Qolsys Panel 4 and New Image Sensors

Hi all! I just upgraded from a Qolsys IQ Panel 2 to a Qolsys IQ Panel 4 and wanted to get some opinions on motion sensors, I don’t really want to spend a big chuck of change on new motion sensors since the panel 4 doesn’t support the ones I already have. What’s the thoughts on motion sensors these days? Are they still worth the money when I already have door, window, glass break sensors, and outdoor cameras?

If you are concerned primarily with the security system coverage, if you already have both window open/close sensors and glass break detectors covering all the windows, motion interior zones behave more as a redundancy.

A compatible model similar to Alarm.com image sensors is the PG9934P.
