Which is better for a site with no Wi-Fi?

The SEHMUA. It connects over 4G LTE and runs on a solar panel, so it needs neither home broadband nor an outlet. The Arlo Ultra needs Wi-Fi through a SmartHub.

Is the Arlo Ultra worth the extra over the SEHMUA?

If you have Wi-Fi, yes for image quality. The Arlo shoots 4K HDR against 2K, adds color night vision and AI detection, and was $199.99 at Walmart as of November 7, 2026. The SEHMUA wins on placement freedom, not detail.

Which has better night vision?

The Arlo Ultra. It has color night vision plus IR and a spotlight. The SEHMUA lists night vision but no color mode.

Do either need a subscription?

The SEHMUA records to an SD card and includes a 30-day cloud trial, so local recording works without paying. The Arlo includes an Arlo Secure trial; people, vehicle and package detection and 60-day cloud history need the plan after it ends.

Which covers more area?

The SEHMUA. Its motorized head pans 350° and tilts 100°, giving a full 360° sweep. The Arlo Ultra has a fixed 180° lens.

What else do I need to buy for the Arlo?

An Arlo SmartHub, which is sold separately and required for operation. The SEHMUA needs a cellular data plan, purchased in its app.
