Many new car models come with a sophisticated back camera system. Even if you drive an old car, you can always add your own camera to stay alert of obstacles in your way. The Pearl RearVision Wireless Backup Camera is an app-enabled solution that upgrades your car and lets you use your smartphone as a rearview screen.
The camera has a night vision mode. It offers audible and visual alerts to let you know when obstacles are in your way. To get started, simply attach the theft-resistant camera frame around your license plate, plug the car adapter into the OBD port, and use your phone to keep up with all the action.[where to get it]
