A 345Mhz version of the IQ Panel 4 is expected soon, but there is no ETA yet.
Currently the IQ Panel 2+ 345Mhz version is still available though it will be discontinued soon.
We recommend (and only sell) IQ Panels at this time. You can use any compatible panel with our service however, if you obtain a 2GIG Edge or if you wish to continue using the GC2.
There are no battery only camera options for Alarm.com.
