A word of caution about extremely cheap baby video monitors (we're talking devices that cost less than $50): they're not known for their security and can be hacked. Be sure to always change the default password of any connected device you purchase. You can also protect yourself by sticking to known vendors who post frequent firmware updates and have easy-to-reach customer support.
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.
Our testers preferred the Baby Delight’s parent unit — its buttons were more responsive than Angelcare and it was easier to set up. This movement monitor uses a cordless magnetic sensor instead of a pad. Because the sensor is clipped onto your baby’s onesie, right next to their chest, the alarm won’t go off if you forget to disarm it before a middle-of-the-night feeding.
If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
