TTA-AI Contact Tracing System

The TTA-AI Contact Tracing System is designed to capture and recognise multiple human faces at once,  It can be used in medium traffic areas where stopping the flow of traffic would be an issue. The device can be used completely stand alone, or data can be stored temporarily before uploading to the cloud for analysis. Our cloud solution will log the faces to aid in contact tracing.

PLEASE NOTE: These products are not Medical Devices and are not intended for the diagnosis, prevention or monitoring of a disease, injury or disability. A TGA approved thermometer must be used to decide if a person has a fever.

By using our cloud service you can search to find when a specific face was captured, and find all other faces that were captured within a specified time-frame to drastically aid in the process of contact tracing. You can then use those time-frames to check against your existing CCTV system to check for contact elsewhere on your premises.



  1. Face recognition and data management to help with contact tracing.

  2. Live thermal imaging sensor display.

  3. Single and multiple target modes.

  4. Recognition works with masks and glasses.

  5. Android operating system.

  6. Built-in black body calibration.

  7. Artificial technology based algorithms guarantee accurate testing results and minimise ambient interference.

  8. Easy “Plug and Play” installation.

  9. Can work either online, entirely offline or can be connected when not in use to sync logging and configuration.

This system can be widely used in:

  • Supermarkets

  • Hotels

  • Airports

  • Schools

  • Kindergartens

  • Childcare

  • Customs

  • Governments

  • Administrative Halls

  • Businesses
