ER2ER (EarthRanger to EarthRanger) allows two or more EarthRanger sites to share data seamlessly between each other.
Through this connection, sites can exchange events and subject data securely and automatically enabling cross-site collaboration and shared situational awareness across projects, regions, or partner organizations.

ER2ER is designed for teams that need to monitor and coordinate activities beyond a single deployment, such as cross-boundary wildlife tracking or joint incident response. 

You can follow the specific setup guides below, depending on the type of data you want to share:

• Event Sharing. Learn how to configure your Gundi integration to share EarthRanger events between sites.
• Subject Sharing. Learn how to enable subject (animal or asset) data sharing through Gundi for synchronized monitoring across multiple EarthRanger instances.
