This Eufycam 3 pack contains 1 IP camera, a video doorbell, and the HomeBase 3. The Eufycam 3 is the latest Eufycam. The advantages over other Eufy cameras is that the EufyCam 3 records in 4K resolution. It also has a solar panel, so you charge it less often. The E340 doorbell works wired, or wireless. It has 2 cameras, so you can see visitors from head to toe. The doorbell and cameras use the artificial intelligence of the HomeBase 3, which allows people to be recognized. Images are stored locally on the base station, and not on the Eufy servers. The range of the Homebase has increased, so the signal remains good at greater distances from the base station. The base station also works as a chime for the doorbell.
