Own an older car but still interested in having a backup camera? FenSens has you covered. The company makes sensors that you can install on your license plate––which, when paired with your smartphone, help you make sure you don’t hit anyone when you back up. Its referring domains and organic traffic are both trending up. 

What’s next: Since 2018, backup cameras have been required on all new cars. But for people who still have older cars, wireless sensor technology will be in high demand.
