I was in the market for a security camera that would be suitable for the construction site of a new home, that had no electricity nor Wi-Fi service in it. After lots of research I came across the Eufy 4G LTE Cam S330 after further examining the product I ordered it, and I don't regret it. I would rate this security camera 4 out of 5 stars because it was easy to set up and install, it has seamless connectivity, and some other amazing features.The setup took me less than 10 minutes all you must do is download the free Eufy Security app on your phone (compatible with iOS and Android) and follow the directions on the app. You do not even need to have Wi-Fi to set up the camera because, with the SIM card, you can practically set up the camera anywhere. The camera comes with almost everything you need to install it, the only things you will need to have is a screwdriver and maybe a ladder depending on where you would like to install it. Depending on the surface you wish to install it you might need some screws for example I installed them on siding, and it was a struggle to screw the screws in, so I had to get some screws for siding, but I guess it is different for everyone. Another good thing is the size of the camera. It is not too big but also not too small (approximately 4in.x4in.x6in.). It is a perfect size to where people can tell you have a security camera making intruders think before stepping foot on your property.Seamless connectivity allows the camera to continue operating even if you don’t have Wi-Fi. The camera comes with a SIM card, that you can activate when setting up the camera, it is compatible with 3 major US networks: AT&T, T-Mobile, and Verizon. The camera automatically selects the network with better connectivity to enhance its performance. It also comes with a 100MB of Trail data in 7 days. One downside would be that you must pay after the trial is over, kind of like a cellular plan, if you wish to continue using the SIM card. The SIM card subscription ranges from 50MB 30 Days for 7$ to 50G 360 Days for 229.90$.The Eufy security camera also has a great number of features such as 4k viewing both day and night, notifications to your phone with an optional small video clip of the movement it detected, 360 viewing with AI tracking meaning that once it detects someone it will follow their movement, two-way audio, light and sound alarm that you can activate on your phone and it is solar powered. These features are excellent because I can see who is at the site, hear what is happening, and scare unwanted trespassers without physically being there and not having to worry about the camera’s battery running out. The Eufy app helps make it easy to control all these features by allowing you to control and move the camera from anywhere, allowing you to view live video, and if you wish you can record or screenshot a certain live moment and it will save to your phone’s cloud. This helps you from having to physically go and move the camera by hand and having limited access to certain angles.In conclusion, I would 100% recommend this product. Especially for anyone who is looking for security cameras for an environment where Wi-Fi access and electricity are hard to access. Yes, there might be cheaper options out there but overall, the price matches what you are getting I have had the opportunity to try Night Owl and Google Nest cam, and I would 100% choose the Eufy security camera over both anytime.
