One solar panel per cam, it's expensive but great

Is this solar panel also compatible with the Pro2? I have read that it sucks the battery dry with the Pro2 instead of charging it. It is not clear whether it is defective or not compatible.

For me, it's enough for 2 cam absolutely lowest level was 45% for the third 20% battery but within a week back to 100%. I have never had to arrange for additional charging. But it certainly depends on the location. Therefore, the longer the shade, the less charging. 2-3 hours of sunshine per week is enough to keep the battery sufficiently charged.

I would take 2, as the two plugs (1x panel, 1x cam) are optimally adapted and thus prevent water from penetrating. It's best to do a few tests to see how much power each cam eats up and how much the panel produces. Both cams are now running at maximum resolution and maximum acoustics. The two panels easily charge the cams even in foggy Aargau.
