When it's time to pair the keypad, the Ring app will have you create a four-digit PIN for arming and disarming the system. If you choose to have professional monitoring, you'll need to also come up with a verbal password to help identify you in case you have to talk to a dispatcher. As a reviewer — and a person who has tripped  countless alarms in the last few months — I also appreciate that there's a seven-day trial period before professional monitoring becomes active, so you can take time to set up the system without worrying about false alarms. It also gives you time to register the alarm so that you do not incur any fees.
The base station is also wall-mountable and can be installed on a Wi-Fi network or connected directly to your internet router over Ethernet. It has a 24-hour battery backup plus the ability to connect to an LTE network in the event of a power outage. (The LTE connectivity is available when you subscribe to Ring’s Protect Plus monitoring service and uses AT&T’s network.) Both the keypad and the base station feature colored LED rings to signify if the system is armed or disarmed and have built-in speakers to sound the alarm in the event of an emergency or intrusion.

I’m not certain about Nest, but I asked abode about this before. They said, “We have what is called abode Signal Guard. Unlike other smash and grab solutions, the Signal Guard works whether your system is self-monitored or professionally monitored. The abode Signal Guard alarm acts just like a normal alarm where notifications are sent and the siren(s) go off until the alarm is disabled. If you are a professionally monitored customer, the monitoring center is notified of the abode Signal Guard event.”
Ring's $199 Z-Wave-enabled Alarm Security Kit is so simple you might overlook it at first. The system includes a base station, a keypad, a door/window sensor, a motion sensor and a Z-Wave range extender. It's all basic hardware with basic functionality -- you won't find any fancy features here -- but the Security Kit is super simple to set up and monitor in the Ring mobile app. 
abode also sells their own line of cameras. They sell an image sensor, which will take three snapshots if it detects motion, and two streaming cameras. I’ve tested two of the three. The two cameras I tested were unfortunately unimpressive, and I found Nest cameras to be vastly superior. abode’s newest camera, not tested, offers two major benefits: FHD 1080P resolution and two-way audio. Of course, there’s also abode iota which offers the same camera specs as the newest abode streaming camera. The benefit of using abode cameras over Nest cameras is free cloud and local storage. abode’s streaming cameras support a microSD card and include three days of free cloud storage. Nest supplies just 3 hours of snapshot storage for free. As described above, if you want more Nest storage, you will need to pay for Nest Aware.

3) Operational Use. I like being able to set up polygons for the motion detection zones. I was able to easily mark my drive way, flowerbeds and porch. I’ve never had a problem with the busy traffic from the road (something the security guy mentioned was a problem with his original Ring). There are two problems they need to work out: You will get a motion detect when the night vision clicks on in the evening and when it clicks off in the morning. Expect that.
For doors especially, I much prefer sensors that can be embedded into the door and doorframe, so they’re completely hidden. As I mentioned earlier, Nest really innovated on this front, embedding pathway lights and secondary motion sensors into its Nest Detect sensors. Ring sensors have an LED that lights up when activated, and the base station (but not the keypad) will chirp when a sensor is activated, but that’s about it. But it’s worth noting that a basic Nest Secure system costs $499 to the Ring Alarm’s $199, and Nest Detect sensors cost $59 each where Ring’s cost just $20 (extra Ring motion sensors are priced at $30 each).
My Wi-Fi problems notwithstanding, both the doorbell and chime accessory were easy to pair with my wireless network. Just a word of caution: If you’re using a Wi-Fi range extender, make sure to pair the doorbell outside your house, right on your doorstep. This will ensure that Ring finds the extender, and not your router. If you pair the doorbell inside your home, you run the risk of pairing it with your main Wi-Fi router, especially if your router and range extender have different names.
One of the first things I did on the Pro was to draw the precise area I wanted the camera to monitor for motion. This process is done in the mobile app, using your finger, and allows you to highlight a sidewalk but ignore the street or an area where, perhaps, you have a wind chime hanging. As you can see above, I highlighted my entire entryway, sidewalk, and driveway. The street is eliminated completely.
     I've owned the Ring Video doorbell for about 6 months and it has been a very pleasant experience. It was very easy to install and easy to use. It has never stopped working or had any major issues. This doorbell lets me know when I get packages delivered, when people approach my door, or ring my doorbell. It is very convenient. The only issue I've had is with motion sensitivity. I get a ton of motion notifications from cars on the road, which are about 35 feet away from the doorbell. It seems very accurate with detecting people but it has an issues with cars, especially large vehicles.
