We need a baby monitor for 2 different bed rooms, is there such a thing?

Q. My husband and I are expecting our second baby in 4 weeks. We also have a 2 year old. We have been looking every where for monitors to have in each of their rooms. I would need to receivers because we have a 2 story home. It seems to be impossible to find. I know Im not the only mom out there with 2 children who need monitors in their room...Please help!

A. You need two monitors and two recievers or just one reciever? If it is 2 reciever just buy two monitors with different frequencies like the summer infant hand held.


listen to other cell phone conversations with a device?
Q. how is it possible to pick up cell phone conversations with a device, or a baby monitor.

A. Only analog cell phone conversations can be intercepted with a scanner. And almost no one has analog phones anymore. The newer CDMA or GSM phones use digital encoding techniques that prevent the casual listener from intercepting the conversations.

Baby monitors will NEVER overhear cell-phone conversations. Baby monitors operate at 900MHz or 2.4GHz; cell phones do NOT operate in those frequencies. However, home cordless phones DO operate in those frequencies, and these are the conversations that are often overheard by baby monitors. Newer cordless phones use the same digital encoding used by cell phones, so a new phone won't be overheard by a baby monitor.


Why would a non-wireless router emit so much radiation?
Q. I have a TP-Link router and it's not a wireless one, yet it seems to emit quite a strong magnetic field of almost two metres, as it causes interference with my baby monitor. Should I be concerned about this? Or is it normal for a router to emit so much radiation? The thing is that the router is under my desk right where I sit to work!

A. Any piece of modern digital electronics emits electro-magnetic interference. The very high speed circuits invoved (several MHz clock frequency) conduct through copper traces on the circuit board in the thing. The copper traces act like antenna and thus emit the "noise" you hear on your baby monitor.

Even the power supply for your router could be the culprit. To achieve small size and high efficiency, the power supply "brick" will often contain high speed electronics which could also be the source of the emission.

Finally, the typical baby monitor is a pretty low quality electronic device. It lacks selectivity and is likely picking up noise from frequencies that are not important to it. A different brand monitor might not suffer this problem.

Also, better quality routers would enclose their circuit boards in a metal housing. Such enclosure would contain the EMI in a so called Faraday cage. I suppose you could put your router in a metal box and accomplish the same thing now.

Is it possible to buy a scanner?
Q. Can you buy a scanner that tunes into frequency's such as the police radios. i've herd that some can pick up cordless phones, cell phones and baby Monitors. that kind of scares me because people can listen into my conversations. i asked this question to get a general idea of just how many people have these out there.

A. Most cordless phones and cell phones can not be monitored by scanners, even if the scanner was modified to receive their frequencies. Modern cell phones and cordless phones utilize digital and/or encryption technology which can not be monitored by any scanner available to the common citizen. However, some older cordless phones can be monitored.
