A family has installed smart home devices connected through the Internet of Things (IoT).
(a) Explain the role of the smart hub in this system. [2]
(b) Describe one advantage of having a smart thermostat connected to the internet. [2]
(c) State two security risks of having smart locks and cameras connected to the internet. [2]
Answer Details
(a) The smart hub acts as the central controller that connects to and communicates with all the smart devices in the home. [1] It allows the user to control every device from a single app or interface, and enables the devices to interact with each other automatically (for example, turning lights off when the security system is armed). [1]
(b) One advantage of a smart thermostat connected to the internet is that the homeowner can control the heating remotely via a smartphone app, for example turning the heating on before arriving home from work. [1] Additionally, the thermostat can learn the household's usage patterns and automatically adjust the temperature to save energy and reduce bills. [1]
(c) Two security risks:
- If hackers gain access to the smart lock, they could unlock the door remotely, allowing physical entry to the home. [1]
- Security camera footage could be intercepted by an attacker, allowing criminals to monitor the family's movements and identify when the house is empty. [1]
