Don't what to tell you on the cameras. I have the Ring Alarm and use this integration. It’s excellent and covers my personal requirement of having the alarm system independent of my Home Automation hub, and yet integrated so I can utilize the sensors for triggering events on the hub and using the keypad to control other devices on the hub, as well as arming and disarming the alarm system with my door lock and presences, and arming the whole lot with Alexa or the press of a Pico button.
Ring’s no-contract monitoring fee is very low, and the alarm hub itself offers free cellular backup. Also has an excellent Z-Wave 700 500 series implementation that so far has been very stable and fast.
