✨This talk was recorded at ElixirConf EU in April 2024. If you're curious about our upcoming event, check https://elixirconf.eu ✨ The task was to replace a proprietary video recording platform with an elixir based solution that had to perform in some very harsh physical environment with unreliable power and bandwidth. Evercam chose to implement a Membrane based solution deployed using Nerves and leveraging Livebook and the emerging elixir machine learning & computer vision ecosystem. What we found was that it was relatively easy to put something together very quickly, but to actually make it work in production meant solving a lot of edge case problems. The resulting project, Ex_NVR has been made open source and is intended to be a kickstart for successful computer vision projects deployed on the edge
