4K resolution front and rear 1080 dash cam. The dash cam is clear. The reason for selling it is that my front windshield is not clear due to sand, and I am not benefiting from it. It has an internal memory of 128 GB. Its features include: it records by itself and deletes when the memory is full, it turns on and has its own app to transfer recordings to your phone, it has night vision, a wide 170-degree angle, and other features.
