Gunshot Detection Integration with Milestone XProtect


App-Techs' BTX (Bridge to XProtect) integrates Active Guardian gunshot detection sensors with Milestone XProtect.


Active Guardian's award-winning gunshot detection technology uniquely identifies high-frequency concussive shockwaves distinct to gunfire. Unlike other solutions that rely on microphones or infrared sensors, Active Guardian devices are accurate and virtually impervious to background and environmental noise, including vehicle backfires, door and trunk slams, shouting, power equipment, and falling objects striking hard surfaces.


With BTX, Active Guardian users can monitor for gunshot alarms within the XProtect Smart Client. A detection generates an immediate alarm in XProtect, which allows you view detections in real-time, initiate camera views, Smart Wall commands, lockdown protocols, audio announcements, text / email / mobile notifications, access control commands, I/O triggers, along with a range of other security responses.



Active Guardian - Milestone XProtect integration features:


  • Associate Active Guardian sensors(s) with any number of XProtect cameras or devices.
  • Generate XProtect gunshot alarms with video bookmarks.
  • Activate PTZ presets based on the direction of detection (8-sensor devices).
  • Fire Smart Client matrix views.
  • Trigger Milestone user-defined events and rules.
  • Monitor offline status alarms for deployed Sentinel devices.
  • Manage all Sentinel devices from a single user-interface.



Integrate any number of Active Guardian devices with a single instance of BTX. Monitor sensor status and send notifications when a sensor is offline.

How It Works


BTX works by listening for, receiving, and transforming Active Guardian gunshot detection alarms into Milestone-ready alarm records.


Any number of Active Guardian sensors can be pointed to and managed by BTX. BTX is continually monitoring the online status of each device and can be configured to generate an XProtect alarm if a device is unresponsive.


When an Active Guardian device detects a gunhshot, BTX receives the alarm, identifies the device of origin, associates the alarm with user-designated XProtect cameras and/or devices, and generates an XProtect alarm record with video bookmarks.


BTX simultaneously activates matrix views, user-defined events, and PTZ presets without the need to create device-specific XProtect rules.


Result: Within a second, your video and security network spring into action to evaluate the potential threat.
