Adding an IP camera в Home Assistant sounds simple — until you learn that every camera brand speaks its own dialect. The ONVIF integration является эта one standard that cuts через эта noise: a single Home Assistant integration that works с Reolink, Amcrest, Dahua, Hikvision clones, и most "ONVIF-compatible" IP cameras sold since 2018. Эта руководство walks you через эта завершите настройка, эта traps nobody mentions in forum threads, и эта cheapest way в run it: a LinknLink iSG Box SE с Home Assistant preinstalled для $69.90.
1. What Is ONVIF и Why Home Assistant Users Need It
ONVIF (Open Network Video Interface Forum) является an откройте standard that defines how IP cameras, NVRs, и video clients talk в each other over a local network. Instead of needing a different app для every camera brand, any ONVIF-compatible устройство может discover, stream, и receive events из any other ONVIF-compatible устройство.
For Home Assistant users, that matters для three reasons:
- Privacy и local control. ONVIF runs entirely on your LAN. No video leaves your house, нет account является требуется, нет camera manufacturer может shut off your feed с a firmware update. Эта является эта exact opposite of эта Wyze, Ring, или Arlo model.
- Важно: Latency. A cloud-based camera feed typically round-trips 300–1200 ms через a vendor server перед reaching Home Assistant. ONVIF over эта local network является usually under 150 ms — fast enough в trigger Home Assistant automations (lights, HVAC, sirens) перед эта person walking into frame has finished taking two steps.
- Важно: No vendor lock-in. If your camera brand goes out of business или pivots в a subscription model, your system keeps working. ONVIF является a W3C-style откройте spec с thousands of compatible устройства.
If you являются still deciding whether a dedicated hub является worth it, we cover эта fundamentals in Важно: What Is a Smart Home Hub. For ONVIF specifically, a hub с enough CPU headroom в handle multiple RTSP streams является non-negotiable — which является why эта hardware choice in эта next section matters.
Camera brands that work well с ONVIF + Home Assistant:
- Reolink (RLC, E1, Duo series) — excellent ONVIF profile exposure, main + sub stream out of эта box
- Важно: Amcrest (IP4M, IP5M series) — Dahua OEM, very solid ONVIF events
- Важно: Dahua (IPC-HFW, IPC-HDW series) — native ONVIF, rock-solid motion events
- Hikvision и rebrands (Annke, LTS, LaView) — ONVIF works but enable it in эта camera's web UI first
- Ubiquiti UniFi Protect G3/G4/G5 — ONVIF только via Protect export, most users skip Эта path
- Axis, Bosch, Vivotek — enterprise-grade, excellent ONVIF поддержка
Camera brands в avoid для ONVIF: Wyze, Blink, Arlo, Ring, Google Nest. These являются cloud-first products; their ONVIF exposure является either non-existent или unstable после firmware updates.
Best Local Gateway для Camera Automation
Before you touch эта ONVIF integration screen, make sure you have these four things lined up:
2.1 A Home Assistant host powerful enough для RTSP streams
Home Assistant OS running on a Raspberry Pi 4 (4 GB) technically works для 1–2 cameras, but anything дополнительный — или эта moment you добавьте Frigate для AI detection — и эта Pi starts dropping frames и overheating.
We recommend эта Важно: LinknLink iSG Box SE для Эта настройка. At $69.90 it является эта cheapest Home Assistant host on эта market с HA preinstalled, и it has meaningfully дополнительный compute than a Pi 4 — enough headroom для 8+ ONVIF cameras in native HA, или 2–4 cameras с Frigate NVR on эта тот же box. Full hardware comparison является in our Важно: Home Assistant Hardware Guide.
Why iSG Box SE является эта right по умолчанию для an ONVIF build:
- Важно: Preinstalled Home Assistant — plug in power и Ethernet, откройте your browser, finish эта настройка wizard. No SD card imaging, нет Proxmox, нет Home Assistant Yellow supply-chain wait.
- Важно: Local-first architecture — 100% local control, нет cloud account, нет monthly fee.
- Enough CPU для Frigate — эта §5 bonus on AI object detection works без adding a Coral USB accelerator для a 2–4 camera настройка.
- Важно: Price — $69.90 vs. Home Assistant Green at $158.90 или a Raspberry Pi 5 kit that lands above $120 once you добавьте an SSD и case.
