How To...


Connect FieldMonitor to a source

Tip: turn Airplane Mode on, then turn Wi-Fi back on. You'll improve display performance and battery life and reduce interruptions from calls, messages, and notifications.

Direct connects your iDevice to the source’s Wi-Fi radio directly. It‘s easy, but camera radios are weak and limited in range and performance. All sources allow direct connection.

Via Network uses a separate Wi-Fi access point or router: you connect your source and your iDevice to the access point. Via Network allows greater range because the access point’s radios are more powerful, but you need to bring the access point on location and provide power to it. You can operate several sources on the same network and switch between them without having to change theß network on your iDevice. Only Canons, Panasonics, “PC Remote” Sonys, and Teradeks connect via network.


Canon cameras, direct connection

Before connecting FieldMonitor to a Canon, check three settings in the camera’s SHOOT menu:

Canons manage connections to different apps and/or devices individually. On some cameras, each connection is a “set”; on others you “register a device for connection” or “add a device to connect to” when you first connect a remote app to the camera. If you use FieldMonitor running on two different iDevices at different times, that’s two different connections. If you run Canon Camera Connect and FieldMonitor on the same iDevice at different times, that also counts as two connections. To keep track of the different connections, give each copy of FieldMonitor its own name, for example “FieldMonitor-SE” for a copy of FieldMonitor on an iPhone SE, and “FieldMonitor-Air” for FieldMonitor on an iPad Air. Some Canons will use these names automatically when a new connection is registered; with others, you'll need to manually edit a “set” name to identify it properly. Some cameras can only remember three sets of connections; if you need more, you will need to re-use a set or sets.

If you try to connect to a Canon using a different connection setting (for example, the setting used for Canon's Camera Connect app, or for FieldMonitor running on a different iDevice), FieldMonitor may say “Camera refused connection.” You must set up different connections for different apps, and for different iDevices. If FieldMonitor says “Press OK on the camera to allow FieldMonitor to connect”, but your camera is not showing a “Connect to this smartphone” screen with an OK button to press, your camera is expecting a different connection. Either change the connection on the camera to the one set up / registered for FieldMonitor, or configure a new set / register a new connection for FieldMonitor.

Different Canons have different ways of setting up connections; see your camera's User Guide or Wireless Function Instruction Manual and look for the “Connect to a Smartphone” instructions, using FieldMonitor instead of Canon’s Camera Connect app.  The instructions below are a rough guide only: your camera’s menus may be arranged differently and may use different terminology for the same functions. Many cameras have their wireless communication settings in the yellow SET UP menus as shown below; others have a dedicated purple NETWORK menu.

Here’s the direct connection process on the EOS 80D. If your camera’s menus are more like those on the EOS RP, the RP is shown below. Otherwise, see your camera’s User Guide or Wireless Function Instruction Manual.

On your camera, press the MENU button, and navigate sideways to the SET UP menu showing Wireless communication settings:

Select Wireless communication settings, and make sure Wi-Fi is enabled:

Then select Wi-Fi function...

...and Connect to smartphone:

Select Easy connection:

The camera will display the camera’s SSID and encryption key:

Use the Scanner to connect to the camera (iOS 15+; not available on Mac), or connect manually.

To connect manually: In your iDevice’s Wi-Fi settings, log into that network, using the encryption key as the password:

When your iDevice connects to the camera, the camera will show this screen:

Open FieldMonitor (not Camera Connect!).

Your camera should appear in the Source list. If not, tap Refresh. When the camera appears, tap it:

The Monitor window opens, and this message appears:

On the camera, confirm the connection by selecting OK:

The camera will allow FieldMonitor to connect, and the live-view image should appear.

The next time you wish to connect, you just need to make sure the camera’s Wi-Fi is turned on (on the 80D, it's on by default until you turn it off). Connect to the camera's network, open FieldMonitor, and start working. If Wi-Fi is off, when you choose Connect to smartphone, you'll get a screen that lets you choose, change, or delete settings; choose the setting that corresponds to FieldMonitor and press Connect to start the camera’s network.

Connection “sets” on the 80D are labeled SET1, SET2, and SET3 by default. Rename them to make picking the correct set easier. For example, I renamed SET1 on my 80D as “FM-SE”, as that’s the set that FieldMonitor-SE connects with.


Here’s the direct connection process on the EOS RP.

