The Base Station keeps your Alarm system online and connected to your mobile devices. It connects to your home network via ethernet or wi-fi and links to all your Alarm components and select third-party devices via Z-Wave. Also included are a built-in 110-decibel siren, 24-hour backup battery and optional cellular backup (with a Ring Protect Plus subscription).
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.
