The Raptor Monitor app lets you see up to four low-latency video feeds streamed from an on-set Raptor DDR.
Just connect to Wi-Fi provided by your Video Assist service, run Raptor Monitor, then bring your device to the Video Assist operator to request access to their streams.
Double-tap on a window to make it fullscreen, swipe left or right to watch different streams, pinch to zoom in or out, then double-tap again to go back to multi-window view.
A three finger-tap on any window saves a still frame of that video to your photo gallery, or tapping "Grab" saves a still frame of every active stream.
This app is a companion to a Raptor digital disk recorder (https://www.raptorddr.com), and is used for Video Assist (https://en.wikipedia.org/wiki/Video_assist).
