You can use an analogue video sender, but they have several disadvantages. Because they are analogue they cannot transmit HD material. Most also use the overcrowded WiFi bands to transmit on, so lose additional quality, & are also affected by the construction materials of some houses. There are HD senders available, but the cheapest are several hundred pounds.
