Aesthetics for the use of the device is high, but it is a plus that pleases the parents. The camera (baby unit) is really very successful design perspective. Between the baby unit and the parent unit, there are two bedrooms with three concrete walls. No bond issue, which shows that this device has a very good wifi. So far we have had no communication failure. It is prudent to 4 R03 (rechargeable batteries are not accepted) in the webcam (sorry that I use a computer term for the baby unit). For now we leave permanently plugged on current, but vowed -promis, we will put the batteries four dice tonight. We must think of a power cut that would see more than our sweetbabygirl! The night visibility automatically switches to night mode and no problem to see our little darling! The screen is equipped with everything you want, especially displays the temperature of the baby room, and you can adjust for an overheating signal in said chamber. Naturally we can communicate from the parent unit to the baby unit with lullabies, calls or whatever. But obviously it's the opposite of interest. Is that we can monitor our sweetbabygirl and hear when she wakes up. Mission accomplished with this device without any problems. The only criticism I would make is that the price of the set is a little high. But the quality is paid and you must sacrifice one or two restaurants (not McDonalds) if we want to avoid the stress of parents for the baby a little distant. I wonder how did our grandparents! We like it this device at any point of view (use and aesthetics), and we allow you recommend.