On your camera, press the MENU button, and navigate sideways to the settings menu showing Wireless communication settings:

Select Wi-Fi function:

You will see this “connection type” screen if this is the first time you have registered a device:

If you already have devices / apps registered, you'll see a screen showing your existing connections:

Choosing one of these will set up the camera for that connection. To register a new connection (as you need to do the first time you run FieldMonitor), select the right arrow or press the right side of the 4-way controller to get to the connection type screen.

Fujifilm cameras

Fujifilm cameras go completely dead when under Wi-Fi control, so adjust any menu or dial settings before starting Wi-Fi. These include still photo and movie formats; film simulation, F-Log, and HLG settings; and image quality adjustments. Once FieldMonitor connects to the camera, you will be able to switch between photo and video modes, adjust exposure and white balance controls, and set AF points in photo mode only using in-app controls, but no on-camera controls will work.

On your camera, press MENU/OK and find WIRELESS COMMUNICATION (usually towards the bottom of the SHOOTING  submenu):

Wireless communications menu item

Select it. The WIRELESS COMMUNICATION screen will appear. If the camera was previously connected to a Wi-Fi controller, such as Fujifilm Camera Remote, the screen will look something like this:

Wireless Connection screen with previous controller listed

Important: if you last controlled the camera using a different app or a different iDevice, press (OK)CHANGE (the MENU/OK button) to make the camera forget the last controller. If you don’t do this, the camera will not appear in FieldMonitor’s source list.

(If you wait to do this until after you have connected to the camera’s network and started FieldMonitor, tap FieldMonitor’s Refresh button to try talking to the camera again.)

Here's the WIRELESS COMMUNICATION screen when the camera isn't expecting a previous controller:

Wireless Connection screen without a previous controller

Use the Scanner to connect to the camera (iOS 15+; not available on Mac), or connect manually.

To connect manually: On your iDevice, go to Settings > Wi-Fi and connect to the camera’s network:

Connected to Fujifilm Wi-Fi

Close Settings and open FieldMonitor.

The camera should appear in the Source list. It may up to five seconds to appear; if it takes longer, tap Refresh.

Connected to Fujifilm Wi-Fi

If the camera doesn’t appear after five seconds, see if the camera’s WIRELESS CONNECTION screen has an (OK)CHANGE option:

Wireless Connection screen with previous controller listed

If so, press the MENU/OK button on the camera, then tap Refresh in FieldMonitor.

After your iDevice talks to the camera, you may see a screen like this on the camera:

Wi-Fi connection conformation request

Press (OK)TRANSMIT (MENU/OK button) on the camera to allow FieldMonitor to connect.

Once FieldMonitor connects to the camera and it appears in the Source list, the camera’s status LED flashes yellow and green, its display turns off, and no controls on the camera will function — you must perform all camera control using the app.

Tap the camera in FieldMonitor's Source list to open the Monitor screen so you can view and control the camera.

Do not turn off your iDevice while you are controlling the camera remotely. Turning off the iDevice or interrupting its Wi-Fi connection causes the camera to shut down. If you switch to a different app and that app consumes a lot of resources, iOS may terminate FieldMonitor in the background, and cause the camera to shut down. If the camera shuts down, restart the camera by turning its power switch off, then on again.


Panasonic cameras, direct connection

Connect your iDevice directly to the camera, using the camera’s own Wi-Fi network. This is the simplest connection method and it often works well, though “via network” connections can offer greater range and better interference rejection using a high-performance access point.

Sony “PC Remote” cameras

Wi-Fi-capable “PC Remote” cameras include the A7Riv.

A7Riv screens are shown. If your camera’s menus look more like Smartphone Connect or Smartphone Connection menus, there are similar processes, but the steps will vary depending on the your camera.

Do not select “Send to Smartphone” or “Send to Computer” in the camera’s menus. These functions are only used to transfer images; they do not allow remote control.

Press MENU and select the Network tab with “PC Remote Function” in it:

Select it, and go to page 2:

“Still Img. Save Dest” defaults to “PC Only”: the camera will not save stills on the camera but send them to the remote-control program. FieldMonitor does not save these stills, so change this to “Camera Only” so that photos taken by remote control will be saved on the camera (if you don’t change it, you won’t be able to take still pictures. If you change it to “PC+Camera”, stills will be saved on the camera and sent to FieldMonitor, but all that does is waste time, since FieldMonitor ignores the transmission). This setting only affects still pictures; video clips are always recorded on the camera.

