Why it is worth attention

Provides a full stack for ONVIF interaction—core library with minimal dependencies, a ready‑to‑run dashboard with visual PTZ and preview, and a CLI for scripting—all under the Apache 2.0 license.

Who it is for

Java developers integrating ONVIF into applications
System integrators managing IP cameras and surveillance devices
DevOps engineers needing headless automation for camera control
Security camera administrators seeking a browser‑based management UI

Use cases

Discover ONVIF‑compliant cameras on a local network
Retrieve device info, profiles, and RTSP stream URIs programmatically
Control PTZ movements via interactive dashboard or CLI scripts
Monitor device events and perform system maintenance (reboot, reset)

Strengths

Self‑contained core JAR with only SLF4J as runtime dependency
Three complementary interfaces (library, dashboard, CLI) for varied workflows
Pre‑built releases for dashboard and CLI (Linux/Windows) simplify deployment
Covers major ONVIF services: Device, Media, PTZ, Imaging, Events, Recording

Considerations

Requires JDK 17+ and Maven for building from source
Java‑only; not available as a native library for other languages
ONVIF support is limited to standard profiles; may not cover all vendor extensions

README quick start

link-onvif-client

link-onvif-client is a Java toolkit for ONVIF protocol device discovery and management:

onvif-client-core — Core library. Implements WS-Discovery, SOAP/XML messaging, WS-Security authentication, and all major ONVIF services (Device, Media, PTZ, Imaging, Events, Recording). Packaged as a single JAR with no runtime dependencies beyond SLF4J.
onvif-dashboard — Web application. Spring Boot backend + SPA frontend, providing a simple dashboard page for device discovery, configuration, PTZ control, and live preview.
onvif-cli — Command-line interface. Built on picocli, enables direct ONVIF operations from the terminal with support for both interactive and scripted usage.

Features

Device discovery — WS-Discovery multicast probe for ONVIF devices on the LAN
Device management — Query and configure device info, hostname, network, users, date/time, NTP, DNS, and system maintenance (reboot, factory reset)
Media streaming — Enumerate profiles, video/audio sources and encoder configurations; retrieve RTSP stream URIs and snapshot URIs
PTZ control — Continuous, absolute, and relative moves; preset management; home position
Imaging — Read and adjust brightness, contrast, sharpness, focus; move/stop focus
Event subscription — Pull-point and push-mode event monitoring
Recording — Query recording service capabilities and recording list
Dashboard visual UI — Real-time device discovery, PTZ panel, stream preview, and event display
CLI — Discover, interrogate, and control devices from the command line, suitable for automation and headless environments

onvif-client-core

A self-contained ONVIF library — single JAR with only SLF4J as a runtime dependency, feature-complete for device interaction. Add it to your project and start working with ONVIF devices immediately.
