Is it necessary to reserve a cat's eye hole when installing an electronic cat's eye?

Electronic cat eyes also need to be reserved or opened before installation, because electronic cat eyes need to be connected to the host computer through cables. The electronic cat's eye is connected with the LCD screen of the big screen through the wide-angle high-pixel camera and the cable, which can display the situation outside the door in real time, and can be seen clearly from a distance, and at the same time, it can avoid the situation that the door cannot be seen clearly when there is no corridor light at night.

Ordinary cat's eyes can see the indoor situation outside the door through the cat's eye peeper, which has hidden dangers for the safety of family members. After the electronic cat's eye senses the human body in a certain range, it will automatically take photos and videos, which is a very practical safety monitoring function.
