The worst thing on the market.
The camera constantly freezes, the temperature it shows is not correct, and it opens and closes on its own. I changed it three times and all three times it was the same

They brought it to me as a gift, so I haven't looked for similar solutions in the market. The only negative thing is that it loses sound momentarily, but only for a few seconds. Personally, I would prefer the camera unit to operate on battery and not just with a cable. However, the quality of both the sound and the camera is excellent, despite the small screen. And indeed, the screen battery lasts forever. As for the price now, there is an issue here (and the help regarding the price evolution is valuable). Because the price I find at the moment is twice as much compared to previous times, so I'm not sure if it's worth it (hence the 4 stars). If it drops again, then I would buy it again without hesitation

After 2 years of use, I highly recommend it. Although the screen is small, it has all the information with good resolution even in low lighting.

For the maisonette, it has perfect range. Very good quality for its price. Easy and simple to use. Of course, it has a very good image and the device's battery has very good durability

Very good picture. Even better at night!! Relatively small screen though. It captures sounds. Battery from old times that lasts a lot.
It does something strange and shuts down instantly making a sound (I don't know how random this is or if it has a problem, time will tell.) that it makes when the camera is not open.

Very good image and sound, good even in the dark.
Convenient that the parent unit has a battery and you can have it wherever you want, even somewhere without a power outlet nearby, like a balcony.
