Backyard Pool Surveillance?

We've mentioned the benefits of pool alarms before for swimming pool owners, but that doesn't solve the question of how to keep on eye on the kids while they are in the pool (and you don't want to be).  A short article from http://www.backyardagora.com called Why Video Surveillance Cameras for the Backyard Swimming Pool Make Sense goes into the reasons why cameras in the backyard and around the pool are a good idea not only from a security standpoint but from a watching-your-kids-to-make-sure-they're-being-safe standpoint.
