Install
Choose the package for your operating system and processor on Downloads. Windows uses the setup EXE, macOS the PKG or DMG, and Linux the DEB, RPM or archive. Linux needs GTK4 and WebKitGTK 6.0. These initial builds retain the existing unsigned publisher status; only download from this website and verify the supplied checksums.
Open a local file
Click Open database and choose Local file. Browse to your Nx Witness SQLite database or supported backup. Free mode shows the camera inventory with passwords hidden; the original file is read only.
Activate Pro
Create and verify your website account. Buy a lifetime Pro licence on the Free & Pro page, which shows the current price and purchase availability. Then open Account & licence in the app and sign in with your email and password. If enabled, enter your authenticator code. Name the device and activate it. Pro unlocks without reinstalling.
Connect to Nx Witness
With Pro, choose Nearby server or Nx Cloud from Open database. For a local server, discover it or enter an HTTPS address. Review any certificate fingerprint before trusting it. Sign in with local or Nx Cloud credentials that have site backup administrator rights. A shared Power User account cannot request a backup.
The backup is opened in memory. Close database releases it; Save backup as explicitly writes a copy. Backups up to 128 MiB are supported. Camera data and Nx credentials never go to this licensing website.
Manage your devices
Your account lists five active devices. Remove a lost or retired machine before activating its replacement. After initial setup, five replacements are included per rolling 30 days. Existing offline access can continue for up to seven days after removal.
Updates
Open About & updates to check this website for a new version. Download the matching package, then choose Install and close. The app verifies the signed release information and package checksum before installation.
Command line
The CLI is available to Pro customers. Run nx-camera-info auth login to sign in, nx-camera-info auth status to see the licence, and nx-camera-info --help for report options.
