[DW-VGA1G4] Inquiry Regarding Max Supported RTSP Streams and VMAX Performance in Spectrum

DW-VA1G4 1.0.12.24

Spectrum 5.1.5

Tech support is reporting video loss after a couple of days

RTSP streams and VMAX performance in Spectrum:

What is the maximum number of RTSP streams that can be supported within Spectrum for each model (16, 8, and 4 channels)?
Can VMAX A1 performance support all channels simultaneously without any performance issues?
Will other users be able to use C3 Cms, mobile, and/or web at the same time or will DVR have performance issues?

I will start my own test and confirm my results later next week.
