The cat's eye outside the gate looks bright. What happened?

Listen to your description of the problem, your traditional cat's eye should be broken on the glass, causing uneven light after coming in from the cat's eye! It is normal to suggest that you change your cat's eye! However, the traditional cat's eye has been difficult to meet the needs of family security in today's society. It is suggested that the majority of friends change to electronic cat's eyes (automatic cameras and video door warning lights), which will be a subversive improvement to family safety, Ominia!
