The product is value for money, especially for detached houses. It makes your doorbell smart with an app on your phone, and you can see in real time who is ringing the doorbell. As soon as someone rings the bell, your phone rings at the same time. Through the app, you can communicate both ways and deal with things while you’re away from home. The only thing I would have liked is for it to record 24/7 in a loop, but it doesn’t have that capability. As soon as someone rings the bell, it records 30" before and 30" after, which means it continuously pre-records but only saves the footage if the bell is rung. For it to work properly, you’ll need an internet connection faster than 100 Mbps. If you expect to use it with a 24 Mbps connection, forget it. On the plus side, its monitor becomes a control center, and you can monitor all the cameras you have from the same company. Very useful, especially if someone covers the camera’s lens. It also has two fantastic additional features: it opens the door’s electric strike with a key fob or the mobile app, and it has a relay for opening the garage door, again via the app or key fob. The remote garage door feature has been incredibly convenient for letting couriers leave parcels when I’m away from home. Overall, for the money I paid, it was a steal considering what it can do.

It has a very good image.
It opens the electric curtain directly without an extra power supply.
On the downside: It does not have sound adjustment, neither for the microphone nor for the speaker.
The sound is very loud and not clear.
You can hardly understand what someone is saying.
The microphone picks up sounds from 15 meters away and everything becomes a mess, the person speaking with the surrounding sounds.
Mobile app... only its own.
It does not work with Tuya or Smartlife
