Smart Security

Smart home tech isn't just about making your home more comfortable or the lighting. There are plenty of connected devices that add an extra level of security to your house, helping you feel safer, year—round.

Among them,sensors are perhaps the easiest of these to get started with. They're simple to install and enhance the security of anywindows and doors. Elsewhere, indoor and outdoor cameras keep entrances and gardens safer, enabling you to view what's going on, day or night. Smart doorlocks and video doorbells ensure security further by keeping tabs on who's at your door, and who can gain and when.

You might already own smart devices that could double as security tech. For example, you could program a detector to tell your smart lights to switch on if movement is . Just by getting your various devices talking to one another, you can create a rathersmart security system that is controllable from your phone.

And intelligent security cameras have been a popular choice. The following are some clever home cameras, which will keep a very watch for unwanted visitors.

He Created an Eye—Saving App

Like almost every set of new parents, Bryan and Elizabeth Shaw started taking pictures of their son, Noah, practically from the moment he was born. When he was about three months old, Elizabeth noticed something strange when she took his picture. The flash on their digital camera created the typical red dot in the center of Noah's left eye, but the right eye had a white spot at the center, almost the flash was being reflected back at the camera by something. When Elizabeth mentioned the strange phenomenon to their doctor, she shined a light Noah's eye, saw the same white reflection and immediately sent the family to a specialist. A white reflection instead of a red one is a sign of cancer, and that is exactly Noah had. After months of treatment, doctors ultimately told the couple that if Noah had been sent to doctor earlier, they  (can save) his eye.

Retinoblastoma, the scientific name of Noah's disease, is treatable if (catch) early. Bryan Shaw couldn't help but wonder whether there were signs he (miss). He went back over every baby picture of Noah he could find—thousands of them— and discovered the first white spot in a photo (take) when Noah was 12 days old. As time went on, it appeared  (frequently). "By the time he was four months old, it was showing up in 25 percent of the pictures taken of him per month," Bryan, a professor at Baylor University in Texas, said.

It was too late for Noah's eye, but Bryan was determined to put his hard—won insights to good use. He worked with colleagues in Baylor s computer science department to develop a smartphone app that can scan the photos in the user's camera roll to search for white eye. Called White Eye Detector, it is now available for free. "I just kept telling that I really need to do this, "Bryan said." This disease is tough to detect.can this software save vision, but it can

save lives."

— Yes, but we    . He was on his business trip, so he didn't return home at all.

— Really? I can't imagine that he    have done such a thing.
