- eufy Baby Monitor E21 is $259.99 at eufy and Target, about $180 on Amazon: a 4K pan-tilt camera, a 5" parent screen, an 800–1,000 ft (240–300 m) direct link with no Wi-Fi, plus an app when you want it. Two-way audio, temperature, cry and noise alerts, 24/7 recording in the app.
- eufy Baby Monitor C10 is $99.99 on sale ($129.99 list): 2K camera, 351° pan, up to 12 hours of screen time, an SD card slot for local recordings, the same hybrid Wi-Fi-or-not design.
- The SpaceView, eufy's long-time US favorite, is no longer on eufy's baby-monitor page. If you own one, it keeps working; if you're shopping, the C10 and E21 are what eufy sells now.
- Mamoon costs $0 in hardware if you have an old phone (or about $25–35 for a Tapo camera with night vision), then $3.99 a month or $24.99 a year after 30 free days. It tells a cry from other noise on the phone, alerts you with the sound muted, and never touches a cloud.
- Buy eufy if you want a screen that isn't your phone and range beyond Wi-Fi. Try Mamoon if you want to be woken by crying, not by every sound, and would rather not buy another device.

Prices checked on September 29, 2026 at eufy.com, Target and Babylist (Amazon price as Babylist listed it in June 2026); see sources. eufy's own pages don't state the C10's screen size or lullabies for either model, so those cells say so rather than guess.
Is a dedicated screen better than a phone?
At 3 a.m., often yes. The eufy monitor sits on the nightstand, shows the crib the moment you glance at it, and never asks you to unlock anything. It doesn't ring, and a grandparent can use it without an app. That is the honest case for eufy, and the C10 at $99.99 is a lot of monitor for the money. The E21 adds a 4K camera with a battery, so the camera itself can move to the living room or a hotel.
Mamoon's answer is that the phone you carry anyway is already a better screen: bigger, sharper, and in your pocket in the yard. It has a Night mode that turns the screen black at 1% brightness and brightens slightly only when the baby cries, and it shows how many hours the baby phone's battery has left. Several parents can watch at once from their own phones, each with their own alert settings.
Who hears the difference between crying and a truck outside?
Both eufy monitors have cry detection, and eufy lets you set its sensitivity in five steps and space out notifications. The parent unit, though, is at heart a speaker: on the screen you hear the room, and the E21's noise reduction (eufy quotes 20 dB) quiets the background rather than deciding what matters.
Mamoon runs a sound classifier on the phone itself. It sorts the night into Calm, Stirring and Crying, and you choose whether to be woken for Only crying, Crying and fussing or Every sound. A dog, a door or the TV count as Stirring, not a cry. The alert arrives even with the nursery sound muted and the screen locked, so you can sleep in silence and still be woken by the one sound that matters. In the morning, the overview shows the whole night on one line with a picture from every sound, which is a smaller thing than eufy's 24/7 recording but usually the thing you actually wanted to know. How this works in detail is in how baby cry detection works.
Wi-Fi off, Wi-Fi on, and who sees the video
eufy's hybrid design is genuinely clever. Flip the Wi-Fi switch off on the E21 and the camera talks only to the monitor; flip it on and you can watch in the eufy Baby app from work, share with up to five family members, and record around the clock. The app needs an eufy account, and eufy says video is encrypted and stored locally; the App Store rates the app 4.7 from about 9,300 reviews, while Babylist calls the app experience "less polished" than dedicated Wi-Fi monitors.
Mamoon has one mode: the video goes from the camera to your phone over your home Wi-Fi, with no account and no server, and it keeps working when the internet is down. Away from home you connect through the free Tailscale VPN instead of a cloud. If you'd rather never create an account for your nursery, that is the shorter list of things to trust.
What it costs over two years
An E21 is $259.99 once (or about $180 if Amazon's price holds), a C10 about $100 to $130, and eufy lists no subscription for either. Mamoon is $24.99 a year, so about $50 over two years, plus a camera only if you don't have an old phone: a TP-Link Tapo C200 with infrared night vision runs $25–35. That makes Mamoon roughly $50–85 for two years against $100–260 for eufy, but a one-time purchase catches up if you use it for a second child. The full picture, with fifteen monitors and apps on one dated table, is in what a baby monitor really costs.
What happened to the eufy SpaceView?
The SpaceView and SpaceView Pro were the non-Wi-Fi monitors everyone recommended for years. As of September 29, 2026, neither appears on eufy's baby-monitor page or in Target's eufy listings; the lineup is the C10, the E21 and add-on cameras for each. If yours still works, there is no reason to replace it. If you're searching for a "SpaceView alternative", the C10 is the closest in spirit (screen plus camera, no cloud required), and Mamoon is the alternative that costs nothing up front. eufy's own FAQ also still describes the older E110, with a 5" display, 720p video and a 460–600 ft range.
When eufy is the better buy
- You want a screen on the nightstand that is not your phone and that a babysitter or grandparent can pick up without an app.
- You need range beyond your Wi-Fi, or a camera with its own battery for travel.
- You want two-way talk, room temperature, twins on one split screen, or a full night of video to scroll back through.
- You'd rather pay once than subscribe.
When Mamoon is
- You have an old phone in a drawer, or a Tapo, Hikvision or Dahua camera already, and don't want to buy another device.
- You want to sleep with the sound off and be woken by crying, not by every rustle.
- You don't want an account or a company's server anywhere near the nursery video.
- You like a morning overview more than 24 hours of footage, and a night mode that keeps the bedroom dark.

Frequently asked questions
Does the eufy baby monitor need Wi-Fi?
No. Both the E21 and the C10 connect the camera straight to the parent screen; the E21 has a physical Wi-Fi switch and the C10 turns Wi-Fi off with one tap in the app. Wi-Fi is only for watching in the eufy Baby app, sharing with family and, on the E21, recording. Mamoon needs your home Wi-Fi (a router without internet is enough); it doesn't need a cloud.
Does eufy have a subscription?
eufy lists no subscription for either monitor. The E21 records 24/7 in the app and the C10 records to an SD card you buy. Mamoon is the one with a subscription: $3.99 a month or $24.99 a year after 30 free days, paid by the watching phone only.
Is the eufy SpaceView still sold?
It no longer appears on eufy's baby-monitor page or at Target as of September 29, 2026. eufy's current models are the C10 and E21. An existing SpaceView keeps working on its own.
Can I use my eufy security camera with Mamoon?
Only for the picture. eufy's indoor cameras stream RTSP video but with AAC audio, which Mamoon can't play, so it can't listen for crying unless you run go2rtc to convert the sound. A Tapo, Hikvision or Dahua camera works with sound out of the box.
Does Mamoon have two-way talk or lullabies like eufy?
No. Mamoon does video, sound and cry detection, and stops there. If talking to the baby through the camera matters to you, the E21 has two-way audio.
Which one wakes me only when the baby actually cries?
eufy alerts you to crying and loud noise with adjustable sensitivity. Mamoon goes a step further: it classifies each sound on the phone as Calm, Stirring or Crying, and you can ask to be woken for crying only, with everything else waiting in the morning overview.
