Reolink Duo Floodlight WiFi 4K 180 Degree Dual-Lens Wi-Fi Floodlight Camera

Is the Reolink Duo Floodlight WiFi worth buying?

The Reolink Duo Floodlight WiFi 4K 180 Degree Dual-Lens Wi-Fi Floodlight Camera is a floodlight camera that records at 4K 8MP. It is best for lighting up and recording a driveway or yard at night.

What it does well: no subscription needed to record, 4K 8MP detail, person detection on the device and colour night vision.

At $169.99 on Amazon today, it has a mid-range price: 2 of the 5 floodlight cameras we track cost less.

Does the Reolink Duo Floodlight WiFi need a subscription?

No. It records to a microSD card, a recorder, Reolink's hub or network storage with no monthly fee; Reolink Cloud Standard is optional and adds cloud backup.

Smart detection works without a plan, live view on your phone away from home is free and cloud history comes only with the plan.

How much detail will it capture, and how much will it cover?

At 4K 8MP there is enough detail to zoom into a recording and still read a face or a number plate, which is what matters after an incident.

Its horizontal field of view is 180°.

It records at 20 frames per second, smooth enough to follow a moving car.

How well does it see at night?

It can record in colour after dark by switching on its own spotlight, which also tends to move people on. Colour matters at night because clothing and car colours are often the details police ask for.

In full darkness it switches to infrared and records in black and white, with a stated range of 30 m (98 ft). Infrared bounces off glass, so do not mount it behind a window, and keep eaves and walls out of the edge of the frame.

Will it tell people apart from cars, animals and shadows?

Yes. It recognises people, vehicles and animals on the camera itself, so detection keeps working when the internet is down. That is the difference between a few useful alerts a day and dozens set off by trees, shadows and headlights.

Activity zones let you draw the areas it watches, so the street or a neighbour's yard does not set it off.

Two-way audio lets you speak to a visitor or a delivery driver from your phone.

How much storage does it need?

Recording around the clock at 4K 8MP and 20 fps with H.265 uses about 84.4GB a day. Motion-only recording, at a typical 30% of the day, cuts that to about 25.3GB.

On the largest card it takes (512GB), that is about 6 days of continuous recording or 20 days of motion clips before the oldest footage is overwritten.

On a recorder, four of these cameras kept for 30 days need about 9.9TB, so a 14TB drive with headroom.

Use a high-endurance card made for constant writing; ordinary cards wear out within months in a camera. The SanDisk High Endurance 128GB microSDXC Card ($36.99) fits.

What happens if the Wi-Fi or the power goes down?

If the internet goes down it keeps recording locally and keeps detecting people; you will not get phone alerts or remote viewing until the connection returns, and the footage is there when it does.

On Wi-Fi it also depends on your router: if the router loses power, the camera can still save to its card but cannot send anything.

In a power cut it stops recording, because it runs from mains power.

What do you need to install it?

It joins your Wi-Fi on 2.4/5 GHz. Check the signal at the mounting spot with your phone before you drill; a weak signal is the most common reason Wi-Fi cameras miss events.

It needs a power outlet within reach of its cable.

It is rated IP67: dust-tight and able to survive temporary immersion, so driving rain and snow are not a problem. It is rated to work from -10°C to 55°C (14°F to 131°F).

Does it work with an NVR, Blue Iris or Home Assistant?

Reolink says it records to Reolink's own recorders, such as the Reolink RLN8-410 8-Port PoE NVR ($189.99) and Reolink RLN36 36-Channel NVR ($220.99). A same-brand recorder keeps every feature, including smart alerts.

It offers an RTSP stream, so it can also feed software that accepts those, such as Blue Iris, Home Assistant or Synology Surveillance Station. Expect video and basic motion there; brand-specific smart alerts usually stay in Reolink's app.

Does it work with Alexa, Google Home or Apple Home?

Yes: Reolink lists Google Home support. That typically means live view on a smart display or TV and use in routines; recording and alerts still run through Reolink's own app. It is not listed for Apple Home, which matters if your household runs on iPhones and HomeKit.

What should you consider instead?

The Tapo C720 2K Floodlight Camera ($111.15) records at a lower 2K 4MP and costs $58.84 less.

The eufy Floodlight Camera E340 Dual Cam 3K Pan and Tilt ($219.00) costs $49.01 more.

The Arlo Pro 3 Floodlight Camera (Wireless Floodlight) ($149.99) records at a lower 2K 4MP, runs on battery with no wiring and costs $20.00 less.
