GUARD is the combination of a necklace and an anklet, which together form a security system. In the event of an emergency, the necklace takes over the emergency call function by triggering an alarm on the smartphone of a previously determined security person. At the same time, a signal is transmitted to the anklet, which from that moment transmits a live GPS location to the smartphone of the security contact. This contact can inform the police and forward all relevant data. If the security person does not respond, there should be the possibility of a direct forwarding. The special feature of this system is that by pulling hard on the chain, the entire sequence is triggered, creating a very fast response capability that works without time-consuming barriers, even in the case of great panic. Carrying a smartphone is not necessary for the use of the system.
