Project genesis
A problem that required a solution
The Prison Service, Police, Border Guard, facility security, hospital staff — thousands of people in Poland work every day in conditions of direct threat. Despite this, most of them do not have a personal alarm system that allows them to call for help immediately.
Existing solutions rely on extensive network infrastructure, are expensive to implement and maintain, or simply do not address the specifics of working in operational conditions — where every second counts and there is no time for procedures.
Daily threat without protection
Officers and uniformed service personnel are exposed to aggression from inmates, detainees and patients. Incidents involving staff are increasing year by year, and traditional means — radio, phone, physically reaching an alarm point — do not provide immediate response in a crisis situation.
Infrastructure as a barrier
Alarm systems available on the market rely on extensive network infrastructure — LAN, Wi-Fi, structured cabling. In many facilities, especially older prisons, hospitals and police stations, such modernization is technically difficult or financially unattainable.
Response time decides
In a situation of attack or threat to life, every second matters. Procedures based on radio or telephone communication introduce delays that can cost an officer's health or life. A system is needed that works in a fraction of a second — with a single button press.
Costs block implementations
High costs of purchasing, installing and servicing traditional solutions mean that most facilities give up on implementing a personal alarm system. Uniformed service budgets do not allow for network infrastructure expansion in every facility — a solution that works without it is needed.
OSA was born from the conviction that personnel safety should not depend on Wi-Fi availability, the budget for building cabling, or complex device operation procedures. What was needed was a solution that is simple to use, independent of infrastructure and ready for deployment in any type of facility — from a prison to a hospital emergency room.
System architecture
Four layers, one goal
From pressing the button to dispatching the response team — in seconds. The entire signal flow operates without network infrastructure in the facility.
OSA Terminal
Wearable transmitter
The officer presses the alarm button on the wearable transmitter. The device immediately sends a BLE 5.0 signal containing the transmitter ID, alarm type (loud or silent) and battery level. No procedures, no unlocking, no screens — one action.
Repeater
Range extender
Repeaters placed throughout the facility receive the signal and relay it in cascade to subsequent devices in the network. Automatic retransmission and buffering guarantee alarm delivery even if a single repeater fails. No device limit — the system covers every zone of the facility.
Gateway
Network gateway
The only point of contact between the system and network infrastructure. Converts the BLE signal to a network protocol and forwards the alarm to the monitoring system via WiFi, Ethernet or 4G — depending on the available connection in the facility.
Monitoring system
Operator dashboard
The operator receives a real-time alert with officer identification, alarm type and approximate location based on RSSI. The dashboard enables immediate dispatch of the response team and incident documentation.
Key advantage of OSA architecture
The system does not require network infrastructure in the facility. Communication runs exclusively through energy-efficient BLE 5.0 — no Ethernet cables, no Wi-Fi access points, no fiber optics. The only point of contact with the network is the gateway, which can use any available connection: WiFi, Ethernet or 4G.
Partners and cooperation
The OSA system is the result of cooperation with leading scientific institutions and proven technology partners.
