Community Reviews

The eufy S4 eufyCam stands out as a solar powered wireless security camera with sharp day and night video, strong detail capture, and easy battery access. The solar panel is described as keeping it charged even through Illinois winter, and the camera has held up for months without issues after replacing an S340 that dropped Wi Fi. The main questions are around its true rotation range, mounting compatibility with older brackets, and whether wireless security or cloud dependence matters for your setup. It looks like a capable outdoor camera with practical power and image quality.

Common Questions (5)

  • It is not beholden to eufy cloud. RTSP support is still an open question in the comments, so that specific streaming option is not confirmed here.

  • Yes. The solar panel can keep the battery charged even through winter, including in Illinois. It also has a replaceable battery with easy access if you ever need to swap it out.

  • Yes. It captures a lot of detail and is described as having very good day and night image quality, while the solar panel keeps the battery fully charged.

  • Yes. It can be used to set off a siren and help give you time to call the cops, making it more of a deterrent/response tool than a physical barrier.

  • That is not confirmed in the comments. The question is whether the S4 bracket hole locations match the S340 so existing brick-wall holes can be reused, but no answer is provided here.

I've been looking at wireless for a while, and although they seem fine for casual monitoring, but if you're going to be seriously bulgraized aren't they going to jam the wireless cams with a broadband transmitter? Anyone know if this will put out and rtsp stream or are you beholden to their cloud instance?
It's so insanely rare for jammers to be used. If someone seriously wants to rob your home they're going to hit the camera with a bat from the side and walk in. A camera won't stop them regardless of wireless or wired.

Thieves don't even care about cameras anymore. Just put on a mask and they keep it moving.

Yup. But it gives you a chance to set off a siren and/or call the cops.

No, that bracket is different
What about the bracket holes location? Are those the same? I had to drill the holes in the brick wall for s340 mount, can I reuse the existing holes?

Tru dat.

A rather high profile kidnapping case from a few weeks ago, where the perp had on a mask on camera, still has not been solved.

If we get one s4 camera, I'm sure it will provide a better quality video when we want to check on the chickens, but if we get the two s340 cameras, we could either buy one at a time to save up front, or buy two to have batter coverage of both sides of the house.

Does one have a better mic/speaker than the other?

Too expensive for my needs, but knowing Eufy, this thing will drop significantly in price.
