Choosing a baby monitor camera means weighing screen size, WiFi reliance, and expandability. This guide breaks down the key features and trade-offs to help you pick the right video monitor for your nursery.
Quick answer
Focus on whether you prefer a dedicated screen or app-only monitoring, check for low-EMF design and WiFi failover, and confirm the system supports multiple cameras if you plan to monitor more than one child.
Screen vs. app-only: a key trade-off
A baby monitor with its own screen gives you a dedicated, always-on display that works even if your phone is in use or your WiFi is down. The trade-off is that you carry an extra device. An app-only monitor lets you watch from your phone or tablet, but it depends on a stable WiFi connection and the app running in the background.
If you prefer not to rely on your phone for nighttime checks, a monitor with a dedicated screen is the more reliable choice. If you want to keep your pocket free and already use your phone for everything, an app-only system saves desk space and money.
Low-EMF and WiFi failover matter more than you think
Some baby monitors advertise low-EMF (electromagnetic field) emissions, which can be a consideration if you plan to place the camera close to the crib. The Harbor Baby Monitor is described as a one-of-a-kind low-EMF system, meaning it is designed to reduce exposure compared to typical WiFi cameras.
Another overlooked feature is WiFi failover. If your internet goes out, a monitor that can maintain a local connection between the camera and the screen keeps you watching. The Harbor monitor is noted for ensuring constant connectivity even when the internet is out, which adds peace of mind.
Expandability for multiple children
If you have more than one child or plan to, check whether the system supports additional cameras. The Harbor system allows you to control up to four cameras on the monitor screen or an unlimited number on the app. Each feed can be individually controlled, including turning audio down for older kids and setting motion alerts.
An additional camera (like the Harbor Additional Camera) lets you monitor multiple rooms without buying a whole new system. This is more cost-effective and keeps all feeds on one screen or app.

How to decide: 4 decision rules
- Do you want a dedicated screen?: If yes, choose a monitor with its own display (e.g., Harbor Baby Monitor with 10" screen). If you prefer using your phone, pick an app-only model (e.g., Harbor Baby Monitor Mobile Only). A dedicated screen works without WiFi; an app-only model is more portable.
- How many cameras do you need?: For one child, a single-camera system is sufficient. For two or more, look for a system that supports additional cameras (up to 4 on the screen, unlimited on the app). Buying an additional camera later is cheaper than replacing the whole system.
- Is low-EMF important to you?: If you are concerned about EMF exposure near the crib, choose a monitor specifically marketed as low-EMF, like the Harbor system. Standard WiFi cameras emit more EMF; low-EMF models reduce exposure.
- Do you need WiFi failover?: If your internet is unreliable, pick a monitor that maintains a local connection between camera and screen when the internet is out. Without failover, a WiFi outage means you lose the video feed.
