I just got an email out of the blue for a free trip to Taiwan. We don't do such things (conflict of interest, waste of time to be on such a dog and pony show, etc.).
Here's the agenda including scheduled meetings with D-Link, Vivotek, Geovison, Everfocus, Plustek, Avtech, Aver, Planet, and more (but interestingly not ACTi).
Given Taiwanese companies lack of coverage, I can see this being a smart move to incentivize security media to be aware of them. If they can get some coverage for the ~$5,000 this costs per person, it's probably a good investment for them.
