Eufy 4G LTE Cam S330 vs Reolink Altas PT Ultra

Full Smart Cameras comparison in 2026

Updated September 2026
Data from Amazon and official Eufy and Reolink sites.
2026 verdict
The Reolink Altas PT Ultra is the pick for any spot your Wi-Fi can reach, while the Eufy 4G LTE Cam S330 exists for the spots it cannot.
On paper the Reolink pairs an IP65 rating and a 16 month battery figure with 5 GHz Wi-Fi, color night vision, animal alerts and a 2-year warranty. The Eufy 4G LTE Cam S330 is the only one of the two with a 4G LTE modem, and it ships with a 32 GB microSD card and a SIM, so it works on rural land with no Wi-Fi at all. Both are solar-charged 4K pan-and-tilt cameras with a light, a siren, two-way audio and vehicle alerts, and both record to microSD. The Reolink lists RTSP and Home Assistant only through its Home Hub, and the Eufy lists neither RTSP nor Apple Home. Choose the Reolink Altas PT Ultra for a farm yard with Wi-Fi, the Eufy 4G LTE Cam S330 for a gate or field beyond it.

What the differences mean

Connectivity

The Eufy 4G LTE Cam S330 has a 4G LTE modem and a SIM, so it can run with no Wi-Fi at all. The Reolink Altas PT Ultra needs a Wi-Fi network in range, on 2.4 GHz or 5 GHz.

Weather rating

IP65 on the Reolink Altas PT Ultra and IP55 on the Eufy 4G LTE Cam S330. Both are built for outdoor use, and the higher rating is the Reolink's.

Battery rating

The Reolink Altas PT Ultra is rated for 16 months per charge and the Eufy 4G LTE Cam S330 for 1 month. Both rely on solar panels, and the longer figure gives the Reolink a bigger cushion through dull weeks.

Weight and size

The Eufy 4G LTE Cam S330 weighs 1.5 kg, and the Reolink Altas PT Ultra 853g. The Eufy is the heavier unit to mount high on a post or gatepost.

Alerts and night vision

The Reolink Altas PT Ultra also detects animals and lists a privacy zone, and it has color night vision only. The Eufy 4G LTE Cam S330 has both color and black-and-white night vision but does not flag animals.

Hub dependence

The Reolink Altas PT Ultra needs a Reolink Home Hub for RTSP, Alexa and Home Assistant. The Eufy 4G LTE Cam S330 works with Alexa, Google Home and Home Assistant directly, but has no RTSP.

Which one to buy if

What owners say

Owners of both cameras like sharp 4K images, color night vision and local microSD recording with no required subscription, and both groups meet limits in the solar panel and in the software. Eufy 4G LTE Cam S330 owners deploy it on rural gates, coops and building sites where no Wi-Fi exists, praise a connection more consistent than other cellular cameras and the freedom to use cheap third-party data, and they warn that it tracks only people and vehicles, that cellular support varies by country and carrier and that the mount is flimsy. Reolink Altas PT Ultra owners single out the 10-second pre-recording, accurate auto-tracking and metal mounts, while owners in freezing climates report the battery failing to charge and the bundled panel not sustaining 24/7 recording.
