Thanks, Yeah the 3mp takes it up towards £400 with the 2.1mp is about £250 could you give me a good comparison for what the difference in quality would be please? I'm thinking it's similar to a front facing smart phone camera at a few ft? I've no cctv experience but get asked to do stuff like this for friends who are technophobes, so I need them to understand the difference in the choice before they can decide
