Loop recording： Off、1、3 minutes. When the SD card is full, video will be auto loop recording. When the SD card is full, video will be auto loop recording. The oldest file will be deleted first.
WDR： Off、On. WDR effect will be On/Off. Note: When this function is turned on, the image will not become dark even toward the sun. The image would not looks so clear if this function is ON sometimes. As a FPV cam, this function should be turned ON.

Triggers:

The trigger pins need to be connected to the trigger control cable. Scan to watch.

Note: Don’t connect the trigger pins to any power. If you want to control it by a MCU, connect it to a 3.3V GPIO through a 1K resistance.

Installation:

Soft mount is needed between the camera and the drone frame. Use TPU Mount or 3M double-sided tape.

Record videos:

Please insert SD card, then press Power/OK button once to record. Please use
U1 speed SD card at least(8-64G). Format the SD card to FAT32 in the camera at the first time.
Press OK key to stop recording before unplug the power.

Remote control to record video 1:

The following example uses Betaflight F405 flight controller to illustrate how to configure the remote control to turn on/off the video recording function. Use the TX1 pin on the flight controller to control the recording and connect the Naked Cam’s Blue wire(video trigger). If you use other flight controllers, there may be available TX pads instead of TX1, and they may use different resource allocations. You need to adjust the configuration accordingly for your specific flight controller.
Configure the PINIO function of the TX1 pin through the following Betaflight commands.
resource SERIAL_TX 1 NONE // Close the serial port function of TX1 spindle resource PINIO 2 A09 // Configure TX1 pin (A09 pin) as PINIO function No. 2 set pinio_box = 40,41,255:255 // Set the PINIO function interval Save // Save configuration
The following figure configures the PINIO function mapping relationship between the remote controller and the flight controller. In Betaflight configuration, PINIO No. 2 function (ie USER2 in the figure below) corresponds to the AUX5 channel of the remote control.

To activate or deactivate functions on the camera, you need to move the switch from the inactive state (white area) to the active state (yellow area), and then back to the inactive state (white area). To
The switch configuration of the flight controller and radio controller must match the settings of your own device. Before configuring, make sure you know what you are doing. If you are not using the remote control function, please cut off or insulate the yellow  and green wires separately, and do not connect them to any location.

Remote control to record video 2:

Connect the FC’S LED PIN to Hawkeye 4K naked Blue wire (Video trigger pin).

Change the LED pin to GPIO through betafligh command. (Backup all the settings before modify)
resource LED_STRIP 1 NONE // turn off LED function
resource CAMERA_CONTROL 1 NONE // release CAM function
resource CAMERA_CONTROL 1 A00 // set LED（A00 PIN）to cam control save // save settings
Throttle set middle，pitch push down to trigger recording（ Note: don’t push to other direction)

Notes for Gyroflow:

1. Use essential matrix:
2. Select Dynamic zooming, then there will be no black side.
3. Sync time change to 3-5 second:
4. Sync points should be similar number, if its too different, delete it and add a sync point on other point(right click on the mouse).
5. If can’t export video , turn GPU off, change to H.264.
6. Software require Win 10,11. If can’t open the software, install the VC pack:
   VC_redist.x64.exe.
