By Graham FisherVerdict: The eufy Baby Monitor E21 is a reasonable pick for parents who want a straightforward video monitor from a established consumer electronics brand, at a price point that is usually lower than premium camera systems. It suits a single-caregiver household, a nursery that is not too large, and buyers who are comfortable with basic app setup. Skip it if you need advanced sleep analytics, a long-range multi-room system, or documented answers to every privacy question before you buy, since you will want to confirm those details on the manufacturer’s current listing.
Before you buy, check the current price and included accessories directly. Check price on Amazon pricing and bundles change, so use the listing as your final reference.
eufy Baby Monitor E21 at a Glance
This review is based on the manufacturer’s published information, the product listing, and patterns in owner feedback on retail sites and forums. We did not run the monitor through lab tests, and we are not reporting results from long-term personal use. Where a spec was not clearly documented in sources we could check, we left it out rather than guess.
| Specification | What to know |
|---|---|
| Brand | eufy, a consumer electronics brand that sells under the Anker umbrella |
| Product type | Video baby monitor with a camera unit and a parent unit |
| Primary use | Visual and audio monitoring of an infant in a nursery or bedroom |
| Setup approach | Camera and parent unit pairing, with optional app features depending on the model configuration |
| Verify before buying | Resolution, screen size, battery runtime, connection type (local or app-based), and warranty length, all listed on the current manufacturer page |
Some buyers want exact numbers on night vision range, viewing angle, and parent-unit battery life. Those figures vary by listing version and region, so we have not repeated them here. If a number matters to your decision, compare it against the spec sheet you see at checkout.
Design and Build
The camera unit is compact and fits the common design pattern of this category: a small body with a lens, a mounting base or stand, and a power cable. Owners generally describe the camera as unobtrusive on a shelf or dresser. The parent unit is a handheld screen with physical controls for volume and talk functions, which many parents prefer over touchscreen-only designs at night because it is easier to operate without looking.
Build quality reviews are mostly positive for everyday use. Owners often mention that the plastic housings feel sturdy enough for a nursery environment, though a few note that the mounting hardware needs careful tightening. A loose camera mount is a real concern in a crib-adjacent room, so check it after installation and again after a few weeks.
Placement matters more than most product features. Keep the camera and any cord well away from the crib, and follow the manufacturer’s stated distance guidance. The American Academy of Pediatrics recommends keeping cords out of reach of infants, and you should position the camera so it cannot be pulled into the crib. For more detail, read our guide to Baby Monitor Placement and Cord Safety.
Performance
Video performance is the main question for most buyers, and it is also where reviews tend to be most mixed. Owners who report good results usually describe clear daytime images and workable night vision in a dim room. Owners who report problems often mention graininess in very low light, reduced clarity at longer distances, or a lag between motion and what appears on the parent screen.
Audio is generally described as adequate for hearing a baby breathe, fuss, or cry. Parents who want to hear soft sounds across a larger home may find the audio range limited, especially if there are thick walls between rooms. If you live in a multi-level house, test the range before you rely on it. Our comparison of Audio vs Video Baby Monitors explains how the two modes differ in practice.
Connection is the area where you should do the most homework. Some monitors in this category link directly between the camera and parent unit, while others depend on Wi-Fi and a phone app. A direct link tends to offer simpler operation and fewer points of failure, while app-based systems can add remote viewing and notifications. Each approach has trade-offs for range, latency, and privacy. Read Wi-Fi vs Non-Wi-Fi Baby Monitors: Range, Privacy and Security before you decide which fits your home.
Range and Interference
Range depends on the building, the number of walls and floors, and whatever else shares the same radio frequencies. Microwaves, cordless phones, and crowded home networks can all affect signal quality. Owners who live in apartments or dense neighborhoods sometimes report occasional static or dropouts. Test the monitor at the spot where you plan to sit or sleep, not just where it is convenient to set it up.
