### 1/5 — Ugh

*2021-09-05, version 5.11.19*

Why can’t I be logged in on multiple devices? Why is the notification so missable? Why is my apartment building so cheap?

### 1/5 — Useless app. Does not work.

*2019-06-25, version 1.1.15*

Upon registering and open an app get repeated errors a push notification problem. Nowhere allows you to set serial number of a camera. Also splash screen saying you must pay expiration of service. Do not download waste of time

### 5/5 — Great!

*2019-06-01*

Convenient, easy, professional!
