Sensor Integration

Vigil integrates with proximity sensors for automatic verification, fall detection, and patient monitoring.

Sensor Types​

Sensor Hub​

The sensor hub is an on-premise device that:

  • Connects room sensors and wearables to Vigil
  • Provides local processing for low-latency events
  • Communicates securely with Vigil's cloud

Each facility needs at least one hub.

Room Sensors​

UWB (Ultra-Wideband) sensors mounted in patient rooms:

  • Detect staff and patient proximity
  • Provide distance measurements (within ~1 foot accuracy)
  • Support multiple simultaneous tags

One sensor per room is typical.

Wearable Tags​

BLE/UWB tags worn by patients:

  • Enable precise patient tracking
  • Support fall detection
  • Detect bed exits
  • Monitor for elopement

Assign one tag per patient as needed.

Hardware Setup​

Installing the Hub​

  1. Connect hub to facility network
  2. Power on the hub
  3. Note the hub's MAC address or serial number

Registering the Hub​

  1. Navigate to Settings > Devices
  2. Tap Add Device
  3. Select Sensor Hub
  4. Enter hub identifier
  5. Generate API key
  6. Configure hub with the API key

Installing Room Sensors​

  1. Mount sensor in patient room (ceiling or wall)
  2. Power and network connect the sensor
  3. In Settings > Devices, add the sensor
  4. Associate with the hub and room

Configuring Wearables​

  1. In Settings > Devices, tap Add Device
  2. Select Wearable Tag
  3. Enter device identifier
  4. Associate with the hub

Assign wearables to patients from the patient detail screen.

Proximity Verification​

With sensors configured, Vigil automatically:

  1. Detects when staff enter patient rooms
  2. Records proximity events with distance
  3. Uses events for observation verification

Staff see "Proximity Verified" when documenting if a recent event exists.

Fall Detection​

Room sensors detect falls by analyzing:

  • Rapid downward motion
  • Impact patterns
  • Position changes

When a fall is detected:

  1. Alert created immediately
  2. Push notification sent to assigned staff
  3. Alert escalates if not acknowledged

Bed Exit Monitoring​

During configured nighttime hours:

  1. Sensors monitor patient position
  2. Bed exit triggers an alert
  3. Staff notified to check on patient

Configure nighttime hours per unit.

Elopement Detection​

For patients with elopement risk:

  1. Assign a wearable tag
  2. Configure geofence boundaries
  3. If patient crosses boundary, alert triggers

Geofencing requires room sensors at exit points.

Device Management​

Device Management

Viewing Device Status​

Navigate to Settings > Devices to see:

  • All registered devices
  • Online/offline status
  • Battery level (wearables)
  • Last seen timestamp

Device Health Alerts​

Vigil alerts when devices have issues:

  • Device offline for extended period
  • Battery low on wearable
  • Hub communication failure

Troubleshooting​

Device offline:

  • Check power connection
  • Verify network connectivity
  • Restart the device

Proximity not detecting:

  • Ensure room sensor is associated with correct room
  • Check staff badge/device has BLE enabled
  • Verify sensor has line of sight

Wearable not tracking:

  • Check battery level
  • Verify assignment to patient
  • Ensure within range of room sensors

API Access​

Sensor hubs communicate via the Sensor Ingest API.

For custom integrations, see the API documentation.
