CONTROL4 UNIFI: Setting Up UniFi Face Detection and LPR (Licence Plate) Detection on Unifi Protect

CONTROL4 UNIFI: Setting Up UniFi Face Detection and LPR (Licence Plate) Detection on Unifi Protect

Preparation

  1. Ensure that our UniFi Protect Controller driver is configured
  2. Ensure That the UniFI Controller and driver is running the latest update
  3. Ensure that both API and Login Connection Status is OK
  4. Ensure that Display Diagnostics shows no connection errors
  5. The Cameras must support the appropriate AI capabilities. If LPR and Face Detection is not supported, you can use a device such as a AI Port to add support
  6. For Face Recognition to work correctly, ensure faces are correctly tagged in UniFi Protect. Licence plates do not require tagging 

Programming Using Licence Plate Recognition

To Program for Licence Plate recognition, we offer a few different variables which can be programmed against:
  1. LAST_LPR_DETECTED: Shows the Last Licence plate number which has been detected. If the Plate has been tagged with a name in UniFi Protect, the name might be used instead
  2. LAST_LPR_DETECTED_DATE: Shows a human readable date for when the Licence Plate was detected
  3. LAST_LPR_DETECTED_LINK: Provides a web address to the event. Normally not needed 
  4. LAST_LPR_DETECTED_TIMESTAMP: Computer readable timestamp for when licence plate is detected
It is recommended to use Variable agent  (found under Agents)  to display the contents of the variables during testing, to identify what to program off. 


Some example programming is below using the LAST_LPR_DETECTED_TIMESTAMP as a trigger for the programming


Programming Using Face Recognition

Unlike LPR, Face detection requires that faces are tagged with a name in the UniFi Protect software

To Program for Face Recognition, we offer a few different variables which can be programmed against:
  1. LAST_FACE_DETECTED: Shows the last face which has been detected. The face must be tagged in UniFi Protect
  2. LAST_FACE_DETECTED_DATE: Shows a human readable date for when the face was detected
  3. LAST_FACE_DETECTED_LINK: Provides a web address to the event. Normally not needed 
  4. LAST_FACE_DETECTED_TIMESTAMP: Computer readable timestamp for when face is detected

It is recommended to use Variable agent (found under Agents) to display the contents of the variables during testing, to identify what to program off.

An example of programming is below

For convenience, you can set the Auto Create Events for Faces to Automatic. This will create Events automatically for each tagged face as they are detected
