Friend,
those brand you post, are China brand products...
In my opinion, there is no different from China brand models or abroad models.
Now the most importance is, which one is the best for you.
1. your wifi signal is very well outside, that means, wifi camera could work very well there.
2. motion detected, I think now most of the wifi camera would have this function, it would be easy to match your require.
3. outdoor use, you need weather proof. hot,rain,snow and other which would affect the eyesight, you need to consider the resolution and definition.
Any further help you need, could directly contact me:

Hope it would help you, thanks
Wish you a nice day
