Timbre de vídeo inalámbrico con monitor de 4,3"

It was installed today and is working very well.
Clear image and the conversation is satisfactory with a quick response. The doorbell was installed at the front door and the monitor was placed next to the entrance door, at a distance of 6-7 meters with one wall in between. For someone to speak from the screen, they must press the phone button, and to hear the response, they must release the button. So you press and hold the button to listen. No problem.
The screen must have a continuous power source. . I don't know how long the battery of the doorbell lasts.
If something different arises in its future operation, it will be mentioned in this evaluation.
Satisfied for now.

It's very good if the distance at which you are going to have it is not very large. It doesn't reach from the door to the living room for me, but I have placed it in the hallway and it works well. The battery of the indoor unit lasts very little; I have to keep it plugged in all day because otherwise it stops working. However, the one outside lasts a lot longer. It's not bad for what it costs.

The transmission and reception connection is good, and the screen is not very clear, but it's worth looking at. However, there are some drawbacks such as having to press a button when speaking like a walkie-talkie, and releasing the button when listening, as well as a slow response speed when pressing the button while speaking.
