Matter 1.5 builds on the official camera support introduced in 1.5, with 1.5.1 tightening camera behavior to improve performance and overall smart home flexibility.

Cameras can deliver a high-resolution archival stream alongside a lower-resolution stream optimized for mobile viewing.

Video doorbells now support multiple chime tones, enabling more customized setups and automations.

Intercom devices receive clarified signaling rules and built‑in chime support to ensure consistent behavior across platforms.

Streaming formats expand to include HLS and DASH via CMAF, increasing compatibility with cloud and media platforms.

Snapshots can be saved in HEIC format, offering higher quality at smaller file sizes compared with JPEG.

Cameras can push multiple streams in one session, enabling parallel recording, mobile viewing, and AI analysis with device-specific quality settings to reduce bandwidth.

Pan-tilt-zoom cameras gain improved movement and a flexible home position, aiding placements in tight spaces and edge-of-rotation scenarios.

The CSA released Matter 1.5.1 on March 31, 2026, as the latest update in the Matter ecosystem.

Doorbells, chimes, and intercoms can play varied chimes—including seasonal sounds—and trigger automations when chimes start, plus a specific ringtone when prompted by a Matter controller.
