To use the Power G Image Sensor you’ll want to make sure you have 2.3 firmware on your IQ Panel 2. See the firmware release notes here.
“Improved integration with the PowerG PIR CAM (PG9934P or PG9944) so that the Panel now captures 10
images from the PIR CAM during an alarm event and stitches them together into a video that is stored locally on the panel. 1 static Alarm Photo from the PIR CAM is also sent to Alarm.com”
Images and Video can be found by swiping left to the additional screens from your home page.
