PS. Be sure to test power outages.

Many of those WiFi cameras and systems do not recover from power outages. Just last year I was over in Taiwan working on that issue with a camera maker. That was 2012 and they still had issues with that. It may take years for them to figure out the secret sauce to this. But that one company I worked with did take the provided method and we fixed it. Yes, I do design work in this area so be sure to test for that issue and return products that don't work.
