When you arm or disarm the system, the keypad and the base station play a female voice that informs you of the system’s status (the keypad’s speaker is unfortunately subdued). LEDs on both devices provide visual feedback as well, although only the base station gives you a constant visual cue as to the system’s status: Blue for unarmed, red for armed.
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.
The doorbell can be used in temperatures as low as -5°F and as high as 120°F, enabling operation in a wide variety of environments. Additionally, the package comes with four different colored faceplates (black, charcoal, silver, and white) so that you can match the doorbell to your home's exterior or your existing hardware. Motion detection with programmable zones will send an alert to your smartphone or tablet when movement is detected in one of the motion zones, and bank-grade encryption offers safe transfer of data from the doorbell to your mobile device.
2 - This kind of goes along with #2. You cannot access the doorbell with security software like Blue Iris,et.al. Now, I get that they want to sell you their Cloud service and I'm ok with $30 / year to have an off-site backup. But if you could link the doorbell into your security system you would have an actual video of everything in your possession and you could access it from any computer in the world. That would be REALLY handy for police investigations and any legal hassles that may come your way.
