Not only does the Internet of Things make it easier for us to complete daily tasks, it also greatly assists in ensuring the safety of people in ways that are beyond the capability of humans. Using smart technology, people are able to quickly and efficiently address safety issues at a rate that could not be previously achieved with just manpower alone.

1. Building Safety and Security

Cameras have been used for years for safety purposes by public buildings and private business locations. Before, a camera would simply feed images into a monitor and record all that passes within its field of vision. Now, with the birth and implementation of the smart camera, cameras can monitor and recognise people and things that enter, move through, and exit buildings. Instead of having a security guard monitor multiple camera feeds at once and somehow miraculously be able to detect suspicious activity on one of them, smart cameras can do the monitoring for them. If something unusual is detected, the security guard can be notified and the related video can be shared and assessed, and the potential threat can be addressed quickly.

2. Airport Security

With the large number of people coming and going through airports every day, security is of utmost importance and should be a main priority at airports. In this day and age, humans alone are not enough to make sure airports are safe for passengers and visitors. Smart technology has already been implemented to help with security in airports, one example being the smart camera. In the future, smart cameras will be able to detect “safe” faces, which are faces of people who have already passed screening or have taken affirmative steps to be included in a “safe” facial recognition file. This includes faces of employees such as pilots and flight crew members, among others. Smart cameras will be able to identify these people, providing them access into the terminals, and reducing the number of people screened by security agents.

3. Safety in Cities

Smart technology is also beginning to see an increased use in cities for safety purposes. Computer vision will be used to monitor traffic, where strategically-placed cameras send large amounts of data about traffic to enable easier making of real-time decisions to maintain optimal traffic flow. When autonomous vehicles are connected to the traffic system, alerts, routing information, and instructions between cars and traffic systems will be generated. Both the cars and the traffic control infrastructure will handle this data to ensure that traffic moves as smoothly as possible.

The uses of smart technology in cities isn’t limited to just traffic control, however. In addition to smart cameras, devices such as microphones and sensors are implemented to continuously monitor streets in case any problems or potential threats arise. Microphones can be used to detect unusual noise such as the sound of a car accident or people shouting, and having it connected to a smart system means the audio can be sent to the authorities with relevant data about the source and the location of the audio. Smart cameras will be able to read license plates, which can help authorities in detecting the whereabouts of specific people with ease by tracking car plate numbers.

As much as it is said that IoT can be dangerous, it’s undeniable that it has its benefits in safety and security. While certain precautions must still be taken to ensure nothing goes wrong, IoT helps us in many ways to make it easier for us to stay safe in this world.
