Well I tried it - and it was rubbish! The camera flopped about in the bag, which was much too light and blew about in even mild breezes and the bag material itself rustled like crazy ruining any attempt to record audio through the on-camera mic.
There was obviously room for improvement, and the "Bag cam" as it stood was not fit for purpose, so I had a think, came up with an idea, grabbed some everyday household stuff and created a new improved "Doggie Cam"
It's easy to make, effective and solves most of the problems presented by the unsuccessful "Bag Cam". Check out how to make one yourself in the video below. It's great fun and won't cost you anything.
