When was baby monitor invented
In fact, it is now sold as an antique and can be found in a few museums. If you are interested and want to learn more about the Zenith Radio Nurse, you can read the original Zenith Radio Manual. The first designed baby monitor, Zenith Radio had one-way intercom and relied on an electrical circuit to transmit its analog audio signals.
During WW II, troops used hand-held analog radio devices to communicate and the biggest disadvantage was that only one conversation could occur at a time, on each channel. This is called the simplex mode. The troops managed to overcome this obstacle by tuning receivers and frequencies to different frequencies but this was difficult as they were using the lower frequency bands, 27 MHz or 49 MHz. Basically, they were limited by the limited number of available frequencies.
Below is a video describing analog baby monitors in the 49 MHz bands. The protocol was invented in by two Americans, Hedy Lamarr and George Antheil who patented their invention of a secure security protocol that successfully enabled the Allied Forces to communicate and steer torpedoes without being noticed or intercepted. The technology utilized a spread spectrum sequence which basically allowed signals to hop from one sub-frequency to another during transit.
We have a separate post with a list of top hack-proof baby monitors using FHSS technology which you can check out. It is, however, important to note that while FHSS technology was discovered in the s when the baby monitor industry was at its nascent stages, the technology was not used in baby monitors until the 90s. First, they had to discover digital signals to replace the analog baby monitors and enable encryption for better communication security.
In , a digital processing signal technology was discovered which paved the way for the digital signals technology. The patent was for an apparatus for monitoring intercom. Apart from monitoring audio, the baby monitor would allow two-way communication. This baby monitoring device would be different from the Zenith Radio Nurse in that it allowed the caregiver or the parent to communicate with the baby. It was however designed to be similar to a telephone as it had a call button and a switch and some argue that this was not entirely a baby monitor.
Frost in Australia and later in the US. The device was designed to monitor the breathing of an infant and sound an alarm in case of a cessation. The transducer was attached to a microphone and it continuously produced noise if the breathing is normal. It did send an alarm in case the breathing ceased. Patents for transmitter units, speakers, secure cords and receiver units were approved.
Companies such as Fisher-Price started manufacturing baby monitors as it had become a lucrative space compared to its traditional toys specialty products.
Fisher-Price analog baby monitors were the best selling baby monitor brands in the s. Mattel Inc. Another baby monitor manufacturing company that emerged in the s was Safety 1st which was formed in In , Safety 1st released its first baby monitor which was the best selling brand by The history of baby monitors cannot be complete without the 90s.
The s was marked by the emergence of several baby monitor manufacturers such as Safety 1st, a company that saw incredible success selling analog baby monitors.
In addition, several patents were filed which paved the way for growth in the nascent baby monitor industry. Two factors majorly contributed to the growth of the industry: News media and FCC regulations. Several TV news channels ran stories of what some cameras had revealed — mostly gross examples of caregiver misconduct when the parents were away. The shocked public began to buy the cameras, especially pinhole cameras. This fueled the development of nanny-cams, small discrete cameras which could broadcast video and audio for a range of up to about ft.
By the early 90s, Hi-8mm video formats began to catch on. FCC also made several changes to regulations of audio and video transmission in the s, mostly the range that signals could be transmitted and the frequency band. In , FCC approved baby monitor electronic manufacturers to transmit signals in the MHz frequency band and this significantly improved the audio quality as it reduced RF interference and noise.
Towards the end of the s, FCC also approved the transmission range of some reputable vendors to up to 3 miles. The most innovative patent was the wireless baby monitoring device which operated in above the MHz frequency band and was capable of operation at a relatively low DC power. This baby monitor only allowed one-way communication and was powered by batteries. This baby monitor was the first one to design a truly portable parent unit but it still had antennas to receive transmitted FM radio frequency and speakers for converting the received RF signal to audio signal.
Before Wilson Law invented this wireless baby monitor, all baby monitors produced in the s and s used the 27 MHz or the 49 MHz frequency bands. The higher frequency bands were desirable because it allowed more channels resulting in less RF interference and noise.
This baby monitor consumed very small amount of power with DC operation. It could operate on small 1. He died on the evening of April 3, , and always maintained his inn. Over 80 years since the crime and ensuing trial, many believe Hauptmann wasn't guilty of the murder of Charles Jr. In fact, some are convinced it was Charles Lindbergh who orchestrated the kidnapping as a publicity stunt, and unforeseen circumstances saw it go horribly wrong. Nonetheless, the high-profile nature of the case ensured it left behind a significant legacy.
In the wake of Charles Jr. He hoped the device would prevent further tragedies like the one that had befallen Charles Jr. In , the Radio Nurse - which closely resembles modern baby monitors - was made commercially available. Sad thing is that it often takes a major event usually with tragic outcomes for preventative devices to be created or invented. Every time I hear this story I feel for that poor child. Prior to this tragic event, ppl at the time probably felt their babies were quite safe in their own homes.
I think the only argument was that the father may have orchestrated the kidnapping himself not that the German man actually wrote the ransom notes? Leave a comment. The original ransom note.

Check out our post on What are the different types of baby monitors? The patent was for an apparatus for monitoring intercom.
It's was described as a device to monitor young children and patients. Apart from monitoring audio, the baby monitor would allow two-way communication. This baby monitoring device would be different from the Zenith Radio Nurse in that it allowed the caregiver or the parent to communicate with the baby. It was however designed to be similar to a telephone as it had a call button and a switch and some argue that this was not entirely a baby monitor.
Frost in Australia and later in the US. The device was designed to monitor the breathing of an infant and sound an alarm in case of a cessation. An electromagnetic transducer was attached to a 'cot' or baby's crib, and it was supposed to be compressed every time a child breathes. The transducer was attached to a microphone, and it continuously produced noise if the breathing is normal.
It did send an alarm in case the breathing ceased. Prior to s, most baby monitors did not use wifi to transmit signals. Analog baby monitors used the analog signal while digital baby monitors started using the 2.
It is worth mentioning here that some of the best baby monitors , the best-selling still use FHSS technology. Prior to s, baby monitors with a camera unit had gained a foothold in the 90s.
As discussed in this article above, news outlets, including TV, ran several stories of nannies that were mistreating babies when parents were away. These stories were made possible by nannycams which recorded a video of the baby when the parents were away. Parents had seen the need to purchase baby monitors.
As prices continued to fall in the s and with the emergence of wifi baby monitors , baby monitors continued to become very popular. Because of the stories, scared parents bought the nanny cams, and by the end of , video baby monitors were fairly known by a good portion of American parents. Another big development in the s was the use of wifi to transmit signals.
The internet has contributed immensely to the growth of the baby monitors. There are more than 30 patents relating to video baby monitors at present with most of them seeking to utilize the 2. All these were filed within the last two decades, and there are several other pending video baby monitor patents.
Some of these baby monitors have had immense success with consumers. Arlo baby became one of the best-selling wifi baby monitors last year with parents being satisfied mostly with the picture and video quality. Google has approved a list of cameras that are compatible with Google Home Hub, and Arlo and Nest are some of the compatible baby monitors.
