to be honnest, 1.3MP 720P is largest OK, in fact when someone ring is about 50cm - 1m , so you have an impressive quality, by the way the VTH1550 is 800X600 so not need more :lol::winktongue:
in my mind if it not reply to ping you dont have possibility to reboot.
in fact recovery tftp doesnt work with VTO, you must dont loose your time and return to your seller
