SEZO TM directly affects the safety of participants in mass running events as well as those who prefer running alone. SEZO TM not only makes it easier to keep track of the runners’ current positions, but also to contact them through a built-in loudspeaker, enabling voice messages to be sent both to selected or all users (in case of a mass event; informing e.g. about an upcoming storm).

The built-in accelerometer allows to detect a runner’s accident – after recording an impact or a fall, the device activates an audible alert once, and an alarm diode placed on the device sends light signals. At the same time, in the case of mass events, the organiser receives information about a potential threat. All this happens without the participation of a runner, so it is also effective in case of loss of consciousness.

If, after activating the CRASH function, the device detects movement (thanks to GPS), the alarm diode stops blinking and the organizer receives information about cancelling the alarm.

The use of the LTE-M system in the SEZO TM device provides better coverage even on difficult terrain, and thus greater reliability.
