I got my new Ring security system yesterday and installed the panel, door sensor, and motion sensor yesterday. I have had a security system with a major national monitoring company for nearly six years. I am not new to this. I got the new Ring system to replace the current system I have due to the price of the monitoring. I like the idea of having $10 a month for all of my cameras and security system combined. By switching, I am able to save $55 a month by cancelling my previous monitoring from the companies that did so for my security system and cameras.
As of this writing, there are only a handful of add-on devices available that will work with the system, and for now, it doesn't support integrations with other Ring devices or third-party Z-Wave and Zigbee devices. That said, integration with Ring doorbells and cameras is on the way, and interoperability with third-party devices is also in the works.
UPDATE 16FEB2018: After two weeks, I must downgrade my review... it's become obvious that the Ring Floodlight Cam only detects motion during the day. At night, I can walk through the center of my defined motion zone, but the cam won't record until I'm within 10 feet of it. The defined zone is my driveway which is about 40 feet long and we have 3 cars. As long as the ne'er-do-wells only break into the car parked closest to the Ring cam, they will be recorded. A quick Google search for "ring cam won't detect motion at night" will yield many stories of the Ring product line failing to work in darkness. Apparently, the problem has been documented since September 2017 and Ring has failed to fix it. I must say that I'm beyond disappointed. At least I discovered this in enough time to send the cam back to Amazon for a refund.
