When you say “full coverage” I’m assuming you mean continuous recording, is that right? Arlo and Nest can record continuously, but only if they are plugged in. Also, the outdoor power cord for Arlo is new and it’s on a pretty long lead time right now. It’s sold separately from the camera. If you could confirm that your new is continuous recording, I’ll dig in a little more, but I don’t want to assume anything before making a recommendation.
If you do have smart lights and want to control them with a contact sensor or motion detector, you will need to install separate ones in addition to Ring’s, which can make your front door look like it’s grown barnacles with all of the sensors installed. Another simple integration would be to set a smart thermostat to its away mode when the Alarm is set to away, and then switch it back to its home mode when the Alarm is disarmed, but that’s currently not possible either.
As far as Ring Alarm, I don’t have an answer for you, but I understand and appreciate the knowledge you’ve shared. I would also agree that if they haven’t advertised jamming detection, that’s probably because it doesn’t exist. A Twitter friend of mine, who works for Underwriters Laboratories (UL), also mentioned that the system is not UL certified. Again, probably not as important to you as this jamming issue, but something interesting to note.

Rose first let me say thanks for the reviews. But just wanted to let you know (and maybe the nest guy you talked with also) that you can choose to only get notifications for people and not motion. This has been available for at least 3 months now. Also have only had one time when it had reported a person and was not. Car lights was what it really saw.
When you add the keypad, you’re asked to come up with a four-digit PIN that you’ll use to arm and disarm the system. If you opt in to professional monitoring, you’ll also need to come up with a verbal passcode that you’ll use to identify yourself as an authorized user when the monitoring service calls (so be sure to provide this information to your secondary contact, as they’ll need it as well).

 We installed two new Floodlight Cams, one over the garage, and one in the backyard. Easy installation into existing Floodlight box. After installation, we had a problem connecting. We just call up support and they walk us through it within minutes. Great compliment to our Ring Video Doorbell Pro. We love it so much, our daughter got one, and we monitor their house too.
