The gray ones seem to have better video quality and they are 600 tvl my black ones are 700 and they are not quite as goodmight have to do with older gen dvr

This camera supports our older dvr and made things much clearer

Note whenever buying these type of cameras remember that most of them might say night vision is good to say 60 feet what it means it will see motion but the face will only be clear to about 40 feet
