I run blink security cameras at my properties. They work very well. We setup one inside the RV while we where away for a few hours, just to spy on the dogs. It worked very well.
Nice thing about Blink, they run on wifi and batteries, so setup is a breeze.
I have plans to install a blink doorbell at the gate to my property to replace a 1930's telephone style call box. Figured it was time to get with current tech.
