Frequency: Some baby monitors operate on the same 2.4GHz frequency band as household products like microwaves, cordless phones, wireless speakers, and so on. When the monitor is on the same frequency as a number of other products, you can experience interference and static. You may want to get a monitor that uses a different frequency like 1.9GHz, which the Federal Communications Commission sets aside for audio-only applications. It's called DECT, or Digitally Enhanced Cordless Telecommunications.
Security is a mixed bag, especially as baby monitors get more high tech. If tech giants like Apple and Google run into security flaws, high-tech baby monitors are sure to experience similar problems. However, some less high-tech baby monitors aren't secure, either, and many suffer from signal interference. We've checked each company's security policy to find the most secure options for you.
You might prefer one that has lights as well as sound. All the audio monitors we rated had this feature. The Philips Avent DECT SCD510, which sells for about $120, has a series of small LED lights on the parent monitor. The louder the sound in your baby's room, the more lights go on, so you'll notice his crying even with the unit set on mute. Audio monitors are generally less expensive than audio/video models.

Electromagnetic fields (EMF), or dirty electricity, is something we think needs to be discussed when talking about wireless baby monitors. Given that all wireless devices give off some level of EMF, we feel it would be negligent not to discuss the potential for possible health risks associated with the kind of radiation emitted by wireless products. While the jury is still out, and studies being done are not conclusive yet, there is enough evidence that EMF might potentially cause health problems that we feel it is better to be cautious when it comes to children's exposure than to ignore the possibilities.
Sound activation is a feature we think parents should consider. This feature creates a quiet monitor unless the baby is actively making noise and translates to parents potentially getting more sleep because they aren't kept awake by ambient noises. Having sound activation means you only hear what you want to. This feature can be found in dedicated and Wi-Fi monitors.
