Cant view remote playback in iVMS 4500

Hi, I'm new here! I'm hoping someone can help me.

I'm having an issue with viewing remote playback on the iVMS 4500 app.

I have 1 camera (DS-2DE3304W-DE) and a PC with the server software running.

I can view the footage on another computer running the client software.

When I log in to the camera and check the Storage Management, nothing shows. Is this normal?

The iVMS app just says 'No record file.' This is also true if I try to view playback via browser.

Any ideas?
