Technology has come a long way in just a few short years. I remember our first computer. It was over $2,000 and did not have the power of a basic and cheap tablet available today. The first baby monitors did not have good range and were susceptible to all kinds of interference. Now there are ones that transmit clear high resolution video along with audio. Some offer data encryption for securing the video, and you can even get models that pan, tilt and zoom. These are great to look for that subtle rise and fall of the torso for parents who only are happy when they see there baby breathing while sleeping. Hey, I do the same thing!
Fancy baby monitors are even good for keeping an eye on pets. Some monitors even come with sensor pads to monitor breathing and movement. The top quality ones could help parents worried about SIDS be able to get sleep. I have no problem in utilizing technology to keep people safer. If I had it my way, I would make safety technology freely available to everyone every where. We bought the best monitor for our baby that we could afford. It does have the sensor pads to monitor breathing. In thinking about monitors for babies, I was considering what, in our culture, had them become a necessity in the first place.
We have rooms in our homes for the individuals that live there. Most children get their own room as soon as they come home from being delivered. This separation of the baby from the mother does require them to then be checked on very frequently, and baby monitors are the easiest way to make that happen. Babies can get used to sleeping through the normal noises of daily life. We just think we need to sequester them into a quiet room behind a closed door. Some cultures have the children and adults all in the same room. So, our different way of living has driven the development of the baby monitor technology.
