George needs security cameras for his house. Leo says that the Wyze Cam is a good one, but a doorbell cam will stop package thieves dead in their tracks. There are two kinds: the Nest or Ring camera. They connect to the same power source as his doorbell, and he can get connected with his mobile device. The he can interact with the person on camera. It'll also record to the cloud. But he would need Internet.
There's also the Arlo Go, which doesn't need power or internet to use since it has its own LTE service.
