Tell me about it!! the motion ones would work at my mums as it'll mean it only goes off when someone walks up her drive etc but with ours cos Max lives outside and is always walking about it'll go off all the time anyway!!! So would probably just be best having it recording to a HD 7days a week. Gonna be sticking a big fuck off willow fence asap anyways and we were talking about fencing up the back half of the garden anyways so its for us and not the dogs.
