Dash cams differ in resolution and in how many cameras they can combine into one system. The 70mai, IMOU, Dahua and Transcend line-up covers both plain 1080p front cameras and 4K models that accept a separate rear or cabin module. It is worth comparing the field of view, the Wi-Fi link to the phone app and whether a memory card is included — with some models it has to be bought separately.
