Hello People.
Seeing the speaker holes in the back of the V3 camera for the first time made me question how water resistant the camera was. But, it was not of much concern to me because I install my outdoor cameras under the eaves. My major concern was reducing blurry images from raindrops on the lens. A solution I have used in the past for older analog cameras was to tape over or shroud over vulnerable parts of the camera. In the case of the V3, I would make a tape or aluminum foil shroud that would keep rain from directly getting into the speaker holes,
Below are two pictures of an aluminum shroud for keeping most raindrops off of the lens.
The picture below shows the back end of the aluminum bonnet. It could be modified to shroud over the speaker holes. Double sticky tape could be used to attach the bonnet to the camera.
The next image is of a bonnet and a helmet that I developed that can be 3D printed.
