Heimdall
Turn any device into a security camera. No app needed.
What it does
Heimdall turns any device with a browser and camera into a security camera — no downloads, no app stores, no hardware to buy. Just open a URL, and your old smartphone, tablet, or laptop becomes part of your security grid. Streams are encrypted p2p (your video never touches our servers), and you get instant motion alerts when something moves. It also works as a travel baby monitor — forgot yours on holiday? Open Heimdall on a spare phone and get sound/motion alerts while your little one sleeps.

I wrote some blog posts about the process: PCB design: https://toaster.llc/blog/pcb Enclosure design: https://toaster.llc/blog/enclosure Image pipeline:…

I needed a security camera inside my house, one that would send motion notifications to my smartphone and would allow me to livestream remotely. However, I could not find one that I could trust due to privacy concerns. Many of them upload the plaintext of videos to their servers and none is fully open-source as far as I know. Therefore, I decided to use my spare time to build one from scratch. Called Privastead (as in Private Homestead), it uses OpenMLS for end-to-end encryption (between the camera local hub and the smartphone) and is mostly implemented in Rust (except for part of the…
