Hotgen
Hotgen primarily specialised in Toys and Drones. Two of the project I worked on there were SkyViper, a toy drone and Mebo2.0, a toy, remote-controlled robot.
Both products supported streaming video back to the app, but only Mebo 2.0 allowed you to directly control the toy (Sky Viper was controlled with a separate controller). Both apps allowed the user to take snapshots and record from the camera.
