Shot Alert sensors are unique in that they detect changes in both sound and pressure in order to determine whether or not a gunshot or explosion event has occurred.

When a gun is fired, hot and rapidly expanding gases propel the bullet out of the barrel of the gun at high speed. These gases momentarily raise the pressure in a local area. The loud sound generated is from the combination of these changes in pressure and sound. If only either sound or pressure changes are identified, the sensor does not indicate the presence of a gunshot. Furthermore, the amounts of change, total length of time for the pressure and sound events, and lag between the two events are factored in. This combination leads to an unparalleled success rate in determining that a gunshot event has taken place, while false positive responses are limited almost entirely.

Sensors connect to existing alarm panel or camera systems to alert first responders. These sensors only require low-voltage power. They are typically mounted on ceilings and are about the same size as smoke detectors.

Shot Alert boasts patented technology that detects specific combinations of auditory (sound) and pressure activity that accompany gunshots. This is the only product that utilizes the change in pressure that occurs when a firearm is discharged, which is one of the most reliably accurate measurements associated with gunshot detection. There is no need to compromise when the very best is available with Shot Alert.

Click here to let us know you are interested. One of our experienced technology partners will work with you to craft a customized detection solution based on your specific needs. They will determine the number of sensors and likely placement locations based on building size and floor-plan layout.

Shot Alert works with local integration partners to ensure high-quality installation and service in your immediate area. Each partner is thoroughly vetted and trained by Shot Alert to ensure proper placement and installation. Our partners are already experts in similar industries, such as security, fire suppression, audio/visual wiring, and other low-voltage electrical specialties.

In most installations, each sensor is able to cover approximately 50 feet by 50 feet of unobstructed room space, assuming ceiling heights of less than 24 feet. Hallways generally require a sensor every 80-100 feet, while large rooms like gymnasiums and auditoriums may require additional sensors in order to maintain effective coverage. It may be helpful to assume that a Shot Alert sensor would make sense wherever there is an existing smoke detector.

Shot alert sensors may be used outdoors in some instances. Shot Alert maintains the highest of standards of accuracy and does not recommend the use of sensors in environments where reliability is compromised.

Most Shot Alert sensors will be tied in with existing, actively monitored building systems like security and fire suppression. Upon detection of a gunshot, those partner companies receive immediate notification and are then able to contact law enforcement near instantaneously. Our units may also be leveraged to initiate the automatic door lockdown safety protocol.

Shot Alert sensors are protected by backup batteries that allow for up to two hours of continuous protection in the event the primary power source is shut off.

A wire connector allows power input and gunshot logic output between the sensor's RJ-45 connector and the alarm panel. Acceptable voltage ranges from +9V to +60v, and POE power is accepted.

Shot Alert sensors use acoustic and pressure triggers to identify gunshots. They do not track or record sounds indiscriminately. Our sensors do not record sound in a way that would make sense of normal conversations or interactions; they are specifically tuned to seek gunshots. Additionally, the sensors are part of a closed system that does not present vulnerability to hacking. Our sensors are the most secure on the market and represent an unparalleled opportunity to maintain diligent surveillance without compromising human privacy.
