Most of the assumptions you’ve made about gunshot detection could be wrong. To those security professionals who stay on top of their homework, this is probably not true, but the ‘you’ in this context is directed to the collective security industry reader that, when looking into indoor gunshot detection products, sees terms like concussive force, percussion, or shockwave and wonders if these are important differentiators – or something the marketing department decided would get a reader’s attention. The truth is that all these terms, from an application standpoint, mean the same thing. Detractors of gunshot detection might question the validity of the technology since the perpetrator is already in action and shooting is in progress. Directing emergency personnel The purpose of gunshot detection is to alert with absolute certainty and as soon as possible that there is a shooting in progress, and very importantly, to identify the location of the incident. The purpose of gunshot detection is to alert with absolute certainty and as soon as possible With this information, we can guide victims away from the shooter while also directing emergency personnel to the perpetrator’s location so they can mitigate the threat. If your loved one found themselves in a work or school shooting, which would you prefer – that they hide until law enforcement arrives, or that they know a safe path for immediate evacuation? As a security operator, would you prefer to manually search camera feeds to find the shooter, or have gunshot detection instantly cue cameras to the incident location? Gunshot detection technologies When you see the value gunshot detection has to offer, the next step is gaining a deeper understanding of the technology and sifting through marketing claims to find the system that works for your application. Before jumping into the circuit boards and algorithms of modern indoor gunshot detection sensors, it helps to go back in time and learn about the genesis of gunshot detection technologies. Many sources generalise gunshot detection into two classifications: military or civilian/law enforcement application. Gunshot detection’s history tracks back to systems built in the 1990s for military applications that detected and reported on sniper fire from high calibre weapons. These systems were then made available for civilian applications in the form of city-wide applications that triangulate signals to locate gunfire in urban areas. Existing outdoor technology This feeds the collective understanding that all gunshot detection systems operate in one simplistic way Although these systems differ in how they detect, locate, and report gunfire, at their core is a reliance on acoustics (and therefore microphones) as their single mode of detection. Because these systems were essentially first to market, they are the most publicised and reported on. This feeds the collective understanding that all gunshot detection systems operate in one simplistic way; they ‘listen’ for the sound of gunshots, triangulate a location, and then produce some type of alert. Detecting a gunshot outdoors is different than detecting one indoors. Early attempts by indoor gunshot detection pioneers to use the existing outdoor technology didn’t work very well. There are several reasons for this, but they can be summarised as follows: The acoustic pattern of a gunshot indoors is different than one that is produced outdoors. Walls, furniture, and general building layout will create echoes and reverberations that combine to create a signal that is difficult to interpretate. Some outdoor systems were reliant on the shockwave of supersonic rounds outdoors. In the indoor environment, the acoustic properties of that shockwave can break down quickly, rendering the result degraded and therefore unusable as a reliable indicator of gunfire. Systems reliant upon triangulation, like the ones used in city applications, also do not work indoors because those echoes and reflections in the acoustic environment interfere with both detection and location accuracy. Indoor gunshot detection This compression continues as the bullet moves forward through the air Indoor gunshot detection requires a different approach. But before diving into the deep end of the technical pool, a few words about what happens when a gun is fired. We are all familiar with the bullet flying out of the gun part, but what else happens? When the bullet leaves the muzzle (end) of the gun, air molecules around the bullet get rapidly compressed. Just like a guitar string that has just been plucked, rapid compression or vibration moves the air molecules around it. This compression continues as the bullet moves forward through the air, but the initial, violent change is what we first capture. The gasses that are part of the gun powder burned to propel the bullet out of the gun are also released. This causes a ‘flash’ which can been recorded as part of the visible and infrared (IR) spectrum. Indoor gunshot detection requires a different approach Sound pressure sensor The talk of 'rapid vibrating or compression of air molecules’ is where confusion can begin. Why? Because this same property can be measured in different ways. One way is acoustical – a microphone recording the ‘bang’. Another way is through pressure. But wait a minute – if we remember our high school physics, a sound wave is the same as a pressure wave! Simply stated, a microphone is a pressure sensor - usually tuned to capture very small changes - and a sound pressure sensor is just a clunky microphone. As humans, we forget that sound – like the loud bang of a firearm – is just our way of describing a very distinct change in the vibrations of air molecules around us. Air pressure sensors Gunshot detection devices use sensors to detect a change in the compression of air molecules Gunshot detection devices use sensors to detect a change in the compression of air molecules. Manufacturers can say that they use different types of sensors – microphones, air pressure sensors, concussive force sensors, shockwave sensors, etc. – but these devices are all measuring the same thing. The primary difference between different sensors is how sensitive to disruption they are, which is usually a function of cost, and what frequency or range of disruption they are designed to look for. Some manufacturers claim to capture the ‘shockwave’ of a bullet. Shockwave is a rather loose term, but the manufacturer is usually referring to a special pressure wave in the air that is created when an object travels faster than the speed of the sound. An object passing through the sound barrier will make a loud noise – or large, fast pressure change – but again, the sensor is simply capturing a change in the compression of air molecules. Serving particular market At first, the idea of using a bullet’s speed – and therefore shockwave - as an inexpensive mechanism for