Shelby County Jail Utilizes Remote Heart Rate Sensors on At- Risk Inmates


(COLUMBIANA, AL) Recently purchased remote heart rate sensors in use at the Shelby County Jail have already proved to be potentially lifesaving when the device sounded the alarm about an inmate whose heart rate climbed into a very dangerous zone. Amazingly, the ill inmate was the very first inmate this new product was deployed on.  

Sheriff John Samaniego recently approved the purchase of these specially designed remote heart rate sensors that are being used on certain at-risk inmates held in custody in the Shelby County Jail.  The heart rate sensors are placed in secure bands and then affixed to the at-risk inmates on their ankle or wrist.  The system from 4Sight Labs known as Custody Protect, works by utilizing Bluetooth technology to transmit real-time heart rate data between the sensors and electronic monitoring tablets.  When deputies receive an alarm of an inmate whose heart rate is outside an acceptable range, deputies and medical staff can respond in seconds.  

Sheriff John Samaniego stated, “In my time as Sheriff the inmates who arrive to our jail are increasingly entering our facility off the streets more physically ill and experiencing the challenges of mental illness at a higher rate than anytime I can recall in my career.  This product will be deployed to assist in our mission to administer a safe and secure facility with the inmate’s health and well-being in mind. In the first 48hrs of deploying Custody Protect we are already seeing the benefits the product has to offer.”
