I have 2 TC70 cameras, but they have different hardware and firmware versions. one is as above, the other is H/ware V3, F/ware V 1.1.22 The cameras both show as being up to date. Because of the differ

Should the C100 camera be left switched on 24/7 ? I have tried turning off and on, but it is taking a VERY long time to get a live view to show. Is it safe to leave on 24/7 ?
