A video sender (also known as a DigiSender, wireless video sender, AV sender or audio-video sender) is a device for transmitting domestic audio and video signals wirelessly from one location to another. It is most commonly used for sending the output of a source device, such as a satellite television decoder, to a television in another part of a property and provides an alternative to cable installations. Professional film sets use devices like the Teradek to transmit wireless video to a focus puller or a video village.^[1]

A wide range of video sender technologies exist, including analogue wireless (radio), digital wireless (spread-spectrum, Wi-Fi, ultra-wideband) and digital wired (power-line communication). Other, less common, technologies also exist, such as those that use existing Ethernet networks.

Video senders have been a frequent cause of RF interference, particularly with car key fobs.^{[citation needed]}
