Thermal imaging

Things to consider when using thermal imaging for temperature screening

As society adapts to its new realities, both during and following the current public health crisis, innovative technological approaches to the issue of workplace and public confidence and safety will become increasingly important. Thermal imaging solutions to detect temperatures have risen in notoriety since the spread of COVID-19, for example. Here, Hikvision talks us through the things companies need to consider when using such devices.  

Hikvision’s Temperature Screening Thermal Solution is an example of just such an innovation, one being deployed right now. This is a thermal-imaging based system designed for the rapid, contact-free preliminary detection of elevated skin surface temperatures. Utilising thermal and conventional lenses and sensors, it provides automatic alerts when anyone passing the camera exhibits a temperature in excess of a pre-configured range, allowing them to be clinically measured and assessed in an appropriate environment.

The accuracy of the camera standalone system is ±0.5°C, however it can be enhanced with a blackbody calibrator to increase the accuracy to ±0.3°C and make it capable of screening multiple people simultaneously. It employs AI in order to minimise false alarms caused by heat from other sources, and comes in a variety of formats, including turret and bullet-style cameras, a handheld version, and a metal detector door with integrated thermal camera.

Employee confidence

Hikvision’s temperature screening systems are already being used across a wide range of industries, including hospitals, enterprise head offices, construction sites, government buildings, meat processing plants, nursing homes, food and drug distribution centres, construction sites, and retail stores. In many cases, their use has formed a significant part of the organisation’s strategy for returning employees to work.

However, before any organisation makes a decision about implementing this screening technology, it’s worth being clear about what it can and cannot do.

Thermal screening cameras can:

  • Detect surface skin temperature on a non-contact basis, reducing risk
  • Indicate if that detected temperature falls outside of the pre-configured range, providing a first line of screening for a facility
  • Screen a high volume of people in a short timeframe
  • Provide an audit trail of steps taken to assist with health, safety and welfare compliance

Thermal screening cameras can’t:

  • Detect coronavirus
  • Detect a fever

These aren’t medical devices: they provide preliminary screening in order to offer reassurance and confidence for those entering a facility, with risk for screening staff minimised due to the non-contact nature of the system.

Further considerations for temperature screening

Once a decision has been made to implement a temperature screening solution, a number of factors should be taken into account, including: company approvals, set-up and management guidance, communications to staff (and, if necessary, the wider public), and a data protection assessment.

Also consider:

  • Completion of consent forms for staff
  • A policy for screening visitors to the facility
  • Who will monitor the screening? Will they need special conflict management training?
  • Will visitors be asked to leave or to undergo further clinical screening?
  • Will a specific facility be required for this further screening or for personnel feeling unwell?
