-detected property boundaries, the system initiates an Active Intervention. This includes instant illumination and escalating voice warnings delivered via external IoT speakers. This proactive approach stops criminals in their tracks long before they attempt a break-in.
Your privacy is our priority, which is why scOS is a 100% UK-based operation. Unlike many competitors who ship data overseas, all your video and intelligence data is processed through UK-based data centres and is fully GDPR compliant. We use a hybrid processing model: our Intelligence Hub handles critical AI tasks locally on your property for speed and privacy, only escalating to our secure UK cloud when necessary for remote access or advanced analysis. Your data remains yours; we never sell it, and you have total control over who can access your recordings, which are stored for up to two weeks.
A video doorbell is a reactive tool that tells you someone is at your front door; scOS is a proactive intelligence system that protects your entire property. While doorbells often suffer from 'notification fatigue' due to false alarms and only cover a narrow field of view, scOS monitors your entire boundary with professional-grade wired cameras that can't be jammed like WiFi devices. More importantly, scOS is designed to stop crime before it happens through automated intervention and presence simulation, rather than just providing you with a video of a package being stolen after the thief has already left.
In remote coastal locations like St Just, police response times can naturally be longer than in urban areas. scOS is designed to be your first line of defence. Our escalating response system—including automatic lighting and voice warnings—is designed to stop a crime in progress without needing immediate human intervention. By the time a criminal has been warned by an AI-driven voice that they are being monitored, they almost always flee, knowing that their presence has been logged and the property is actively defended.
Yes. We use professional-grade, wired hardware that is built to withstand the harsh Cornish coastal environment. Unlike wireless cameras that can struggle with signal interference in granite-walled homes or fail in high winds, our wired installations provide a rock-solid connection. Our MotionX AI is also specifically calibrated to ignore the movement of sea birds, wind-blown debris, and heavy coastal mist, ensuring you only get alerted to genuine threats.
scOS is perfect for second homes or holiday lets in St Just. Our Presence Simulation feature makes the property look lived-in even when it's empty, following the patterns of a real person inside. You can check on your property from anywhere in the world via our secure app, and our 'scOS Director' AI can give you a quick update: 'Everything has been quiet at the cottage this week.' It provides total peace of mind for owners who aren't always on-site.
Passive cameras aren't enough. Get AI security that actually prevents crime.
