The one by the pool is a Panasonic BB-HCM371A wireless outdoor camera. It is the most feature rich webcam I have found. Both me and my dad has one. I also have a BL-C30 wireless indoor camera in my 20 month old son's room for the grandparents to see from abroad.

You can get more info about the poolcam here. I bought mine at www.provantage.com for $700. The indoor one is a lot cheaper for around $250.
