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.
- Full-screen monitoring of your signal, with or without engineering ’scopes.
- 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 four peaking modes (for camera sources only, not Teradeks. On iOS 11, focus assist requires iOS 11.2 or later).
- 3D LUTs to view camera images: use the built-in LUTs 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; Image Rotation.
- Anamorphic desqueeze for 1.33x, 1.5x, 1.8x, and 2.0x lenses, with H/V selection and a desqueeze ratio adjustment.
- 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 Canon’s Camera Connect, Panasonic’s Image App or Lumix Sync, or Sony’s Imaging Edge Mobile for more comprehensive control, configuration, playback, and image transfer).

- Audio monitoring is not possible with camera sources, only with Teradeks.
- If your camera lacks a mode dial or switch 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
- Panasonics in
manual-focus mode 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 most Sonys in movie mode.
- Many “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 with A6
or earlier processors can’t show false color.
Typical Panasonic controls in manual-focus mode. Panasonics send storage and battery-level information. Camera battery level shown with PWR: label, iDevice battery shown with the i: label.
Typical Sony controls in manual-focus mode. This Sony does not send storage or battery information, and the AF button only works in AF mode. iDevice battery shown with iPWR: label.
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.
Focus Assist demo:
Anamorphic support? Sure! Pick your lens and your final cropped aspect ratio.
Desqueeze Adjustment lets you fine-tune the squeeze ratio:
The 4-WAY display lets you see all the ’scopes alongside picture. A tap of the screen hides controls for a clear view.
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...
...and as a full-screen image.
Use a LUT to properly view log images or to apply a look (camera sources only).