Then return to page 1, and set “PC Remote Cnct Method”. If you set it to “Wi-Fi Direct”, you can then turn “PC Remote” on and connect to it directly, just as you would using Ctrl w/ Smartphone connections.

Instead, set it to “Wi-Fi Access Point” so that you can connect to it via a separate network:

If you haven’t connected the camera to your network before, you”ll see this screen:

You can use the WPS connection method if your access point supports it, or you can choose the access point directly:

When your access point appears, select it in the list:

If you need to enter a password, you’ll see this screen:

After you have entered the password, press OK to connect:

You can leave the IP Address Setting and Priority Connection settings alone and press OK:

When your camera connects successfully you’ll see this:

Press OK and you'll be warned that you’ll need to “Pair” FieldMonitor to the camera. You should only need to do this the first time you connect.

Then turn “PC Remote” On:

Select “Pairing”:

You will see a screen like this:

Connect your iDevice to the same network, and open FieldMonitor:

Tap on your camera’s name to select it. The Monitor screen opens, and you should see this message:

The camera’s display will change to show this screen:

Press OK, and the camera will “pair” to FieldMonitor. The camera will then send live-view images and give you remote control.

PC Remote stays On until you turn it off in the camera’s menu. The next time you want to connect to the camera, tapping the camera’s name should launch the Monitor window and immediately give you a live view and remote control. You don't need to pair again unless you switch to a different iDevice or reset the camera’s network settings.


Teradek H.264 transmitters

Set your Teradek to transmit RTP/RTSP, Quickview, Live:Air, Airmix, or TDS streams. RTP/RTSP and Quickview, when available, are the fastest to connect and the most energy-efficient. Quickview must be set to RTSP (not Airmix, when the option is available). If using HEVC encoding, RTP/RTSP streaming must be used. Authentication cannot be enabled when using FieldMonitor.

Direct or “Master” mode allows direct connection with no other hardware: you connect your iDevice to the Teradek’s Wi-Fi directly. See Teradek’s documentation for setting up “Master”, “Ad Hoc”, or “Access Point (AP)” mode.

“Client” or “Infrastructure” mode uses a separate Wi-Fi router or access point. Client mode often allows greater range because the router’s radios are more powerful, but you need to bring the router into the field and provide power. You can also operate multiple sources on the same network and switch between them without having to change the network on your iDevice. On your Teradek, select “Infrastructure” or “Client” mode, and connect to your Wi-Fi router. See your Teradek's documentation for details.

On your iDevice: Settings > Wi-Fi > [Choose the network]. The first time you do this, you may need to enter the password for the network. Then open FieldMonitor and tap the Teradek’s name to select it (if your Teradek doesn’t appear in FieldMonitor’s list, tap Refresh).


Hide or Show onscreen controls

Tap the screen to hide controls and data overlays; tap again to display them. To change what gets hidden, tap display controls , tap Hide, then turn hiding on or off for controls, ’scopes, markers, etc.


Show and adjust ’scopes

Tap display controls , tap Scope, then choose the ’scope(s) to be displayed. In any mode where ’scopes overlay the picture, simply drag them to new positions, and pinch them larger or smaller.


Show and adjust markers

Tap display controls , tap Mark, then tap the marker type you want to adjust. Use the Show switch to turn it on or off. Use Show Color / Show Controls to toggle between display and color settings.

You can change the aspect ratio and safe area options available for Frame markers in the Settings menu.

Check focus

Tap display controls , tap Image, then adjust Focus Assist Intensity to the desired level. Type controls the type of focus assist: ANALOG shows a standard peaking signal; EDGE shows a reduced-contrast picture with a bright edge-detection signal; DIGITAL shows a digital peaking display in red or cyan. (DIGITAL requires iOS 10 or later. Teradeks: Convert Images to RGB must be ON to use Focus Assist.)


Check exposure

Use the Y WFM to see where your levels are. You can use FieldMonitor to watch exposure as your camera moves through a scene, checking for overexposure. 

If your iDevice supports false color, set the false color levels to show you over- and under-exposure warnings, and/or use the green level as your target exposure value.

