Engineers at Silent Sentinel’s headquarters in Stanstead Abbotts, England, needed new application software for its temperature detection system to process the data from its cameras for display within a security video management system (VMS). A quick turnaround was essential as was the track record of the supplier chosen as Silent Sentinel needed delivery of a working solution in a matter of weeks.

James Longcroft, business development director, Silent Sentinel, said: “Our engineers have worked with Cambridge Pixel in the past and like us, we are both SMEs, they have a reputation for being responsive, flexible and delivering on their promises. As expected, Cambridge Pixel delivered a working solution on time and to budget, and that exceeded our expectations.”

Silent Sentinel’s Covid-19 raised temperature detection system is based on a fusion of daylight and thermal imaging cameras to provide automatic face detection, temperature measurement and alarm reporting capabilities. Cambridge Pixel’s SPx AV software libraries are integral to the new software application that interfaces to the cameras, identifies faces and then measures the skin temperature, giving an alarm if an out-of-range temperature is observed.

The system captures snapshot images from the two cameras for out-of-range temperature detection, and these images can be stored locally or delivered to a wide area control system for further review and action. The system is designed to operate with different thermal and daylight cameras, providing a flexible range of configuration options for Silent Sentinel’s customer base. Optionally, the system can provide full recording of the video data and alarms for later review.

David Johnson, Cambridge Pixel’s CEO, said: “We are really pleased to be involved with the development of this new product to assist with the Covid-19 pandemic. Our SPx AV library of reusable components for camera control, processing and display have enabled us to develop and deliver this customisable software solution in a very short development timeframe.”

The SPx AV software is an integral part of Cambridge Pixel’s SPx suite of software libraries and applications providing highly flexible, ready-to-run software products for radar scan conversion, visualisation, radar video distribution, target tracking, camera control, sensor fusion, plot extraction and clutter processing.

Cambridge Pixel’s technology is used in naval, air traffic control, vessel traffic, commercial shipping, security, surveillance, and airborne radar applications. Its systems and software have been implemented in mission-critical applications with companies such as BAE Systems, Frontier Electronic Systems, Blighter Surveillance Systems, Exelis, Hanwha Systems, Kelvin Hughes, Lockheed Martin, Navtech Radar, Raytheon, Royal Thai Air Force, Saab Sensis, Sofresud and Tellumat.
