I started out with the doorbell. I then purchased a. S340 for one side of the house and now just purchased a second one. I have a total of nine cameras in and outside the house. I love them all especially the S340 as it tracks people as they are moving around the yard and has a zoom lens. This works better than the pro model I have in the backyard. But the pro model covers a smaller area so it’s not a big deal. Would definitely recommend all of the UV products. Very simple installation. I recommendation is to get the hard drive upgrade by purchasing at least for terabytes so you can have plenty of memory for cameras you want constant recording on. I found a 4 terabyte hard drive on Amazon for $129.
This is my second purchase of the E340 to add to a second home. Eufy option to stand alone or purchase a subscription service is why I like Eufy products. The Eufy E340 is a quality product and I use it with the Eufy HomeBase 3801 which allows facial recognition. The system is easy to install and training the facial recognition is also easy.
