Using technology to prevent tragedy: Gary Tuchman runs a test in Texas

The grisly death of Georgia's Cooper Harris is sadly not an anomaly. Last year alone, more than 40 children died as a result of being left alone in a hot car.

But might these tragedies be preventable? Could technology be tapped into so as to guard against forgetfulness, and combat negligence?

Gary Tuchman traveled to Texas to test car seat monitors that claim to save kids from being left inside sweltering vehicles.

Watch the above video as the CNN correspondent tried out the device with the help of a parking lot, an SUV, and a reluctant six-month-old.
