Wireless remote controls are devices that allow users to operate electronic equipment from a distance without the need for physical connections. They typically use radio frequency (RF) or infrared (IR) signals to communicate with devices like televisions, DVD players, and sound systems. This convenience enables users to change channels, adjust volume, or play media without getting up. These remotes often feature buttons for various functions and may include additional features like programmable settings or backlighting. Many modern remote controls can also be used with smart home devices, allowing users to control lights, thermostats, and security systems from one device.
