hiya, trying to do a friend a favour, i need a decent cctv camera that has night vision, its going to be in a bacj garden looking down the side of the house, so more than likely be a out side light on most of the time, nothing special just a outside light with a energy saving light bulb init, i would say needs to be a 20 meter night vision one, he wants it to be pretty good and be able to make faces out on it, not sure if this can be doen for his price range which is around 150 pounds, if its possible cheaper then that be ok to lol, better if it can be colour, anyone got any reccomendations ? thanks
