Would adding a motion detector plus the Firefighter get me a burglar and fire certificate for central monitoring? and is that monitoring presently $19 per month?
Yes
What is the $5 per month listed with the IQ4 hub?
All plans can be professionally monitored or optionally self monitored. Professional monitoring is $5.
So, if you want the Alarm plan, it would be $14 self monitored or $19 for professional operator monitoring.
