Compare the eufy SoloCam E30 and SoloCam S340 on field of view, tracking, and solar power to decide which wireless outdoor camera fits your home.
Quick answer
Choose the eufy SoloCam S340 if you want a single camera with dual-lens 3K clarity, 8× zoom, and a 360° view for wide areas. Choose the eufy SoloCam E30 if you need AI auto-lock tracking and 360° pan in a compact solar camera, or if you want it bundled with a HomeBase S380 and Video Doorbell E340 for a complete system. Neither requires a subscription for core recording.
Field of view and tracking: what each camera actually covers
The SoloCam S340 pairs an upper wide-angle lens with a lower PTZ lens to deliver a 360° guardian view with no blind spots, plus 8× zoom to inspect details up to 40 ft (12 m) away. The SoloCam E30 also provides 360° pan coverage, but its standout is AI Auto Lock and Tracking: when it detects a human or vehicle, it locks on and records their movement across the scene. If you mainly want to monitor a wide yard or driveway and zoom in on distant details, the S340’s dual-camera design is more flexible. If you care most about following a person or car as they move through the frame, the E30’s tracking is the more direct fit.
Power and placement: solar behavior and installation realities
Both cameras are solar-powered, but the details differ. The SoloCam S340 uses a removable solar panel and is designed to install once and run continuously, so you can position the panel for best sun exposure. The SoloCam E30 also relies on a removable solar panel for Forever Power, which helps on cloudy days or shaded mounting spots. In practice, the S340’s dual-lens body may need a bit more clearance to aim both lenses, while the E30’s single-lens pan design is simpler to angle. Neither camera includes a subscription for basic motion recording, so local storage or a HomeBase (if bundled) handles your footage.
System fit: standalone camera vs bundle value
The SoloCam S340 is sold as a standalone camera, which makes it a straightforward add-on if you already have a HomeBase or just want one more viewpoint. The SoloCam E30 is available in a bundle with the HomeBase S380 and Video Doorbell E340 (Battery Powered), giving you a coordinated setup for front-door and yard coverage in one purchase. If you are building a system from scratch and want doorbell plus camera coverage, the bundle reduces the number of separate decisions. If you only need one camera to fill a gap, the standalone S340 keeps things simple.
Trade-offs to weigh before you buy
- S340: dual-lens flexibility vs. larger body: The S340’s dual-camera design delivers 3K clarity and 8× zoom, but its wider housing may need more mounting space and careful aiming to avoid obstruction. Best if you want zoom and a wide view from one camera and have room to mount it.
- E30: AI tracking vs. single-lens zoom limits: The E30 follows humans and vehicles with AI Auto Lock and Tracking, but it does not offer the S340’s 8× zoom or dual-lens 3K detail. Best if tracking movement matters more than zooming in on far-away details.
- Bundle vs. standalone: convenience vs. cost control: The E30 bundle includes a HomeBase S380 and Video Doorbell E340, which adds upfront cost but covers door and yard in one package. The S340 is a single camera, so you only pay for what you need now. Choose the bundle for a full starter system; choose the S340 to expand an existing setup.
