The SMO 4K is a camera developed by BETAFPV and Insta360 for FPV aerial photography. The camera is developed based on the Insta360 ONE R camera.

Preparation Before Using
The power supply range of the SMO 4K camera is 6V-27V, which can be directly supplied from a 2S-6S model aircraft battery. The red wire in the connecting wires in the accessory kit is the power supply wire and is soldered to the battery positive pad (VBat+), and the black wire is the ground wire and soldered to the battery negative pad (GND). Connect the white SH1.0 plug to the power connector of the camera.
Remote Control Configuration
The SMO 4K camera supports remote control of the camera's power on/off and start/stop of the video recording through the controller. The yellow wire controls turning the video recording on/off and the blue wire controls turning the camera on/off.
The following example uses the Betaflight F405 flight controller to explain how to configure the remote control to turn the video recording function on/off. The connection diagram is shown in the figure below. Use the TX1 pin on the flight controller to control the recording, and connect the yellow wire. If you use a different flight controller, different TX pads may be available instead of TX1 and they may use different resource assignments. You will need to adjust the configuration accordingly for your specific flight controller.
Configure the PINIO function of TX1 pin through the following Betaflight commands.
resource SERIAL_TX 1 NONE //Turn off the serial port function of TX1 spindle
resource PINIO 2 A09 //Configure the TX1 pin (A09 pin) as the No. 2 PINIO function
set pinio_box = 40,41,255,255 //Set PINIO function interval
save //Save configuration
The following diagram configures the PINIO function mapping relationship between the remote control and the flight control. In Betaflight Configuration, the PINIO function No. 2 (ie USER2 in the figure below) corresponds to the AUX5 channel of the remote control.
To activate or deactivate functions on the camera, you will need to move the switch from inactive (white area) to the active state (yellow area) and then back to the inactive state (white area).
Your flight controller and radio controller switch configuration must match the setup of your own equipment. Make sure you know what you are doing before configuring. If you do not use the remote control function, cut or insulate the yellow and green wires separately and do not connect to any location.
Install Micro SD Card
Lift the SD card protective cover and insert the Micro SD card with the label facing the side of the camera lens, then restore the protective cover.
Please use UHS-I, V30, or higher versions and exFAT format Micro SD/TF memory cards. Using cards without enough speed may cause recording failure. The maximum size of the Micro SD card this camera can support is 1 TB.
SMO 4K Interface
When the camera is off, press the power button. When the camera is on, the blue status light will be on. When the camera is on, a long-press the power button 2s will shut the camera off. Thus blue status light will also shut off.
When the camera is on, press the recording button to start recording. The status light flashes red. When the camera is recording, press the recording button to stop recording. The status light will turn off.
When the camera is connected to WiFi in the mobile APP, the recording button will no longer work.
The status LED indicates the working status of the camera.

APP Download and WIFI Connection
The SMO 4K camera and Insta360 ONE R camera use the same camera control APP.
Scan the QR code below on your mobile phone, or go to the APP Store and search "Insta360 ONE R" to download the APP.
After downloading the APP and installing it successfully, you can use the phone's WIFI to connect to the camera:
1. Turn on your phone's Bluetooth and WiFi functions.
2. If the camera is off, press the power button to start the camera.
3. Search for a WiFi station with the name of “ONE R XXXXX” by mobile phone, and connect to the WiFi with the password of 88888888.
4. Open the APP and click the camera icon at the bottom of the app page to enter the camera control page. When you see the picture transmitted from the camera, the connection is successful.
5. After a successful connection, you can record videos and set them up through the app.
Note: The effective distance of the WIFI connection is 2 meters (no interference and no shielding). Since the SMO 4K camera has no screen, the WiFi connection process is different from Insta360 ONE R. If prompted "First connection requires confirmation on camera", exit and proceed to step 3 above.
STUDIO Download & Stabilization Processing
The SMO 4K camera uses the same app as the Insta360 ONE R. Go to https://www.insta360.com/cn/download/insta360-oner to download Insta360 STUDIO post-processing software.
Insta360 STUDIO has added an FPV augmenting model for processing SMO 4K aerial video. After importing the video, select "Basic Settings" on the right side, check "Use FlowState Stabilization" and select "FPV" from the FOV Options;
Note: Make sure Insta360 STUDIO has been upgraded to version 3.5.5 or later before using the "FPV" stabilization feature. The stabilization function currently supports only four resolutions: 4K30 4:3, 4K30 16:9, 4K60 16:9, and 2.7K60 16:9.
This camera is customized from the Insta360 ONE R camera and uses the same master PCBA board as the ONE R camera.
