Who this is for and how it works

This device is intended for drivers and passengers who want an extra layer of safety when exiting their vehicle in busy traffic or urban environments. It mounts easily to the interior door panel, typically near the handle, and uses an infrared sensor to monitor the area outside the door. When the sensor detects an approaching object while the door is being opened, it triggers a voice prompt and a colorful light alert to warn the occupant to pause and check their surroundings.

Good to know

This device is designed for general use across most vehicle models. To maintain the sensor's effectiveness, ensure the lens area remains clean and free of obstructions. The unit features a detachable base design, allowing you to easily remove the main alarm module for charging without needing to peel off the entire mount. It is compatible with standard USB charging cables. Please note that while this device provides an additional safety prompt, it does not replace the driver's or passenger's responsibility to visually check for traffic before opening a door.
