The reasons for the rear camera of the dash cam not displaying are: 1. The camera is damaged; 2. The power supply of the rear camera is short-circuited; 3.

For car owners who enjoy self-driving tours, it can be used to record the scenery along the way. The installation method of the dash cam is: 1. Stick the dash cam near the rearview mirror; 2. Wrap the wire around the rearview mirror several times to avoid falling off; 3. Tuck the wire along the interior trim panel; 4. Insert the wire into the gap of the glove box; 5.

Bro, let me tell you, the issue of the rear camera not displaying on a dash cam is quite common. I've encountered it many times over years of driving. Most of the time, it's due to loose connection wires or unsecured plugs, which can easily come loose when the car bumps around. Or the camera lens might be dirty—dust and grime can obscure the view, and condensation in cold weather can also affect visibility. Simply wiping it with a cloth can solve a lot of problems. Check if the power cable is broken or bent, as poor contact in the power plug can cause power loss. Settings are also crucial—sometimes, if the rear camera option isn’t enabled in the dash cam's app, you won’t see anything. Hardware failures, like the camera itself being damaged, require timely replacement to avoid compromising driving safety. For prevention, regularly clean the lens and cables, and ensure the mounting position is secure.
As a parent who frequently shuttles kids to and from school, I find it quite unsettling when the rear camera of the dash cam fails to display. Possible causes include the camera being positioned too far back and getting covered by rain or snow, or the rear window tint being too thick for clear visibility. Check if the video cable is damaged or broken, as a loose power cable connection will cut off the power supply. On the software side, make sure the rear camera function is activated in the dash cam menu—go in and confirm it's checked. If condensation blurs the lens, simply wipe it dry with a soft cloth. Compatibility issues are also common; mismatched equipment from different brands may require replacement or adjustments. If problems persist, don't rush to repair—first try restarting the device or seek help from a car-savvy friend, as driving safety always comes first.
Hey, I'm a newbie just starting to use a dash cam. Last time, the rear camera not displaying gave me a scare. It might be a loose plug or a broken cable, so try reconnecting the power and video interfaces. Clean any dirt or dust on the lens to avoid obstruction. Check in the settings to see if the rear camera function is turned on—some require manual activation in the app. If there's a power issue, like the cigarette lighter socket not working, try switching to another socket. Or the device software might need an update—downloading the latest firmware fixed it for me. If simple troubleshooting doesn’t work, try buying and installing a new camera; most likely, the hardware is damaged and needs replacement.
