we received this camera as a gift for our 2nd child. We already had another brand Philips DECT baby monitor with the same capabilities. Their operating systems are totally different. The Phillips transmits sound continuously while the Motorola cuts and fires with the emission of a sound in the child's room. Motorola offers full settings but they do not remain registered to the camera, the date such returns almost systematically to 01/01 after 2 to 3 days of operation. Autonomy suits us perfectly. Personally I prefer the Phillips because it is smaller and less cumbersome if you want to wear it on pure self go outside of the house in summer.
