Manual does not say a word about video ports (but actually I received a generic manual for this DVR family rather than its own).
Router is sitecom 54g, and this is my port forwarding (attached).
But ShieldsUp! says my 640xx ports are closed! Why?!?
I found several DVR viewers, but none works for me:

By the way, what are "Video Server E" and "Video Server S", talking about DVR streaming?
My DVR-8204 supports up to 4 alarm sensor, but how to connect them?

I tried just connecting a switch mamong pin 1 and GND and closing the switch, but nothing happens both if pin is set to high or low in configuration.
