Request from my brother. When target shooting out in the mountains at long range, you can't easily see where you are hitting.
I used a extra FPV quadcopter camera in a watertight box that can be set down in front of the target. You can then view it on a smartphone or FPV monitor.
Here is a detail of the camera mounted inside the box:
The image quality is not amazing but that is to be expected for an FPV camera.
I added a 12v lead acid battery and built in a battery tender for charging.
