|---|---|---|
| Price | $179.99 | $29.99 |
| Release Year | 2024 | 2023 |
| Max Resolution | 5120x1440 (8MP) — a stitched dual-lens panorama, not a 3840x2160 4K frame, despite the 4K marketing | 2K QHD 4MP (2560x1440) |
| Frame Rate at Top Resolution | 15 fps at full resolution, on Reolink's own spec sheet | Not published by TP-Link on the US product page |

| Battery Life Claim | Reolink publishes no runtime in days. It claims only '30% More Battery Life' than an IR camera and '+12 Days Standby', plus '10 minutes of charging can power the camera for 24 hours' | Not applicable — mains powered only |
| Night Vision | ColorX full colour at night from an f/1.0 aperture with the spotlight off. Five 2W 6500K spotlights are there if you want them, at a battery cost | Colour night vision from a starlight sensor plus twin spotlights; 850nm IR to 30ft and an invisible 940nm IR mode |

Reolink's own support article states its battery cameras do 'not support RTSP, RTMP, ONVIF and related communication protocols'; you need the separately sold Reolink Home Hub to expose them | RTSP and ONVIF Profile S. TP-Link states that 'most Tapo cameras, except for battery-powered models' support them, though the C120 is not named in its published model list. Profile S carries no two-way audio, a camera account must be enabled first, and only two of {Tapo Care, SD recording, NVR/NAS/ONVIF} can run at the same time |

Pros & Cons
Reolink Argus 4 Pro with Solar Panel 2
Pros
- +180 degrees with no stitching seam covers a corner or a driveway that would otherwise need two cameras
- +ColorX gives usable colour at night without the spotlight, which is the difference between a night image and a battery drain
- +Dual-band Wi-Fi 6 plus a bundled solar panel plus a 2-year warranty — the best hardware-per-dollar in the battery class
- +No subscription for anything, and the microSD card lives in the camera rather than in a hub you must buy
Cons
- −The '4K' is 5120x1440 from two stitched lenses at 15 fps — it is a panorama, not a 4K frame, and the vertical field is only 50 degrees
- −No standalone RTSP or ONVIF: Reolink's own docs confirm battery cameras need the extra-cost Home Hub before any NVR can see them
- −Reolink publishes no battery runtime figure at all, only relative claims against an unnamed IR camera
- −Sources conflict on the microSD ceiling — 512GB on Reolink's page, 128GB in The Ambient's review
- −No Apple HomeKit support, and reviewers consistently describe the Reolink app as cluttered
TP-Link Tapo C120 (2K QHD Indoor/Outdoor)
Pros
- +$29.99 for a 2K IP66 camera with a 512GB card slot, free AI detection and RTSP is the best value in the category
- +One of only three cameras here that will stream to Blue Iris, Frigate, Synology or a generic NVR
- +Power adapter and a 3-metre cable are both in the box — Wyze charges $19.98 for the outdoor equivalent
- +The 940nm invisible IR mode means no glowing red ring giving the camera away at night
Cons
- −TP-Link limits you to two of {Tapo Care, SD recording, NVR/ONVIF} at once — you cannot run cloud, card and NVR together
- −ONVIF is Profile S only, which excludes two-way audio, and RTSP needs a separate camera account enabled in the app
- −2.4GHz Wi-Fi only, and no frame rate is published anywhere on TP-Link's US page
- −microSD card is not included, and Tapo's US warranty is 1 year on cameras, not the 2 years buyers often assume
- −Wired only — there is no battery or PoE option in this model
