A waterproof remote control can be used in a pool, shower, or other environment where the controller runs a risk of getting wet. Many of these remotes allow users to control various electronic devices, such as audiovisual equipment or spa controls. Others have options, such as flotation capabilities, tethers, or rubber hand-grips. These remotes may use either radio frequency (RF) or infrared (IR) signals, or a combination of both, to control the electronics.
Many people purchase a waterproof remote control to use in areas where the remote is likely to be splashed or even submerged in water or other liquids. Many of these remotes are used out of doors in pool or spa areas. They may also be useful in bathrooms or kitchens.
The most common type of waterproof remote control works with a variety of electronics, much like a standard universal remote control. Waterproof remotes often allow users to manipulate audiovisual equipment, such as televisions, DVD players, and speaker systems. Some may also be programmed to work with pool or spa controls.
A common feature in waterproof remotes is the ability to float. These remotes are sealed with air pockets that keep them afloat in liquids. For example, some individuals find floating remotes to be useful for easy retrieval if the controller falls into a pool or bathtub. Also, many users enjoy the ability to leave the remote floating in the pool while they swim, for easy access.
If the waterproof remote control cannot float, it may be equipped with a tether that allows it to be attached to a wrist or stable object outside the water. Also, most waterproof remotes typically have a docking bracket or charging station where they can be stored easily. These brackets are often made to mount on a wall or on the side of an above-ground pool or spa.
Most of these remote controls are encased in pliable plastic that allows for easy gripping. For instance, if an individual with wet hands grasps the waterproof remote control, the soft, rubbery surface is less likely to slip out of his or her hands. The buttons are typically made from the same soft plastic as well.
For the most part, there are two types of signals that these remotes use to control the electronic equipment. IR remotes use infrared waves, and RF ones use radio waves. Typically, an IR waterproof remote control needs to be within the line of sight of the equipment, while RF remotes do not. Some controllers come with both IR and RF capability. Others have a receiver that converts or boosts the signal so it will reach equipment that is on the other side of a wall.
