The Axis Communications 5500-311 is an antenna kit for use with an AXIS 211W wireless network camera that is installed outside in an outdoor housing. It's best to install this antenna on a wall or mast where it can have a clear line of sight communication with the network receiver. It is also recommended that the receiver itself should be located outdoors since even a window pane can impede wireless performance.
Note! Lightening protector recommended (5500-321)
