Our pick

Mini 3 uses one small windshield unit and ordinary accessory power for driving footage. Reliable parked-car recording still needs constant power. 70mai M310 is another single-unit option. VIOFO A119 V3 adds a screen and GPS while keeping the rear window cable-free.
Accessory-socket power keeps installation easy, but true surveillance normally stops with the ignition.

Garmin, Mini 3
Garmin Mini 3 is a screenless 1080p front camera with a built-in polarizer and no built-in GPS or LTE. Garmin Drive configures settings. Local recording and playback need no Vault plan. Remote access needs paid Vault in a supported country, compatible app, continuing power and internet Wi-Fi. Card and parking power are separate.
Winner whenScreenless front recording with app-based setup and an optional paid Wi-Fi remote service
Screenless settings and local phone playback use compatible Garmin Drive, and playback stops recording and alerts. Ordinary local recording and playback need no Vault plan. Recording needs no constant phone connection after setup. There is no built-in GPS or LTE. Location data needs a separately purchased GPS-enabled camera in the Garmin multi-camera network. A compatible card and parking-power accessory are separate.
