If a gun is fired, the AmberBox detectors send an alert signal through the wireless MESH network to the building gateway. The gateway automatically alerts police with a 911 call, and the AmberBox Security Operations Center is then immediately patched in to confirm the alert and guide the police or other security personnel.

Amberbox Gunshot Detection workflow

AmberBox can integrate with a range of security features and provides security personnel an easy-to-use interface to quickly respond to the situation.

The device has been tested up to 300ft and has never had a false activation or a non-activation. The device has been calibrated to 60-90 ft spacings to ensure total accuracy in its detection capabilities. As a rule of thumb, each device will cover a 5000-7500 sqft area.

Yes, AmberBox can hear through walls, but the range is affected by wall thickness. Typical range in a building, including walls, is 5000-7500 sq. ft.

Research shows that less than 1% of crimes and murders are conducted using subsonic ammunition. This is why we have focused on weaponry that is most commonly used in these type of events. However, If the weapon creates significant muzzle flash and muzzle blast, then these signatures may be strong enough to cause an activation. As part of the AmberBox package, we will provide updates to the system that will be able to better detect the presence of sub-sonic rounds.

On ceilings or walls typically at 3ft spacings away from any other electronic or lighting fixtures.

No. What is unique about AmberBox is that all the analysis is done at the detector head. The processor in the device undertakes a comparison function on the audio and infrared data input, activating only upon the unique signatures of a gunshot. The wireless communication protocol physically limits the bandwidth preventing real-time audio transmission. Furthermore, the network receives its own unique AES encryption key and data that is transmitted between devices always receives a new temporary encryption key every time data is hopped, ensuring security.

The AmberBox set up begins with a gateway being connected to the internet. This can be done via a GSM  or Ethernet connection. One gateway can coordinate up to 250 detectors.

Once the gateway is connected to the internet, the detectors  self-initialize via a IEEE 802.15.4 protocol that meshes the detectors together. This allows the sensors to quickly pass information back to the gateway where the activation can begin its external communication to police dispatch, AmberBox’s Security Operations Center and other security operatives. Therefore, no other connection (like WiFi) is required to individual detectors.

AmberBox has achieved a near-zero false alarm rate. The detection algorithms utilize machine learning to determine what is and is not a gunshot based on a massive set of data that is continually updated. Detectors receive regular over the air updates to ensure that this false positive rejection is always optimal.
