The package includes the transmitter and receiver unit, the latter optionally be powered by batteries or can be connected to the mains. Also nice: The transmitter device acts immediately as a small, unobtrusive nightlight. Also well thought out: A small icon indicates when both devices are connected to one another. There is also a volume control, but this is not a unique feature of the Philips baby monitors facing competing products.
In addition, I like that the baby monitor - such as wireless phones and - has a so-called "Smart Eco Mode", in other words, but mainly let minimize the radiation of the appliance the range, also.
A total of my lack of striking criticisms the full five stars. The devices are easy to use, the manual (already in a box inside with pictograms illustrated) easily understandable and without unnecessary frills. Buy recommendation. Also the price / performance ratio.
