Upgrading my Open Source Pi Surveillance Server with Frigate The article describes the author's 2024 project of building a local, cloud-free Pi-based surveillance server using Frigate and a Coral TPU, housed in a rack-mounted Axzez Interceptor case. The author now aims to downsize the setup while retaining the use of affordable large hard drives and an AI accelerator for object detection. In 2024 I built a Pi Frigate NVR with Axzez's Interceptor 1U Case, and installed it in my 19" rack. Using a Coral TPU for object detection, it's been dutifully surveilling my property—on my terms 100% local, no cloud integration or account required . I've wanted to downsize the setup while keeping cheap large hard drives1, and an AI accelerator.
