Hi it's to set the individual camera settings menu for day/night settings zoom, etc, It is a bit fiddly if you are not in the same room as you have to keep going back to the TV screen to seen if it is set up correctly though
Hello Mr L,
I am not sure if I can offer you a difinitive answer about these cameras as I installed these just 2 months or so ago. I have fitted them to some of the facia boards but they are sheilded from direct weather exposure as they are under the rain guttering. However, the quality and clarity of the feeds are quite good for a medium priced cc-tv system.
