Arlo Ultra 2 offers ultimate security through the power of precision. The surveillance camera captures 4x more detail, so you can zoom in 12x on key features without distortion to identify a suspect - even at night. Receive alerts directly to your phone when motion is detected so you can respond quickly to activity at home. Set your siren to go off automatically or activate it by phone when your camera notifies you of an intruder. With twice as many frames per second compared to 1080p video, the Ultra 2 captures even the smallest details so you can identify the exact moment of activity. With the Arlo Smart security subscription, video surveillance footage is recorded and securely stored in the cloud in 4K for 30 days, so you can view all the details afterwards and use them as evidence.
