Hand-Hygiene and PPE Compliance Monitoring

• Infection Control Officer or Nurse
• Hospital Infection Control Committee Chair
• Nursing Superintendent
• Quality Manager

Infection control teams audit hand hygiene and PPE by direct observation, a few sessions a month per unit. Staff behave differently when an auditor is watching, and the samples are too small to show patterns by shift or location. The infection control committee still needs evidence to target training, dispensers and supplies.

We build a computer vision system that watches defined points such as ICU bed-zone entries, isolation room doors, sanitiser dispensers and OT entrances. It detects events that stand in for hand-hygiene opportunities, such as entering a patient zone, and whether a dispenser was used within a set window, and it checks visible PPE such as masks, caps, gowns and gloves where policy requires them. Processing runs on an edge device inside the hospital. Faces are blurred before anything is stored, and only event data and short blurred clips for audit leave the device. Infection control sees compliance trends by unit, shift and location, not a ranking of individuals.

• Zone-entry and dispenser-use event detection at agreed points
• PPE detection for masks, caps, gowns and gloves at OT and isolation entries
• Edge processing with face blurring before any storage
• Compliance trends by unit, shift and location for infection control
• Optional real-time reminder at OT doors, such as a light or chime
• Sampled blurred clips for auditors to verify detection quality

1. 01Agree points and rulesInfection control and nursing leads choose camera points and define rules, such as dispenser use before entering a bed zone.
2. 02Detect on the edgeEdge devices detect zone entries, dispenser use and visible PPE in real time.
3. 03AnonymiseFaces are blurred and no identity data is stored; only events and blurred audit clips are kept.
4. 04Check confidenceLow-confidence events are left out of metrics or sampled for auditor review.
5. 05Aggregate and reportEvents roll up into compliance trends by unit, shift and location on the infection control dashboard.
6. 06Act on findingsThe infection control committee reviews trends and decides on training, dispenser placement or supply changes.

1. Cameras
   • Dedicated cameras at agreed points
   • Existing CCTV where the angle allows
2. Edge processing
   • Edge GPU device per unit
   • Zone and dispenser event models
   • PPE detection model
   • Face blurring
3. Event pipeline
   • Event store without identity data
   • Blurred clip sampler
4. Analytics and review
   • Compliance dashboard by unit and shift
   • Auditor review queue
5. Governance
   • Access controls and short retention
   • Periodic detection accuracy checks against auditor labels

Infection control auditors verify sampled events and calibrate the system against their own observations, and the committee decides on any action. The system reports at unit level and is not designed to identify individual staff.

• Existing CCTV or video management system where angles allow
• Edge devices on the hospital network
• Infection control or quality dashboard
• Hospital IT security and network policies
• Optional door-side indicator lights or chimes

• Faces blurred on the edge device before any storage
• No cameras pointed at beds, toilets, changing areas or exposed patients
• Reporting at unit and shift level, never individual staff rankings
• Signage and staff briefings before go-live
• Short retention for clips, with access limited to infection control

• Video of staff and patients is personal data under the DPDP Act 2023, so notices, minimisation and short retention are built into the design.
• Supports, but does not replace, the hand-hygiene audits used in infection control programmes and accreditation reviews such as NABH.

• Healthcare & Hospitals

  Pharmacy Shelf and Expiry Monitoring

  Photograph pharmacy shelves, ward stores and crash cart drawers to read batch and expiry dates, find near-expiry and missing items, and flag look-alike medicines stored side by side.

• Hospitality & Travel

  Kitchen Hygiene Monitoring

  Monitor kitchen cameras for missing caps and gloves, uncovered food, open bins, spills and pests at night, with alerts and daily hygiene summaries reviewed by the chef and hygiene lead.

• Manufacturing

  PPE and Safety-Zone Compliance

  Vision models on existing CCTV spot missing helmets, shoes, vests and gloves, and people entering robot cells, press areas or forklift aisles, with clip-backed alerts to supervisors.
