eufy Security eufyCam E40 Add-On Camera Overview

Add the eufyCam E40 2K Add-On Solar-Powered Camera from eufy Security to a camera kit that includes a HomeBase 2 or HomeBase S380 base station. This camera features a built-in solar panel for continuous solar power, three night vision modes (standard, spotlight, IR), two-way audio thanks to a built-in speaker and microphone, and no monthly fees.
Capture 2K Resolution Video with Night Vision
This add-on camera captures 2K resolution video 24/7. IR LEDs provide night vision functionality, while spotlights and MaxColor Vision technology provide illumination for recording full color video, along with deterrence of unwanted activity. The camera's 2.8mm fixed lens delivers a 130° 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.

Continuous Solar Charging
Powered by SolarPlus 2.0 technology, the eufyCam E40 Pro features a built-in solar panel for continuous power. Just two hours 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 Details
  • IP66-rated enclosure for safe outdoor use
  • Camera's enclosure features coating that resists UV damage
  • 105 dB siren to deter unwanted activity
  • PIR motion detection

Eufy E40 add on cameras for the back yard

By Rafael
Rated 5 out of 5
Date: 2026-04-26

Current owner of the Eufy video door bell, home base 2, expanded into the Eufy ecosystem by adding 2 additional cameras for the back yard. Easy to install and add to the home base. Pleased with the 2K resolution, don't need the ninth degree of detasil for my situation. Overall, very pleased with the purchase.

Please note that the eufy Security E40 2K Solar-Powered Battery Add-On Camera does support and work with Apple HomeKit. But this camera model would also require that you have the Eufy HomeBase 2 or HomeBase S380 to operate. Add this: eufy Security S380 HomeBase 3 BH # EUT80301D1