Night Vision and Low Light
Infrared night vision is standard in this category, and it works best when the camera has a clear view of the crib without glare from a window or nightlight. Owners often recommend turning off the room light entirely and checking the image before the first night. Expect some graininess, and do not count on fine detail such as a pacifier in a dark corner.
Ease of Use
Setup is usually quick if you follow the included instructions in order. The typical steps are to charge the parent unit fully, power the camera, pair the two units, position the camera, and adjust the volume. If your model uses an app, you will also create an account, grant camera and notification permissions, and connect the camera to your home Wi-Fi network.
Here is a practical setup sequence that most parents follow:
- Read the safety section of the manual before you mount anything.
- Charge the parent unit to full before the first use.
- Power on the camera at the planned location and confirm the image appears on the parent screen.
- Adjust the camera angle so the crib, the sleep surface, and the room entrance are visible.
- Test the audio at a normal sleeping volume and at a louder volume.
- If you use an app, create your account, enable notifications, and set a strong password.
- Run a full overnight test before you rely on the monitor for sleep.
Owners generally find the parent unit easier to use than the app. The physical buttons are a plus when you are half-awake and need to adjust volume quickly. The app, where available, is typically described as functional but less polished than the hardware. If app access is important to you, confirm which features are included on your version of the device.
Maintenance
Maintenance is light. Wipe the camera lens and housing with a dry microfiber cloth. Keep the parent unit charged, and replace the power adapter if it becomes damaged. Check the mounting hardware every few weeks, since vibration and temperature changes can loosen it over time.
Firmware updates matter for connected monitors. Install updates when prompted, and keep the app current if you use one. For app-based systems, change the default password and turn on two-factor authentication if the service offers it. Our guide on How to Secure a Wi-Fi Baby Monitor walks through the steps in more detail.
Battery care is worth a note. Parent units with rechargeable batteries lose capacity over time, so if you notice much shorter run times after a year or two, plan for a replacement. Keep the charging cable in good condition and avoid leaving the unit in a hot car or direct sun.
Value
Value depends on what you need. If your priority is a basic, dependable video monitor with a simple setup, the eufy Baby Monitor E21 can offer a reasonable balance of features and cost compared with premium camera systems that add sleep tracking, subscription services, or high-end imaging. If you want advanced analytics, cloud recording, or a large multi-room system, you will likely spend more and may find this model limited.
Check the warranty length and return policy before you buy. A monitor is a device you will use every night for months, so a warranty that covers the camera and parent unit gives you peace of mind. Also look for any subscription requirements. Some connected devices work fully without one, while others place certain features behind a paid plan. Confirm this on the product page.
Buying used is an option for some baby gear, but monitors deserve extra caution. Firmware, batteries, and security settings may be out of date or unknown. Read our notes on Buying Secondhand Baby Gear: What Is Fine and What to Avoid before you consider a used unit.

FAQ
Is the eufy Baby Monitor E21 safe to use in a nursery?
Monitors are generally considered safe when placed and maintained correctly. Keep the camera and all cords out of the crib and out of reach of the baby, and follow the manufacturer’s distance and mounting instructions. If you have specific concerns about your baby’s health or sleep environment, consult your pediatrician.
Does the eufy Baby Monitor E21 need Wi-Fi?
That depends on the configuration and the feature set you choose. Check the current product listing for the connection type. If you want to avoid network dependence and reduce exposure to home network security issues, a non-Wi-Fi option may suit you better.
How do I improve picture quality in low light?
Turn off nearby lights, remove reflective surfaces from the camera’s view, and make sure the camera is not pointed at a window. Mount the camera at a height and angle that shows the crib clearly without glare. Test the image at night before you rely on it.
Is this monitor worth buying for a second-floor nursery?
It can work, but range is the main variable. Test the monitor from the room where you will use the parent unit, and consider the number of floors and walls between the camera and the parent. If your home is large or has thick construction, compare range specifications carefully before you buy.
