[chbot] Group project: Wireless remote security monitor

Interesting...

Some random thoughts...

Why the 10GHz link, what is the traffic, is freq. just for privacy ?

Bluetooth MAC "Bluetooth devices are assigned addresses similarly to 
Ethernet - an organizationally unique identifier (OUI) of 3 bytes 
followed by another 3 bytes assigned by the vendor. The Bluetooth 
address of a given device is almost certainly independent of an Ethernet 
MAC address. Bluetooth OUI lookup tools can be found on Google", from 
the ever popular, and sometimes correct Wikipedia.

Assuming that the burglars are using commercial drones, then presumably 
only one OUI will be used per manufacturer(?) That may allow you to 
exclude a large number of mobile phone manufacturers from the alarm list.

Sounds like you might need a 2.4GHz omi, at some height with a pre-amp - 
assuming you can sniff MACs without having to connect to the device 
(assume Bluetooth devices broadcast their MAC after association, just as 
part of packet transfer).

Not sure if drones will be switched on when passing NZTA's bluetooth 
traffic monitoring system.

Just wondering, if you could design a 2.4GHz sky-pointing antenna, then 
any WiFi or Bluetooth traffic would be interesting to record, since its 
really should all be at ground level.

Saying this all out loud, 2.4GHz traffic received using directional 
antenna, pointing straight up may be a cause for concern.

Lets keep thinking about this...

I've just heard through the grapevine that there are burglars operating 
in the area that utilise a drone for reconnaissance.
