What is a remote monitoring app?

It's the phone (or desktop) app that lets you see and control your security devices from anywhere. Through it you get live video from your cameras and doorbell, review recorded clips, receive motion and alarm notifications, talk through two-way audio, and often arm or disarm an alarm or share access with family. Every camera, doorbell and alarm relies on one — a great camera is only as useful as the app you check it on — so choosing the right app is a real part of setting up home security, not an afterthought.