Otherwise, you can use false-color LUTs with camera sources; just be aware that ’scopes measure the image with the LUT applied, and a false-color LUT will cause the ’scopes to show wildly inaccurate results. Turn the LUT on for false-color, turn it off to use ’scopes.

Note that ’scopes and false-color display for Panasonic sources may not be accurate unless FieldMonitor’s levels settings match the camera’s.


Check color

Use the RGB WFMs or the vectorscope to look at color.

When the camera is aimed at a white card, gray card, or grayscale, and is properly white-balanced, overlaid red, green, and blue waveforms will superimpose and turn white. On the vectorscope, the center dot will be properly centered in the crosshairs.

When the camera is aimed at a bluescreen or greenscreen, you can adjust exposure while looking at RGB WFMs or color histograms, checking for the best separation between your key color and the subject’s colors.

Electronically-generated colorbar vectors should fall in the vectorscope target boxes at either the 100% setting (typically EBU full-frame bars, or the fully saturated red/blue/cyan/yellow patches on ARIB bars) or at 75% (SMPTE and ARIB bars).

When shooting a DSC Labs chart with a “V/S Gain x 2” marking, or a Gamma & Density Log chart or Gamma-709 chart, use the 2x setting. In an ideal world, a perfectly set-up camera will put the chart’s vectors into the target boxes. (Unless you’re using a broadcast camera this probably won’t be the case; most cine cameras, camcorders, and DSLR-style cameras use different color and tonal-scale renderings, and the vectorscope pattern often will not match the layout of the target boxes precisely.)


Use LUTs

Select up to three LUTs in the Settings menu after you have imported them. Then, in the Monitor screen, tap the control button , tap Level, and choose the LUT you want to use. (Teradeks: Convert Images to RGB must be ON to use LUTs).


Import LUTs

FieldMonitor can import 3D LUTs in .cube format using iOS file sharing, Finder (macOS 10.15 or later), or iTunes file sharing (Windows, macOS 10.14 or earlier). If you’re running FieldMonitor on a Mac, see below.

iOS file sharing: Email yourself a .cube file or put the file in iCloud Drive. On your iDevice, tap and hold it to reveal the iOS sharing sheet, and select “Copy to FieldMonitor” (or “Import with FieldMonitor” in iOS 10 or earlier). FieldMonitor will launch and import the LUT, after which it will be available in the Settings menu's LUT selections:


A .cube file in an email (the icon shown may vary). Tap and hold it to open the Share Sheet.

Find FieldMonitor in the Share Sheet. Tap it to import the LUT into FieldMonitor.

FieldMonitor launches, and imports the LUT.

LUT loaded into FieldMonitor

(If FieldMonitor is already running in the background but is not at the Source screen, you won’t see the “LUT Import done” message when FieldMonitor appears. Return to FieldMonitor’s Source screen, go back to Mail, and tap “Copy to FieldMonitor” again.)

Now you can assign the LUT to a one of three positions for immediate use.

LUT ready for use

Finder: Connect your iDevice to your Mac and select it in Finder. Choose Files, then drag .cube LUT files onto FieldMonitor:

.cube files added in Finder

iTunes file sharing: Connect your iDevice to iTunes and view its settings. In iTunes 12 or later, select File Sharing in the sidebar, then select FieldMonitor in Apps. Drag .cube LUT files into FieldMonitor Documents:
 .cube files added in iTunes

In iTunes 11 or earlier, select Apps in the sidebar, scroll down to File Sharing, and select FieldMonitor. Drag .cube LUT files into FieldMonitor Documents:

.cube files added in iTunes

If FieldMonitor is running, tap Refresh on the Source Screen to read the .cube files and turn them into .fmlut files. Otherwise, FieldMonitor will read them the next time it is launched. This video shows the process with iTunes 12+:

.fmlut files are FieldMonitor LUTs. If you delete them while FieldMonitor is running, please tap Refresh on the Source Screen to let FieldMonitor know you’ve deleted them (otherwise, if you try to select one in the Levels controls, it will be displayed as NG — not good — and no LUT will be applied).

If you’re running FieldMonitor on a Mac:


Find LUTs


Launch FieldMonitor from another app

In Apple’s Shortcuts, simply select Create Shortcut, Add Action, Apps, Open App, and choose FieldMonitor. To open FieldMonitor from an app like Launch Center Pro, use the URL scheme “fieldmonitor://”.
