You’re probably looking at that empty corner in your living room or the hallway and thinking, "I just need a camera that works." No wires to pull through the attic. No batteries to charge every three months. Just something you can stick in an outlet and forget about.
Honestly, the eufy plug in camera lineup is basically the poster child for this "set it and forget it" vibe. But if you’ve spent any time on Reddit or deep-diving into security forums lately, you know it’s not always that simple. People buy these things thinking they’re getting a digital fortress, and then they realize they didn't even buy a microSD card.
Or worse, they find out their "privacy-first" camera was technically pinging a cloud server when they specifically told it not to.
The Reality of "No Monthly Fees"
Everyone buys eufy for the same reason: they're tired of being milked for $10 a month by Ring or Nest. It’s a compelling pitch. You buy the hardware, you own the footage. Basically, the eufy plug in camera stores your clips on a local microSD card (which you usually have to buy yourself, by the way) or a HomeBase 3 if you’ve got the full ecosystem.
But here’s the thing. If someone walks into your house and just... takes the camera? Your footage goes with them.

That’s the trade-off. Unless you have that HomeBase 3 (the S380) tucked away in a closet acting as a central brain, a standalone plug-in cam like the C120 or the C220 is a bit of a localized risk. You’ve got to decide if you’re okay with that "local only" life or if you actually want to pay for the eufy Cloud backup anyway, which sort of defeats the purpose of why most people switch to eufy in the first place.
The Model Soup Problem
Try searching for a eufy camera and you’ll get hit with a wall of numbers. C120, C24, P24, E220, S350. It’s a mess.
Let's clear the air. The Indoor Cam C120 (formerly the C24) is your basic, entry-level, stationary 2K camera. It doesn't move. It just stares. If you want something that follows your dog around the room, you’re looking at the E220 or the newer C220.
Then there’s the big dog: the Indoor Cam S350. This thing is overkill for most people, but it's cool. It has dual lenses—one wide-angle and one telephoto. It’s like having a security guard with binoculars. It does 4K resolution, which is great, but keep in mind that 4K video eats microSD cards for breakfast. If you’re recording 24/7 on a 128GB card in 4K, you’re going to loop over your footage much faster than you think.
Why 2.4GHz Wi-Fi is Still a Headache
It is 2026, and we are still struggling with 2.4GHz Wi-Fi requirements. Most eufy plug in camera models—especially the older or budget ones—refuse to talk to 5GHz networks.
You’ve probably got one of those fancy "Smart Wi-Fi" routers that merges both bands into one name. When you try to set up your eufy cam, it fails. Why? Because the camera is screaming for 2.4GHz and your phone is stubbornly sitting on 5GHz.

You usually have to go into your router settings, temporarily disable 5GHz, or move to the far edge of your backyard until your phone drops to the 2.4GHz band just to finish the pairing process. It’s annoying. Kinda feels like tech from 2015, but that’s the price of a cheaper chipset. The newer S350 actually supports dual-band Wi-Fi, which is a massive quality-of-life upgrade if you can swing the extra cost.
Privacy: The Elephant in the Room
We have to talk about the 2022/2023 controversy because it still colors how people see the brand. eufy claimed "local only" but was caught sending unencrypted thumbnails to the cloud so you could see them in your app notifications.
To their credit, they’ve gotten much more transparent. In 2025, they pushed out a bunch of updates and settlements (like the one with the NY Attorney General) that forced them to be crystal clear about when data leaves your house.

- Privacy Shield: Some models like the S350 now have a physical "privacy mode" where the lens literally rotates into the housing.
- Encryption: They’ve beefed up the end-to-end encryption for the web portal.
- On-Device AI: The BionicMind AI mostly happens on the camera or the HomeBase, not in a data center in another country.
Setting Up Your eufy Plug In Camera the Right Way
If you just took one out of the box, don't just stick it on a shelf.
First, get a High Endurance microSD card. Regular cards will die within months because security cameras are constantly writing and overwriting data. Look for cards labeled "High Endurance" or "Max Endurance" from brands like SanDisk or Samsung.
Second, check your placement. A eufy plug in camera pointed through a window at night is useless. The infrared (IR) lights will hit the glass, reflect back, and you’ll see nothing but a white glare. If you need to see outside, buy an actual outdoor camera or turn off the IR lights in the app and rely on external porch lights.
Third, tweak the motion zones. eufy’s AI is pretty good at "Human Detection," but it’s not perfect. If your camera is catching a ceiling fan or a swaying curtain, it’ll trigger 400 notifications a day and drive you crazy.
Actionable Next Steps
- Check your Bandwidth: If you plan on having four or five 2K cameras all streaming to your phone, make sure your upload speed can handle it. Most home internet is great at downloading but weak on uploading.
- Firmware First: The very first thing you should do after pairing is check for a firmware update. eufy pushes these out constantly to fix security vulnerabilities and improve AI accuracy.
- Hard Drive Upgrade: If you have a HomeBase 3, don't rely on the built-in 16GB. Pop a cheap 1TB SSD into the bottom of the unit. You'll get years of storage for less than the cost of a few months of a Nest subscription.
- Audit Your Notifications: Set the "Notification Scheme" to "Efficient" if you just want text, or "Full Effect" if you want the thumbnail preview (keeping in mind that the thumbnail technically hits the cloud briefly to reach your phone).
Ultimately, a eufy plug in camera is a tool. It’s arguably the best tool for people who hate subscriptions. Just don't expect it to be a magic wand that solves every security hole without a little bit of configuration and a decent SD card.
