eufy Multi-Cam Kits: SoloCam vs eufyCam Systems

Best for
Dual-lens zoom on driveways

Best for
4K detail with pan-tilt tracking

The eufy Security SoloCam E42 4-Cam Kit gives you four true 4K UHD solar cameras. eufy says the resolution is sharp enough to recognize license plates up to 33 feet away. Each camera offers 360° pan and tilt, and built-in AI detects and automatically tracks people and vehicles to reduce false alarms.

SolarPlus 2.0 is rated to keep each camera charged with just 2 hours of direct sunlight a day, and the battery is listed at 55.98 watt-hours. Each camera supports microSD up to 128 GB (card not included), and the kit includes a HomeBase 3 with 16 GB of built-in storage, expandable up to 16 TB, supporting continuous recording even during network outages. A motion-activated strobe light and siren help deter visitors, and it works with Alexa.

This kit suits enthusiasts who want 4K detail and moving cameras without the complexity of dual-lens hardware. If you want a fixed wide view plus a PTZ lens on each unit, the eufyCam S4 goes further.

• True 4K UHD, plates readable to 33 ft
• 360° pan and tilt with AI tracking
• SolarPlus 2.0, 2 hours of sun daily
• HomeBase 3, expandable to 16 TB

Best for
Two-camera starter with HomeKit

Best for
Budget-minded 360° auto tracking

Best for
Maximum coverage and cross-camera tracking

The eufy Security eufyCam S4 4-Cam Kit uses a triple-lens design: an upper 4K bullet lens with a 130° wide view and a lower 2K PTZ lens, so each camera does the work of two. AI locks onto and auto-frames multiple subjects and zooms for detail up to 164 feet away, with 8x hybrid zoom listed in the specs.

The HomeBase S380 links all four cameras for true cross-camera tracking, following a person as they move from one camera’s view to the next. It stores footage locally on a 16GB built-in drive, expandable with any 2.5-inch drive, and runs local BionicMind AI. A 5.5W solar panel with SolarPlus 2.0 needs just 1 hour of direct sun daily. Radar and PIR sensors reduce false alerts, and red and blue lights plus a 105 dB siren deter intruders. Specs also list starlight color night vision and 24/7 smart snapshots.

This is the enthusiast pick for large properties where tracking across cameras matters. It is overkill for a small yard, where the C37 or E40 does the job. For more on how these hubs tie a setup together, see our eufy security camera system guide.

• 4K bullet lens plus 2K PTZ lens
• Cross-camera tracking via HomeBase S380
• Radar and PIR detection, 105 dB siren
• 5.5W solar panel, 1 hour of sun daily

The eufy Security eufyCam C37 4-Cam Kit brings 360° pan and tilt with auto tracking to four 2K cameras. eufy states 2K delivers 77% more pixels than 1080p, and a built-in spotlight provides color night vision for faces, plates and clothing in darkness.

The kit uses a HomeBase Mini with 64GB of built-in storage, expandable to 1TB with microSD (sold separately). Through the HomeBase Mini, you get human, vehicle, pet and facial recognition, cross-camera tracking and support for up to 10 cameras in one app. Each camera has a detachable 3W solar panel you can angle for sun independently of where the camera points. It is rated IP65 and mounts on walls or ceilings.

Compatibility matters here: the C37 is not compatible with HomeBase 2 or HomeKit, and it needs HomeBase 3 or HomeBase Mini firmware at or above the listed versions. This kit suits buyers who want tracking and facial recognition and can live with 2K rather than 4K.

The eufy Security SoloCam S340 4-Cam Kit uses 3K dual-lens cameras with 8x zoom and clear detail up to 40 feet. Installed vertically, each camera offers 360° pan and tilt to cover the porch, backyard and driveway.

Each camera has a removable solar panel, and eufy advertises a 7-minute wire-free install. The listing promises local storage with no monthly fee but does not specify capacity, whether a HomeBase is included, or whether it uses microSD. The model name reads “SoloCam S340 4+1”, which may suggest an extra component, but the listing does not say what it is.

This kit suits readers who want zoom for spotting details at the edge of the driveway. If you need clear storage specs, the E42 and C37 listings spell them out. Our eufy outdoor security cameras roundup covers single-camera options too.

The eufy Security eufyCam E40 2-Cam Kit is the smallest kit here, with two 2K (4MP) cameras. Its MaxColor night vision uses an F/1.0 aperture for full-color footage in near-darkness without harsh spotlights.

A built-in solar panel works with a 13,000 mAh battery, and USB charging serves as backup. The kit includes a HomeBase 2 with 16 GB of local storage and no subscription. An upgraded PIR sensor with person, pet and vehicle detection reduces false alerts, and setup is described as a 10-minute, two-screw job. It is the only kit here that lists Apple HomeKit, along with Alexa and Google Assistant.

This suits renters or smaller homes that need a front door and backyard covered, especially in an Apple household. It does not pan or tilt, so coverage depends on placement.

• 2K MaxColor night vision, F/1.0
• Solar plus 13,000 mAh battery
• HomeBase 2 with 16 GB
• HomeKit, Alexa and Google Assistant
