What’s the maximum range between the Base Unit and accessories?

Because Sphere deploys a proprietary wireless communications system, the distance between any of the sensors, detectors, sirens, keypads or remotes and the Base Unit can be as far as 656 feet (200 meters). Walls and floors can diminish the distance while open areas may increase it. The indoor and outdoor cameras, however, have higher data requirements since they transmit video. The cameras are linked through your wireless router, which typically offers about a 300-ft. (91 m) reach. (Wi-Fi coverage always can be extended by adding equipment.)
