First off let me say that the audio and video are crystal clear. But here is the reason for the 1 star... Amazon. For the first 30 days the system works flawlessly, and will record everything the doorbell and any cameras you have connected. But, once that 30 days are up your equipment is pretty much useless unless you pay Amazon to continue recording. You'll still get alerts but that's it. Yes, you have to trust Amazon, the company that uses Alexa to record people having sex. Nope.
