hi,
me again... small update...all 7 of my cams still working fine (since 08.2013), no problems in terms of reliability yet
the one with 64gb msdxc card also working fine, no corruption of card or such....
i saw three questions in posts which i might be able to answer:
if you want to use a different usb power adapter to provide power to g1w you should have one that provides 2A, dont forget that when it says it gives 2A power in reality most of time it provides up to 30% less...so using a 1A adapter for example actually will give only 700ma and that will be not enough, it needs more. you can check and see that the original power adapter of g1w provides more than 1A
next question was about how much time you can record, a 32gb msdhc card provides capacity for 4,5 hours recording for full hd....just divide that values corresponding, so for 8gb it would be: 8gb= 32/4 -> 4,5/4=1,1h
another question was about crash, well i have no crash expirience with it, but there is a shock sensor in the cam, you can even adjust its sensitivity in the settings...and theoreticallly if it detects collision it should record protect that video so it wont be overwritten...needs to experiment and check how reliable that actually works...but it is there
about long term working of the g1w, i had one cam working for several weeks without pause inside a room without turning it off, there were no problems, worked fine!
