All our demonstrations will take place in a large marquee on Millennium Square.

Given the critical importance of security in cities, innovative advances in wireless communications system are increasingly improving the safety of city inhabitants. New services such as audio and video monitoring of public areas and automated municipality rule infraction detection, allow a quicker response to threats and anomalies and all in order to prevent reoccurrence. The University of Bristol has deployed a smart city safety case study, as a proof of concept, to identify suspicious activities in the city. The basic components of this case study are listed below and they are connected together to the Internet through a WiFi Interface.

• Bike rider helmet
• Raspberry PI
• 360 degree camera and audio

Figure 1 shows a high level architecture of the smart city safety use case. The bike rider carries his helmet, to which the Raspberry PI is attached with a 360-degree camera. The bike rider's journey is captured with video and audio and sent via WiFi to the Mobile Edge Computing (MEC) or Cloud, to be processed. Once the audio and video has been processed and any suspicious activity has been detected, a notification is generated and sent to the different security agents.

Many of today’s municipalities are becoming test beds for the smart city experimentation, where technological capabilities are addressing daily needs ranging from parking to water treatment and city security. The University of Bristol is working to provide, through the 5GinFIRE platform, a smart city safety use case which has been deployed according to the architecture shown in Figure 2.
