# [[Front Door Cam]]

# Overview
This system incorporates many parts. The flow takes PIR sensor and then snaps a photo using N8N, Gemini to see if there is a human present. This photo is saved in NocoDB for future reference. If so it tells [[Home Assistant]] which alerts the home owner with light changes in living areas - blue/red and uses voice to inform house over snapcast of the presense at the front door. Voices can vary based on what Gemini sees.  A voice prompt is created and sent to the speaker asking for the user to press the button and state their purpose. The microphone records the response and returns it to be broadcast over the Snapcast system. We send a message to NTFY for an alert on phones that there is a human present. 


# TODO
- [ ] Add in laser tof to ensure human presense.
