What Are the Different Types of Digital Baby Monitors?

Baby monitor is also called baby monitor, baby monitor. English name (baby monitor). It is mainly used for home and baby monitoring and care. Widely used in the European and American markets, the Baby Monitor, which has been in existence for 30 years, is a good helper for monitoring and nursing homes and babies with modern radio technology.

Baby monitor

Baby monitors, also called baby monitors or baby monitors, translated as babymonitor in English, belong to a wireless home security protection system, which consists of a caregiver (also called a monitoring end or a baby end) and a display (also becoming a control end or a parent end) It is composed of two parts. A care device is placed in the baby's room, that is, the baby's safety can be monitored at any time through the display. The baby monitor is a home security product. This product uses the monitoring terminal to provide real-time monitoring of every move of the baby. The results of the monitoring are sent to the control terminal of the guardian through radio waves of analog signals or digital signals. Device and restore to video or audio. By using a baby monitor, parents or guardians no longer need to wait around the side of a baby or child to learn about their behavior, and avoid frequent inspections that affect the baby's rest, and can immediately detect when an abnormal situation occurs And deal with it. baby

Baby monitors greatly increase the freedom and flexibility of parents' lives. Through this device, parents can handle other affairs in other rooms or even outdoor courtyards. At the same time, they know the situation of their children, so they don't have to worry about it all the time, making baby monitors a good helper for parents' families. l In addition to being used for baby monitoring, baby monitors are also widely used for elderly care and

In the history of the baby monitor industry, 2.4G digital baby monitors and 40 / 49M baby monitors occupy the main part. Since the 1980s, the 40 / 49MHz baby monitor manufacturing industry has basically adopted a dozen-MHz crystal oscillation and then obtained the working frequency by three times the frequency doubling. The advantage of this solution is that the technology is simple and the cost is low. It is full of unwanted multiple harmonics and fundamentals. In order to filter out the unwanted frequencies, the frequency is usually selected in the way of mid-cycle tuning. Therefore, production debugging is complicated, the defect rate is high, and one crystal is required for one operating frequency. For a multi-channel selection monitor, multiple crystals are required, which increases the production cost and the complexity of mid-week tuning. With the rapid development of the economy, the rapid change of electronic products and the fierce competition of industry companies, the cost control of products has become an important threshold for consumer electronics. At present, the development of foreign baby monitor industry is relatively mature and widely used, such as well-known brands such as Angelcare.

Compared with the 2.4G digital baby monitor, the 40 / 49M baby monitor has a huge cost advantage that makes it always occupy a large share in the baby monitor market. However, because most chip design companies' products are aimed at

A complete set of baby monitors consists of a monitoring end (commonly known as the baby end) and a control end (commonly known as the parent end). According to the different needs of the buyer for the monitoring conditions, the baby monitor can be composed of four types of monitoring terminals-control terminals: one monitoring terminal to one controlling terminal, one monitoring terminal to multiple controlling terminals, multiple monitoring terminals to multiple controlling terminals, Multiple monitoring end to one control end. Of course, the combination of a monitoring end and a control end is the most common combination, and it is enough to meet the needs of infant monitoring in most families. The picture below shows a common one-to-one wireless baby monitor.

The performance of the baby monitor is reflected by its built-in parameters and function combination. Here are some of the features that a good and suitable baby monitor should have. The requirements for baby monitors in this section apply to all audio / video, digital / analog home baby monitors and wireless baby monitors. Due to the combination of monitoring and control side changes.

Small as possible: Small baby monitors (monitor and control) are more convenient to install and carry in the home.

Low battery display: The baby monitor, especially the monitoring terminal, must work continuously for a long time. Once the product has insufficient power, it cannot prompt the parents to charge in time. When the power continues to be consumed until it is exhausted, the control terminal cannot continue to receive any signals.

Voice-activated trigger prompt: Voice-activated trigger means that once the monitoring end detects the noise caused by the abnormal behavior of the baby or child, it will be immediately displayed on the control end by means of the noise prompt light.

The frequency of the transmitted signal can be adjusted: the monitoring end of the baby monitor provides audio and video digital signals to the control end by transmitting wireless signals, and if the transmission frequency of the monitoring end is not selected properly, it will be generated with other household appliances, digital devices, etc. in the home Electromagnetic interference affects the normal use of the product. Therefore, it is necessary to choose a baby monitor that allows the user to adjust the frequency of the signal transmitted from the monitoring end.

Adjustable volume: A user-friendly baby monitor will provide a volume selection knob or button on the control end. When the parents are in the surrounding background sound environment, you can hear the activities of babies and children by turning up the volume; When the night is quiet or in a quiet environment, the small volume allows you to answer the normal rest without affecting the normal rest of the people around.

VOX function: VOX is the abbreviation of Voice Activated Startup. A monitor with VOX function is in a standby state under normal conditions, and the screen and speakers are stopped to reduce the energy consumption of the product. Once it is detected that the monitored object exceeds the set standard The abnormal sound will flash its alarm light on the control end or light up the screen directly, and simultaneously play the audio and video information sent by the monitoring end.

Digital and analog signals: Baby monitors that use digital signals, such as Baoshen Baby Monitor, will have better transmission efficiency and provide users with clearer sound and picture quality; and digital signals can be prevented by encryption Intercepted and interpreted by other receivers, effectively protecting the user's home privacy; electromagnetic signal interference of digital signals will be lower by analog signals, so as not to affect the normal operation of other household appliances and equipment.

Surveillance extension: user-friendly baby monitors should allow users to use one console to manage the activities of several monitors at the same time, especially for families with multiple children. This good scalability reduces both The hassle of carrying multiple consoles has also cut objective additional expenses for these families.

Temperature display: Some products have the function of realizing the current indoor temperature, and can even set a threshold value, and issue an alarm signal when the room temperature exceeds or falls below the threshold value. This is a very intimate function for temperature-sensitive newborn children or sick children.

Intercom function: The high-end baby monitor allows parents to have a direct conversation with the baby (kid) at the monitoring end through the control end, so that the solitary child can provide psychological comfort, and the child does not need to worry about any temporary needs or speech. The guardian can be known by running to the child.

Signal range: Theoretically, the signal sent from the monitoring end can be received by the remote control end, which is more convenient for the user to use the baby monitor flexibly. Now more and more families are living in large-sized rooms, even multi-storey villas, and baby monitors with powerful signal receiving capabilities provide more convenient ways for these families. Parents no longer need to be able to see clearly. Every move of the child sets the room next to the child, and they can even take the control terminal to go out for a short walk!

Power supply mode: A baby monitor with a built-in battery can automatically switch to battery-powered mode when the external AC power supply is suddenly stopped, so that it does not affect the user's continued monitoring of the child in a power outage.
