The Niko on/off flush mount motion detector features a unique flat lens that integrates seamlessly in the ceiling. Installation is easy with the innovative Niko patent-pending mounting bracket system, suitable for all types of ceilings. Once installed, the installer can program the sensor completely remotely, using the accompanying smartphone app. All you need is a Bluetooth connection. The sensor was carefully designed. Even technical elements at the back, such as the cable stress relief features, were seamlessly integrated into the design, resulting in a less technical looking product overall.
