1- I want to have TWO accounts namely, admin (with all the rights n features) and a user account (only for viewing , no options for zooming etc)
The
mydlink service works by first creating
one account and then registering all Cloud cameras with the new account. The one account will have the ability to view live video feeds from all four cameras. Unfortunately, this account will also have admin access to registered cameras. There is no guest account concept implemented with "read only" access using the mydlink service.
That said, the DCS-930L hardware itself supports multiple accounts. The admin account can access all configuration pages in the camera firmware web UI. Additional user accounts can only view the LIVE VIDEO page of the web UI. If the camera IP address is entered into a browser, the admin account can see live video feed and configuration pages, while the other user accounts can only see the live video feed.
Just to be clear, the separate "user accounts" created through the camera web UI are only used for direct camera access through IP.
2- I have read that through D-VIEWcam, "admin account" can see the views from multiple cameras on one screen...but if there is a provision of creating user account, will the user account be able to see the view from all the four cameras on one screen of pc/android/iphone?
I think you are mixing applications here. D-ViewCam is a free D-Link desktop application that must be installed on and run from a host PC. The application records video feeds for playback and provides a form of remote connectivity.
D-Link now offers a relatively new mobile app available for D-ViewCam, but I have yet to try it personally. I can say that the D-ViewCam mobile app is dependent on the D-ViewCam desktop application running on a dedicated PC on the same LAN as the other cameras, which would mean you would need a PC running at all times to support the four cameras using this approach. I'm not sure if the mobile app is compatible with the free version of D-ViewCam, I believe it may only work with some higher tiered version.
The mobile D-ViewCam app is also compatible with D-Link's NVR, which is a dedicated device with two HDDs that could record the video feeds from all connected cameras for archival and playback. Remote access can be configured to this device with tiered permissions that can go so far as to give specific users view-only access to specific cameras, while excluding others.
The typical mobile apps that you've probably read about work through the mydlink service described on my previous answer above. Through the mydlink service, the
mydlink Lite smartphone app (android/iPhone) can only view one live video feed on the screen at a time. The
mydlink+ tablet app (android/iPad) app can view four live feeds at the same time. Since there is only one account (admin) supporting all cameras, there is no distinction between "admin" and "user account".
