Very good intercom. It is a bit difficult to connect to the lock. We struggled a bit with the electrician but we managed. On the negative side, I would say that it has only one ringtone and it is not the best. Other than that, so far excellent.

For its price, the product is very good. The image is relatively good as you can see in the photo. Okay, I didn't have unrealistic expectations from the start. As for the installation, if you're not an electrician or very familiar with the subject, don't attempt to install it on your own. You will get tangled up. Only by an electrician. That's it in general terms.

Perfect for its price, I have installed 5 so far and they all work well even at a very long distance (>50m). Anyone who has an issue with the Cypriot one is because they are not an electrician

The image clarity is satisfactory even in low light conditions. The connectivity is easy for the internal device to communicate with the external one (sound - image OK). However, we were unable to open the Cypriot, so the system is practically useless as when someone rings the bell, we have to go down to open it. The connection instructions are for a different type of electric lock and not the simple Cypriot with 2 wires.

EDIT 21/11/22
With the proper instructions (from where we purchased it), it eventually worked with the classic Cypriot - just after opening it, it takes a few seconds to close again. I reconsider the poor rating as the image and sound are more than satisfactory (even in darkness).