capturing and verifying that a gunshot has occurred may seem interesting. But be careful of products that promote shockwave as their principal factor of gunshot detection. Many types of bullets – a 45 calibre pistol for example – do not create a shockwave when fired, meaning these types of gunshots fired in your building will be excluded from detection. Manufacturers all take different approaches to serving a particular market. In the world of security, one would hope that all products deliver exactly as advertised. Unfortunately, a sensor that is calibrated to one range of sound or pressure can inadvertently register other, unwanted sounds. Different building configurations A nail gun or balloon popping will trip a sensor calibrated to listen for the frequency A nail gun or balloon popping will trip a sensor calibrated to listen for the frequency – or vibrational – range of most gunshots. Sensors can be pre-programmed with a library of gunshot-like sounds, but this requires the sensor to analyse the signal it just captured, creating a delay in alert times. A study done by Florida Atlantic University’s College of Engineering and Computer Science recently concluded that ‘most gunshot detection systems cannot tell the difference between a gunshot and a plastic bag popping’ – and this points to why consumers believe that gunshot detection systems are unreliable. Also, as we learned above, different building configurations will create different signal characteristics. Is there a library of gunshots signals for all possible building or room configurations? Single sensor approach As a way to reduce costs, some manufacturers offer a single measurement sensor for both indoor and outdoor applications, but this approach requires extensive calibration for two different environments, meaning that accuracy inevitability suffers. As a way to reduce costs, some manufacturers offer a single measurement sensor Define your expectations accordingly because the single sensor approach is limited. The level of accuracy will be low, and you will experience false alerts, creating a need for an additional layer of verification that further delays notification. In the physics lesson above, we mentioned that there was a second characteristic of a gunshot – the release of light – or more accurately, heat – from the infrared (IR) spectrum. To avoid the problem of concussive force/shockwave/microphone sensors capturing signals that are not gunshots, a second sensor dedicated to measuring the IR signal emitted by a bullet leaving a gun is added. Generate false alerts Just like online banking services enforce two-factor authentication to ensure authenticity, gunshot detectors can use two sensors measuring the two different characteristics of a gunshot to deliver the highest level of accuracy. And since the speed of light and the speed of sound are different, programming can be employed to further validate that the signal received was truly a gunshot and not a similar-sounding non-ballistic event, like a nail gun. From an accuracy standpoint, single measurement sensors perform worse than a dual-sensor in all cases and are significantly more likely to generate false alerts. The only benefit of a single-sensor shot detection system is that they may be cheaper to purchase in terms of upfront costs. But those savings will quickly be erased by the cost of avoidable business disruptions due to a higher false alert rate. Normal hospital services Schools are probably the hardest to estimate as intangible costs like staff/student wellbeing In manufacturing, warehousing, or transportation environment your accounting department can easily calculate how much a one-hour shutdown of work will cost the organisation if a false alert causes an interruption in operations. In industries like healthcare, calculating the cost of a false alert is a little more complicated, but one study determined that cancelling normal hospital services for just one day can cost approximately $978,418.00. Schools are probably the hardest to estimate as intangible costs like staff/student wellbeing and law enforcement-related activities do not lend themselves to a straightforward financial calculus. Single measurement sensors However, when investigating indoor gunshot detection systems, the following top five questions should be asked of each vendor you contact: Does the system use Single Factor or Dual Factor sensor verification to reduce false alerts? The definition of Dual Factor, in this case, is that both factors are required to produce a gunshot alert. Remember that merely adding more single measurement sensors to a product will not reduce false alerts. Does the manufacturer have an independent, third-party verification of their product? If so, what were the testing parameters? Look for gunshots occluded (facing away) from the sensor, types of noises tested including firearms and false alert tools used, sensor distance from the gunshot, and the validity of the testing agency as a trusted, impartial operation. Real-world testing is also extremely valuable, meaning in a customer’s installed environment, outside of the gun range. If the single factor sensor is advertised to work both indoors and outdoors, how does the device technology compensate for these two different environments? Does the manufacturer’s solution require a human to validate that the signal received was a gunshot? Systems that require human verification will considerably slow down the speed at which Law Enforcement is contacted and, because of normal human behaviors during periods of stress, can also lead to inaccurate information being communicated to first responders. Is the manufacturer an expert in gunshot detection or did they just add a microphone to a product and bundle it with other types of sensors like smoke detection, aggression, vaping, glass breaking, etc.? These all-in-one sensors are currently common as manufacturers attempt to test the market’s appetite for gunshot detection. False gunshot alert There are currently no regulatory bodies monitoring gunshot detection manufacturers and their claims Gunshot detection does not have to be complicated, but when an emerging technology begins to gain traction in the marketplace, it is important to follow the science and keep learning. There are currently no regulatory bodies monitoring gunshot detection manufacturers and their claims, so doing your due diligence is key with this technology. Talk to your business leaders about the impact a false gunshot alert could have on the organisation from a risk standpoint. Seek to understand the underlying technology of any shot detection system you are considering and look for two factors of gunshot authentication. Hopefully, this technology primer on gunshot detection helps integrators and end-users understand the underlying technology so they can find the most effective solution for their facilities.

