Report summary

This report provides Transforma Insights’ view on the ‘Public Alarms and Monitors’ IoT market. This segment primarily focuses on gunshot detectors, automated emergency responses, and public warning systems.

Gun violence is a major concern in many countries. Homicides and mass shootings are rising and many of them are not being reported to the authorities. IoT-based solutions are being implemented to combat this situation and they ensure that gunshot incidents are accurately reported to the concerned authorities. Authorities are also using IoT solutions to alert citizens about impending disasters, such as earthquakes. While most gunshot detection solutions work using a Wi-Fi Mesh network, public alarms frequently make use of LPWA and cellular technologies to alert citizens about potential upcoming hazards.

The report provides a detailed definition of the sector, an analysis of market development, and profiles of the key vendors in the space. It also provides a summary of the current status of adoption and Transforma Insights’ ten-year forecasts for the market. The forecasts include analysis of the number of IoT connections by geography, the technologies used and revenue.

A full set of forecast data, including country-level forecasts, sector breakdowns and public/private network splits, is available through the IoT Forecast tool.

Key market developments in Public Alarms & Monitors market

The report examines key factors that are influencing the development of the Public Alarms & Monitors market, including:

Primary drivers for Public Alarms & Monitors

The report argues that gun violence is the principal source of demand for public monitoring systems, since the number of gun-related violence is quite high, and the number of reported incidents is astonishingly low. It explains how IoT-based solutions are implemented to combat this situation, their working mechanism, and how they have succeeded in making a difference.

Major challenges faced by gunshot detectors

The report then discusses the challenges that are faced by gunshot detectors (including the cost of deployment of these solutions) and provides real-life examples of how governments and other agencies are trying to deal with such challenges with innovative solutions.

Deployment of gunshot detectors

The report also charts some of the major deployments of gunshot detectors from companies like SoundThinking and how they have positively impacted the number of homicides, gunshot incidents, and other violent crimes. It lists 20 major cities across the US (such as Miami and Las Vegas) in a tabular format and has explained how the deployment of gunshot detectors has reduced the number of violent crimes in these places. It also mentions some crucial real-life examples of relevant IoT deployments in this application (one of them being the Memphis Police Department investing USD650,000 to deploy gunshot detection technology to assist its officers).

Other use cases of public alarms and monitors

The report also discusses how IoT solutions (such as a combination of digital signages and public alert systems) are used to alert the public about impending natural disasters and mitigating their impacts. Apart from digital signages and public alert systems, the scope of smartphones in this context has been analysed in detail as well. It touches upon the distinct advantages of cell broadcasting solutions over public alarms and provided examples from real-life deployments.
