Baby Monitor Facts

Baby Monitor Facts

Digital Video Baby Monitors are a relatively new item on the market, utilizing some of the latest advances in technology. These exciting products are revolutionizing the way we monitor our loved ones and represent the next generation of baby monitoring.

By learning more about video baby monitors and how they work we hope to make you an informed consumer.

Different Types of Baby Monitors

Finding the monitor type that fits your needs The array of baby monitor choices is staggering. There are analogue and digital sound monitors, video monitors, and movement monitors, each with a variety of options.

Baby Sound Monitors

Sound monitors are available in both analogue and digital models. Analogue baby monitors are the least expensive and can still be a good value. Models are available with multiple receivers, long distance reception, and belt clips. Many have wireless capability with battery or AC operation, and may come with rechargeable batteries. Digital monitors have the same options, and give clearer sound, wider reception range, and less interference from radios and other electronics than analogue models. When choosing a portable model, an out of range indicator feature is an option to consider. Whether you chose analogue or digital, look for a model that minimizes static and has the reception range you need.

Digital 2.4 GHz

Interference Free Operation Anywhere: The latest development in video baby monitor technology is digital 2.4 GHz. Digital 2.4 GHz is completely different from older analogue 2.4 GHz systems which are susceptible to interference from other 2.4 GHz devices.

Digital 2.4 GHz systems are fully immune to interference and can work static free in an area with wi-fi networks and 2.4 GHz cordless phones. Digital 2.4 GHz systems are still limited to about the same range as older systems. So cameras do have to be within a reasonable range of the monitor like with any other system.

If you get a digital 2.4 GHz baby monitor you do not have to concern yourself about the rest of the info below about avoiding interference, which is a big advantage. We foresee digital 2.4 GHz systems becoming the norm in the future and more are on the way.

What's Different About Digital? Where analogue 2.4 GHz systems use a couple preset channels, digital 2.4 GHz cameras and monitors are specifically linked to each other. Digital 2.4 GHz allows for tens of thousands of unique possible variations on the frequency. As a result, digital 2.4 GHz monitors and cameras "lock onto" each other on their specific frequency combination. This is what allows for the static free operation.

Extra Cameras are a bit different with digital systems. Extra cameras can be added at any time, but there is a linking procedure in the user manual that you follow and there is usually a link or paring button on the camera. Be sure to review the details of the digital 2.4 GHz system you are considering to see how it handles extra cameras.

Better Privacy: On old analogue systems since they use a small number of preset channels, anyone with a compatible monitor within range can potentially pick up your camera's signal. But with digital 2.4 GHz, since the camera and monitor are specifically linked together it is almost impossible for any other monitor to view your cameras. This is just one more piece of mind for you and another benefit of going digital.

Labelling Note: Note that if a video baby monitor is labelled 2.4 GHz, but doesn't specify "digital", it almost always means it's an analogue system. So if it doesn't say digital it probably isn't.

Night Vision

Night vision solves a very important issue with video baby monitors. As we all know, babies and the rest of us usually sleep with the lights off. And the main purpose of a baby monitor is to monitor your infant while they sleep. But cameras need light to be able to see.

The solution is infrared (IR) night vision. Our human eyes are able to see what is called the visible light spectrum. The wavelengths just below the visible light spectrum are infrared (IR).

Humans are unable to see infrared light, making it fully invisible. Cameras however, can be designed to see infrared light, which is the case of the monitoring systems we carry with the night vision feature.

In a fully dark room our eyes and standard cameras require a light source to be able to see. Infrared cameras are no different; they require an infrared light source to illuminate the area, which you wish to monitor. Note that almost all night vision capable cameras are also able to operate in a normal mode with regular visible light and full colour.

Night Vision On/Off: Night vision is either automatically or manually turned on and off depending on the system. Automatic systems use a light sensor just like those found in common night-lights. This sensor automatically kicks in the night vision when light goes below a set level. On other systems there is a selector on the camera that switches the unit between normal and night vision modes. We've had customers report their night vision was "broken" when they simply failed to turn it on.

Night Vision Has No Colour: We had a return where a lady thought her system was "faulty" because the night vision picture was a greenish tint. In low and no light situations there is no colour to be viewed. Colour is the first thing to go from our eye site as light dims to dark. All digital video baby monitors when in night vision mode either switch to black and white or green monochrome. This is mainly to increase contrast to make the low light images more visible, just like professional and military night vision systems.

In the pitch dark this is where IR illuminators come in. These are small yet powerful LED (light emitting diodes) lights that are built into cameras and shine IR light. Most cameras have several IR LEDs, numbering anywhere from 6 to 18. These IR LEDs work just like an invisible flash light providing the IR light the camera needs to be able to see in the dark room. The result is the dark room is now lit so the camera can see, but since the light is fully invisible it will not disturb your sleeping baby.

Night Vision Is Very Short Range: The average range these IR LEDs are able to illuminate is up to about 2 metres. Look at the LEDs and you will see they are very small. So they will not illuminate the whole room, but will be able to provide enough IR light to the immediate area in front of the camera to allow for viewing. Again customers have reported their night vision was "not working" because they couldn't see their baby in the dark. In this situation the camera was placed across the room from the baby over 3 metres away and the small IR LEDs are unable to illuminate that far.

If we are unable to see IR light, then how do we get a viewable image on the receiver end? The answer is the camera system takes the IR image and converts it into the visible light image, which we can then view.
