The Ultimate Buying Guide for Dash Cam Rear View Mirrors
A dash cam rear view mirror is a fantastic tool for modern drivers. It combines a regular rearview mirror with a screen that shows you what’s happening behind your car. This guide helps you pick the best one for your needs.
Key Features to Look For
When shopping, focus on these important features. They make a big difference in how well the mirror works.
Video Quality and Resolution
- Resolution: Look for at least 1080p (Full HD) for both the front and rear cameras. Higher resolution (like 2K or 4K) gives you clearer details, which is vital if you need to read license plates.
- Frame Rate (FPS): Aim for 30 frames per second (fps). This keeps the video smooth, especially when you drive fast.
Screen Size and Display
- Screen Size: Most mirrors are between 9 and 12 inches. A larger screen shows more of the rear view, but make sure it fits nicely over your existing mirror without blocking too much vision.
- Touchscreen vs. Buttons: Touchscreens are easy to use, like a smartphone. Buttons work well even if your hands are wet or gloved.
Special Functions
- Parking Assistance/Guidelines: When you put your car in reverse, the screen should show helpful lines to guide your parking.
- G-Sensor (Gravity Sensor): This sensor automatically locks the video file if you get into an accident. This protects the important footage from being overwritten.
- Night Vision: Good night vision uses special lenses or sensors (like Sony STARVIS) to capture clear video even in very dark conditions.
Important Materials and Build Quality
The materials used affect how long your mirror lasts and how it looks.
Camera Lenses
High-quality cameras use glass lenses, not plastic. Glass resists scratches better. Plastic lenses scratch easily, and this scratches blur your video.
Mirror Casing
Look for a sturdy casing, often made from durable ABS plastic or sometimes aluminum. This material protects the electronics from heat and vibrations inside the car.
Cable Quality
The rear camera cable needs to be long enough to reach the back window easily. Check that the connectors are robust and water-resistant, especially if you install the rear camera outside the car (though most are installed inside the trunk lid).
Factors That Improve or Reduce Quality
Good features make the mirror great. Bad design makes it frustrating.
What Improves Quality?
- Wide Viewing Angle: A wider angle (150 degrees or more) lets the camera see more of the road on both sides.
- Loop Recording: This feature lets the camera continuously record. When the memory card fills up, it automatically records over the oldest, non-protected files.
- IP Rating for Rear Camera: If the rear camera is mounted outside (like on the license plate frame), it needs a high IP rating (like IP67) to keep water out.
What Reduces Quality?
- Poor Low-Light Performance: If the image looks grainy or dark at night, the camera quality is low.
- Lag Time: If there is a noticeable delay between what happens behind you and what appears on the screen, it is dangerous. Good mirrors have almost zero lag.
- Reflections: If the screen reflects too much sunlight during the day, you cannot see the image clearly.
User Experience and Use Cases
How you use the mirror affects which model you should buy.
Daily Driving
For everyday commuting, you need reliable recording and clear rearview visibility, even when the screen is off (acting as a normal mirror). Automatic switching to the rear view when reversing is essential.
Long Trips and Security
If you travel often, look for large storage capacity (support for large SD cards). If parking security is a concern, some models offer “parking surveillance,” which records if someone bumps your car while parked (though this usually requires a hardwire kit).
Installation Difficulty
Most mirrors clamp over your existing mirror easily. Installing the *rear* camera, however, requires running a cable through the headliner to the back window. If you are not comfortable with basic wiring, choose a model with a very simple rear camera setup or consider professional installation.
Frequently Asked Questions (FAQ)
Q: Do I need a separate screen for the rear camera?
A: No. The main benefit of a dash cam rear view mirror is that the screen is built directly into the mirror itself, replacing your standard mirror.
Q: Will the mirror block my view too much?
A: Larger mirrors (12 inches) show more video, but they might look bulky. Check the dimensions against your car’s windshield size. Most people find the trade-off for the extra safety worth it.
Q: How does the G-Sensor help me?
A: If you stop suddenly or get hit, the G-Sensor detects the jolt. It immediately saves the video clip leading up to and after the event. This file cannot be deleted by loop recording.
Q: Can I turn the screen off?
A: Yes, almost all models let you turn the display off. When off, the device acts just like a regular, high-quality rearview mirror.
Q: What type of memory card do I need?
A: You need a high-speed, high-endurance microSD card. Look for cards rated Class 10 or U3. Dash cams write data constantly, so standard cards wear out quickly.
Q: Is the rear camera waterproof?
A: If you install the rear camera inside the cabin (near the rear windshield), it does not need to be waterproof. If you mount it outside (like near the license plate), it must have a high IP rating.
Q: Do these drain my car battery when parked?
A: Standard models only record when the car is running. If you want 24/7 monitoring (parking mode), you usually need to buy a separate hardwire kit to safely connect the camera to the car battery.
Q: What is “WDR” or “HDR” in the settings?
A: WDR (Wide Dynamic Range) or HDR (High Dynamic Range) helps balance very bright spots (like headlights at night) and very dark spots in the same frame. This makes the whole picture clearer.
Q: How do I install the rear camera cable?
A: You usually feed the cable along the roof lining (headliner) of the car, down the pillar trim, and then into the trunk or hatch area where the rear camera is mounted.
Q: Is recording mandatory in my state?
A: Laws vary. In most places, it is legal for you to record the road ahead and behind your own vehicle. Always check your local traffic laws regarding dash cams.
