Starting over on remote viewer

Starting over on remote viewer

We have two issues going on at once.  We recently changed our NVR connection and are now running it through our Sonic Wall through a partitioned port, to allow access to the camera view from the smart phones of our managers.  They have requested that the process should be uncomplicated and easy. I have tried several options and in the process I have three apps with none of them allowing access to the camera feeds.  I have VMS client, CMS client, and NVMS7000 client currently loaded on this computer, so who ever helps m e can choose the proper app for our circumstances.  
On a separate issue,  our IP cameras are connected by two PoE switches (Net Gear) 54V  2.22A, 8 port . They are supporting 10 12V cameras.  Currently, both switches are in PoE mode, but there is one camera that is not powered.  I originally had just one switch as a PoE and had two cameras not powered.  When I made both switches PoE, I had hopes that all of the cameras would easily be powered.
