Side-by-Side Comparison
| Spec | eufy eufyCam S3 Pro 2-Cam Kit with HomeBase 3 (T8892) | Arlo Ultra Security Camera 4K HDR, 3rd Gen — 2-Cam Kit with SmartHub (VMS5250-100NAS) |
|---|---|---|
| Price | $429.99 | $349.99 |
| Release Year | 2024 | 2025 |
| Max Resolution | 4K (3840x2160) | 4K (8 megapixel sensor); 2K, 1080p and 720p modes also offered |
| Frame Rate at Top Resolution | Up to 15 fps at 4K, on eufy's own spec sheet | Not published by Arlo. Trusted Reviews' testing found the 4K Ultra 3 records at the same bitrate as the 2K Pro 6, so the extra pixels are paid for in compression rather than detail |
| Field of View | Not published on eufy's US product page for this model | 180 degrees diagonal |
| Power Source | 13,000mAh battery with a solar panel built into the camera. An external panel is a separately sold $29.99 backup for shaded sites | Swappable rechargeable battery, USB-C. Only Arlo-certified USB-C or universal solar panels work; the magnetic-base panels do not |
| Battery Life Claim | Up to 365 days, and eufy claims one hour of daily direct sun keeps it charged indefinitely. eufy quantifies it: the built-in panel gathers 450-900mAh a day against 100-200mAh of average daily use | Up to 6 months (Arlo). Trusted Reviews' tester called four months plus more realistic |
| Night Vision | MaxColor Vision — full colour with no spotlight, from the 1/1.8in sensor and f/1.0 aperture. Identifies faces and plates to about 30ft in low light | Colour night vision driven by the built-in spotlight, with IR black-and-white fallback. Trusted Reviews measured about a second of colour stabilisation after the light fires |
| Weather Rating | IP67 | Weather-resistant, indoor or outdoor; Arlo does not publish an IP rating |
| Wi-Fi / Network | 2.4GHz only (802.11b/g/n). No 5GHz anywhere in this $430 kit | 2.4GHz and 5GHz, but the camera talks to the SmartHub, which Arlo's own FAQ says is required |
| Local Storage | HomeBase 3 with 16GB eMMC built in, expandable to 16TB with a 2.5in SATA drive or SSD you supply. One hub handles up to 16 cameras | SmartHub with a microSD card. The hub is in this 2-camera kit; the microSD card is not, and for a single or add-on camera the hub is not either |
| With No Subscription | Everything. Recording, playback, face recognition and alerts are all local, with no plan at any point | Live view and motion notifications only. Arlo's own FAQ confirms cloud storage, interactive notifications and object detection all stop with the trial |
| Cheapest Plan ($/mo) | 0✓ | 9.99 |
| RTSP / ONVIF / NVR | No RTSP or ONVIF from the cameras. Apple Home works but caps video at 1080p rather than 4K | No RTSP, no ONVIF, no third-party NVR support |
| Warranty | 12 months | 12 months |
| Colors | White | White, Black |

Pros & Cons
eufy eufyCam S3 Pro 2-Cam Kit with HomeBase 3 (T8892)
Pros
- +The only camera here that produces genuinely usable full colour at night without turning a spotlight on, which is also why its battery lasts
- +No subscription, ever — recording, AI face recognition and 16TB of expandable local storage are all included in the hardware price
- +eufy publishes actual solar maths (450-900mAh harvested against 100-200mAh used) instead of the usual 'forever power' hand-waving
- +IP67 and a 13,000mAh cell: this is the least maintenance-hungry outdoor camera in the set
Cons
- −4K runs at up to 15 fps — half the frame rate of the UniFi G6 Instant, and eufy prints it in its own specs rather than hiding it
- −2.4GHz-only Wi-Fi on a $430 kit, when a $99.99 Ring does dual-band Wi-Fi 6
- −Apple Home users get 1080p, not 4K — the HomeKit path throws away most of what you paid for
- −No RTSP and no ONVIF, so despite all the local storage the cameras still will not talk to Blue Iris, Frigate or a third-party NVR
- −The hub is a single point of failure: lose the HomeBase 3 and you lose the recordings on the drive inside it
Arlo Ultra Security Camera 4K HDR, 3rd Gen — 2-Cam Kit with SmartHub (VMS5250-100NAS)
Pros
- +180-degree field of view genuinely removes the blind spots a 140-degree camera leaves at a corner
- +SmartHub is in the box on this kit, so local microSD recording is a card away rather than a $100 accessory away
- +Auto-Zoom and Tracking in 4K is the one feature here that no cheaper camera imitates convincingly
- +USB-C battery and swappable cells mean the camera stays on the wall for its whole life
Cons
- −4K recording and streaming require Arlo's higher Secure Plus tier — on the base plan you get a 4K camera producing 2K files
- −Trusted Reviews found the 4K stream runs at the same bitrate as the 2K Pro 6, so 4K here mostly buys compression artefacts
- −The SmartHub is mandatory. Buy a single Ultra 3 or an add-on camera and it is inert until you also buy a VMB5000
- −The microSD card is never included, on any Ultra 3 SKU
- −$349.99 for two cameras before you have paid a cent of subscription, and no plan means no recording
