🚧 Work in progress / more details / code / features coming soon 🚧
40€ DIN-rail compatible WiFi security camera with additional features (doorbell detection, magnetic / reed switch door & PIR sensor...) that sends you alerts on Telegram if someone unauthorised breaks into your house.
Project is based on the Arduino framework (C++), with the PlatformIO Visual Studio Code add-on.
You either can flash the updates directly with a USB to TTL module, or directly upload updates over the air (OTA) using espota (already installed with PlatformIO).
Ensure you did the setup part by updating the src/secrets.h file and replacing WiFi SSID, password and Telegram API token with your values.
I wanted to keep it simple, hence it's using the well known AI-Thinker ESP32-CAM board. I'm using the 160° wide lens, so my entrancy / hallway can be seen in one sight.
The module is designed to be integrated into your electric panel, fixed on a standard DIN rail for direct wall mounting.
3D printed parts have been designed with OpenSCAD, which is an open-source software that helps create parts with just code. Easy to change, easy to share.
*.stl and *.scad files are stored under the /mechanical folder.
The module is powered thanks to a DIN-rail AC/DC 15W 5VDC converter, MeanWell HDR-15-5.
You might / need to add a circuit breaker, connected upstream of the 5V power supply (see note below)
The one I used is 16A / C-type curve, which is way overkill, since the
HDR-15-5only draws 250mA from main power (230V). However, due to its internal capacitors, this will reach 45A for a few dozen ms when powered up, hence my 16A circuit breaker. It'd be better to use a 2A model with a D-type curve - which I couldn't find here in my local store (refer to: https://www.meanwell.com/Upload/PDF/HDR-15/HDR-15-SPEC.PDF)
