The unit was installed by my gate technician with ease. We are happy with the Product quality and build and video and voice quality. Wish the power cable on the display screen was slightly a bit longer however managed to make a plan to place it . I will soon pair the display screen with a second display screen unit so I have two points inside the house to view and answer the bell from. Before I miss this Important one . I’m very happy with the ordering process and speed and efficiency of the company I ordered from.
