You can get a number of wifi cameras at Argos. I bought a sony action cam from there which has had some serious mistreatment, it's a very tough camera. they also have a vivitar action cam which is a lot cheaper. As long as it has WiFi and a waterproof case you can't go wrong. (And a smartphone)
Thank you for reply smurf. I'm using the guttervac this Saturday for first time. Can you get what you talking about in Argos? Thanks againStephen
