I looked at the many options for a wireless camera and I like the
Ring Stick Up Cameraover the others,no monthly fees from the provider and you can put up a solar charger,like I did so you never have to buy batteries.
You get an audio alert on your cell phone when someone or something is in its field of vision,or you can do live view and see what is going on at any time.
The 2 way audio works great and I have used it while more than 300 miles from home to talk to some one at my house.
Their Tech support Team is the best I have ever seen,you can actually talk to someone right here in the US that you can understand.
