Your car doesn’t need WiFi or wireless connectivity to use RearVision.
The Car Adapter, plugged into your car’s OBD port, creates a secure wireless connection to its companion Camera Frame. Together, they connect wirelessly to the Pearl App, allowing you to see and control super-wide views of what’s behind your car – right on your phone.
Additionally, cell service is not required to use RearVision. It works the same in a city as it would in a remote area. Connectivity -- via cell or WiFi -- is only required to download the Pearl App and to receive automatic updates.