The benefits of some physical security systems have an obvious return on investment, such as surveillance cameras trained on retail cashiers and access systems that keep unauthorised persons from entering protected areas. There are others that may only show a return once a negative event has occurred, and some may argue that gunshot detection falls into this category, however there are many reasons to see the value in this technology. Below are a few reasons why you should look at gunshot detection and some best practices for evaluating this type of technology.    Reduced casualties = reduced costs Most of gunshot detection’s value will be measured on the system’s ability to reduce response time to a shooting incident. Statistics have shown that an average of one death occurs every 5-15 seconds during an active shooter incident. One question to ask gunshot detection manufacturers is how quickly their system alerts. Applying these statistics against alerting speed can help calculate a potential reduction in casualties to employees.Mitigating casualties can also reduce subsequent benefit costs for those psychologically traumatised by the incident Mitigating casualties can also reduce subsequent benefit costs including paid sick leave, death benefits, and mental health care for those psychologically traumatised by the incident. To put this into real-world context, a major retail brand experienced a workplace shooting that tragically resulted in loss of lives and multiple casualties. The corporation spent more than $40M in costs associated with the shooting. It was after this incident that the company decided to install gunshot detection, because although they had looked at it previously, they finally made the connection to the return on investment: Reduced response time will decrease (and hopefully eliminate) casualties, which will save lives and millions of dollars if a future incident were to occur at one of their sites. Meeting OSHA requirements OSHA’s General Duty Clause states that employers must provide a workplace free of “recognised hazards” that are likely to cause death or serious injury. Courts have interpreted this to mean that employers have a legal obligation to abate the active shooter hazard when there is a feasible method available to do so.   Mark Terry, Director of Global Enterprise Security for Rackspace in San Antonio, sees gunshot detection as a life safety necessity that also fulfils the corporation’s Duty of Care. He told me that adding gunshot detection is not only a game changer for active shooter response, it fulfils their Duty of Care and brings peace of mind that his company has done everything they can to protect their people. Lawsuits charging security negligence have become commonplace after shootings Reduce litigation risk with gunshot detection – but choose wisely Lawsuits charging security negligence have become commonplace after shootings, naming a “lack of gunshot detection devices” as a source of culpability, such as the $800M lawsuit victims brought against MGM after the Route 91 concert shooting in October 2017. What is important to realise, however, is that not all gunshot detection systems are created equal, so there are a number of performance characteristics to consider. For example, acoustic-only systems have a higher likelihood of false alerting to loud noises, especially indoors, as do those that search a library of gunshot audio files before reporting shots.Dual mode systems that require both acoustic and infrared detection in order to report are far more accurate Dual mode systems that require both acoustic and infrared detection in order to report are far more accurate. Tedd Steele, Senior Network Architect at Charleston International Airport, told Airport Improvement Magazine that the system they installed “can determine gunshots with a high degree of accuracy thanks to the dual mode sensors. It knows the difference between loud bangs and a gunshot.” When looking at wireless gunshot detection systems, end users should ask about sensor uptime, self-testing features, battery life and encrypted communications.   Regulations and standards Currently, there are no standards or regulations to follow in order to market a technology as gunshot detection. A video camera is typical in that you can expect that the product will capture video. There are different feature sets like facial recognition and analytics that set different systems apart on the backend, but first, cameras must capture a moving image. When you apply this same analogy to gunshot detection, the waters are a bit muddier because the science of isolating gunshots while also filtering out false alerts is much more complex than simply detecting and reporting a loud bang.The NFPA has also issued guidelines for the use of gunshot detection Many manufacturers of aggression detection systems now claim ‘gunshot detection’ as a feature set, and there are smoke detectors and cameras now marketing this claim, but these devices are not on the same level playing field as genuine gunshot detection systems. In the absence of regulations and standards, consumers should look to authorities that have evaluated systems such as the U.S. Department of Homeland Security and the Centre for the Protection of Critical Infrastructure in the U.K., The NFPA has also issued guidelines for the use of gunshot detection as a part of their principal role in creating life safety codes for buildings.   Testing and References If you place a number of gunshot detection systems side by side in a shooting range, they all will likely report a shot, but this is not a reasonable test because a range is a controlled environment. What happens in a real world environment? Does the system need to be calibrated to its environment? What happens in the presence of fire alarms and strobes going off in a live incident? Seeing a system respond to live fire is important in the evaluation process, but it is not the only marker of overall system capability.   Consumers will want to ask manufactures questions like how many systems have been deployed in customer environments and for how long, and let their customers tell you their detection and false alert rates have been. Enterprise consumers will want to look closely at network and cybersecurity features and look closely for any potential security risks. Also ask for references from customers in your industry so you can see how and where they are using gunshot detection to meet challenges that might be unique to your type of workplace, school, or public venue. Seeing a system respond to live fire is important in the evaluation process Overall, it is extremely important for organisations to be able to declare that they have done everything in their power to properly prepare for and respond to active shooters. Combining an effective gunshot detection system with video, access control and mass notification will not only improve your ability to effectively respond to a shooting incident, it raises your security posture and confidence that you have done everything you can to protect your people from modern day threats. It also puts these security systems to better use by delivering real-time, additional situational awareness during a shooting incident. And this will be especially true when you have done your due diligence before selecting a gunshot detection system.

