... I changed 3 Motorolas and a Philips Avent, intercoms to end up with this one. It does everything it claims and works correctly. It has good range (the most important thing is that there is a floor difference, living room with bedroom, and it responds perfectly... in my house). Good build quality. It has a built-in night light, with the option for pulse and any RGB color selection you desire. Good and clear screen - control unit (it's not HD - 2K as it claims, but it has good accuracy and performance). Good quality plastic and screen (it has survived falls). Tremendous sensitivity in the microphone, even in the lowest setting it will "hear" the wall switch (when you turn on the light) in the adjacent room! Inaccuracy regarding the temperature sensor. Probably because it is located in the base, inside the camera, and the camera operates 24/7... the device naturally heats up to some extent... the temperature-humidity sensor shows incorrect readings (for those who find this important). Both the screen-control unit and the camera operate with a type-C port. Everything required is included in the package (even a base to be attached to the wall or high up on a piece of furniture. These silicone decorative ears can be removed and not used, without affecting the device's functionality. The indicator LEDs (blue in operating mode, red when out of network) around the lens can be disabled and it will function correctly without them, even in complete darkness where it has very good and clear image or which is quite wide-angle. The application works correctly on a 2.4G network. The battery of the screen-control unit is not the best but it can easily last for at least two hours with the screen on, there is an option after a certain number of seconds (user-selected) for it to turn off and activate as soon as it detects motion or sound (fortunately, these alerts can be disabled or their sensitivity adjusted), in that case, the battery definitely lasts much longer. It doesn't freeze and provides access to all camera settings even from the mobile phone. The application still works when the mobile phone is connected to a different network or a mobile network with data enabled. The application, if the account is shared, can work on more than one smartphone. Finally, of course, it is pan+tilt with a quite good range of rotation. Both the camera and the control unit-screen have slots for Micro-SD cards (high capacity, up to 128GB) to store clips both in the device and to be downloaded directly to the mobile phone from the camera. I would like a little more range for the control unit-screen, but in any case, overall it is much better and equally high quality compared to the other, more famous (and more expensive) devices of the same kind.
