On my IE9, Windows 7, laptop, I could not get my Zmodo system to stream the video over the network or internet. I have four other machines, all IE8 and XP that worked perfectly.
I tried all the many suggested fixes, Activex permissions, ocx updates, low security settings, etc. I was using the viewer that came with the H9104 package. I could not get it to cooperate. All I got was the camera grids with no video. Oddly enough occasionally it WOULD work and I thought I had it fixed. Next time - nothing.
I finally discovered that another viewer was on the install disc that came with the 9104 package. It is Netviewer_ENU_V2.1.584.0.exe. It is found online, but I didn't try to download it from there. If you can't find it, let me know here and I'll try to email a copy to you.
It worked for me.
