Safety and Security

Growing up in the 80’s I remember being able to ride around town without any fear. We were taught stranger danger but we also had a neighborhood watch. The neighborhood watch was implemented by communities to not only watch over the exploring children; but to keep an eye out for any unusual and suspicious activity. This then involved someone making the decision to call the authorities.

Now the world has grown and the neighborhood watch theory is evolving to incorporate technological advances. For example, local authorities are now using Facebook sites to seek information including tracking down missing people. This advance is now expanding to use Internet of Things (IoT), which are physical systems that are already in place to create a Safe City.

A Safe City uses multiple elements to assist already established authorities and emergency services to alert and dispatch the appropriate teams. The below flow chart offers a snapshot on how this works.

For example, a gunshot is heard in the heart of a city. The closest Internet of Things (IoT) notices the anomaly and a real time alert is sent to the closest decision centre. Probably the local police, who then send out first responders. This will mean that the personnel can start performing their jobs faster. Because they did not need to wait until someone called them.

The concept of bringing together Internet of Things (IoT) into a Safe City has been already started. Nanjing applied a Safe City during the 2013 Asian Youth Games, where they used drones in the vicinity to watch over the city and respond to any event.

Sacramento have already started bringing together their existing Internet of Things (IoT) to better respond to crime.

An article in The Australian last year highlighted that the use of technology alone will not make a community a Safe City, and this correct. We need ensure that the technology is used as an assistance to those working in the emergency services fields to better respond to unsafe events.
