eufy Security eufyCam S3 Pro 4K UHD Outdoor Add-On Wireless Security Camera
Add the eufyCam S3 Pro 4K UHD Outdoor Add-On Wireless Security Camera from eufy Security to a camera kit that includes a HomeBase 3 base station. The camera kit provides an indoor/outdoor surveillance monitoring solution for your home.
Capture 4K UHD Resolution Video
This add-on camera uses a 1/1.8" CMOS sensor that captures 4K UHD resolution video at 15 fps. Four IR LEDs provide up to 33' of night vision, while adaptive spotlights provide illumination for recording full color video, along with deterrence of unwanted activity. The camera's fixed lens delivers a 135° angle of view.

Remote management is possible via the eufy Security app for iOS and Android. Compatibility with Amazon Alexa, Google Assistant, and Siri enables seamless voice commands. The camera is housed in an IP67-rated enclosure for safe outdoor use.

Continuous Solar Charging
Powered by SolarPlus 2.0 technology, the eufyCam S3 Pro features a built-in solar panel for continuous power. Just an hour of sunlight will keep the camera fully charged around the clock. An internal rechargeable battery offers back up power. The battery will deliver power for up to a year on a full charge.

An external solar panel (available separately) can be added to expand your energy coverage. External solar panels come in handy for areas that receive insufficient sunlight, like under an eave or a gutter, ensuring that the camera will still be able to get solar power while not receiving ideal direct sunlight.

Additional Features
  • 2.4 GHz Wi-Fi connectivity
  • Built-in speaker and microphone with noise reduction
  • 100 dB siren to deter unwanted activity
  • 24/7 snapshot for monitoring daily activities
  • Radar and PIR motion detection
  • Radar-powered motion detection range up to 40'
  • Self-learning AI (BionicMind) provides facial recognition, human detection, vehicle detection, and pet detection

eufy Security EufyCam S3 Pro Reviews

Perfect  camera to observe Wildlife

By Arda
Rated 5 out of 5
Date: 2025-07-23

We live in an area with lots of wildlife and for years have been using trail cameras like the ones from Bushnell. However, having to use batteries was a nuisance and quality of photos and/or video was mediocre at best. Now we have installed these security cameras and WOW . The quality of the life feed, photos and videos is amazing ! And the field of view is much better than any train; camera. Plus you can see it all on your phone, plus it is super easy to install. Price may be slightly higher but soooo worth it !
