Baby monitors give parents peace of mind and play a vital role in keeping babies safe. As infants sleep, they sometimes become entangled in covers, which is uncomfortable and possibly even dangerous in rare cases. With baby monitors, parents can listen for the sounds their babies make as they move around their homes handling other chores. Parents can immediately check on babies if they cry or make strange noises.
Analogue or Digital Baby Monitors
Some low-cost baby monitors use an analogue signal that transmits audio through radio waves. This is not usually a huge problem, but other people can tune into the signal or signals could get crossed. Digital baby monitors are more secure and accurate.
Audio or Video Feeds
The biggest decision to make when shopping for a baby monitor is whether to get an audio baby monitor or a video baby monitor. The cost difference is substantial with video monitors being very expensive, but a camera offers even more security to parents and their children. Audio monitors only transmit sound, although this is often enough to keep tabs on a baby. A baby monitor with video also allows parents to determine the immediacy of the need. Sometimes a baby wakes up and cries before going back to sleep. The parent can watch and decide whether or not to go check on the baby right away. In fact, many experts recommend that parents not run immediately to their babies as soon as they cry because it encourages crying. The video feed can help parents assess the situation.
Baby Monitor Frequency
Basic wireless baby monitors use a 49 mHz frequency that has a limited range. In a large house or when parents want to do some work outside, they need baby monitors with more power. In those cases, 900 mHz monitors have a longer range, but they sometimes experience interference with other older wireless devices that use the same frequency. The 2.4 gHz monitors have the longest range, but because Wi-Fi systems run on that frequency, problems still sometimes occur. The best baby monitor frequency is 1.9 gHz because very few other devices use the DECT technology.
Wi-Fi Baby Monitors
Wi-Fi baby monitors allow parents to listen to and watch their babies using mobile phone apps. This means parents do not even have to be home to monitor their babies while someone else cares for them. However, the app only works when parents are not using their mobile phones for other purposes. The concept is more of a quick-peek novelty than a practical solution.
