Even with the steps outlined above, some parents may still be wary of safety concerns with wireless baby monitors.  Non-WiFi baby monitors are typically secured with 2.4 GHz FHSS (Frequency-Hopping Spread Spectrum) wireless transmission, which makes it almost impossible for anyone to hack into the camera’s feed and see or hear your baby. Non-WiFi baby monitors are also typically less expensive than WiFi monitors, they don't require the use of your phone (which can drain battery) and they don't require a WiFi signal, which is a plus for parents in areas with poor or no reception.
