Officially Channel Vision does not manufacture any type of WiFi adaptor. However, based on our knowledge of Sonos, we believe it should have a composite audio input. If it does, you can use the A0316 iPod docking station which will give you a composite audio out (Red/White). This should allow you to transfer the audio directly into the Sonos system. As far as security, we do not manufacture any type of security box, however you can potentially use a clear security case (such as ones used for thermostats) to secure the dock from unauthorized use. This dock is only intended for indoor use, so this application would have to apply purely in an indoor setting.
