Please carefully review the model comparison pictures. Sierra Model E is only suitable for vehicle styles with an auto-dimming function and no sensor cover. The corresponding ASINs for Model E are B0D2NW57KG and B0D2P1QN6X. 4K Image and Ultra HD 2160P Video: Upgraded with an f/1.8 large aperture lens and a CMOS IMX335 chip to enable high-definition video at 2160P/30fps, this OEM-style dash cam provides 4K image performance in all aspects. It displays decent dynamic range and precise colors and can record clear video under low or high light conditions. Built-in WiFi and Free App: The built-in WiFi provides higher definition and faster download speed. The free, user-friendly app makes it convenient to view real-time videos on your phone and download or transfer important footage to your PC. You can also share videos on social media whenever you want. Please note: Your car must have an auto-dimming rearview mirror plug power adapter (10-pin square plug). Otherwise, power can only be obtained through the OBD port or fuse box. For parking monitor functionality, an OBD power adapter or fuse box power adapter (ASIN: B0CXXXV4YG) is required. IMX 335 STARVIS Sensor: This dash cam is powered by the advanced STARVIS IMX335 image sensor, delivering a wider dynamic range, enhanced light sensitivity, and clearer footage with reduced noise and motion blur, even in low-light driving conditions. It does not support adding a rear camera separately if you already have the single front camera, as the PCB boards are different
