Principle of Proportionality
Gradual pre-alarm: 118 dB immediately, then increases to 133 dB after an adjustable delay of 10, 20, or 30 seconds.
This principle of gradation combines immediacy with proportionality in the response.
Alarm cycle: 1 to 3 minutes, resettable.

Gyroscopic tamper protection
Thanks to its built-in gyroscope-based self-protection system, any tampering, significant vibration, or unauthorized attempt to move the device may trigger the automatic activation of the cannon for a programmable duration.
This protection can remain active even when the system is disarmed, providing continuous security against tampering attempts.
Only a technician key can disable this feature.
Note: Do not activate this self-protection feature when the device is placed on the ground or when securing goods in a vehicle.
CS Tear Gas Dispenser Option:
For the most determined individuals, we also offer a 100-ml CS tear gas dispenser with a coverage area of 450 m³ that can be mounted separately or built into our sound cannons.
We recommend CS gas in a formulation intended for civilian use (available over the counter at gun shops).
-
Category D firearm.
-
Acquisition and unrestricted possession (adults).
-
Carrying and transporting prohibited; use restricted to private property.
Three triggering methods:
1 - Triggering manual remote activation via a mobile app.
2 - Triggered by seismic detection (self-protection of the sound cannon).
3 - Triggering Automatic following a confirmed intrusion + warning siren + safety delay.
Unlike pepper spray, CS gas disperses very easily and leaves no lingering traces.
CS gas is heavier than air.
It doesn't matter how high the ceiling is. Microdroplets linger at head height and gradually fall.
