Baby video monitors

Baby video monitors are the most widely used type of baby monitors because you do not just hear but also view your baby while you are not right there with them. they come in two different types where by some are digital while others analog so after knowing how each for these work you then choose which one best suits your needs.



How they work:

Any video monitor always comes with a receiver and transmitter where the receiver is the one that you carry or keep in your room and the transmitter is the one put in your baby’s room. In the case of video baby monitors it will be a camera. The transmitter therefore sends data in form of airwaves through a certain frequency and video images to the receiver. The receiver is in most cases designed with an LCD screen where you read, see and listen to all information from the transmitter. Depending on the nature through which the transmitter receives signals it is very easy to determine if it a digital or analog baby monitor. Of late some of them even have infrared lights or a night light which helps you to view your baby even when the lights are off. Some are even more advanced that they even have in-built lullabies.

Analog baby monitors:

For decades this has been the technology used in most baby monitors, an analog baby monitor will capture uninterrupted audios and videos but when it comes to transfer, it transfers the information in bits. Since you receive the signal as a whole you will not know that is it is first broken up but that is how analog baby monitors work.  Therefore before signal is transferred from the transmitter to the receiver it is first broken down but by the time it gets to the person using the receiver it has already been turned into a full audio or video. Just the way a radio does it, it is the same way the analog baby monitor works. The main drawback about analog monitors is the fact that their signal can easily be interrupted by cordless phones or any other baby monitors that are close by which makes them extremely insecure.

Digital baby:

This is found in the newer versions since it is the most current technology, a digital baby monitor has much better video and audio data encryption as compared to the ancient analog baby monitors. Here signal is broken down into various codes when being transferred over a radio frequency. By the time it gets to the receiver is will be already restored in the correct format and order which is it can play and be transferred nonstop. The signal of digital baby monitors is very clear reason being it eliminates any feedback, static and gets rid of any interference.

Movement monitors:

Baby movement monitor work with motion and works with the help of sensor pads, all you have to is place the monitor below the baby’s mattress so that it senses movement from the baby. They come with an alarm sound that notifies you once the baby stops making any movements after 20 seconds.

Baby audio monitors:

These in most cases perform just like the video monitors only that audio monitors only work with sound. Once you make any sound of discomfort or cries, the baby audio monitor is always there to notify you so that you can attend to the baby as fast as possible. Some of them come with a talk back feature which allows you to talk to your baby as a way of soothing before you actually get to them, some even have LEDs to show how much volume is in the baby’s room and night lights that will help you see things that are a distance away from you.

Additional baby monitor features:

VOX(voice activation): this turns on the monitor when it has switched into standby mode so that even when you are asleep you will still get the notification. This feature also greatly helps in preserving the battery of your baby monitor.

Set of lullabies: some baby monitors come with a set of lullabies which help to calm your baby down once she starts crying and also help to make the baby go back to sleep.

Zoom/pan/tilt cameras: it is now much easier to get images or objects much closer to you when they are actually far away.

Multi-camera transmission: of late baby monitors are designed to expandable to more than just one camera, you link your monitor to over four cameras and view what is happening in more over four places.

Intercom or two way communication: with this it is very easy for you to keep in touch with your family members, you do not just hear what it in your baby’s room but also get to speak back.

Safety tips:

  • If your baby has complications when it comes to breathing or has asthma then a baby monitor will be of great advantage as it helps you to track their breathing pattern and also give you the parent peace of mind.
  • Keep the monitor a distance away from your baby because it might wake your baby up as they react to every single sound.
  • If your baby monitor is corded, take extra caution to always keep the cord very far away from baby’s reach. They could get shocked by accidental electric shock and get strangled by the cord.
