Product Questions
How do I remotely view the Avalonix Premium Series DVR or NVR via iphone, ipad, android phone or tablet, laptop, etc?
Question by: Sanders on Apr 21, 2026, 5:15 PM
You can remotely view an Avalonix Premium Series DVR or NVR from an iPhone, iPad, Android phone, Windows PC, or Mac as long as the DVR is connected to the internet through your router.
For mobile remote viewing, including iPhone and iPad, please see this guide:
https://www.cctvcameraworld.com/dummies-guide-watching-security-camera-system-internet/
For Windows PC and Mac remote viewing software, please see this guide:
https://www.cctvcameraworld.com/cmsoftware/
In general, remote viewing works by connecting the DVR to your network, then using the free mobile app or computer software to scan the DVR’s QR code or add the system. Once set up, you can watch live video, play back recorded footage, and receive alerts remotely.
If you are using an Avalonix Premium Series DVR or NVR with compatible cameras, internet is optional for local recording, but it is required for remote viewing away from the property.

Does the unit allow for multiple logins from remote PC's to monitor the cameras?
Does the unit have the concept of different user accounts for monitoring and administration tasks?
Does the unit have the concept of different user accounts for monitoring and administration tasks?
Question by: Alan Brown on Feb 23, 2026, 10:49 AM
Yes, all Avalonix Premium Series recorders allow multiple remote logins using our free smartphone app as well as our Windows and Mac viewing software.
You can create multiple user accounts with different permission levels. The system supports both administrator and standard user roles, and you can assign access at a granular level per camera channel. For example, you can create a user account that only has live view and/or playback rights for specific cameras while restricting access to system settings.
The number of users who can log in simultaneously depends on your available network and internet bandwidth, as well as the number of camera streams and their resolution being viewed.
When viewing multiple cameras in grid view, the software automatically uses the sub-stream to reduce bandwidth usage. When a single camera is viewed full screen, it switches to the main stream for full-resolution viewing. The main stream is the camera’s full recording resolution, while the sub-stream is a lower-resolution stream (typically around 480P) used for efficient remote monitoring.
