What the differences mean

Continuous recording

The Reolink Altas PT Ultra can keep a 24/7 video history, although its owners say the bundled panel cannot sustain it for long. The Reolink Argus PT Ultra + Solar Panel records events only and sleeps in between, which is what keeps its battery topped up.

Battery

The Reolink Altas PT Ultra is rated for 16 months per charge, which is why it is the heavier camera. Reolink does not publish a battery life for the Argus PT Ultra, but its owners report the panel keeping it near full.

Tilt range

Both pan 355 degrees, but the Reolink Argus PT Ultra + Solar Panel tilts 140 degrees against 90, so it can look further down at a porch or up a slope from the same mount.

Size and weight

At 481g the Reolink Argus PT Ultra + Solar Panel is little more than half the 853g of the Reolink Altas PT Ultra, which makes it easier to mount on a fence post or a soffit.

Alexa and privacy zones

The Reolink Argus PT Ultra + Solar Panel works with Alexa. The Reolink Altas PT Ultra supports Google Home only among the voice assistants. Both let you mask parts of the image with privacy zones.

Which one to buy if

What owners say

Owners of both Reolink cameras praise sharp 4K video, color night vision, no subscription and Reolink's support, and both groups note that Home Assistant and RTSP depend on the Reolink Home Hub. Reolink Altas PT Ultra owners single out the pre-recording that shows an event from its start, the metal mounts and accurate tracking, but they warn that the bundled panel cannot keep up with round-the-clock recording and that the battery can quit in long freezing spells. Reolink Argus PT Ultra + Solar Panel owners report the battery sitting near full on solar even through winter and many run whole fleets of them, while their complaints are about the camera sleeping between events and reloading for live view, a Home Hub that sometimes needs resets and no microSD card in the box.
