Seems like your using techpross for your app. If this is the case, your using the wrong app. The Prime series DVR's/NVR's use a different app called Guardian Expert. 

That explains why your trying to use 37777 like you normally would on our Elite series recorders, however the Prime series uses that new app and port 8000.

Please call (866) 573-8878 Ext. 3 with your order# handy for additional help on this matter if you need it. Thanks. 

I apologize for replying to an old thread...but I am lost here.

I am also getting "Starting live view..." and then "[Error code: 413]"

I can playback without an issue. So, I guess I am correct with all port forwarding settings. I can also log in using browser so my username and password are correct.

I was wondering if anc6802 found a solution to the error code? I am assuming this error is related to updated Guarding Express app and not my settings.

Thank you in advance.

Jose Malave,

At first, I thought it was odd that I have to open port 80. Because, in the past I only had to open port 8000. After setting 80, 8000 and 554 forward my Guarding Expert app worked with live view. So thank you so much!

As a test, I closed port 80 and it still worked. So I guess RTSP port was the one that allowed live view. Which is strange because in the past I did not have to configure this port for Guarding Expert app to work...

Well, my problem is solved. Thank you Jose. Now, only thing I have to worry about is to pass PCI Compliance with these two open ports.
