Fixed Issues

Bug Fixes

  • VIVOTEK cameras experienced the GetProfiles Error regardless of forcing ONVIF media1 or media2. Fixed.
  • The output from an Advantech ADAM-6060 I/O unit was not triggered by the event rule if it has never been placed on the grid after server restart. Fixed.
  • Hanwha PNM-9084x and PNM-90815x multi-sensor cameras are failing on ONVIF initialization requests from the server. Fixed.
  • Footage from the “Device recording” Event was missing frames for about one second when pre/post-recording is set. Fixed.
  • Analytic events did not work consistently. Fixed.
  • In laptops with dual GPUs, the desktop client will default to using the discrete GPU instead of the integrated GPU. Fixed.
  • The desktop client used a case-sensitive search when selecting a virtual camera folder to upload, which caused the action to fail with the error “No video files found in selected folder”. Fixed.


Software Improvements

  • New system setting and general improvements to HTTPS cameras:
    • Some cameras did not work in the HTTPS-only mode. Fixed.
    • Introduced a system-wide setting that forces HTTPS-only communication for cameras (System Administration àUse only HTTPS to connect to cameras”).  If this setting is enabled, the server will drop connections to cameras that do not support HTTPS or a supported proprietary API protocol.
  • System Owners will receive mobile push notifications by default for administrator-related events.

Analytics Improvements/Fixes

  • Added support for Dahua in-camera analytics to Loryta IPVS-B5442Ex.
