This camera is a 4G camera and does not run off of wifi. I have a long driveway and my wifi won't go that far. So I got this camera. It comes with a sim card that only has 100mb of data so you can test the product and signal strength. I am very impressed with this camera. Like I said, I put this at the end of my driveway, the fact that is is solar powered is absolutely perfect because I do not have access to electric at the end of my driveway. You can recharge the sim card for as little as $10/mo for 2GB of data. The camera quality is fantastic! I can monitor my neighbors driveway and it's about 1/4 mile away!!! The night vision is excellent for a camera in this price range. This camera uses the UBOX app and has a bunch of different settings that you can adjust to your specific needs. I have my motion detection set on high as there is a delay with the less sensitive settings. However, I live on a deadend street so there is no traffic. I don't think the high setting would be great if you lived in a busy neighborhood. When I get the chance I will be buying more of these camera for the backside of my acerage. The solar panel works great and keeps the camera fully charged all the time. Even they I live in a rural area in Oklahoma the 4G signal strength is pretty good.
