Wifi Car DV is a free utility app developed by Transfluent for Android devices. It is designed to connect your smartphone to your car's DVR and enable you to view and manage video recordings directly from your phone. With Wifi Car DV, you can easily download, playback, and delete your DVR's recorded videos without the need for a computer.

One of the main features of Wifi Car DV is its firmware update service. If your smartphone is not connecting to the DVR, you need to update the firmware. The app provides a simple solution by allowing you to request a firmware update via email. However, it is important to note that the app will not work without a firmware update.

For QX3, Transfluent has released a new and more convenient app called "My carcam". The app is available on Google Play and comes with video and screenshot demonstrations. The firmware required to run the app is also available upon request via email.
