Reolink Argus 4 Pro (Battery, dual-lens 4K) review 2027

What problem does the Reolink Argus 4 Pro solve?

The Argus 4 Pro sees more of a garden than any other camera here and asks for no monthly fee. That is the short version of its 8.4 score and its second place in a test of eight home security cameras. The problem it solves is coverage: a single unit mounted on one corner covers a 180° field of view, so a wide garden does not need two cameras pointed at each other. The second problem it solves is cost over time. Person, vehicle and animal detection run on the camera itself and cost nothing, and footage records to a microSD card or a Reolink NVR. Add the optional solar panel and it becomes the best no-subscription outdoor camera after the eufy.

How did we score the Reolink Argus 4 Pro?

We scored it across five criteria, and the breakdown shows where the points came from.

• Video & night quality: 23 out of 25. This measures daytime detail at 5 m, night clarity in infrared and colour, field of view, and HDR against a bright sky. The 180° view and colour night footage carried it here.
• Detection & alerts: 15 out of 20. This measures person, package, vehicle and animal detection accuracy on staged events, the seconds from event to phone, and false alerts per day. Our measured event-to-alert time was 6 seconds.
• Storage & subscription: 20 out of 20. This measures what works without a subscription, local storage, and cloud plan price per camera and per home. The Argus 4 Pro took full points.
• Install & power: 11 out of 15. This measures battery life at our event rate, solar or wired options, mounting, weather rating and Wi-Fi reach. Battery measured 2 months without the solar panel.
• Value: 15 out of 20. This measures price plus three years of the subscription needed for the headline features. Our measured 3-year cost was $150.

What does the Argus 4 Pro do best?

The 180° field of view covered the whole garden from one corner, which no other camera in this test matched. Colour night vision worked from ambient light alone, with no spotlight needed. Person, vehicle and animal detection runs on the camera and is free. Footage records to microSD or a Reolink NVR, and RTSP support makes it usable with home servers. Our measured event-to-alert time was 6 seconds, and battery measured 2 months without the solar panel. The measured 3-year cost was $150.

How do the dual-lens 4K and ColorX night vision work?

Two 2K lenses sit side by side and their images are stitched into one 4K frame covering 180°. That is why one camera can watch a wide garden instead of two. ColorX colour night vision uses the sensor's sensitivity to ambient light to produce colour footage after dark without switching on a spotlight or infrared illuminator. Both technologies are named in the spec sheet; the stitched seam is the visible trade-off of the first.

What is the Argus 4 Pro made of?

The spec sheet lists the parts that matter. The optics are a dual-lens 4K array, described as dual 2K stitched, with a 180° field of view. Power comes from a battery, with an optional solar panel. Local storage is a microSD card up to 128 GB or a Reolink NVR. Night vision is ColorX colour night vision, which needs no light. The camera works with Reolink, Alexa and Google Home. There is no subscription requirement and the cloud plan price is 0 USD/mo.

How does it compare with the eufy, Nest Cam and Blink?

The eufy SoloCam S340 scored 8.8 at $199.99, ahead of the Argus 4 Pro's 8.4. The eufy offers 3K wide plus a 2K telephoto lens, 360° pan and 70° tilt, 12 months of measured battery life and 8 GB of built-in storage. The Argus 4 Pro answers with a wider fixed 180° view and a lower price, but the eufy lasts longer between charges and pans.

The Google Nest Cam (battery) scored 7.8 at $179.99. It has the most accurate detection in the test and the best app, but only 1080p HDR, a 130° field of view, infrared-only night vision, no local storage and an 8 USD/mo cloud plan. The Argus 4 Pro beats it on resolution, field of view, night vision and running cost.

The Blink Outdoor 4 scored 7.6 at $99.99. It ran 18 months on two AA batteries in our test and stores clips on a Sync Module, but it is 1080p with a 143° view and infrared night vision. The Argus 4 Pro costs more but records in 4K with colour night vision.

Where does the Argus 4 Pro fall short?

The stitched seam is visible on close objects, a direct consequence of joining two lenses into one frame. Battery measured 2 months without the solar panel, which is short next to the eufy's 12 months and the Blink's 18 months. The app is plainer than Nest or Arlo. Those three points are why it lost marks on install and power and why it sits behind the eufy overall.

Is the Argus 4 Pro good value?

It costs $149.99. Our measured 3-year cost was $150, because the cloud plan price is 0 USD/mo and the features people actually use run on the camera. Nothing in the headline feature set requires a subscription.

Who should buy the Reolink Argus 4 Pro?

It suits wide gardens, where one 180° camera replaces two narrower ones, and home-server users, who can record to a Reolink NVR or pull the stream over RTSP. Buyers who want the longest possible battery life should add the solar panel or look at the eufy instead.
