1. Issue
PNM camera models with firmware version 2.23.00 experience streaming issues when connected to Milestone VMS. The camera shows "Connection is broken" error in Milestone XProtect, despite being properly registered.
Test Environment:
- Milestone XProtect Corporate 2025 R2 (25.2.1) with Device Pack (13.9.2170.1)
- PNM-9085RQZ1 (f/w: 2.23.00)
- PNM-9085RQZ (f/w: 2.23.00)
Note: The same cameras work correctly with Genetec Security Center 5.13.
2. Root Cause
The RTSP authentication mechanism was modified in firmware 2.23.00 to perform authentication for each RTSP method separately. During each authentication, the session ID changes, causing Milestone VMS to disconnect the stream.
3. Resolution
The issue has been fixed in firmware version 2.23.01, released in December 2025. The fix ensures that the same session ID is used throughout the RTSP authentication process, maintaining compatibility with Milestone VMS.
Workaround (for 2.23.00): Downgrade to firmware version 2.22.02 or 2.22.03.
