Vacos Cam review: This promising security camera is handcuffed to a mess of an app

Battery-powered security cameras are a great option for outdoor use, because they remove the logistical hassle of finding a convenient electrical outlet to power them. But their easier installation comes with a cost, as they tend to be priced higher than their AC-powered counterparts. The $139 Vacos Cam would seem to be the best of both worlds, then--supremely flexible, modestly priced. Unfortunately, testing revealed this camera to be far from a polished product. While its video quality and smart motion detection are solid, its barely baked app makes the camera virtually unusable. The camera is the latest to crib its look from the Arlo line of home security cameras, in this case the Arlo Go (except that camera connects to the internet via an onboard LTE radio).
