Arlo's latest cameras can run for up to six months on a single charge

Arlo has announced updated versions of two of its wireless security cameras. The $199.99 Pro 4 can capture 2K HDR footage in a 160-degree field of view. It connects directly to WiFi, so it can work as a standalone camera. However, you can integrate the Pro 4 into an existing Arlo setup by connecting it to a SmartHub or base station. The Ultra 2, meanwhile, boasts 4K HDR video capture along with an ultra-wide, 180-degree field of view.
