Backup sensors and cameras are brilliantly practical, but if you’re not ready to upgrade your older, less tricked out car just yet there’s FenSens. Installation is as easy as mounting a license plate cover except for the use of security screws with the included screwdriver. Then, pair it to your smartphone using Bluetooth and fire up the accompanying app. FenSens’ integrated sensors will warn you via your smartphone beeping if your car is getting close to an object while simultaneously displaying distance from nearby obstacles on its screen. And battery is hardly an issue: one charge lasts for about five months at which point it’s recharged by plugging into USB like any modern device.

Available soon for preorder. Hit up FenSens for deets – $100
