Overview
Restaurants lose revenue and repeat business to problems that are preventable but hard to catch in real time: a guest who waits too long to order, an upsell moment missed because staff are stretched, a table left dirty after guests leave, or a guest waving across the room just to ask for the bill.
These aren't failures of effort — they're failures of visibility. We designed and developed an AI table monitoring and staff alert system that gives every table an always-on layer of awareness, without adding headcount or replacing staff. It runs live in the restaurant, rolled out one table first so the full system was proven on the floor before scaling up.
The challenge
No manager can watch every table, every second, across a full service. The restaurant needed a way to:
- Know the moment a table needs attention — seated, ready to order, food served, ready to pay, empty.
- Let guests ask for service silently, without having to catch a staff member's eye.
- Tell the right person, not everyone — so alerts help staff instead of distracting them.
- Increase order value naturally, without pushy, scripted selling.
- Do all of it responsibly — many "smart restaurant" systems rely on facial recognition or staff monitoring, which brings real regulatory and reputational risk.
What we did
Mapping the whole guest journey
We mapped every step of a guest's visit and decided, for each one, whether the guest, the system or the staff acts:
| Moment | What the system does | Staff action |
|---|---|---|
| Guest seated | Checks the menu has been placed within a minute | Places the menu if needed |
| Guest taps "ready to order" | Sends an instant alert | Takes the order |
| Order placed | Generates a tailored upsell suggestion | Relays it in their own words |
| Food served | Starts a 10-minute timer | Checks on the food when it ends |
| Guest taps "ready to pay" | Sends an instant alert | Brings the bill and takes payment |
| Table empty | Detects it a minute after payment | Cleans the table |
Most of the journey runs automatically; staff stay in control of every guest interaction.
Camera, POS and contactless tags working together
A WiFi camera streams the table over RTSP, and our computer-vision logic detects table-level events such as a guest being seated, the menu being placed and the table becoming empty. The restaurant's Epos Now till is connected through webhooks, so order and table status stay in sync in real time. Two contactless tags on each table — ready to order and ready to pay — let guests signal silently with a single tap.
AI upsell suggestions staff can use naturally
An AI suggestion engine reads the live order and suggests a natural next step — a drink to go with the meal, or a dessert at the right moment. Staff hear the suggestion and offer it in their own words, so the conversation stays human rather than scripted.
Spoken alerts to the right earpiece
Every event becomes a short spoken alert. In the first release we deliver alerts through Zello's push-to-talk platform to staff Bluetooth earpieces, using text-to-speech and audio streaming. This let us validate the detection and AI logic quickly, without first building custom mobile infrastructure. A purpose-built Android app is planned for later phases, giving full control over routing, voice generation and offline reliability.
Privacy by design
Every design decision was made with data protection in mind from the outset:
- No facial recognition of any kind, at any stage.
- No emotional, mood or behavioural analysis of staff.
- Cameras detect operational events at table level only — never to identify or profile individuals.
This keeps the system aligned with UK GDPR data-minimisation principles and the workplace-monitoring provisions of the EU AI Act.
A phased roadmap
- Phase 1 — Build & launch: one table, live in the restaurant, Zello-based alerts, plus a short trial to gather real usage data and staff feedback.
- Phase 2 — Pilot rollout: multiple tables and the custom Android alerting app.
- Phase 3 — Full deployment: the whole restaurant, with ongoing support.
Why choose SystemLoom
We combine computer vision, POS integration, AI and real-time communication into one system that fits how a restaurant actually works — and we build responsibly, keeping privacy and regulation in the design rather than bolting them on later. Start small, prove it works, then scale.
The results
- The complete guest journey on one table: menu check, ready-to-order signal, AI upsell suggestion, food check-in, ready-to-pay signal and table-clean alert
- Guests request service silently with contactless tags — no waving or searching for staff
- Spoken alerts routed to the right staff member's Bluetooth earpiece in real time
- AI-generated upsell prompts that staff relay in their own words — natural, not scripted
- Privacy by design: no facial recognition and no staff monitoring, built with UK GDPR and the EU AI Act in mind
- Built, developed and running live in the restaurant, ready to scale across more tables
