The stick up cam is quite neat. It was easy to set up and so at has been reliable. I bought the wired one, which you plug in a regular wall outlet. I wish it had a battery as a back and also to be able to easily move it to a different location temporary. 
I have it on the inside of my window and unfortunately at night, it cannot see outside because of the reflection from the glass. 
It was a little pricey.
