From f728b0002cac5f266b1543c5a1ac24d6a38b9a97 Mon Sep 17 00:00:00 2001 From: Mitchell R Date: Sat, 23 May 2026 02:25:44 +0200 Subject: [PATCH] feat(cloud-cameras): Hik-Connect + Dahua + Tuya + Uniview + TP-Link integrations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cloud camera platform integrations with provider interface pattern: Framework (cloud-cameras/types.ts): - CloudCameraProvider interface: testCredentials, listCameras, getStreamUrl, credentialFields - CloudAccount model + vendor registry - Multiple accounts per vendor per tenant supported - All auth on server — kiosk only gets streaming URLs Vendors: - Hik-Connect: token auth, device list via OpenAPI, local RTSP (cloud P2P relay requires native SDK — not supported yet) - Dahua: HTTP Basic/Digest against device ISAPI, channel enumeration, RTSP URL construction per channel - Tuya: OAuth2 + HMAC-SHA256, device list + stream allocation via IoT Cloud API, RTSP/HLS URL from allocate endpoint - Uniview: HTTP Basic against LightAPI, channel enumeration via /LAPI/V1.0/Channels, RTSP per channel - TP-Link: no cloud API, direct RTSP + TCP port probe for testing DB: cloud_accounts table (SQLite migration) for storing encrypted credentials per vendor per tenant. Admin UI for account management TODO — provider framework + DB ready. --- .../src/plugins/service-store/migrations.ts | 16 ++ server/src/shared/cloud-cameras/dahua.ts | 89 +++++++++++ server/src/shared/cloud-cameras/hikconnect.ts | 101 ++++++++++++ server/src/shared/cloud-cameras/index.ts | 18 +++ server/src/shared/cloud-cameras/tplink.ts | 56 +++++++ server/src/shared/cloud-cameras/tuya.ts | 147 ++++++++++++++++++ server/src/shared/cloud-cameras/types.ts | 99 ++++++++++++ server/src/shared/cloud-cameras/uniview.ts | 88 +++++++++++ 8 files changed, 614 insertions(+) create mode 100644 server/src/shared/cloud-cameras/dahua.ts create mode 100644 server/src/shared/cloud-cameras/hikconnect.ts create mode 100644 server/src/shared/cloud-cameras/index.ts create mode 100644 server/src/shared/cloud-cameras/tplink.ts create mode 100644 server/src/shared/cloud-cameras/tuya.ts create mode 100644 server/src/shared/cloud-cameras/types.ts create mode 100644 server/src/shared/cloud-cameras/uniview.ts diff --git a/server/src/plugins/service-store/migrations.ts b/server/src/plugins/service-store/migrations.ts index fa3980a..242f6af 100644 --- a/server/src/plugins/service-store/migrations.ts +++ b/server/src/plugins/service-store/migrations.ts @@ -968,6 +968,22 @@ export const MIGRATIONS: readonly MigrationEntry[] = [ addColumnIfNotExists(db, "kiosks", "encrypt_key_encrypted", "TEXT"); }, + // Cloud camera accounts: per-vendor, multiple accounts per vendor. + // Credentials encrypted with server secret.
