This is a door peephole viewer that boasts a large digital screen for easy viewing. It is well engineered to deliver reliable and stable performance. The robust housing can withstand daily wear and tear.   Different from the traditional peephole viewer, it overcomes the features of small perspective and inconvenient observation of traditional peephole viewer (opening one eye and closing one eye), etc.   It is an effective solution to the inconvenient observations of the elderly people&rsquo;s poor eyesight and child&rsquo;s not tall enough height.   It is an effective way to eliminate the phenomenon that &quot;anti-peephole viewer&quot; and other peeping equipment make &quot;anti-peeping&quot; on traditional peephole viewer in order to protect the privacy of indoor guests.   Stylish, new, simple and generous appearance highlights the safety and dignity.   It is compact and easy to install with more humanization, which can be installed easily (door&rsquo; hole is 14mm-52mm, and door&rsquo;s thickness is 35-105mm).   It uses LCD as the interior observation window with super outdoor vision of 105 degrees, showing clearer outdoor image and more realistic colors.   It is easy to operate: when the outdoor visitors touch the doorbell button lightly, the indoor guests capture outdoor images clearly through the window of LCD.   It automatically closes after 15 seconds and brings the indoor guests more convenient using experience.
