AI & DATA SOFTWARE PLATFORM
Hearth®
Turn motion into intelligence
Develop, integrate and deploy Event-Based Vision applications on embedded systems with Hearth, Prophesee’s next-generation software and AI platform.
Built on a modular microservices-centric architecture designed for scalability, Hearth is an AI & compute platform bringing Prophesee-optimized algorithms, AI and application components across sensor, edge and cloud environments to help you get the most from your Event-Based Vision application.

Trusted and sovereign by design
Industrial-quality software with cybersecurity and compliance addressed from sensor to decision, including CRA and EU AI Act requirements, sovereign deployment options, AI governance and auditability for critical decisions.
Robust multimodal perception
Combine event, RGB or infrared, IMU and time-of-flight data – intrinsically or at system level – to strengthen perception in degraded and fast-moving environments through complementary sensing.
Ecosystem-ready integration
Compatibility with mainstream robotics and smart-system frameworks, with integration accelerators for embedded Linux and edge AI and support for integrator and OEM workflows.
Edge-scalable performance
A computing-hardware abstraction layer optimized for embedded real-time systems, scaling from ultra-low-power modules to larger systems while preserving low latency and compact deployment.
From event data to application intelligence
Hearth brings together the tools needed to explore event data, develop perception pipelines and prepare applications for integration.
Visualize, record and tune
Use a graphical environment to explore live and recorded event data from supported Event-Based Vision systems.
- Visualize event streams and provided datasets
- Control visualization parameters, including accumulation time and fps rate
- Record and replay event data
- Export visualizations to AVI video
- Configure, save and load sensor settings

Develop with C++ and Python
Build Event-Based Vision applications through comprehensive C++ and Python APIs.
- Run natively on Linux and Windows
- Connect to Prophesee-compatible vision systems
- Access extensive documentation and code examples
- Develop through available training and learning resources
// Count and time-stamp events from an event-based camera
#include <hearth/sdk/driver/camera.h>
#include <hearth/sdk/base/events/event_cd.h>
class EventAnalyzer {
public:
int global_counter = 0; // events processed
Hearth::timestamp global_max_t = 0; // highest timestamp
// camera callback: statistics on the received events
void analyze_events(const Hearth::EventCD *begin,
const Hearth::EventCD *end) {
global_max_t = (end - 1)->t;
for (const Hearth::EventCD *ev = begin; ev != end; ++ev) {
++global_counter;
}
}
};Applications
that grow with the platform
Hearth brings together Prophesee algorithms, AI components and a growing library of application software for building Event-Based Vision systems – from event-data exploration and calibration to machine learning, computer vision and application analytics.
