Introducing Nx Witness™ v2.3.

The latest version of Nx Witness is v2.3.2.


Server Hive Architecture. No Single Point-of-Failure. 
Automatic Failover. One-Click Upgrades. And More.

With a radical new server-hive architecture Nx Witness v2.3 redefines what it means to combine simplicity of use with advanced features.

Check out all the new features below - then upgrade your existing system or try Nx Witness FREE today.


NO SINGLE POINT OF FAILURE. 
(SERVER HIVE ARCHITECTURE)

With version 2.3 all servers in a system are now part of a Server Hive and continuously synchronize system configuration settings. This allows operators to connect to any server at any time to view the entire system. This, in turn, creates a system capable of adapting to server failures in real-time and ensures no single point of failure in multi-server systems.


AUTOMATIC CAMERA FAILOVER.

With v2.3's Server Hive architecture comes automatic camera failover. In case of server failure the cameras will be immediately transferred to other system servers. Servers must be enabled as failover servers, and users can define maximum camera capacity of failover servers.  If a failed server once gain becomes available, cameras will return to their original server.


ONE-CLICK SYSTEM-WIDE UPGRADES.

With version 2.3 system administrators can now upgrade an entire system (all servers and clients in a system, regardless of operating system or device type) to a newer version or to a specific build from any client connected to the system. If the system does not have Internet access, users are provided a link which will download a system-specific update package in .zip format - which can then be installed from any Client connected to the system.


VIDEO WALL / REMOTE MONITOR.

In v2.3 we introduce another flexible, mind-blowing feature - Video Wall / Remote Monitor. This feature allows a single user or multiple users to control an unlimited number of video wall/remote monitors in real-time from any Nx Witness client. Video Wall is a licensed feature - with each license adding 1 user and 2 screens. So, for example, if a system has 20 video wall/remote the system would need 10 video wall licenses. 


EMBEDDED SDK + API = ABSOLUTELY OPEN.

We want our users to be able to use Nx Witness in any way they can conceive of - and so we're introducing an open, documented API and SDK directly into the Nx Witness Server package. That's right - whenever you install Nx Witness server you also get access to our API and SDK. No strings attached. No registrations. Just total access.

With the Nx Witness Server API developers can fully integrate Nx Witness into 3rd party systems such Access Control, Video Content Analysis, Point-of-Sale solutions and more.

The Video Source SDK allows integrators, end-users and tech partners the ability to integrate video streams from early any source - including cameras, 3rd party DVRs & NVR's or even cloud-based storage.


Additional New Features.

Edge (aka ARM device support).
In version 2.3 the system Server can now be installed and run on virtually any ARM® device. This allows Nx Witness's full Server application to run on cameras, microcomputers, embedded devices, and more. Edge is a licensed feature and is available only to manufacturer partners of Network Optix. Have an Edge application for Nx Witness you'd like to discuss? Email us.

 

Universal Fisheye Dewarping.
Nx Witness now supports fisheye dewarping on any type of fisheye lens - including panamorph lenses. Users can automatically or manually configure dewarping under the camera settings dialog.


Max/Min Recording Time per Camera.
Version 2.3 gives users the ability to specify the minimum and maximum amount of days footage will be archived from each camera. Max/Min settings can be applied to individual or multiple cameras. For example, in a single system one camera could be set to record for a maximum time of 30 days, and another for a minimum of 7 days.


Web-Based Camera Settings.
Version 2.3 now includes the ability to view the camera's native web page inside the camera settings dialog. This feature is available currently for a few camera models and works over both LAN and WAN connections. The feature only applies to select cameras in the 2.3 release but can be extended to additional models. Have a camera you'd like to add this feature for?  Email Us.

 

Web Admin Redesign.
In version 2.3 there is an all-new web administration client that gives users the ability to monitor server health and storage configuration, remotely restart servers, merge or split systems, or modify System ID, port, login and password. The web monitoring client has been temporarily removed while it undergoes a full redesign for enhanced usability and will be available again in v2.4 in mid-2015.

 

 

Simplified System Expansion (aka joining systems).
Servers/system can now be managed (merged or split) with just a few clicks by a system administrator in the system client or web administration interface. 

 

 

 

One Network Port For Everything.
With version 2.3 network traffic is now directed through a single port (7001) on each server, making port forwarding much simpler.

 

 


Advanced Routing Management.
Network setup between servers is now simpler and more flexible. While the system automatically detects and configures network routing upon setup we have added the option (for advanced network configurations) to assign specific IP addresses that can be used for accessing servers (e.g. public/internal IP addresses, domain names etc) in an all-new advanced routing management dialog.

 

 

System and Local Settings Dialog Improvement.
System settings and Local settings have been reorganized into separate dialogs to simplify setup and provide a faster, cleaner, and more logical user experience when modifying configurations.

 

 


Smarter Time Synchronization.
With version 2.3 Time Synchronization is simpler and more powerful than ever. For systems with active Internet connection the system will automatically synchronize time with a selection of public NTP servers. For systems without Internet connections users can choose a local system server to serve as the time-server.

 

 

Client Customization.
In version 2.3 users can now customize their client to their liking with the ability to change background animation color, disable background animation completely, or even assign an image as background.


Improvements.

  • More flexible camera reassignment. Cameras can now be dragged to a new server even when they are offline or undiscovered.
  • Main Menu and Context Menu have been reorganized and simplified..
  • Preview Search has been simplified by adding a right-click drill-down feature on a time slice.
  • Servers that need to be updated to match the latest version installed in the system are now shown in red in the about menu.
  • Smarter mouse zoom behavior while viewing multiple videos on the grid.
  • E-Mail notifications now have customizable templates.
  • ESC hot-key behavior has been changed. To toggle full screen use Alt+Enter. To close dialogs or cancel actions, use ESC.
