Do you prefer the PG9975 or the PG9945 for the Qolsys IQ Panel 2+? I will be using them on the entry doors to my home. I’m not worried about the esthetics, I just want the one that works the best as a PowerG sensor.
The chief difference in this case is aesthetics. The PG9945 has a wired input which allows you to use it as a transmitter for a wired sensor. If that functionality is not needed, the choice would mostly boil down to cost/looks.
