Opening the door to an intruder is the last thing any homeowner wants to do. New technology lets a resident really see and evaluate the situation outside his door.Home security begins at the door. That’s where most home invasions occur simply because the door is opened to them.
While it is true a homeowner cannot keep someone out who’s intent on violating the sanctuary of the home, it is also is true that there’s no reason to open the door to trouble. The solution to this dilemma is to know who’s on the other side of a door before unlocking it.
A peephole is one way to accomplish this. To some people, a peephole dates from the “Roaring 20s” when a gangster would gain entry to a speakeasy by uttering a password through a 2-inch-by-3-inch grilled opening in a door after a covering flap was opened. This apparatus evolved into the small, round, glassed peephole that remains a popular feature today in the front doors of homes and apartments.
However, the simple device has been improved through advances in metallurgy, plastics and optics. Where a peephole once offered a blurry, distorted and narrow view of someone on the front stoop, it now can give an undistorted look at a subject as close as a few inches or as far as 7 feet from the door, even in dim light. Modern lenses give revealing panoramic views.
Still, if squinting through a small, glassed opening strikes you as inconvenient, a new generation of peephole technology is available. It features a digital unit that attaches directly to the inside of a door.
When someone knocks, a resident of a home can press a button and a full-color video image of the area outside the door pops up on a battery-powered LCD monitor screen. Screen sizes range from 2 ½ to 5 ½ inches – each of them readable with your eyes wide open. Furthermore, unlike a regular peephole that’s mounted at the eye level of the person who normally responds to the doorbell or knocking, the LCD screen can be viewed by persons tall and short.
