CameraStack ONVIF & RTSP Server now supports the Rockchip RV1126B chipset. Adding new chipsets to CameraStack is now just a thin layer of vendor-specific code that automatically benefits from a large, full-featured portable core. camerastack.io/blog/cameras...

We've made a couple of free tools for managing camera TLS certificates over standard ONVIF. A full-featured desktop app called CameraStack TLS Manager, and a simpler script if all you need is self-signed certificates. camerastack.io/tools/
CameraStack TLS Manager on Linux, showing a camera's keys, certificates and certification paths alongside live HTTPS state for a self-signed identity.

New chipset supported by CameraStack Server: Rockchip RV1106. The portable ONVIF & RTSP core makes it easy to bring up new chipsets, with a small Rockchip plugin handling the chipset-specific video pipeline. camerastack.io/server/rv1106/

Object analytics is live in CameraStack's ONVIF & RTSP server: selectable object detection models on NVIDIA Jetson, Sophgo SG2002, Axera AX630C and Rockchip RV1106, publishing tracked objects as standard ONVIF metadata that any viewer can overlay. camerastack.io/blog/object-...

We've added support for ONVIF MotionRegionDetector motion analytics on all platforms supported by CameraStack. Uses minimal CPU and, like all of our other features, works portably & optimally across disparate chipsets and vendor SDKs: camerastack.io/blog/onvif-m...

As promised, the next camera chipset getting the CameraStack treatment is the SG2002, a mini RISC-V camera SoC from Sophgo. We added ONVIF PTZ support for this one, plus new vendor plugin capabilities like on-demand keyframes, live encoder reconfiguration, OSD and JPEG snapshots.

Building on the years we've spent developing camera firmware across many chipsets, we've made a highly portable camera stack that uses small SoC-specific adapters together with a feature-rich shared core, bringing all the ONVIF & RTSP goodness to any SoC.

Our camera software stack is coming along nicely: passes all of 266 tests in the ONVIF Test Tool for Profile S & Profile T.

Our patch has landed in GStreamer Analytics: adds support for IOU tracking to ONVIF Analytics Metadata streams. We're using this in our ONVIF Analytics Viewer so it's great to see it upstreamed. gitlab.freedesktop.org/gstreamer/gs...

On a mission to get our cross-platforn ONVIF & RTSP camera stack running on as many chipsets as possible. Latest SoC: Axera AX630C. We've replaced the vendor firmware on a cheap camera with our own portable stack. That's Jetson, Raspberry Pi and AX630C done. Sophgo SG2002 next.

Our AI-enriched Restreamer: Takes any dumb camera feed, runs YOLO on an RK3588 NPU, restreams as RTSP enriched with ONVIF analytics metadata. Custom GStreamer elements for zero-copy decode, inference & metadata injection. Multi-camera & platform-independent (not just RK3588).

Took a day off from staring at screens to smell the roses at Chelsea Flower Show. Somehow still ended up nerding out over YOLO and multispectral cameras being used to monitor plant health 🌹📷

On the bench this week: We've been building an NVR using the Rockchip RK3588. It's packed with hardware codecs, NPU and GPU acceleration, a great foundation for an NVR with edge AI

We've got YOLOv8 running on-device on the Novatek NT98530 camera SoC. Quantized & converted to the SoC's built-in CNN accelerator, doing real-time object detection on the live sensor feed. Part of a from-scratch IP camera stack: RTSP, ONVIF, video pipeline, & now edge computer vision
