Eufy SoloCam S340 vs S4 – Check Which One Is Best & Why?

EufyCam S4 & Eufy SoloCam S340 Plus share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the EufyCam S4 rather than the Eufy SoloCam S340 Plus.

Why Do I Recommend The EufyCam S4?

  • The Eufy S4 has a 4K fixed bullet camera for capturing finer facial and license plate details at longer distances, while the Eufy SoloCam S340 uses a 3K wide camera.
  • he Eufy S4 includes a dual-camera hybrid design with a fixed lens and a PTZ lens for maintaining constant wide coverage while actively tracking subjects, whereas the Eufy SoloCam S340 relies on a single PTZ camera.
  • It supports radar plus PIR motion sensing for more precise movement detection and reduced false alerts from environmental motion, while the Eufy SoloCam S340 uses PIR-based detection only.
  • The Eufy S4 supports bullet-to-PTZ coordinated tracking to keep moving subjects continuously centered even when they change direction, whereas the Eufy SoloCam S340 performs standard pan-and-tilt tracking only.
  • Eufy S4 comes with higher onboard local storage capacity for retaining more video history without overwriting important events quickly, while the Eufy SoloCam S340 has smaller built-in storage.
  • It supports 24/7 continuous recording when connected to constant power for uninterrupted surveillance of critical areas, while the Eufy SoloCam S340 records events only due to its battery-based design.
  • The Eufy S4 includes a higher-output solar panel for faster recharging and more reliable long-term operation in low-sun conditions, whereas the Eufy SoloCam S340 uses a lower-wattage solar panel.
  • Eufy S4 features a removable high-capacity battery pack for quicker maintenance and reduced downtime during extended use, while the Eufy SoloCam S340 has a non-removable internal battery.

Maybe the Eufy SoloCam S340 Plus can make you comfortable because it’s a little bit cheaper than the EufyCam S4. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.

What Common Both Can Do?

  • Outdoor security camera: Both models are designed specifically for outdoor surveillance, allowing them to monitor entrances, yards, and perimeters. This ensures reliable operation in exposed environments.
  • Wireless installation: Each camera operates without wired data connections, making placement flexible. This simplifies setup and allows installation in locations without nearby outlets.
  • Battery-powered operation: Both cameras rely on internal rechargeable batteries. This allows continued operation during power outages and reduces dependence on fixed wiring.
  • Solar charging support: Each model supports solar panels for continuous recharging. This helps extend runtime and minimizes the need for manual battery recharging.
  • Pan-and-tilt capability: Both cameras can pan horizontally and tilt vertically. This enables wider area coverage compared to fixed-lens cameras.
  • AI motion detection: Each device uses AI-based detection to analyze motion events. This helps reduce unnecessary alerts from non-relevant movement.
  • Human detection: Both cameras can identify people specifically. This improves alert relevance and helps users focus on meaningful security events.
  • Vehicle detection: Each model supports vehicle recognition. This is useful for monitoring driveways or street-facing areas.
  • Local video storage: Both store recordings locally rather than relying solely on cloud storage. This improves privacy and allows access without ongoing fees.
  • Subscription-free recording: Neither camera requires a paid subscription for basic recording features. This reduces long-term ownership costs.
  • Full-color night vision: Both models use integrated lighting to capture color video at night. This improves detail recognition compared to black-and-white footage.
  • Infrared night vision: Each camera also supports infrared night vision when lighting conditions require it. This ensures nighttime visibility without visible light.
  • Two-way audio: Both cameras include microphones and speakers for two-way communication. This allows users to speak to visitors or deter intruders remotely.
  • Built-in spotlight: Each device includes an integrated spotlight. This enhances night visibility and can act as a visual deterrent.
  • Built-in siren: Both models feature an onboard siren. This allows audible deterrence when suspicious activity is detected.
  • Weather-resistant design: Each camera is built to withstand outdoor weather conditions. This ensures reliable performance in rain, heat, and cold.
  • Wi-Fi connectivity: Both cameras connect via 2.4 GHz Wi-Fi. This provides stable connectivity over longer distances common in outdoor installations.
  • Eufy Security app support: Both models are managed through the Eufy Security app. This enables unified control, live viewing, and alert management.
  • Smart alerts: Each camera sends real-time alerts to connected devices. This allows users to respond quickly to detected activity.
