Whelp Watch

I was wondering if you could all recommend what web cams you have bought to use and/or best for usage for Whelp Watch. How long a cord can I run between the laptop(its wireless) and the actual cam? We do have a very good router in the house but my apartment is in the back and I can't get signal all the way back there(we likely need a second router).
Thanks all!

I use a Logitech webcam (midrange price). I have a 15ft USB connection, and it works super. I am told images degrade if the USB extension is too long, but I have used the 15ft and a 10ft extension together, with no image degrading. I run two cameras off one laptop, and it works great. Funny, my more powerful laptop doesn't run one as well as my old laptop runs two... go figure

p.s... I like to mount my webcams on tripods. Once fixed on the tripod, I can just adjust the tripods without having to tape a webcam somewhere and have it sit stationery.
