I'd think a pringles or coke can would be a bit less conspicuous..
On the other hand you know those security video cameras used in public places which can be remote controlled to rotate and zoom in on someone's face? They are usually hidden in smoked glass domes in ceiling or, I suppose, in less conspicuous ways in places like casinos or board rooms. Sounds like another good aiming device, I saw one $500 dollar model in Akihabara recently you can operate from a web page. Same shop for a few hundred bucks also sold remote cameras accessible via UHF.
I'd be worried if I carried anything with Bluetooth (so far I've resisted..) The more it penetrates it seems the more tiny yagi antennas you'll see. Only saving grace I could imagine is if the yagi antenna is left powered up maybe you could detect it as the camera pans across you... IANA EM Engineer but would not a yagi antenna also transmit towards you any noise from say the video camera's motor or power supply? If so a detector might be in order..
