Whether you are taking stills or recording video, you will need a way to monitor from the ground to compose your shots. Many purpose-made aerial cameras have some form of video transmission built in. Or you can pick up a separate video transmitter and receiver set. Either way, this can be an old-school analog 5.8 GHz system or a digital system that is either 5.8 GHz or, more likely 2.4 GHz. Analog 5.8 GHz systems still have the longest range out there, and can hold up to weak signals better. On the other hand, the quality isn't going to be spectacular.