Gunshot detection today is part of more physical security systems than ever before, and many manufacturers are developing interfaces to the latest gunshot detection technologies. Genetec has integrated ShotSpotter gunshot detection technology into its unified IP security platform, Security Center. Thanks to this integration, police departments and security professionals will be able to receive more actionable information, gain rapid access and detailed location insights when a gunshot situation occurs.   Cloud-based analysis software ShotSpotter uses wide-area acoustic surveillance that automatically gets activated when gunfire occurs, providing comprehensive outdoor coverage on campuses and in complex urban geographies. ShotSpotter sensors and cloud-based analysis software triangulate and pinpoint the precise location of each round fired within seconds, the number of shots fired and provide an immediate gunfire alert with an audio clip. Detailed incident data is immediately sent to SST’s Incident Review Center (IRC), a secure data processing and alert validation facility, where acoustics experts analyse the data and qualify the incident in real-time 24/7. Once validated, an alert is sent directly into Genetec’s Security Center, all in under a minute. Once the alarm is triggered within Security Center upon gunshot detection, operators can quickly access video and other related data surrounding the location of a gunshot alert, and immediately visualise it on Security Center maps, leveraging the dynamic visualisation capabilities of the Security Center Plan Manager. Genetec has integrated ShotSpotter gunshot detection technology into its unified IP security platform Gunshot identification software Stanley Security has announced a partnership with Shooter Detection Systems LLC (SDS), gunshot detection solutions provider. As an authorised dealer, STANLEY Security is now certified to sell, install and service SDS products and services. SDS’s Guardian Indoor Active Shooter Detection System combines acoustic gunshot identification software with infrared gunfire flash detection for a fully automated gunshot detection and alerting solution. The Guardian System immediately detects gunshots and simultaneously alerts building occupants The Guardian System immediately detects gunshots and simultaneously alerts building occupants and first responders within one second and with zero false alerts. Johnson Controls has announced that its exacqVision video management system now integrates with Databuoy Corp.’s ShotPoint acoustic gunshot detection and localisation system to speed response time and heighten the decision-making process for local responders during active shooter situations. Integrated security systems Johnson Controls has also released the Detect360 Active Shooter Response (ASR) system, combining reliable gunshot detection with notification technology to provide immediate warning when a gunshot is fired within a building. By providing early notification and precise location of the shooter, the ASR system gives occupants time to find safety and allows police and security personnel to mitigate the threat up to 60 percent faster. Detect360 ASR gives first responders information as it develops at the scene, including shot location, number of shots, location of the shooter in near real-time and the ability to remotely monitor the situation through integrated security systems. It also collects forensic information that can later be used by law enforcement. The system supports multiple integration options, including video feeds from existing CCTV and intrusion systems, mass notification systems, access control systems and panic button/manual initiation systems. Public safety access points Listed as one of the most important new technologies debuted at CES 2019 by the Wall Street Journal and NBC News, Safe Zone also showcased its Safe Zone Gunfire Detector (GFD) at ISC West 2019. Priced at $149 per unit, the Safe Zone Gunfire Detector combines infrared and sound detection technologies with immediate cloud-based data analysis that can analyse more than 3,000 data points of each loud noise that exceeds ambient levels by a certain threshold. Utilising the data from multiple detectors simultaneously, the system determines the location of shots fired, the number of shots, and the type and calibre of gun being used. Within 10 seconds of the trigger pull, an alert is sent to Public Safety Access Points in the appropriate dispatch center, giving local 911 dispatchers all critical information on their computers.
