Give it a try first. Sometimes a good daylight filter can do it.
I do not have special recommendations for a webcam.
The cheapest can do the trick. You just need a low resolution with 30FPS, weak or removable ir-filter and deactivatable autofunctions.

...look for a recent model as Win8 do not support some older cams any more.
Some recommend the PS3Eye cause of there 60FPS but there are still problems with the driver in some case. If you can get it for a decent price try it.
