Unless someone invents a teleportation device much akin to the transporter in Star Trek, people will still use the front door to enter your home. And as long as the front door acts as the main barrier between your home and the outside world, using the peephole to identify who is on the other side will not change anytime soon. However, there’s no reason to resort to an old school viewport in the 21st century.
The Brinno Motion Activated Peep Hole Viewer PHVMAC uses an LCD Panel to display who is at your door, essentially replacing the convoluted viewpoint seen through traditional peepholes with a big bright digital image. Motion is detected through the peephole with the ambient light sensor, thereby triggering the camera. Once activated, the camera records the images of your visitor on an SD Card with the time and date. Not only will this product track any shady individuals trying to snoop into your home, but it will also allow you to monitor your daughter’s boyfriend trying to sneak inside while you’re away — perfect for those days when you’re not around to hang out on the front porch with a shotgun.
