Baby monitors are safe when set up correctly, but they come with real risks that most parents never think about. The biggest concerns fall into three categories: cybersecurity vulnerabilities in Wi-Fi connected models, physical hazards like cord strangulation, and misleading health claims from monitors that track your baby’s vital signs. Each of these is manageable once you know what to look for.
Wi-Fi Monitors and Hacking Risk
Wi-Fi baby monitors work by sending video from the camera to your home router, up to a cloud server, and back down to an app on your phone. Every step in that chain is a potential entry point. Stories of strangers talking to children through hacked baby monitors aren’t urban legends. The VTech data breach exposed millions of accounts because of weak encryption and poor password storage. Most incidents, though, trace back to something simpler: reused passwords or software that hasn’t been updated.
The most common vulnerabilities include default or weak passwords, outdated firmware with known bugs, and a router feature called UPnP that automatically opens network ports for easy device setup but can also let outsiders in. Some monitors have shipped with hardcoded streaming credentials that anyone with basic technical knowledge could exploit. Researchers found that the Victure IPC360, for example, had factory-set login details for its video stream and enabled remote access protocols by default, making it vulnerable to hijacking if the owner never installed updates.
Cloud account takeovers are another concern. If the password you use for your monitor’s app is the same one you used on a website that’s been breached, attackers can log into your camera feed without touching your home network at all.
How to Secure a Wi-Fi Monitor
The single most important step is changing the default password on both the monitor and your router to something unique and strong. Beyond that:
- Enable two-factor authentication on the monitor’s app account so a stolen password alone isn’t enough to get in.
- Keep firmware updated. Outdated software is the most common entry point for hackers. Check for updates regularly or enable automatic updates if your device supports them.
- Set your Wi-Fi to WPA2 or WPA3 encryption and disable WPS, which is a convenience feature that weakens your network security.
- Turn off UPnP and remote administration on your router. UPnP can open ports without your knowledge, and remote admin lets outsiders manage your router settings.
- Never reuse passwords from other accounts, especially ones that may have been involved in data breaches.
Access your monitor through its official app rather than exposing the camera directly to the internet. Manufacturer apps use encrypted connections that are significantly harder to intercept than a raw video stream.
DECT Monitors: A More Private Option
If hacking is your primary concern, DECT (Digital Enhanced Cordless Telecommunications) monitors eliminate the issue almost entirely. These audio-only or basic video monitors operate on a dedicated frequency band, not your home Wi-Fi network. They use automatic channel selection and built-in data encryption, which means the signal can’t be intercepted by someone on your network or through a cloud service. Philips markets its DECT monitors as offering “zero interference and 100% privacy,” and that’s a fair description of the technology. The tradeoff is that you lose features like remote viewing from your phone, sleep analytics, and cloud-stored video.
What Baby Monitor Apps Collect
Smart monitor apps collect more data than most parents realize. A 2023 study published in the Journal of Cybersecurity and Privacy found that baby monitor apps routinely collect IP addresses, device IDs, cookies, tracking elements, and device information. Third-party data sharing goes further, extending to user online activities. This data isn’t just used to run the monitor. It feeds advertising networks and analytics platforms. As Jen King, the director of consumer privacy at Stanford Law School’s Center for Internet and Society, has noted, hackers sometimes use devices like baby monitors as training grounds to test their skills, and every piece of collected data increases the potential fallout of a breach.
If privacy matters to you, read the app’s privacy policy before buying the monitor, not after. Look specifically at what data is shared with third parties and whether you can opt out.
Cord and Mounting Safety
The most immediate physical danger from a baby monitor isn’t digital. It’s the power cord. The American Academy of Pediatrics warns parents to keep the infant sleep area free of dangling cords, electric wires, and window covering cords because they present a strangulation risk. This applies directly to baby monitor cables.
Place the monitor at least 3 feet from any part of the crib, bassinet, or play yard. Wall-mounted cameras should sit 5 to 6 feet off the floor, angled downward at about 30 to 45 degrees for a clear view of the baby’s face and chest. Run the cord upward from the monitor first, then across the wall, then down to the outlet, so no slack ever hangs within reach. Plastic cord channels (sometimes called raceways) or cord clips every 12 to 18 inches keep cables flat against the wall. Never drape a cord over the crib rail.
If you’re placing the monitor on furniture instead of mounting it, make sure the piece is stable and anchored to the wall with anti-tip brackets. Babies eventually become climbers, and an unsecured dresser or bookshelf can topple. For renters who can’t drill into walls, freestanding camera stands with heavy bases or heavy-duty adhesive strips rated for double the monitor’s weight are alternatives.
Vital Sign Monitors Don’t Prevent SIDS
Many baby monitors now claim to track heart rate, blood oxygen levels, or breathing patterns. Some parents buy these specifically hoping to reduce the risk of Sudden Infant Death Syndrome. The FDA has issued a direct safety communication about this: no devices, including infant monitors, have been authorized to prevent SIDS or Sudden Unexpected Infant Death. The agency states it is “not aware of any clinical or scientific evidence” that currently available baby products prevent or reduce the chance of SIDS.
Most of these consumer-grade vital sign monitors are sold over the counter without FDA marketing authorization, meaning the agency has never evaluated whether they actually measure what they claim to measure with any reliability. The FDA explicitly warns parents not to use products marketed with claims to prevent or reduce SIDS. The AAP echoes this position, stating that it does not recommend video or direct-to-consumer pulse oximetry monitors as a strategy to reduce the risk of sleep-related deaths.
False alarms are a practical problem too. While most research on false alarm rates comes from hospital-grade equipment in neonatal units, where one study found alarms triggering roughly every 9 minutes with a high proportion being false, consumer devices face similar accuracy challenges with less sophisticated sensors. Frequent false alarms can spike parental anxiety without providing meaningful safety benefits. If your baby has a diagnosed medical condition that requires vital sign monitoring, a pediatrician will prescribe a medical-grade device, not a consumer product from Amazon.
Recent Recalls Worth Checking
Baby monitors occasionally get recalled for fire hazards. In February 2026, the Consumer Product Safety Commission recalled about 81,800 Babysense Max View Baby Monitors (model VBM55) because the parent display unit could overheat or spark while charging. The monitors were sold on Amazon, Walmart, and Babylist between January 2023 and December 2025 for $90 to $180. Eleven overheating incidents were reported before the recall, though no injuries occurred. If you own one, stop using the display unit and contact Hisense for a free replacement.
You can check whether your monitor has been recalled by searching the CPSC’s recall database at cpsc.gov. It’s worth doing for any secondhand monitor, since used baby gear frequently predates safety recalls.
