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