My new work laptop doesn't have a built in webcam. I started packing an actual webcam (which is actually my Cisco telepresence camera), but it's made of metal and it's fancy hinged design is a little weird, so it's prompted a bag search on a couple flights lately, to the point where I now just pull it out and put it in a separate bin with my phone/keys/etc.

It occurs to me, though, that I carry an Android phone with two cameras in it, and if I could make my computer recognize it as a webcam, could do away with both the extended TSA visit and an extra chunk of matter in my carry-on.

So, anyone have pointers/recommendations for apps or other methods to make you phone function as a USB webcam? I found a couple apps that run over wifi and bluetooth, but I also don't have BT on the laptop and am not sure if wifi will work since I'll need to be connected to hotel wifi to get to the interwebs.
