Device status (battery level, temperature, SD card usage, etc.) can be viewed in EGOTool.

SD Card Selection and Preparation

A Micro SD card is included with the device, and an SD card must be inserted to record. If you replace it, note the following:

• File system: format as exFAT.
• Capacity: ≤ 256 GB recommended.
• Choosing a card: counterfeit and low-grade cards are common. Fake or incompatible cards can cause the SD card not to be detected or the device not to record.
  • ✅ Tested and working: MoveSpeed A1 V30, Biwin, etc. Buy from reputable sellers.
  • ❌ Known incompatible: some SanDisk A1 / V10 consumer cards do not work with this device.
• Verify real capacity (recommended): before first use, check new cards with H2testw on Windows to confirm the real capacity and avoid corrupted recordings caused by fake-capacity cards.

Power On, Record and Power Off

1. Make sure the SD card is inserted.
2. Attach the magnetic battery. The device powers on and the LED lights up.
3. (Optional) Connect the device to a Windows PC with a Type-C data cable and open EGOTool for live preview — see Connecting EGOTool.
4. Press the record button. A voice prompt announces that recording has started and the LED turns purple. You can also click the Start recording button in EGOTool.
5. When finished, press the record button again. A voice prompt announces that recording has stopped and the LED turns white. Wait until the recording is saved, then remove the battery.

Always stop recording before powering off

Stop recording and wait until the file is saved before removing the magnetic battery. Never cut power while recording, or the data being written may be lost.

Charging

• A fully charged battery lasts about 3 hours.
• When the battery is very low, connecting a Type-C charger directly to the device will not charge it. Remove the battery and charge it with the battery charging accessory.

Connecting EGOTool

EgoSense H6 uses the Windows host software EGOTool for live preview and recording control.

Install EGOTool

• Package: EGOTool_V1.0.3.zip (see Downloads).
• Unzip it — no installation needed — and double-click EGOTool.exe to run it.

EGOTool language

EGOTool currently has a Chinese interface only. The screenshots below are annotated in English, and the EGOTool interface glossary explains every button and field.

Configure the PC Network

Over USB Type-C, the device appears on the PC as a virtual network adapter. Give this adapter a static IP address on the same subnet as the device.

1. Attach the battery to power on the device, and connect the device to the PC with a Type-C data cable.

2. On Windows, open Settings → Network & internet → Ethernet and find the newly added network.

3. Change the adapter's IP assignment to Manual and enter:

   Item	Value
   IPv4 address	192.168.140.21 (any unused address on the same subnet, but not the device IP 192.168.140.20)
   Subnet mask	255.255.255.0

12

1. 1The device adapter shows as "Unidentified network, No Internet" — this is normal
2. 2Set IP assignment to Manual and enter the IPv4 address and subnet mask

Connect to the Device

Open EGOTool, check the settings on the Communication tab, then click Connect device:

12

1. 1Protocol UDP, device IP 192.168.140.20, port 58889
2. 2Click Connect device

Live Preview and Recording

Once connected, EGOTool shows the six live camera views and the device status:

1234

1. 1Live view of the six cameras
2. 2Start / stop recording
3. 3Tabs: Device Control / Encoding / Capture Info / Log
4. 4Device info: name, software version, IP, battery, temperature, SD card usage, system time

There are two ways to control recording:

1. Press the record button on the right side of the device to start / stop recording; a voice prompt confirms each action.
2. Click Start recording in EGOTool.

EGOTool tabs:

Tab	Description
Device Control	Select which camera channels (1 ~ 6) to record and whether to record the IMU.
Encoding	View and set the recording resolution (default 1600 × 1300), bitrate, frame rate, codec (H.265) and container format, then click Save.
Capture Info	Enter task, location, notes and operator, then click Apply. The information is written into the next recording.
Log	View the device log.

See the EGOTool interface glossary for annotated screenshots of each tab.

info

Live preview is only for checking the image, focus and framing — it is not saved. The recording on the SD card is the source of truth.

Exporting Data to a PC

Recordings are saved to the SD card as .mcap files.

1. After stopping the recording, remove the battery to power off the device, then take the SD card out from the rear of the device.
2. Connect the SD card to a Windows PC with a card reader.
3. Copy the .mcap files to the PC. We recommend one folder per recording session.

tip

After copying and checking the data, delete the exported recordings from the SD card to free up space for new recordings.

Viewing Recordings in Foxglove Studio

.mcap files are viewed with Foxglove Studio — no command line needed.

note

The Foxglove screenshots below were taken with the Chinese interface. The English interface has the same layout.

1. Download and install the Foxglove Studio desktop app from foxglove.dev. You need to sign up and sign in with an email address the first time you use it.
2. On the framework selection screen, choose ROS 2:

1. 1Select ROS 2

3. Switch to the tab for playing back recorded data, click Open and select the copied .mcap file (or drag the file into the window):

12

1. 1Switch to the recorded-data playback tab
2. 2Click Open and select the .mcap file

4. The main view is empty after the file opens. Import the layout file Ego-Foxglove-Layout.json (see Downloads): click the layout button at the top right and choose Import from file…:

2. 2Current layout

Topics in the recording:

Topic	Message type	Description
/camera/middle-1/h265, /camera/middle-2/h265	foxglove.CompressedVideo	Front stereo cameras

/camera/right-1/h265, /camera/right-2/h265	foxglove.CompressedVideo	Two right-side cameras
/imu	foxglove.IMU	6-axis IMU data

note

• Foxglove Studio decodes H.265 natively; no plugin is needed.
• You can skip the layout file, but you will need to add panels manually.
• Foxglove Studio is for recorded .mcap files; use EGOTool for the live view.
