Is the data encrypted? Which data protocols are used to ensure the traffic will not be hacked?

ANMEATE Baby Video Monitor features 2.4GHz FHSS (Frequency-Hopping Spread Spectrum) secure wireless transmission technology. The monitor provides safe and secure Point to Point digital encryption wireless transmission. The unit operates in 2400-2480 MHz auto tuned frequency, reducing the risk of interference with any other electronic device working in its vicinity.

For best results it is suggested that there should be distance of at least 3 feet between camera unit, parent unit and any other electronic device in your house for smooth reception of audio and video signals.
