Wi-Fi WFM

FieldMonitor
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 (FieldMonitor provides a limited set of controls intended to supplement or replace on-camera adjustments while recording under Wi-Fi control. It does not replace Panasonic’s own Image App or Sony’s PlayMemories Mobile for more comprehensive control, configuration, playback, and image transfer).

Before buying FieldMonitor, test with your camera’s native Wi-Fi app: FieldMonitor can’t make your camera do anything that the camera’s native app can’t make it do! If you're not happy with how your camera’s native app performs or the camera controls it offers, you won't be happy with FieldMonitor either.

  • FieldMonitor talks to your camera the same way your camera’s native app does. It will have the same range, resolution, reliability, and latency as the native app. If the native app performs poorly, then FieldMonitor will, too.
  • FieldMonitor only provides the same camera controls as the native app does. For example, if the native app doesn’t allow tap-to-focus, manual focus, face detection, in-camera peaking, or image mag with your camera, then FieldMonitor won't either. If you can’t set the focus point with the native app, you won’t be able to set it with FieldMonitor. If your camera won’t allow log shooting or Picture Profiles with the native app, it won’t allow log shooting or Picture Profiles with FieldMonitor.

FieldMonitor does not provide mode switching, menu control, still image review, image download, or video playback capability, even if your camera’s native app does.

FieldMonitor is designed primarily for video recording. If you are taking still photos, you might prefer something like Cascable instead.

480i to 1080p
No No Cube 100–600 series, VidiU, and Clip only. Latency: 4+ frames @24fps depending on encoder settings.

  • Audio monitoring is not possible with camera sources, only with Teradeks.
  • If your Sony lacks a mode dial to choose between stills and movies, you won't be able to switch modes using FieldMonitor.
  • FieldMonitor (like any other live monitoring and control Wi-Fi app) depends on having a clear Wi-Fi channel for communication. In areas with many busy Wi-Fi networks and/or sources of radio interference, performance cannot be guaranteed. Test for adequate performance using your camera’s native app before buying FieldMonitor!



Screenshots and Videos

Not all features and functions shown are available with every camera, in every mode, regardless of the iDevice being used. Panasonics in manual-focus mode are shown because those cameras provide the richest set of Wi-Fi controls and functions.
  • Panasonics in AF mode and Sonys show fewer focusing controls. You can’t set the focus point on Sonys in movie mode.
  • “Ctrl w/ Smartphone” Sonys do not display focus area, battery level, or storage space.
  • Teradeks have no camera controls, LUT capability, or Focus Assist.
  • older iDevices without A7 or later processors can’t show false color.

Full screen monitoring: camera controls at the edges, plus a focus-area rectangle when the camera provides it (Panasonics and Smart Remote Sonys only, and only in certain focusing modes).

Full screen monitoring


Display one or three ’scopes and set up how they should appear. There are frameline, mask, grid, center, and custom markers, too. You can hide or show camera controls, ’scopes, markers, and other embellishments as you see fit, simply by tapping the screen.

False-color display allows setting each of the color levels (false color requires iDevices with A7 or later processors).

Unsure where your focus is?

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.

The 4-WAY display lets you see all the ’scopes alongside picture.

Many Panasonic cameras offer a peaking control in manual-focus mode (in STBY only for most cameras, though the GH5 displays it while recording).

With Panasonics in manual-focus STBY mode, you can magnify the focus area as both picture-in-picture...

Use a LUT to properly view log images or to apply a look (camera sources only).
