The IR 21 and IR22 are small, very efficient allround Infrared illuminators. When used for indoor lighting, they can even be mounted pointed to a wall or corner and light the room indirectly. In that case no light can be detected with your eyes. They are also very suitable for close to mid-range access control with numberplate recognition, or other outdoor purposes. There are dedicated brackets for Mobotix cameras available. A wall mount is included. It can be fed by the active PoE extender/splitter PoE-A-18 together wit a PoE camera over one ethernet cable.
