A WiredNews article about hackers and spy cams could portend problems with remote warfare against a technologically advanced adversary that might, say, have a government-sponsored Tiger Teams (and here)?
The Wired article focuses on Axis cameras that can remotely controlled and their images edited. Back in Oct 2005, Yorkshire Ranter shed the same light on the issue, along with technical details.
A quick google search turns up an airport cam, a swiss cam, and others. Search for yourself using this Google search (which will only bring up Axis cameras not properly protected on the Net).
I did not find anything interesting but the technology warning is
ever present: be careful with technology because nothing is secure.
