PREREQUISITES: GRIDSMART Processors must first be updated to 21.3 or later. 

CRITICAL NOTE ABOUT THE UPDATE: This update will take less than 10 minutes to complete. It includes both low-level firmware updates as well as security updates to the underlying operating system. Upon reboot, it may take several minutes for the system to start up while the operating system updates are applied, with both the STATUS and CAMSTAT LEDs flashing during this time.


When the update is complete, it will be indicated in two ways:

  • The phase LEDs on the front of the processor will all turn green.
  • The Web App displays a progress bar during the update that will show that the update has completed and the system is rebooting.

NEW: Support for the next generation GRIDSMART Processor, the GS3. The most powerful compute platform to ever be used at scale in a traffic cabinet.

NEW: Adds support for Pedestrian Crosswalk Zones for pedestrian all-clear and pedestrian counting in single-camera installations. Users must be cognizant of safety implications related to potential occlusion when using a single camera for pedestrian functionality.

IMPROVEMENT: Improves vehicle detection in left-turn zones, particularly zones with shadows or at times of dawn and dusk.

FIX: GRIDSMART now supports the full range of ITS detector inputs. This fixes an issue where detectors calls were incorrectly mapped for ITS and ATC cabinets. GRIDSMART Detector inputs 1-24, SIU Inputs 6-29, are now available on all 5 input SIUs 9-13.

FIX: Resolves an issue where images and data continue to be logged to external USB hard drives after a user disables USB Devices using the Web App.

FIX: Resolves an issue in the App that caused site configuration (AGS) files from versions 21.3 and 21.3.1 to either be partially imported or fail to import entirely.

FIX: Resolves an issue in the App that prevented camera stream URLs from displaying in the Site Info view.

FIX: Resolves an issue that prevented the Flash Alert (Loss of Greens) from being sent.

FIX: Resolves an issue where camera Day and Night mode transitions were not logged, causing the Camera Uptime chart on GRIDSMART. cloud to be inaccurate.

FIX: Resolves an issue where the “Reset Streams” function in the Web App did not complete a full reset.
