Summary
DoorBird A1103T White Edition is a video door station controllable over HTTP/HTTPS (ports 80/443), RTSP (ports 554/8557), and UDP event broadcasts (ports 6524/35344). This spec covers the LAN-2-LAN API: live video/image, door/light relays, audio, history, schedules, favorites, SIP, session management, and encrypted event monitoring. Auth is HTTP Basic/Digest (RFC 2617) or plaintext http-user/http-password params.
Transport
protocols:
- http
- udp
addressing:

port: 80 # HTTP; HTTPS on 443 (self-signed cert)
auth:
type: basic # RFC 2617 Basic or Digest; also plaintext http-user/http-password params
notes: "Credentials same as DoorBird App user. Wrong creds → HTTP 423 + 1 min block."
Traits
# - powerable # restart.cgi present (restart, not power on/off)
- queryable # info.cgi, sip status, favorites/schedule list return state
- levelable # mic_volume, spk_volume in SIP settings

Macros
# UNRESOLVED: no explicit multi-step sequences documented as macros in source.
Safety
confirmation_required_for:
- open_door # physical door release
- restart # device outage
interlocks:
- "open_door/light_on require watch-always permission or ring event in past 5 min, else HTTP 204 (no-op)."
- "SIP call auto-hangs-up 180 sec after initiation."
- "Only one simultaneous audio/video call; HTTP 503 if busy."
- "Wrong auth → HTTP 423 + 1 min IP/user block."
# UNRESOLVED: relay electrical ratings (voltage/current) not stated in source.
Notes
- Max 1 concurrent API connection per second; HTTP 509 when monitor streams exhausted (8 max).
- Video/audio streams preempted by official DoorBird App — it has precedence.
- AEC/ANR MUST be done client-side for audio-transmit; DoorBird native algorithms not exposed.
- Audio codec fixed: G.711 μ-law, 8000 Hz.
- HTTPS uses self-signed cert (CAs don't issue for IPs). Client must accept it.
- Video/audio streaming over HTTPS not supported in LAN — use sessionid param instead.
- Event monitoring v1 (Argon2i + ChaCha20-Poly1305) deprecated since Nov 2023; v2 (ChaCha20-Poly1305 only) is current.
- SIP P2P supported from device version 000099; SIP listens on port 5060 when enabled.
- Schedule time unit: seconds since Sunday 00:00 UTC; max 604799; all starts must be multiples of 1800.

Known Gaps
- "device-specific hardware specs (voltage, relay ratings, current) not in source. Firmware version compatibility not stated (some features require firmware >= 000108 / 000110 / 000099 / version 129)."
- "no explicit multi-step sequences documented as macros in source."
- "relay electrical ratings (voltage/current) not stated in source."
- "firmware version compatibility ranges (features tied to fw 000099/000108/000110/version 129) — not a single stated range for A1103T."
- "device hardware specs, relay contact ratings, power supply — not in this API doc."
- "exact A1103T-specific RTSP resolution variants — source lists D10x/D21x/D11x variants generically."
