4. Learn about Frequency and How it Interference
The baby monitor works as a radio transmitting and receiving radio signals in the air at a given frequency. When used by the baby monitor is common, such as 49MHz, you may annoying static or interference devices such as mobile (cell) phone, cordless phone, microwave oven and CB radios.
The signal can be picked up in the neighborhood or passing truck driver or police car, who can be heard in private conversations. Maybe that is given to someone over the phone conversation with the baby monitor, or to hear the baby crying.
The most basic models use of 49MHz. The next step is 900 MHz, which provides a greater range, but may interfere with the older wireless phones to the same frequency. To address this, a many of baby monitors switched to 2.4 GHz. However, newer wireless phones have adopted the same frequency and Wi-Fi system also includes 2.4 GHz, so interference is a problem. The 1.9 GHz band offers the best security because it is the only one that supports the DECT technology.
Some baby monitors have multiple channels for greater transparency, avoiding possible interference depending on where you are located.
