Smart Defence Spray from Plegium® is the only product of its kind on the market that automatically sends text messages with your location and makes phone calls to your emergency contacts – so that you can get help faster.

The models Smart and Smart Mini automatically pair via Bluetooth with your phone. In the Plegium app – available for iOS and Android – you can add up to 5 emergency contacts.

The Plegium app is 100% free – no monthly charge – and we bear the costs for all text messages and phone calls.


The models Smart and Combo have a powerful built-in siren, to attract attention.

The siren is louder than any other standalone personal alarm on the market.

The sound of the siren has been tuned to resonate at frequencies where the human hearing is the most sensitive.

LED Lights

The models Smart and Combo are equipped with triple LED lights, which improve aim in darkness.

The main purpose of the LEDs is to enable seeing the spray jet if it’s dark outside, and thereby improve your aim.

On top of that, the LEDs flash – 19 times per second – which has a proven disorienting effect on the attacker. Police worldwide use flashlights that flash (at ~19 times per second) to disorient people they are arresting.
