eufy SoloCam E42 4K Solar Pan and Tilt Camera

Is the eufy SoloCam E42 worth buying?

The eufy SoloCam E42 4K Solar Pan and Tilt Camera is a solar-powered camera that records at 4K 8MP. It is best for outdoor spots with no power outlet, kept charged by sunlight.

What it does well: no subscription needed to record, 4K 8MP detail, person detection on the device and colour night vision. What to weigh up: event clips rather than 24/7 recording.

At $129.99 on Amazon today, it has a mid-range price: 2 of the 5 solar cameras we track cost less.

Does the eufy SoloCam E42 need a subscription?

No. It records to a microSD card, a recorder or Eufy's hub with no monthly fee; eufy Security Cloud Backup Basic Plan (from $3.99 a month) 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.

If you do add the plan, three years comes to about $273.63 including the hardware; without it, the $129.99 you pay today is the whole cost.

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. 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 and vehicles 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.

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

How much storage does it need?

Battery cameras record short clips, not continuous video, so storage goes a long way. At 4K 8MP, 50 clips of 20 seconds a day come to about 0.7GB a day.

A 128GB microSD card, the largest it takes, would hold roughly 174 days of that, so the card size matters less than its endurance rating.

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 the camera itself keeps running on its battery, but your router does not unless it has backup power.

What do you need to install it?

It joins your Wi-Fi. 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.

There is no wiring: it runs on a rechargeable battery and wakes to record a clip when it senses motion. That makes it quick to fit anywhere, but it does not record around the clock. Solar charging keeps the battery topped up where the panel gets a few hours of direct sun a day.

It is rated IP65: dust-tight and protected against water jets.

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

Eufy says it records to Eufy's own recorders, such as the eufy HomeBase S380 (HomeBase 3) ($139.99). A same-brand recorder keeps every feature, including smart alerts.

Eufy does not state RTSP or ONVIF support for it, so do not count on third-party recorders or software.

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

Yes: Eufy lists Amazon Alexa, Apple Home (HomeKit) and Google Home support. That typically means live view on a smart display or TV and use in routines; recording and alerts still run through Eufy's own app.

What should you consider instead?

The eufy eufyCam S330 (eufyCam 3) 4K Solar Add-on Camera ($149.99) costs $20.00 more.

The Reolink Argus Solar 5MP Dual-Band Wi-Fi 6 Battery Camera with Built-in Solar Panel ($99.99) costs $30.00 less.

The UniFi G5 Bullet 2K PoE Camera ($162.01) runs on one PoE cable and costs $32.02 more.

Each is listed with its live price and Security Fit in Alternatives above. If event clips rather than 24/7 recording is a deal-breaker, the first of those is where to look.
