A smart device is an electrical item that can be connected to the internet – most commonly via wifi – and remotely controlled. They include ‘hi-tech’ devices such as smart speakers, fitness trackers and security cameras, as well as standard household items such as kettles and fridges.
They use various sensors to collect data about their environment – such as temperature, light levels or motion – and then use this to automate tasks for us. Often, they can also alert us to changes or anomalies with the environment or system. The devices are usually based on a hub that allows them to communicate with other smart devices or systems, using various wireless protocols such as Bluetooth, Zigbee, Wi-Fi, near field communication (NFC), cellular networks, and others.
The technology can be used to make everyday tasks easier, and improve quality of life with a range of features such as voice assistants that allow you to control the device with your voice. But there are a number of issues to be aware of when it comes to smart devices, including privacy and security.
It’s important to keep your smart devices up to date, as manufacturers release software updates that can fix bugs or vulnerabilities in the products – which could put your privacy or data at risk. You can do this by following the guidance provided by the manufacturer – this may be a printed sheet or ‘getting started’ guide that came with the device, within the app itself, or on the manufacturers website.
