Eufy SoloCam E42 Review: A 4K Solar Pan-Tilt Camera That Tracks Well and Skips the Monthly Fee
The Eufy SoloCam E42 is a wire-free 4K outdoor camera with 360° pan, AI tracking of people and vehicles, color night vision and a solar panel that owners say keeps the battery charged even in partial shade or cloudy weather. It records to a microSD card with no monthly fee, since eufy offers no cloud storage for it, and owners consistently praise the easy setup and the clear image. The trade-offs are motion clips that can end too soon, occasional missed detections and slow tracking, a weak microphone, and extras such as face recognition, pet detection, an RTSP stream and hard-drive storage that only arrive with a HomeBase S380. For a home that wants subscription-free 4K coverage without running cables, it is a strong value.

Who is the Eufy SoloCam E42 for?
The SoloCam E42 is an outdoor security camera for people who want high resolution and wide coverage without wiring or a subscription. It records 4K video (3840x2160, 16:9) through a 130-degree lens, pans a full 360 degrees and tilts 70 degrees, and its AI follows people and vehicles as they move. A built-in spotlight adds color night vision next to infrared black-and-white night vision, and a strobe light, a siren and two-way audio help deter intruders. It is rated IP65 and runs on a rechargeable battery topped up by its solar panel; eufy estimates about 90 days per charge at 300 seconds of recording a day, and plugging it into USB-C power unlocks 24/7 recording. Footage goes to a microSD card of up to 128GB, which is not included, because the camera has no built-in storage and no cloud option. It connects over 2.4GHz Wi-Fi on its own, or to a HomeBase S380, which adds face recognition, pet detection, an RTSP stream and up to 16TB of storage with a hard drive. It works with Alexa, Google Home, Apple HomeKit and Home Assistant (through the eufy Security community integration).
What buyers love
Easy installation is the most common theme: owners describe mounting and app setup as quick and straightforward, including one who put up six cameras around a house on their own. Image quality comes next, with the 4K picture called clear by day and by night and the zoom useful for picking out detail. The solar panel earns steady praise, with owners reporting that the battery stays charged in cloudy weather and even on a camera near a tree that rarely gets direct sun, in a full-surveillance recording mode. The automatic tracking and the pan and tilt control are liked for covering an outdoor space, one owner appreciates the wide range of sensitivity and video quality settings, and another notes that motion can pop the live view up on an Amazon Echo automatically. Keeping footage local with no monthly fee is a recurring reason to buy, and several owners call it very good value against competing cameras.
What to know before you buy
Motion recording is the main source of criticism. One owner finds the clips too short to catch what happens before and after an event, even after changing the settings, and another reports occasional missed detections, especially when several people arrive at once, plus tracking that can lag. One owner found programming the AI detection confusing because the camera stays pointed where tracking ended instead of returning to its start position, and a critical review describes a slow app, missed motion and 4K detail that only holds up in good conditions. The microphone picks up little unless the speaker is close, and one owner finds the night image weaker than on a fixed eufy camera they own and puts the reach to a HomeBase S380 at about 30 meters. On the spec sheet, the camera has no built-in storage and no cloud backup, so budget for a microSD card, and face recognition, pet detection and the RTSP stream all require a HomeBase S380. It connects only to 2.4GHz Wi-Fi, has no HDR, and does not support SmartThings or Matter.
Is the Eufy SoloCam E42 worth it?
For a wire-free outdoor camera, the SoloCam E42 packs a lot in: 4K video, full 360-degree coverage with tracking, color night vision, a siren and solar charging that owners find reliable, all without a monthly fee. Most owners are clearly happy with it. It is weaker where detection has to be precise, since short clips, the odd missed event and slow tracking come up in a few reviews, and the smartest features depend on a HomeBase S380. If you want subscription-free 4K coverage of a yard or driveway and are fine adding a microSD card (or a HomeBase for the extras), it is a strong value. If you need every event captured in full, a wired camera with continuous recording is the safer choice, which the E42 can also become once it is plugged into USB-C power.
Frequently asked questions
Does the Eufy SoloCam E42 need a subscription?
No. It records to a microSD card of up to 128GB with no monthly fee, and eufy does not offer cloud storage for it. The card is not included. Pairing it with a HomeBase S380 adds up to 16TB of storage with a hard drive.
Does the SoloCam E42 need a HomeBase?
No. It works on its own over 2.4GHz Wi-Fi. A HomeBase S380 is optional and adds face recognition, pet detection, an RTSP stream for NAS recording and hard-drive storage.
Can the SoloCam E42 record 24/7?
Yes, when it is wired to power. eufy requires a direct USB-C power supply plus a microSD card, or a HomeBase with a hard drive, for continuous recording. On battery it records motion events.
Does the SoloCam E42 support RTSP?
Through a HomeBase S380. That is where the E42 RTSP stream, which is also how eufy cameras record to a NAS, is served from, so plan on the HomeBase if you want to feed the camera to a NAS or another video app.
Which smart home platforms does the SoloCam E42 work with?
It works with Alexa, Google Home and Apple HomeKit, and with Home Assistant through the eufy Security community integration. It does not support SmartThings or Matter.
How long does the battery last?
eufy estimates about 90 days per charge based on 300 seconds of recording a day, and the solar panel keeps topping it up. Owners report the battery staying charged even in cloudy weather or partial shade.
