I have five dogs and at least one of em has realised that if they can't be arsed to go up the garden for a crap when the back door is open, they can just do it indoors by the back door and they'll get away with it cos I don't know which one dunnit and I won't smack an innocent dog so they laugh at me. Or at least the one that's doing it is.
So what's the best budget motion (see what I did there :)) detecting go pro thingy out there guys?
