Every food plant has hygiene rules at the door: hairnets on, beard nets where needed, hands washed properly, gloves after the wash. The hard part is knowing whether they are followed on every shift, not just on audit day. AI vision at hygiene stations checks each entry, coaches people by voice when something is missed and reports anonymous compliance rates by shift. See it running at a real entry point in a short GMP vision demo.
Check Every Entry, Coach on the Spot, Report Without Names
iFactory GMP Monitoring uses cameras at hygiene stations to confirm PPE and handwash duration. It gives friendly audio coaching when a step is missed and logs anonymised compliance rates by shift for QA.
The Personnel Rules a Camera Can Help Verify
In the US, 21 CFR 117.10 sets the hygiene rules for people who work with exposed food, food-contact surfaces or packaging. They must wear suitable outer garments, wash hands thoroughly before starting work, after every absence from the work station and whenever hands may be soiled, keep gloves intact and clean, remove or cover jewellery and wear effective hair restraints such as hairnets and beard covers. Other markets and GFSI schemes set similar rules. Cameras can't check everything on that list, but they can check the visible parts, every time. Ask our support team which rules your stations can cover.
Station by Station: Checks, Rules and Coaching
A hygiene station is usually a short sequence: PPE on, hands washed and dried, sanitiser, gloves, then the door or turnstile. The camera follows the same sequence. Each check has a rule you set to match your own SOP, and a short coaching line that plays if the step is missed. The matrix shows typical settings. Configure your own in a station setup session.
How the Handwash Timer Works
FDA Food Code guidance for food service, often used as a benchmark, calls for a handwash of at least 20 seconds, with 10 to 15 seconds of vigorous scrubbing. Many manufacturing plants set their own SOP at that level or longer. The camera times the steps that matter, not just the time someone stands at the sink. A person holding hands under running water without soap and scrubbing does not count as a good wash. Set the timer to your SOP with help from our hygiene specialists.
Compliance Data Without Watching People
Workers are right to be wary of cameras. The aim is to check that a hygiene step happened, not who did it. Treat images of people as personal data under privacy law such as the GDPR, and in many European countries agree the system with the works council before it is installed. iFactory is designed around those expectations: it detects PPE and hand actions, not identities, and reports rates by station and shift. Plan the privacy setup with our support team.
Find the Problem Stations, Not the Problem People
Low compliance usually points to a station issue: a slow soap dispenser, a missing mirror, a queue at shift change. iFactory shows where and when steps are missed, so QA can fix the cause.
How Coaching Works at the Station
Coaching is short, polite and immediate. People respond better to a quick reminder at the sink than to a talk from a supervisor a week later. The steps below show what happens when a check is missed. Coaching lines can be set in several languages to match your workforce, and volumes can be tuned to the noise at each station. Hear sample coaching in a live walkthrough.
What an Anonymised Compliance Report Shows
The daily report answers three questions: how many entries met every rule first time, which checks are missed most and where and when the misses happen. The figures below are an illustrative example from one high-care entry. They show how the report points to a specific shift, station and check, rather than a general "do better" message. Get a sample report for your own stations from our support team.
Four Station Changes That Often Lift Compliance
When the report shows a low rate at one station or shift, the cause is often physical rather than personal. These four changes are common, low-cost responses, and the camera data shows whether each one worked. Test them one at a time so the effect is clear. Review your station layouts with our hygiene team.
Three Plants, Three Different Setups
The same system is configured differently depending on the product and the hygiene zones. These three examples show typical setups. They are illustrations, not case studies, and your own setup should follow your HACCP plan and SOPs. Discuss your zones in a zoning review.
A Station Setup Sheet for Each Entry Point
Fill in one sheet per hygiene station before installation. It turns your SOP into settings the camera can use and makes sure QA, production and worker representatives agree on what is checked. Ask for a blank version from our support team.
What Works, and What to Avoid
Plants that get lasting value from hygiene monitoring treat it as a tool for better stations and better habits. Plants that treat it as surveillance tend to see trust fall and workarounds appear. If you want a second opinion on your rollout plan, talk to our GMP team.
- Agree the scope with workers and their representatives first
- Fix station layout, sinks and dispensers before blaming people
- Match every check to a written SOP step
- Use friendly coaching in the workforce's languages
- Share the same reports with workers and managers
- Identifying or ranking individual workers
- Adding checks that aren't in the SOP
- Cameras outside hygiene stations
- Keeping images longer than needed
- Stopping manual GMP audits entirely
Cameras, Audio Coaching and AI Server in One Package
iFactory delivers GMP Monitoring as a turnkey bundle. A pre-configured NVIDIA AI server ships racked and ready with the hygiene models, coaching audio and reporting pre-loaded, so images are processed and blurred on site and never leave the plant unless you choose. You rack it, plug in power and Ethernet, and the AI is live. To scope it for your entry points, request a turnkey quote.
