Philips-SCD510-DECTDECT Digital baby monitors scramble the signal to provide a secure connection but operate across the same radio frequencies as analog monitors. Although digital baby monitors are less susceptible to static and interference than comparable analog models, there is still the potential for conflict with other wireless devices that operate across the same frequency.

Most wireless baby monitors operate on a 49 MHz, 900 MHz, or 2.4 GHz frequency, but this does not pre-determine whether or not the signal format is being transmitted as analog or digital.

Only the newer baby monitors that use 1.9 GHz frequencies, also called DECT (digitally enhanced cordless telecommunications) technology, are digital formats that are resistant to interference.

DECT technology is the latest platform available for wireless devices, including baby monitors. DECT, which is an acronym for “digitally enhanced cordless telecommunications,” refers to the new 1.9 GHz frequency that was approved by the FCC in 2007 for voice-only communications.

Baby monitors using DECT technology are digital systems that provide superior sound quality and enhanced security. Since they operate across the newer, less-crowded 1.9 GHz bandwidth, they offer zero interference from other wireless systems. The digital format encrypts the audio and video transmissions, providing a secure and private connection between the baby and parent units. Digital audio wireless systems using DECT are resistant to interference and have a range up to 300 m.
