I saw this down the stairs at the beach the other day - newly installed. This morning while I was out for my run I noticed another similar one set up on another light post about 1/2 mile down. It's got a "Cisco" label on it so I'm wondering if it's some kind of wireless surveillance equipment or something. WiFi down the beach makes no sense (and I haven't picked up any new signals on my laptop wireless card, so I doubt that's it). So WTF is it and what's it for?

Sorry for the crappy cell-phone camera pics - it's all I had with me.
