Outdoor security cameras are the first line of defense for any home.

In this review, we'll dive deep into the eufyCam S4 (2 Pack) to see if it lives up to the hype. We'll explore its standout features, battery performance, and how it compares to its predecessor, the S3 Pro. By the end, you'll know if this is the right outdoor security camera for your home.

Key Features of the eufyCam S4

The eufyCam S4 is packed with features designed to keep your property safe. At its core, it offers 2K resolution video, which delivers crisp, clear footage even at night. The camera also boasts a 360° pan and tilt capability, allowing you to cover every corner of your yard with a single device. This is a significant upgrade over fixed cameras that require multiple units for full coverage.

One of the most impressive aspects of the S4 is its built-in AI. The camera can distinguish between humans, pets, and vehicles, reducing false alerts. You'll get smart notifications only when it matters, so you're not constantly bombarded with alerts from passing cars or swaying trees. Additionally, the S4 supports two-way audio, so you can communicate with visitors or scare off unwanted guests directly from your phone.

  • 360° pan and tilt for complete coverage
  • 2K resolution with color night vision
  • AI-powered human, pet, and vehicle detection
  • Two-way audio and siren for active deterrence

Battery Life and Power Management

Battery life is a critical factor for any wireless security camera, and the eufyCam S4 doesn't disappoint. With a large 10,000mAh battery, the S4 can last up to 6 months on a single charge, depending on usage. This means you won't have to worry about constantly recharging your cameras, making it a low-maintenance solution for outdoor security.

The S4 also features smart power management. When the camera detects motion, it activates and records; otherwise, it stays in a low-power standby mode. This intelligent system ensures that the battery is used efficiently, extending the time between charges. Additionally, the camera supports solar panel charging (sold separately), which can make it virtually maintenance-free if you have adequate sunlight.

  • Up to 6 months battery life on a single charge
  • Smart power management to conserve energy
  • Compatible with optional solar panels for continuous power

eufyCam S4 vs. S3 Pro: What's New?

If you're considering upgrading from the S3 Pro, you'll be pleased to know that the S4 brings several improvements. The most noticeable change is the addition of the pan and tilt feature, which was absent in the S3 Pro. This makes the S4 more versatile, as you can remotely adjust the camera's view to monitor different areas without physically repositioning it.

Another upgrade is the enhanced AI. While the S3 Pro had basic person detection, the S4's AI is more sophisticated, recognizing pets and vehicles with greater accuracy. The S4 also offers improved night vision, with color night vision that works in low light conditions, whereas the S3 Pro only provided black-and-white night footage. These enhancements make the S4 a compelling choice for those who want the latest in outdoor security technology.

  • Pan and tilt capability is new to the S4
  • Advanced AI recognizes humans, pets, and vehicles
  • Color night vision for clearer nighttime footage

The eufy Security app walks you through the process step by step, from connecting the camera to your Wi-Fi to positioning the pan and tilt range.

For more extensive storage, you can add a microSD card (up to 128GB) or connect to a HomeBase unit for centralized storage.

eufy also offers a cloud subscription service called eufy Cloud, which provides additional features like extended video history, AI recognition, and priority support. However, the camera works perfectly fine without a subscription, making it a budget-friendly option in the long run. This flexibility is a big plus for users who prefer to keep their data local.
