I have eufy battery operated wifi cams because I also didn’t want to run wires. They are okay. Sometimes detect cats and raccoons, but sometimes they don’t. Picture quality is fine. Just don’t expect wired-level quality, detection, accuracy, or features. I have one base unit and several cameras outside. The big plus is setup takes minutes, but you give up on other areas. If you just want to see what’s happening in your backyard they should do the trick for not that much money. And easy set up. 

There’s some controversy about eufy security, and where video is stored or something with Eufy cameras, but for what I use it for I’m not concerned. Plus, everyone is recorded almost everywhere you go by neighbors and kids with phones etc. etc. 

I got this set at Costco.

If you have any other questions about the eufy set up, just let me know.
