What we like
- 4K dual-lens camera with a wide 180° field of view — the highest resolution wire-free option here
- Solar panel included in this specific bundle, not sold as a separate accessory
- No subscription required — local storage via microSD or a Reolink Home Hub/NVR
Worth knowing

Our review
Two 4mm f/1.0 lenses stitched into one 5120×1440 picture give the Argus 4 Pro a 180-degree sweep from one battery camera, saved to a microSD card you own rather than a cloud you rent. What matters most is the 6W Solar Panel 2 in this bundle, which turns a battery Reolink rates at about two months into a camera you can leave alone. It suits a household that wants one wide view and no monthly bill.
What the numbers mean
Reolink's spec sheet gives 8 megapixels at 5120×1440 and 15 frames a second: two side-by-side images joined into one very wide frame, 180 degrees across and 50 top to bottom, rather than a single 3840×2160 television-style 4K picture. Reolink calls it 8 megapixels; the frame works out at about 7.4 million pixels against 8.3 million for 3840×2160, so the 4K label is generous. Behind the lenses is a 1/1.8-inch sensor at f/1.0, which Reolink says admits four times the light of an f/2.0 lens. There is no infrared mode: night footage is in colour through what Reolink calls ColorX, with five 2W, 6500K spotlights for when a garden is truly black. The housing is IP66, rated for -10°C to 55°C, 128 by 87 by 80 mm and 400 g, with dual-band Wi-Fi 6 and Bluetooth 5.0.
Battery and solar in a British garden
The 5000mAh battery is not removable. Reolink says it normally lasts about two months per charge when the camera records 300 seconds a day, warns at 10%, and that ten minutes of charging gives a day of power; charging is by USB-C from a 5V 2A charger. This bundle adds Reolink's 6W Solar Panel 2, which Reolink describes as a non-stop supply. Reolink gives no figure for the hours of sun it needs, and a north-facing wall in a British December is not where a 6W panel does its best work, so aim it south and keep daily recording time sensible. Battery life, in Reolink's words, varies with settings, usage and temperature, and -10°C is close enough to a hard frost to matter.
Storage, subscription and power cuts
Clips go to a microSD card of up to 512GB, Class 10 and FAT32; the box lists the camera, bracket, strap, mounting plate and cable, so buy the card. Reolink's Home Hub is supported for several cameras and RTSP, Reolink Cloud is optional in some countries, and the product page says no subscription fees are required. Detection is PIR to 10 metres across 170 degrees, with person, vehicle and animal recognition, adjustable zones and privacy masks. The siren and spotlights fire on motion by default and can be turned off, which neighbours will appreciate. Like every Wi-Fi camera it needs your router alive to reach your phone; a small battery from our router battery backup page covers a short cut.
How it compares
The Eufy SoloCam S340 takes the other approach: a 3K lens across 135 degrees plus a 2K telephoto for 8x hybrid zoom, with 8GB of storage inside and its own solar panel. The Reolink RLC-810A is the wired sibling: a true 3840×2160 at 25 frames a second, IP67, powered over Ethernet with no battery, if you can run a cable. TP-Link's Tapo C420S1 pairs a 2K camera with a hub for local recording. The Arlo Pro 5S covers 160 degrees in 2K but stores everything in a paid cloud. More on our security cameras page.
Living with it
The app runs on iOS, Android, Windows and Mac, supports twelve simultaneous streams and offers time-lapse video. Reolink's spec sheet lists Google Assistant and Alexa; two-way audio is built in. The warranty is two years, with 30-day money-back from Reolink's own store. The solar panel belongs to this bundle listing; the camera alone is battery only, so check the listing says Solar Panel 2 before you pay.
Our verdict
Buy it if one camera has to watch a whole frontage or back garden, you want footage on a card rather than a subscription, and you have a wall or post the panel can face south from. Skip it if you need to read a number plate at the far end of a long drive, where the Eufy's telephoto or the wired RLC-810A serve better, or if the camera will live where a panel never sees the sun and the battery becomes a monthly chore.

Who shouldn't buy this
Skip this if you'd rather have optical zoom on a single lens than a fixed dual-lens 180° view — the Eufy SoloCam S340 uses a wide-plus-telephoto pairing instead.
This is a Researched review: we haven't used this product. We check every specification against at least two independent sources, re-check the UK price on a schedule where we can track it automatically, and say plainly who it isn't for. Commissions never change a rating.

Does the Reolink Argus 4 Pro need a subscription?
No. It records to a microSD card of up to 512GB or to a Reolink Home Hub, and Reolink's page says no subscription fees are required. Reolink Cloud is an optional extra in selected countries.
How long does the Argus 4 Pro battery last?
Reolink says about two months per charge at 300 seconds of recording a day, and that ten minutes of charging powers it for 24 hours. The 6W Solar Panel 2 in this bundle is meant to keep it topped up, though Reolink gives no hours-of-sun figure.
Does the Argus 4 Pro have night vision?
In colour only. Reolink's spec sheet says infrared night vision is not supported; the f/1.0 lenses and ColorX processing work in low light, and five 2W, 6500K spotlights come on when it is dark.
Is the Reolink Argus 4 Pro really 4K?
It records 8 megapixels at 5120×1440 and 15 frames a second, two lenses stitched into one 180-degree frame: slightly fewer pixels than a 3840×2160 4K picture in a much wider shape, and a lower frame rate than the wired RLC-810A's 25.
Will the Argus 4 Pro cope with a British winter?
Reolink rates it IP66 and for -10°C to 55°C, so rain and frost are within range. It also says battery life varies with temperature, so expect shorter runs between charges in cold spells.
