Is Your Camera Spying on You? ROOT Observer Offers a Secure Alternative

Always feel like somebody's watchin' you? No, it’s not a dream — it’s your security camera. With all of the data breaches that are reported on a regular basis, few people feel like they can really trust a cloud-based service with their most private data these days. However, having a system of home security cameras gives people a lot of peace of mind when they are away. This convenience often wins out over privacy concerns, and we just hope for the best.

The ROOT Observer is an open source security camera that is trying to eliminate this trade-off. Everything from the hardware design to the source code is freely available for anyone to inspect so that we can be sure there is no funny business going on. ROOT even provides a step-by-step guide to aid in building your own Observer.

Instead of relying on a company-controlled cloud platform, the ROOT Observer is designed around a “local-first” architecture. Video recordings are stored directly on the device itself rather than on a remote server. The camera runs on a small, inexpensive single-board computer — a Raspberry Pi Zero 2 W — paired with a compatible camera module and a microSD card for storage. Optional accessories like a USB microphone and a small buzzer can add audio recording and audible alerts.

Getting the hardware running is very straightforward. Users begin by downloading the ROOT firmware image and flashing it to a microSD card using standard tools such as Raspberry Pi Imager. Once the card is inserted into the Pi and the camera module is connected, the device can be powered on and configured through the ROOT Connect web interface.

While many open source camera systems focus on local network video recording setups, ROOT includes a relay server designed to allow secure remote access without exposing raw video data. The relay server functions as a middleman that passes encrypted messages between the camera and the user’s device, but it cannot decrypt or view the content itself.

To accomplish this, ROOT implements end-to-end encryption and forward secrecy. These techniques ensure that video streams, recordings, and alerts remain unreadable to anyone except the authorized user — even the relay server operator. Users can run their own relay server to avoid relying on a public instance, making the system entirely self-hosted if desired.

The camera also performs on-device machine learning for event detection. Instead of sending video clips to the cloud for analysis, the device itself can identify events such as people, pets, or vehicles. This allows the system to generate encrypted push notifications while keeping all image processing local.

According to the developer, the firmware is heavily optimized so that the Raspberry Pi Zero 2 W can handle video streaming, recording, AI detection, and file transfers simultaneously without exceeding roughly 60% CPU usage. This efficiency allows the tiny computer to act as a full-featured standalone security camera.

The ROOT Observer is currently in the prototype stage, with early units housed in 3D-printed enclosures. Pre-production models are expected to be sent to testers soon, while the open source firmware is already available for anyone interested in building their own privacy-first security camera today.
