Remote controls are used to operate electronic devices, such as televisions and DVD players, using wireless links instead of physical wires. They usually feature a numeric keypad and directional buttons, used to adjust common settings like volume, channel, and track number. Power buttons are also included in most models. They are usually powered by AA or AAA alkaline batteries. Remote controls may be dedicated to a specific device, or designed to work with all devices.
Radio remote controls connect to the device using radio waves with frequencies of about 400 MHz. They are commonly used with garage doors, alarms, and remote-controlled toys. They usually come with lock codes to prevent them from opening other doors or vehicles.
Infrared remote controls
Infrared remote controls use pulses of infrared light to send commands to the device. They are used with consumer electronics, such as TVs, VCRs, radios, and home entertainment systems. Most models come with built-in codes to identify the make and model of the device with which they are used.
Frequency: When choosing radio remote controls, make sure they operate at a low frequency to reduce interruption. Look for one with consistent signal strength and range so that you can use them from across large rooms.
Security: Choose a remote control with a dynamic code instead of a static one to protect them from getting hacked. This is especially important for car and garage remotes, since hackers can obtain your code using code grabbers.
