New Features NVR Channel Dashboard — NVR detail screen now displays connected channels in a grid with live snapshot thumbnails for each channel, including channel name, status, and IP. VPN Detection Warning — App now detects active VPN connections and warns the user that local network features (camera discovery, streaming) may not work. Check runs at startup and again on every network scan, so users are notified even if they enable a VPN mid-session. Fixes & Reliability LAPI / Uniview Snapshots — Fixed snapshots not loading on Uniview IPC and NVR channels by correcting the LAPI snapshot URL pattern and digest auth handling. RTSP Frame-Capture Fallback — When all HTTP/ISAPI/LAPI/ONVIF snapshot endpoints fail, the app now extracts a single frame from the RTSP sub-stream as a last-resort thumbnail. This is required for: IP cameras with no HTTP snapshot endpoint exposed Third-party ONVIF cameras added to a Uniview NVR (channels the NVR cannot proxy snapshots for) VPN False-Positive Fix — VPN detector now requires a routable IPv4 address on the tunnel interface, eliminating false positives from iOS/macOS background utun interfaces (Handoff, AirDrop, AWDL) that persist after disconnecting a VPN.
