XK300 Contactless Inmate Vital Sign Monitoring

Continuous overdose detection and in-custody death prevention for county jails.

No inmate cooperation required.

Why Facilities Choose the XK 300

Catches what rounds miss. Monitors vital signs 24/7 between wellness checks — the window where most in-custody deaths occur.

No inmate cooperation. Nothing to wear, remove, or tamper with. Works through clothing and blankets automatically.

Immediate alerts. Staff are notified the moment vitals fall outside safe thresholds — not at the next scheduled check.

Documented saves. 160+ facilities. 28 states. Lives saved at Cass County, Walker County, Kenton County, and more.

One call, no subcontractors. Our own engineers install it. Our own team supports it. 24/7.

Closing the Gap

Someone in your facility right now could be in crisis. Not flagged. Not on elevated watch. Medically cleared. Back in their cell.

That's what happened at Cass County Jail in Fargo, North Dakota. An inmate was evaluated and placed in intake. Within minutes, the XK300 issued an alert: abnormal respirations. Staff responded. The inmate was in agonal breathing. He survived.

"Without the benefit of the XK300 sensor," said Captain Andrew Frobig, Cass County jail administrator, "the next scheduled check about 10 minutes later very likely would have been too late."

Ten minutes. That's the gap between your current monitoring and a life saved.

How It Works

The XK300 mounts to the wall or ceiling of a jail cell and reads micro- and nanovibrational patterns in the room — including those produced by the human body — to continuously monitor vital signs.

  • Heart rate — Radar reads chest wall movement through clothing and bedding

  • Respiratory rate — Detects breathing vibrations even when the inmate is still or covered

  • Motion & presence — Automatically switches from motion detection to vital sign monitoring when stillness is detected

  • Threshold alerts — Staff notified instantly when readings fall outside set parameters

6,000–10,000 readings per day. Automated. No staff action required.

Frequently Asked Questions

  • The XK300 was FDA-cleared specifically for correctional use — not adapted from a hospital product, not retrofitted from a consumer device.

    • No inmate cooperation required — nothing to remove, tamper with, or damage

    • Detects through clothing, blankets, and bedding — works regardless of inmate position or behavior

    • Tamper-proof housing — designed for the physical realities of secure detention environments

    • Autonomous vital sign scanning — automatically switches from motion detection to heart rate and respiratory monitoring when stillness is detected

    • Hospital-grade accuracy — FDA 510(k) cleared, the same regulatory standard applied to clinical medical devices

    • Radar emissions 40x safer than standard WiFi — no radiation risk to inmates or staff

    • Cat 6 wired installation — consistent signal in concrete and steel environments where Wi-Fi is unreliable

  • Every XK300 installation is performed by Reassurance Solutions' own full-time engineers. No subcontractors, no third-party handoffs. The installation team is trained specifically for correctional environments and works around your facility's security schedule and operational requirements.

    Full staff training is included with every deployment. After installation: 24/7 direct support, one vendor, one call.

    Deployed in 160+ facilities. Our engineers have worked in maximum security wings, county intake units, segregation housing, and medical observation cells. We've seen your environment. We know how to work in it.

  • No. The XK300 is a ceiling- or wall-mounted radar sensor. It requires nothing from the inmate — no wristband, no compliance, no participation.

  • The XK300 continuously monitors heart rate, respiratory rate, motion, and cell occupancy. It detects changes as small as 0.1 millimeter and generates 6,000–10,000 readings per day.

  • Yes. The XK300 holds FDA 510(k) clearance — the same regulatory standard required for clinical medical devices used in hospitals.

  • A continuous, documented monitoring record directly addresses the "deliberate indifference" standard in wrongful death litigation. Facilities with documented monitoring records are better positioned to demonstrate their duty of care than those relying solely on scheduled rounds. (Note: Reassurance Solutions does not provide legal advice. Consult your county attorney regarding specific liability questions.)

  • Installation timelines vary by facility size, housing configuration, and network infrastructure. Our team will provide a specific timeline during your consultation. Most installations are completed without disruption to facility operations.

  • The XK300 is deployed in county jails, municipal detention centers, and state facilities of all sizes across 28 states. The system scales from a single intake cell to facility-wide deployment.
