Using a cellular connection instead of Wi-Fi, Defend Security Cameras are made for large properties, remote locations, construction sites, boat and RV sites, or anywhere an extra set of eyes is needed. Battery powered operation means no outlets or wall-power are needed, making the Defend Cellular Security Camera truly versatile. Built to handle extreme weather, and outfitted with a powerful antenna, Defend uses a cellular signal to deliver images and video right to the Defend mobile and web apps, allowing you to see what's happening, even in remote locations.