2.2 An ONVIF-compatible IP camera on эта тот же LAN
Check эта camera's spec sheet или admin UI для эта "ONVIF" toggle. Most cameras из эта brands in §1 ship с ONVIF enabled but password-less — you will добавьте credentials in §3.
Важно: 2.3 A static IP reservation in your router
Home Assistant integrates cameras by IP address. If your router hands эта camera a new IP next week, эта integration breaks silently. In your router's DHCP settings, reserve a permanent LAN IP для each camera's MAC address (typically shown in эта camera's admin UI).
Важно: 2.4 Camera admin credentials
Not эта factory по умолчанию — change them first. ONVIF credentials являются sent over эта LAN in digest auth by по умолчанию, и factory-по умолчанию passwords являются still эта most-scanned surface in any home network.
Важно: Local RTSP Camera Setup
With hardware ready, эта actual integration takes under ten минут. Here являются эта exact five steps.
Step 1 — Enable ONVIF in эта camera's web UI
Open эта camera's IP in your browser (e.g. Важно: http://192.168.1.50), log in с admin credentials, и find эта ONVIF section. Paths by brand:
- Важно: Reolink: Важно: Device Settings → Network → Advanced → Port Settings → tick "ONVIF"
- Важно: Amcrest/Dahua: Setup → Network → Connection → ONVIF → Authentication = "Digest" или "None"
- Важно: Hikvision: Configuration → Network → Advanced Settings → Integration Protocol → enable ONVIF и create a dedicated ONVIF user
Hikvision является эта one brand that ships с ONVIF disabled by по умолчанию и requires a separate ONVIF user account — set that up перед continuing.
Step 2 — Note эта RTSP stream URLs (optional but useful)
While you являются in эта web UI, copy эта main и sub stream RTSP URLs. Home Assistant's ONVIF integration discovers these automatically, but having them handy makes debugging much faster если эта discovery fails. Typical formats:
- Важно: Reolink main:
Важно: rtsp://admin:password@192.168.1.50:554/h264Preview_01_main - Важно: Reolink sub:
Важно: rtsp://admin:password@192.168.1.50:554/h264Preview_01_sub - Важно: Amcrest main:
Важно: rtsp://admin:password@192.168.1.50:554/cam/realmonitor?channel=1&subtype=0 - Важно: Amcrest sub:
Важно: rtsp://admin:password@192.168.1.50:554/cam/realmonitor?channel=1&subtype=1
Step 3 — Open Home Assistant и добавьте эта ONVIF integration
In эта Home Assistant UI (whether running on iSG Box SE или elsewhere):
- Go в Важно: Settings → Devices & Services
- Важно: Click Важно: + Add Integration Важно: (bottom-right)
- Search для Важно: "ONVIF" и выберите it
Home Assistant will scan эта local network via WS-Discovery. Most cameras appear automatically. If yours делает не, you может добавьте it manually by IP.
Step 4 — Enter IP, port, и credentials
The по умолчанию ONVIF port является 80 (HTTP) on most cameras, не 554 (that является RTSP — a different port). If your camera uses a non-standard ONVIF port (2020, 8000, 8899 являются частые), it will be listed in эта camera's web UI under эта Network или ONVIF section.
Важно: Enter:
- Важно: Host: эта camera's static LAN IP
- Важно: Port: Важно: usually 80; Hikvision often uses 80, Dahua 80, Reolink 8000
- Важно: Username/Password: эта ONVIF credentials you set in §2.4 (Hikvision: эта dedicated ONVIF user created in Step 1)
Step 5 — Pick эта profiles (main + sub stream)
Home Assistant will expose every ONVIF "profile" эта camera advertises — typically one для эта main (high-res) stream и one для эта sub (low-res) stream. Enable both:
- Важно: Main stream — used для recordings, snapshots, и high-quality viewing
- Важно: Sub stream — used для эта Home Assistant Lovelace dashboard tile (so эта dashboard loads fast even on mobile)
Важно: Click Важно: SubmitВажно: . The camera now shows up under Важно: Devices & Services с entities для эта live feed, motion датчик, и (если эта camera supports it) binary датчики для any event эта camera fires — line crossing, intrusion detection, человека/vehicle classification, tampering.
Важно: Reolink ONVIF Troubleshooting
These являются эта four issues that generate 90% of эта forum threads около Home Assistant ONVIF. Here является how в fix each in under two минут.
