Hollyland Vcore Wireless Video Transmitter

The Vcore clips onto a camera's HDMI output and streams the picture to a phone or tablet over Wi-Fi through Hollyland's HollyView app, so a monitor a shooter already carries becomes the field monitor instead of another accessory in the bag. It passes up to 4K30 to the wired output while the wireless feed to a mobile device runs at 1080p60, with roughly 65 ms of latency, which is close enough for focus and framing checks rather than frame-critical work.

A built-in 5,150 mAh battery runs about 6 hours and can pass emergency charge to a connected device in a pinch. The unit also records a 1080p60 H.264 proxy to its own storage while the phone records in parallel, supports ProRes capture on iOS, and can push a live feed straight to RTMP, YouTube, or Twitch. Wireless range runs up to 350 ft (100 m) line of sight on the 5 GHz band.
