Where is the rear camera installed for a dash cam?

The rear camera of a dash cam is typically installed at the upper left or upper right corner of the license plate. The purposes of a dash cam are: 1. To preserve crucial video evidence when accident scenes lack clear traces or are damaged, assisting traffic police in handling incidents; 2. When connected to a direct power supply, it can function as a parking surveillance system; 3. To deter drivers from reckless driving and reduce accident rates; 4. To safeguard drivers' legal rights by providing valid evidence. A dash cam consists of: 1. The main unit, including a microprocessor, data storage, real-time clock, display, lens module, control buttons, printer data, and data communication interface; 2. A vehicle speed sensor; 3. Data analysis software.
The placement of the rear camera is crucial. I find the central point above the rear windshield to be the most stable choice. This high vantage point provides a clear view of the entire lane behind, including vehicle license plates, reducing blind spot risks. During installation, avoid tilting the lens toward the ground or sky, as this can distort the footage. Driving frequently on mountain roads, I've noticed that improper positioning often leads to incomplete accident detail capture. I recommend testing the position first—activate the dashcam to check the actual footage before finalizing the setup. Route the wiring discreetly along the window seals to the front main unit to prevent distracting cable movement. Waterproofing is also essential; if your rear window has heating elements, ensure the adhesive doesn't block them. Placement differs between sedans and SUVs—SUVs' larger rear windows make top mounting more convenient, while sedans may require interior mounting to avoid protrusions. Overall, correct positioning enhances driving safety and prevents reversing collisions.
I've installed rear cameras for dash cams multiple times myself, usually mounting them at the top center of the rear windshield's interior. The position needs to be straight to ensure a wide shooting angle that covers the entire road behind. During installation, first clean the glass with alcohol, then attach it with strong adhesive or magnetic mounts; make sure the lens doesn't reflect light or get blocked by wipers. A key wiring tip is to tuck the cable into the headliner gap and pull it forward to connect to the main unit, avoiding exposed wires. Different car models affect placement choices—for sedans, mounting above the rear window works best, while SUVs or MPVs with higher rear windows can place it lower to reduce vibrations. After fixing, test the angle by previewing the image via the mobile app and adjust the lens to ensure no obstructions. I've tried incorrect positions that resulted in crooked footage and wasted power, leading to troublesome reinstallation. Remember, a stable position improves nighttime recording quality.
