Help me build my system

What is the benefit of using alarm.com supported cameras vs Nest/Ring cameras? Is Alarm.com monitoring my video feed?

It does open up options for video verification and AI deterrence through Alarm.com. Video verification is an option on our Protect and Complete plan which you can set up to allow professional monitoring operators to check your camera feeds during an alarm event to verify whether it is a true break in. Many jurisdictsions are adopting verification requirements prior to dispatching police. Using Alarm.com cameras integrates your video surveillance with your alarm system controls, so all of your security is in one app. You can create recording rules using Alarm.com AI analytics, and rules based on alarm system activity.

Also, you mentioned motion sensors to cover areas with a lot of windows vs window sensor. At night when the “Stay” alarm is set, will the motion sensors operate?

When you arm Stay, motion detectors are not armed. You can instead use Night arming mode on IQ Panel 4 firmware 4.4.1+ to arm all zones except motion detectors designated as night zones. This lets you arm some motion detectors, but not all of them, if there are some you may activate in the middle of the night.

To use Night mode arming you would need a Night mode zone type programmed for one of your motion detectors.

Night zones will be bypassed in night arming, but other Interior Followers will be enabled.

For motion detectors you want to have added as Night zones, that sensor’s programming would just need to have Sensor group 21 selected.
