Introduction
Every year, thousands of inmates die while incarcerated.1 ~40% of these deaths are the result of cardiovascular or respiratory illness, overdose, detox, or suicide.1 Although guards perform frequent checks, it can be all too easy for a serious health event to happen between these times. Siu Lam Psychiatric Center in Hong Kong knew they needed a better way to help protect their at-risk inmates. That’s why, in partnership with security solutions company GuardForce and technology developer Cherrypicks, they turned to Xandar Kardian sensors for help.
Trial Implementation
Siu Lam Psychiatric Center wanted to augment their guards’ careful surveillance with an automated, continuous, contact-free solution. The facility installed four XK300 ultra-wideband (UWB) radar sensors in single-occupancy cells of at-risk inmates — continuously monitoring the inmates’ vital signs like heart and respiratory rate.
Life-Saving Results
In July 2021, just moments after a prison staff patrol, an inmate fainted and collapsed in his cell. The XK300 sensor detected rapid deterioration of his vital signs, and immediately sent an alert to duty staff. Thanks to this early detection, prison staff was able to intervene right away, administer aid and save the inmate’s life.
Expanding the Impact
Hong Kong Correctional Services are now deploying more Xandar Kardian sensors throughout additional locations to help protect more inmates and support busy guards.
Together with Guardforce HK, Xandar Kardian was awarded the Silver Medal by the prestigious International Exhibition of Invention Geneva for “Life Saving Technology for Inmates.”
Meet the XK300
The XK300 uses radar monitoring to track heart rate, respiratory rate, motion and presence. In fact, it is the first commercially available medical device cleared by the FDA to do so. Our radar can sense through blankets, clothing, furniture and even drywall to detect micro vibrations from the body — safely. Discover how it can make a difference for your inmates and your staff.

It’s a significant step towards guaranteeing inmate safety.”
