The Arlo Go records HD at 720p. Although this is lower than other cameras in our buying guide, many of us don't really need best in class 4K recording on a security camera especially if you're trying to transmit that kind of data via 4G. It also has a bunch of solid recording features, including motion sensing, timing options and geo fencing, which turns the camera off when you're on your way home. The main downside is that it won't get perfect 4G coverage everywhere, especially in the countryside where good 3G is sometimes hard to come by. And if it doesn't have it, it just stops working as there's no option to use a mobile hotspot or to connect to Wi Fi as a back up. 88 View at Amazon$268. 15View at WalmartRecommended Retailer$299View at Google StoreSee all prices 92 found?Fantastic build qualityVery high video qualityReally is a smart cameraFull functionality requires subscriptionsThe Nest Cam IQ has IQ in the name for a reason: it’s intelligent.
