The product worked fine for the first 3 months. In the third month, the camera stopped working, resulting in nothing being visible. It was installed by a professional electrician, who was called again to check it after it broke. He assured us that there was no problem with the installation and the error was purely from the Hikvision system.

Decent for its price, easy connection, no built-in power supply, no external doorbell light to illuminate the owner's name, sufficient night vision. The screen can be connected to up to 4 external doorbells
