Reolink Argus 4 Pro (with Solar Panel)
- Wi-Fi
Verified September 2026
The best battery outdoor camera for HA users who can't run cable: 4K 180° dual-lens with genuinely usable colour night vision, and the bundled 6W solar panel keeps the 5000mAh battery topped up through most UK weather (Reolink quotes 10 minutes of sun for a day's runtime, plus ~12 extra standby days over IR-only models). Unlike the mains-powered Elite WiFi and Lumus already on this list, there's no built-in siren here — two-way audio only, so lean on Home Hub automations rather than an on-camera scare-off. Battery Reolinks also need a Home Hub or NVR to appear in Home Assistant at all, so budget ~£90 extra for that; once hubbed, everything stays local.
In Home Assistant
| Control | Type | What it does |
|---|---|---|
| Battery | Sensor (%) | Percentage battery; refresh cadence follows the hub's wake schedule, not a fixed poll interval. |
| Battery state | Sensor | Discharging/charging/charge-complete — the only local proxy for solar panel output since there's no separate solar sensor. |
| Battery temperature | Sensor | Pushed on the same wake events as battery level. |
| Motion/person/vehicle/animal detection | Binary sensor | PIR-classified event entities that double as the camera's wake trigger, so the first event after a sleep period can lag slightly versus a wired camera's always-listening stream. |
| PIR sensitivity | Number | Adjustable detection sensitivity, letting you tune wake frequency to balance battery life against event latency. |
Through the Home Hub, the Argus 4 Pro registers in Home Assistant as its own independent device rather than a child entity nested under the hub, so automations can target the camera directly with a full set of camera, sensor and binary sensor entities. Because it's battery-powered, most non-critical entities only get pushed on a genuine wake event — a PIR trigger, more than an hour since the last update, a hard multi-hour ceiling if it's stayed quiet, or a hub-wide cap that forces every battery camera on that hub to check in together — rather than continuous polling. There's no dedicated solar-panel entity; panel output only shows up indirectly as the battery-state sensor flipping to charging while daylight hits the panel, so a camera that never reports charging on a sunny day is your only local signal the panel's misaligned, shaded, or disconnected.
