What is a DECT Digital Baby Monitor

Question: What is a DECT Digital Baby Monitor?

Answer: DECT digital baby monitors are slowly making their way into more homes, and at lower prices. Should you buy a DECT baby monitor, or will a regular digital baby monitor do?

DECT stands for Digital Enhanced Cordless Communications. It's basically a special frequency, 1.9 GHz, that is reserved for voice technologies. Other digital baby monitors might operate on the 2.4 GHz frequency. They're encrypted, so you have a layer of security versus an analog baby monitor, and the neighbors won't hear your baby crying when they pick up their cordless phone. However, there could be other devices in your home that use that same frequency that could interfere with the digital baby monitor. One common culprit? Wireless routers.

The uncommon frequency of the DECT digital baby monitor is its biggest advantage. It's really unlikely that you have other things in your home that operate on the DECT frequency. In a test by Consumer Reports, a DECT phone and a DECT baby monitor did not seem to cause interference with one another, though, so even if you have other DECT devices, you might not encounter a problem.

Should You Buy a DECT Digital Baby Monitor?

If you know that you want a digital baby monitor to take advantage of the security features, and you want to reduce the chances of any interference from other electronic devices in your home, a DECT digital baby monitor could be a good choice for you. Currently, there are only a few DECT baby monitors on the market, and the majority still cost more than $100.

Digital and Analog Baby Monitors, What's the Difference?

Question:
What's the Difference Between Digital and Analog Baby Monitors?

Of the two styles of audio baby monitors, analog and digital, each has their own advantages and disadvantages. Should you buy an analog baby monitor or a digital baby monitor? Surprisingly, some trial and error may be required to find the right answer!

Answer:
Analog Baby Monitors
Analog baby monitors are usually inexpensive, and they're widely available, so you're likely to be able to find one that meets whatever unique baby monitor need your family has. Analog baby monitors generally use the 49 mHZ or 900 mHz frequency, and it's a little like a radio channel in that you might get a lot of static and interference from other things nearby that are trying to use the same channel. There are plenty of electronic gadgets that share these frequencies, so analog baby monitors often come equipped with several channel options that you can change manually to find one that's clear, or the monitor may have an automatic channel scanner that tries to minimize electronic interference. Some analog baby monitors use the 2.4 GHz frequency, 2.4GHz baby monitor may offer a little less interference.
A second problem with analog baby monitors comes if you live in close proximity to other people. When your baby monitor is competing for frequency space with cordless phones or other baby monitors, those signals are going to cross paths. The result could be that someone else hears your baby crying in the middle of the night, or you get to hear the neighbors' awkward fights.

Analog baby monitors, in general, have a weaker signal and can't be used for long distances like some digital baby monitors can. Most can handle walking around the average home, though, so unless your home is very large, this may not be a problem.

Digital Baby Monitors
Digital baby monitors tend to cost more than analog baby monitors, sometimes by quite a lot. Digital baby monitors still operate on a frequency, often 2.4 GHz, (though you won't often see frequency listed on the package, strangely enough), but the signal is encrypted so that others can't hear what's happening in your household when those signals cross paths. Although the connection is secure in that no one can eavesdrop intentionally or accidentally, that doesn't mean you won't have any trouble with interference. Many parents report that their digital baby monitors wreak havoc with wireless routers. Others have trouble with cordless phones causing noises on their digital monitors.
The only way to have a secure connection plus a nearly interference-free guarantee is to purchase a DECT digital baby monitor. These baby monitors use a newer, less common 1.9 GHz frequency that doesn't seem to be prone to interference.

The final consideration with digital baby monitors is whether or not the pulsed signals are harmful. I have not seen any conclusive evidence on this topic, but most parents I know who've mentioned it feel that it's a "better safe than sorry" issue. The type of signal coming from the digital baby monitor is stronger, and different, than that of the analog baby monitor. To be clear, I do not think this is a reason to stay away from digital baby monitors. If for some reason you need to position the baby monitor right by your baby's head, consider an analog monitor. If you choose a digital baby monitor, allow at least a few feet between baby and the monitor, to be on the safe side.

Digital, Analog, or DECT?
Unless you live in a household that is totally free of other electronic devices, it's possible that you'll get some sort of interference with both digital and analog baby monitors. You may need to try several types to find the one that works best for you. If you're not up for the trial and error, the one sure thing in baby monitors is DECT digital technology, but be prepared to pay for it. Only a few DECT digital baby monitors are available now, and most start around $100.
