The Arlo Ultra is the security camera brand’s most powerful device yet. It features a 4K Ultra HD resolution sensor with high dynamic range (HDR), a 4K lens with a 180º field of view and it has an integrated spotlight that lights up anyone or anything that moves within its view. There is also audio detection that listens for odd noises. When something suspicious is seen or heard it can sound a screeching siren and even call 911. Comes with a 1-year subscription for storing your footage.
