    Is my camera compatible with Drive Smarter?

    Only Cobra's SC Series cameras (SC 100, SC 201, SC 200/200D, and SC 400D) are currently compatible with Drive Smarter. Drive Smarter does not support legacy Cobra dash cameras (DASH Series, CDR Series) at this time.

    Do I need to pay for Drive Smarter?

    No, Drive Smarter is a free service provided to users of our SC series cameras.

    Why am I having trouble connecting the camera in Drive Smarter?

    You may have previously established a Bluetooth connection with the camera. If this is the case, please go into your phone's OS Bluetooth menu and 'Unpair' your camera from your phone.

    How can I use the Mayday Alert feature?

    Simply enable the G-Sensor and Mayday Alert setting on your camera, and enter your Emergency Contact info into Drive Smarter. From there, Drive Smarter and the dash camera will take care of the rest. If the camera detects that you have been in a serious collision (Level 5 G-sensor event), it will automatically lock the latest recording and notify your emergency contact.

    How do I connect my camera via Wi-Fi?

    You do not need to manually establish a Wi-Fi connection to your dash cam. Drive Smarter uses Bluetooth to automatically manage connection types depending on which feature you are using within the app. If you are using a feature that requires Wi-Fi, the app will walk you through establishing a a Bluetooth connection. Note: Older Android operating systems (Android 6, 7, and 8) may prompt the user to exit the app and connect via the OS Wi-Fi menu.

    Why is Alexa not working?

    • Ensure that you have downloaded the Alexa App. You need to connect your camera to the Alexa app to enable this feature.
    • Check that the volume on your phone is turned up. The SC 400D uses its specially tuned microphones to invoke Alexa from the background of your phone and automatically reconnect when you enter your car. The phone is still the main source of audio for Alexa, enabling you to hear the replies through your car’s speakers.
    • Check that Bluetooth is enabled on your phone.
    • If you see a red bar on the camera, press the Alexa mute/unmute button on the bottom of the unit next to the power button.
