The system may be in Learning Mode. If not, verify that the camera(s) are online by observing the front panel and/or connecting to the Processor and launching GRIDSMART Client. If the Site Card indicates one or more offline cameras, please troubleshoot offline cameras.
If the all cameras are online and the system is not learning, you might consider clearing calls on the zones. You might also consider restarting the Engine by clicking Diagnostics (stethoscope icon) on the Site Menu and clicking the Restart Engine button. If neither of these solutions work for you, please contact support.
