When it comes to public safety, how much oversight and surveillance is enough, and how much is too much? Where do you draw the line between safety and invasion of privacy? These are questions policymakers and law enforcement officials struggle with every day. There are usually no easy answers.

A good starting point is to look at the role technologies like video surveillance can play in public safety, and what applications such technologies are most effective for particularly for providing an adequate degree of situational awareness.

Video surveillance is very prevalent in the U.K. where the typical person is recorded 20 times a day.  It is gaining ground in the U.S. where post-9/11 has made people feel less safe and created a desire to have their “guardians” always watching in public spaces. However, omnipresence for the sake of security has a price. It does invade personal privacy. 

This concern has only grown as sophisticated video and network technologies like 4G LTE— which is increasingly the technology of choice for massively deployed machine-to-machine (M2M) monitoring solutions— enable video can be not just automatically captured but also quickly analyzed to, for example, use facial recognition to ID a person or check a license plate against records in a database.
