1. Does the 3.3.4 come with virtual host?
I don't actually know, sorry, as I'm running it on a 7816N-E2 that has no PoE ports. I'm leaving my 7816N-E2/8P pretty much alone in terms of updates as its my 'production system'.
2. How are you finding it with respect to software bugs etc.
I haven't seen any quirks or problems on the web GUI, it's stable and been on it about 2 weeks just to see how it is.
It would have been good to have motion events highlighted with continuous recording on the playback timeline on the web GUI. But it does have that on the VGA/HDMI interface, which I don't use much.
One thing I have noticed on the VGA/HDMI interface is that mouse clicks are now quite erratic, often giving multiples, quite annoying when entering the required long strong password.
3. Does the motion email attached photos of the motion event?
Until I take the time to tune down the motion events in the cameras, I won't be using email alerts as I'd be swamped.
But I should do some experiments with that as it seems to be a problem topic on the newer firmware.