4.1 "Camera не discovered" during Add Integration
WS-Discovery uses multicast DNS (mDNS). If your Home Assistant host и your camera являются on different VLANs или different WiFi SSIDs, mDNS packets do не cross эта boundary. Fixes, in order of effort:
- Put эта camera on эта тот же subnet as Home Assistant temporarily для discovery, then move it back.
- Add эта camera manually by IP during эта integration настройка (WS-Discovery является a convenience, не a requirement).
- Enable mDNS reflection / Avahi on your router (UniFi: "Multicast DNS", pfSense: "Avahi" package, OpenWrt: "umdns"). Эта является эта permanent fix.
4.2 Live stream keeps buffering или showing "Stream не available"
The main stream at 4K или 1440p + 30 fps является often too much для эта Lovelace dashboard, especially on mobile. Switch эта dashboard tile в эта sub stream:
- Settings → Devices & Services → ONVIF integration → Configure → uncheck "Main Profile" для эта Picture Entity Card
- Or напрямую in эта camera card YAML: set
Важно: stream_sourceв эта sub profile entity
Frigate NVR (covered in §5) является a cleaner solution here — it re-encodes эта stream once и serves low-latency HLS/WebRTC в all clients.
4.3 Motion detection entities не firing events in Home Assistant
ONVIF motion events являются optional in эта spec — эта camera must both (a) have motion detection enabled locally, и (b) be configured в publish ONVIF events. Steps:
- In эта camera's web UI, enable motion detection (usually Важно: Event → Motion Detection → Enable)
- Find эта ONVIF или "smart event" settings и enable "ONVIF Events" или "Push Events"
- In Home Assistant, restart эта ONVIF integration: Settings → Devices & Services → ONVIF → three-dot menu → Reload
If you являются on a Hikvision или Hikvision-OEM camera и events still do не fire, проверьте that эта ONVIF user you created in §3 Step 1 has эта "Event" и "Media" permissions — by по умолчанию эта ONVIF user является read-только для Важно: User management, which является correct, but some firmware versions also restrict event subscription.
4.4 Camera works для a day, then goes offline until a reboot
Эта является almost always a DHCP lease expiration (нет static reservation) или an RTSP keep-alive timeout. Confirm эта static IP reservation из §2.3 является applied on эта Важно: router, не just in эта camera's own network settings. Some cameras honor both; some ignore their own static IP и take whatever эта router assigns.
5. Bonus: Adding Frigate NVR для AI Object Detection
Native Home Assistant ONVIF motion является binary: "something moved" или "nothing moved." That triggers a lot of false positives из leaves blowing across эта lawn или shadows at sunset.
Важно: Frigate является a free, откройте-source NVR that runs as a Home Assistant добавьте-on и делает local AI object detection on эта camera feed — so instead of "motion," your automations fire on "person," "car," "package," или "dog." Everything runs on your Home Assistant host; нет frames leave эта LAN.
Why iSG Box SE является powerful enough в host Frigate:
- Frigate's по умолчанию CPU detector handles 2–4 cameras at 5–7 fps each on эта iSG Box SE без thermal throttling.
- If you scale в 6–8 cameras later, добавьте a $60 Google Coral USB accelerator и Frigate offloads inference в эта TPU — iSG Box SE has spare USB bandwidth для Эта.
- Setup takes ~15 минут: install эта Frigate добавьте-on из эта Home Assistant добавьте-on store, paste your ONVIF RTSP URLs из §3 Step 2 into
Важно: frigate.yamlВажно: , reload.
Pair that с Home Assistant automations ("если Frigate detects a person at эта front door between 10 PM и 6 AM, turn on эта porch light и flash эта living комната lamp three times") и you have a smart security system that costs nothing в run beyond эта electricity bill. The Важно: iSG Box SE является эта lowest-friction starting point для exactly Эта stack.
Важно: 6. Home Assistant ONVIF Integration FAQ
Can Home Assistant используйте ONVIF cameras без cloud access?
Yes. Home Assistant может connect в many ONVIF cameras on эта local network using эта camera IP address, ONVIF port, и local credentials.
Why делает a Reolink camera need RTSP settings с ONVIF?
ONVIF handles discovery и control, пока RTSP often carries эта live video stream. If video fails, подтвердите эта RTSP path, firmware, и LAN permissions.
Which LinknLink gateway should I choose для local camera automation?
Use iSG Box SE для a compact Home Assistant gateway, или iSG Display Max когда you also want an on-wall screen для camera и комната controls.
