Meet the GoPro HEROCast : a lightweight, micro transmitter that lets you deliver live content with POV footage to your audience. It works with your GoPro camera and lets you deliver 1080/60fps and 720/60fps video using H.264 encoding. It connects to a GoPro camera via a lockable HDMI cable. The HEROCast BacPac connects directly to your camera and has a rugged, waterproof design.
Both HEROCast BacPac and HEROCast are compatible with HERO4 and HERO3+ Black cameras. They last for up to 40 minutes on a fully charged battery. These each cost $7500.
