A wireless video monitor for iPhone


turns your iPhone®, iPad®, or iPod touch® into a wireless picture monitor / waveform monitor / vectorscope / histogram. See exactly what your camera is doing, without tethering your camera—or yourself—to a hardwired monitor and set of ’scopes.

FieldMonitor works with compatible Panasonic™and Sony™ cameras, or with Teradek Cube, Clip, or VidiU™ transmitters.
  • Full-screen monitoring of your signal, with or without engineering ’scopes.
  • A full range of onscreen markers: frameline and mask with adjustable safe areas and aspect ratios; several grids, center markers, and a customizable crosshair.
  • Focus Assist with variable sensitivity and two display modes (with camera sources only, not Teradeks. On iOS 11, focus assist requires iOS 11.2 or later).
  • Use 3D LUTs to view camera images: use the built-in VLog-to-V709 LUT or import your own .cube LUTs (camera sources only).
  • On modern iDevices, you can also see a fully-adjustable false-color overlay for direct exposure verification.
  • H and V Image Flip.
  • Anamorphic desqueeze support for 1.33x, 1.5x, and 2.0x lenses.
  • With a compatible camera you also get start/stop, exposure, color balance, and focus controls, so you can maintain essential control even while recording.*
It doesn’t matter whether your camera is handheld or on a gimbal, a jib, or a Steadicam. It can be right next to you, in the next room, or out in left field (literally, if you’re using a Panasonic or Teradek and a separate, high-power Wi-Fi access point). If you have a Wi-Fi connection, you can watch your levels, look for clipping, and monitor your color. You can know what your camera is doing, while it's doing it—without needing to run a cable.

Focus Assist gives you fully adjustable in-app sharpening, like an analog peaking control (Focus Assist is only available for camera sources, not for Teradeks).

Focus Assist’s Edge Mode really emphasizes where focus is placed.
