Building safer cities with advanced public safety technology

What is public safety technology?

Public safety technology refers to the tools and systems used by law enforcement, emergency services, border control and other agencies to protect communities from disruptive or harmful events. It integrates advanced devices and software to perform tasks more quickly and accurately, as well as reducing reliance on manual processes.

Agencies can deploy public safety technology in various ways, such as observing transportation networks or managing crowd flow. A common example is AI camera systems, which can analyze live footage, detect unusual or suspicious activity and alert authorities in real time. This helps the authorities maintain order and respond proactively to potential threats.

Why is public safety technology important?

Public safety technology plays a critical role in creating safer environments, particularly in urban areas where the density of people and activity can increase the likelihood of incidents. Advanced security systems equipped with smart technology help agencies respond more quickly to crime, plan for emergencies such as natural disasters and identify potential hazards before they escalate.

While the Council on Criminal Justice reports that overall crime has declined in the United States since the pandemic, more than 60% of cities surveyed have experienced increased homicide rates since 2020. Rising violent crime is a key driver of public concern, highlighting the need for effective safety measures.

By adopting public safety technology, agencies can prevent and mitigate incidents while improving public trust. Enhanced security infrastructure demonstrates a commitment to protecting communities and maintaining public confidence in law enforcement.

10 examples of public safety technology

Public safety technology includes devices, software and protocols designed to improve security in areas prone to incidents. Some examples include: 

1. Video security systems

Video cameras are among the most widely adopted tools for public safety. Networks of cameras integrated with cloud platforms offer comprehensive observation of public spaces. 

Higher-resolution footage improves the identification and analysis of suspicious behavior. A U.S. National Institute of Justice meta-analysis of 76 studies found video security systems reduced overall crime by 14%, with property and vehicle crimes decreasing by 16% each.

2. Smart pedestrian crossings

Public safety technology includes smart pedestrian crossings that use IoT-enabled motion sensors and adaptive lighting to improve visibility and protect pedestrians. These systems can detect when someone is approaching an intersection and alert drivers through flashing lights or other signaling methods.

By enhancing awareness at crosswalks, particularly in low-light conditions, smart pedestrian crossings help reduce accidents and improve overall traffic safety. Additionally, automated lighting systems can conserve energy by activating only when needed, combining safety with sustainability.

3. Drones

Drones provide emergency responders with rapid situational awareness and improved resource allocation. Their aerial views and 360-degree cameras are invaluable during public safety events.

4. Augmented and virtual reality

Public safety technology also includes augmented reality (AR) and virtual reality (VR) platforms, which provide emergency responders and public safety officials with immersive training experiences. These systems simulate realistic public safety scenarios, such as natural disasters, accidents or active shooter events, to allow personnel to practice response protocols safely and effectively.

By replicating complex or high-risk situations in a controlled environment, AR and VR technologies help improve decision-making and preparedness for real-world incidents.

5. Data analytics platforms

Public safety technology increasingly relies on advanced data analytics platforms to help agencies make smarter, evidence-based decisions. These platforms process vast amounts of data from multiple sources, such as video feeds, sensors, crime reports and social media, to identify patterns and potential risks.

6. Public real-time response systems

Public safety technology includes real-time response systems that alert both authorities and the public to emergencies as they occur. These systems can automatically trigger actions based on data from connected devices, such as cameras and sensors, to help emergency services respond more quickly and efficiently.

7. Geofencing

Geofencing uses GPS technology to create virtual boundaries around specific areas, sending alerts or messages when individuals or vehicles enter or leave the designated zone. This capability helps authorities manage public spaces, regulate traffic and enforce safety protocols more efficiently.

8. Smart lighting

Smart lighting systems use sensors to detect pedestrians or vehicles, automatically adjusting brightness to improve visibility and safety. By illuminating streets and isolated areas only when needed, these systems help deter crime and reduce accidents while conserving energy and lowering public electricity costs.

9. Environmental sensors 

Environmental sensors monitor air quality, water conditions, weather and other environmental factors in real time and provide vital data to public authorities and communities. These devices can alert officials to potential health hazards, flooding risks or pollution events to enable faster, more informed responses.

10. Gunshot detection systems

Gunshot detection systems (GDS) instantly identify the sound and location of firearm discharges and alert authorities to respond quickly to active incidents. Many systems can also notify nearby residents or workers and guide them to safety during potential threats.

Research from the U.S. National Institute of Justice in 2024 found that cities using GDS experienced a twofold increase in shooting alerts. This significantly reduces the time between incident detection and officer deployment.

How can people benefit from public safety technologies?

Public safety technology offers numerous benefits for communities by providing more precise data, comprehensive oversight and tools that enable agencies to respond proactively to potential threats. By integrating smart systems, authorities can develop more effective strategies to protect the public and maintain safety in urban and high-risk areas.

Key benefits of public safety technologies include:

• Reduced crime: Video security systems and AI-assisted analytics allow law enforcement to detect suspicious activity faster, respond more efficiently and identify suspects with greater accuracy.
• Faster emergency responses: Drones, gunshot detection systems and other real-time tools help emergency responders act quickly and make informed decisions during critical incidents, such as active shooter events or terrorist attacks.
