Hi ,i have just purchased a new G1WH ,i have bought this to detect thiefs.I have set it on Motion detect ,and wonder what would be the best settings .Should i use the loop timing or turn it off, ?Screen saver off or on ?Power saver off or on .Also what is the timer at the bottom of the screen.I know the top one is for total time left on card.I hope someone can help. Thankyou.
