Amazon positions its Alexa Guard Service as a "smart home security system" and says it can help you "keep your home safe".
However, the service—dependent on hardwired (no built-in battery backup) Echo devices with just IP communications—no alternative like cellular or a phone line—presents a risk to end users in the event of a power outage.
In this note, we examine:
- How Echos have no built-in battery backup
- How Echos only communicate via WiFi
- How Alexa Guard is branded as a free security service
- How security systems typically have power and communications redundancy
- How Alexa Guard can lead to a false sense of security for DIY end users
- How ADT uses Alexa Guard as part of its monitoring platform
- Response from Amazon
- How Alexa Guard failures will be common
