What the differences mean
Power
The Reolink Altas PT Ultra runs on a battery charged by its bundled solar panel and needs no cable. The Reolink OMVI 3i PoE draws power and data from a single Ethernet cable, so it is fixed in place but unaffected by sun or temperature.
Pre-recording
The Reolink Altas PT Ultra keeps a rolling buffer so a triggered clip includes the ten seconds before motion started, which catches fast-moving people and cars. The Reolink OMVI 3i PoE records continuously, so nothing needs to be buffered.
Coverage
The Reolink Altas PT Ultra has a 90 degree horizontal view on a 355 degree pan and 90 degree tilt head. The Reolink OMVI 3i PoE holds a fixed 180 degree panorama while a second lens tracks, so it watches the whole scene at once.
Cold weather
The Reolink Altas PT Ultra is known to stop powering or charging in sustained sub-freezing weather, a battery limitation. The wired Reolink OMVI 3i PoE has no battery, so cold does not affect it the same way.
RTSP and ecosystem
The Reolink Altas PT Ultra needs a Reolink Home Hub for RTSP, Alexa and Home Assistant. The Reolink OMVI 3i PoE exposes RTSP directly and works with Home Assistant without extra hardware, though neither supports Apple HomeKit.
Which one to buy if
- no cable can reach and the spot gets good sun
The Reolink Altas PT Ultra runs wire-free on a panel that keeps its battery topped up in sunny and mild climates.
- you need true 24/7 recording
The Reolink OMVI 3i PoE records continuously, since its solar sibling cannot sustain round-the-clock video.
- you want to capture the seconds before an event
The Reolink Altas PT Ultra has a 10-second pre-recording buffer the wired model does not need.
- you want RTSP and Home Assistant without a hub
The Reolink OMVI 3i PoE streams RTSP directly, while the Altas needs a Reolink Home Hub.
- you live where it freezes for days
The wired Reolink OMVI 3i PoE has no battery to fail in the cold.

What owners say
Owners of both Reolink cameras praise the same qualities: a sharp 4K image, accurate people, animal and vehicle detection, and subscription-free local storage. Reolink Altas PT Ultra owners single out the 10-second pre-recording, which lets them see a whole event rather than a clip that starts late, and they rate the ColorX colour night vision and the pan-tilt with return-to-preset highly. Their warnings are clear: the bundled solar panel cannot keep up with true 24/7 recording, the battery can stop working in sub-freezing weather, and RTSP or Alexa need a Reolink Home Hub. Reolink OMVI 3i PoE owners instead talk about the 180 degree panoramic view and the tracking lens, calling the wide shot crisp and the mount solid, while noting slower close-up tracking, heavy default notifications and support limited to Google Home and Home Assistant.
Frequently Asked Questions
Which is better overall: Reolink Altas PT Ultra or Reolink OMVI 3i PoE?
For a wire-free spot in a sunny, mild climate, the Reolink Altas PT Ultra wins on freedom, pre-recording and price. Where a cable can be run, the Reolink OMVI 3i PoE is the more dependable camera, recording 24/7 from a fixed 180 degree panorama with direct RTSP.
What is the biggest difference between the Reolink Altas PT Ultra and the Reolink OMVI 3i PoE?
Power and reliability. The Reolink Altas PT Ultra runs on solar and battery, which limits it to event recording and struggles in freezing weather, while the Reolink OMVI 3i PoE is wired for continuous 24/7 recording.
Can the Reolink Altas PT Ultra and the Reolink OMVI 3i PoE record 24/7?
Only the Reolink OMVI 3i PoE does reliably. The Reolink Altas PT Ultra can start recording on a schedule, but its bundled solar panel cannot keep the battery up under continuous 24/7 use, so event recording is the realistic mode.
Do these Reolink cameras need a subscription?
No. Both store footage locally with no monthly fee, the Reolink Altas PT Ultra to a microSD card up to 512GB and the Reolink OMVI 3i PoE to a microSD card, an NVR or FTP/NAS. A subscription is only optional for cloud storage.
Which works with Alexa, Home Assistant or RTSP?
The Reolink Altas PT Ultra supports Alexa, Home Assistant and RTSP only through a Reolink Home Hub. The Reolink OMVI 3i PoE offers RTSP and Home Assistant directly, with no Alexa. Neither supports Apple HomeKit.
Who should buy the Reolink Altas PT Ultra?
Owners of a large or remote property in a sunny, mild climate who want wire-free 4K pan-tilt coverage, pre-recording and fully local storage with no subscription.
