Derek,
Useful report, thanks. Techwin's back panel presentation is worse than the Sunnivision DVR, they should have come with a better, good looking DVR.Cameras have a lot better look than Sunnivision.
A few questions:
Is the DVR compatible with the SD DVRs client?
Is it compatible with the SmartViewer Client?
Is the eSATA port functional?

Re: using Internet Explorer only ... I've had success in using Google Chrome with the IE Tab Extension enabled to navigate different web servers from different manufacturers that force you to run Microsoft ActiveX OCX complements in order to see live video. Not sure if it will work on this particular Samsung AHD DVR though... now's your turn to try it :)

Thanks for the report!
Would be great to see the compairison with Hikvision TVI and Dahua CVI ??

Sounds like the intermittent rebooting when multiple cameras cut from day to night at the same instant is simply a the result of an undersized shared power supply not being able to meet the surge of all the cameras IR drawing power simultaneously without starving the DVR.
Easy enough to test just by putting the DVR on its own supply.
Of course this doesn't excuse Techwin in any way, but it may not be much of a practical concern for the majority of installs, since, IMHO, they would often be outside or in different rooms and so not be subject to 3 or 4 or them switching at the exact same instant.
