Let me start by saying that until I had this system installed, I had never once thought that I would ever want or need a Dashcam.  After several weeks using this ZeroEdge Dual-lens Car Camera , I am very happy that I accepted this opportunity to review this item (and had it professionally installed).  The system consists of a rather nice sized rear view mirror that is attached over your existing mirror.  In the middle of the mirror is a 5” diagonal screen that acts as the display for the forward-facing camera, as well as the rear camera (more on the rear camera later).

Now, what comes in the box?

Installation of the ZeroEdge Dual-Lens Car Camera system can be easy or hard, depending on your skill, patience, and aversion to risk.  It also depends on how important aesthetics are to you.  Personally, after owning cars for almost 35 years, I know that messing with a car’s electrical system if you are not a professional is like messing around with your computer’s registry.  Meaning, it doesn’t take much to make a small problem into a much larger problem.  Some of you may be perfectly comfortable installing this yourself (BTW, installing the mirror itself is pretty easy – the rear-view camera is trickier).  However, in my case, I had to also appease my wife by ensuring that the device didn’t make the car messy and cluttered with lots of wires.   The below photo shows the front and rear views of the camera.


So what did I do?  I took my car to my nearest Best Buy and paid their Geek Squad to install this.  I won’t lie – this was much more expensive than I thought to install.  Geek Squad charged me $219.00 total to install both the mirror and the rear-view camera.  But, as you can see from the below photos, the device looks factory installed.  If you go to’s Web site, you will see several reviews online for this device and in all of the pictures, there are cables dropping down from the mirror to the USB Car adapter.  In my installation, the wires to the mirror go up the windshield, and to the driver’s side and into the dashboard.  There is no need for the system to be plugged into the car charger port.  The rear view camera was installed over my rear license plate and has no wires showing at all.



Now…back to my wife.  When I came back from Best Buy and I told her how much I spent getting the ZeroEdge Dual-Lens Car Camera installed, I thought she was going to have a stroke. To say she was angry would be an understatement.  All of that faded away when she got behind the wheel and started backing up and the back-up camera turned on.  She loved it.  She was also very impressed with the installation and the ease of use of the device.

Setting up the ZeroEdge Dual-Lens Car Camera is easy.  The system automatically turns on when the ignition is turned on.  You press and hold the M/Mode button all the way to the left, and the settings menu is displayed.  Here you scroll down and set the date/time, video quality (780p or 1080p HD), turn on/off the microphone, select the sensitivity of the movement sensor, set the time of the looping recording (2, 3, or 5 minutes).  Scrolling up and down the menu is easily done using the up and down buttons below the mirror.  Also accessible via the up and down buttons, are the view mode available to the user while driving.  That brings me to how is driving with the ZeroEdge Dual-Lens Car Camera system?

As I said earlier, the unit turns on automatically when you turn the ignition on.  When it turns on, the view on the mirror is from the forward facing camera, with the rear camera’s view in a picture-in-picture on the upper right corner of the screen.  When you shift into reverse, the view changes to the rear view with the path behind you highlighted (see picture below).  For me, this one feature is priceless.  After seven major spine surgeries a few years ago, turning my ahead all the way around when driving in reverse When you shift into drive, the view shifts to forward facing.  You have four different view options.  Full-screen forward, full-screen rear, forward view with rear picture-in-picture, and rear with forward picture-in-picture.  The rear camera records and displays at 480p.  During daylight, I find that I have no problem seeing through the camera view and using the mirror as a mirror.  At night, however, the camera is quite bright and some could find it distracting.  It is definitely harder to use the mirror at night, but I have become quite used to it.  I drive with the full screen rear view on.  You can always turn it off if you find it too distracting.


Below you will find a short video demonstrating the use of the system with the various camera views displayed.

The ZeroEdge Dual-Lens Car Camera comes with a 16 GB micro SD card (the system supports up to a 32 GB card), recording approximately 3 hours of video (1080p front view), longer if recorded a lower resolution, which you insert into a slot at the top of the mirror.  The system records video into two different folders.  One for the front facing camera and one for the rear facing camera.  Plugging the card into a computer just requires an SD Card adapter and an SD Card reader.

Here are some direct videos from the front camera:

  1.  Night

2. Day

Here is a video from the rear camera as well:

I know that many of you might be thinking why do I need a dash camera or rear-view camera?  The truth is that you don’t – but why wouldn’t you get one?  Between all of the cases of insurance fraud and, shall we say, embellishment of the “facts” when it comes to encounters with law enforcement, wouldn’t it be nice to have a visual record of events.  There is a reason why rear-view cameras are so popular these days and why some car manufacturers are starting to include this feature as standard equipment.  They reduce the risk of hitting something or someone.  A March 2014 study by the Insurance Institute for Highway Safety showed that back up cameras reduced the potential for accidents involving backing into someone by 90%.  I don’t know about you, but I like that kind of statistic.

So what is my overall opinion of the ZeroEdge Dual-Lens Car Camera system?  I love it!  Granted, by the time you spend the $89.99 for the system and the up to $219.00 for installation, it is definitely an expensive add-on.  However, for those of us who don’t have the means to purchase a new vehicle with this technology built in (BTW, if a rear-view camera isn’t standard equipment, it is not going to be something you can get as an a la carte item, but will be included in an expensive option package).  Oh and if you get yours installed by Best Buy’s Geek Squad, they guarantee the work, and if you get a new vehicle, they will uninstall everything without cost.

  2. My car’s review mirror has all the bluetooth controls on the bottom of it. Will this negate the installation of the ZeroEdge?

  3. Hi Herb. The ZeroEdge mirror is installed over your existing mirror, which completely blocks your current mirror. If you have controls below your current mirror, you would probably be better off with one of the many other dashcams that attach to your windshield via suction cup. I hope this answers your questions.

  4. Hi Herb. If all you are looking for is a forward facing Dashcam, my colleague, Julie reviewed an excellent Garmin model that also included GPS functionality. It therefore recorded information such as speed and position. It is considerably more expensive at $249 but it requires no hard wired installation. It does not, however include a rear view camera.

  5. I have a dash cam in my car and I found it very useful. I was recently in an accident where the traffic stopped very quickly and I was able to stop before hitting the car in front but the person behind did not even brake until way too late. I sent copies of the front and rear videos to the insurance company and they said that after seeing my videos they could not dispute that the fault was completely the driver in the rear car.

  6. Hello Herb – I’ve installed the unit and it appears to be working perfectly, except it is not over writing the SD card. Is there a setting that allows it to do this, or is my unit defective? Hope you can help.

  7. I have used my GoPro as a dashcam at times. Although the video quality is better with the GoPro, it would be nice to have the auto-on and loop recording features. I didn’t hear any audio on your video clips, have you installed a microphone?
    Seeing this makes me miss the Tampa area, btw…

  8. Where we go on the internet for troubleshooting for the Zero Edge Dual Cam?

    My recorded video files only works (default) for the 1 (minute) versus the 3 or 5 (minute) duration if I have my move detect on via the Main Menu. If I remove the move detect the 5 minute file works for both cameras.

    How do you correct the video for the back camera when it records the images in reverse……….. right – left versus left – right video?

    Thanks…………. Sam

    i recently purchased this camera from ebay uk for £30 ,, and fitted it my self in my small van .. instillation wasn’t difficult , but i agree all wiring can be hidden making a much neater instillation , my cables go through the inside of the window pillar and you see aprox 1 inch of cable come from the camera and disappear into the bodywork of the van fitting took around 1 hour . the camera itsself is easy to use and set up and works great . the one down side was the instructions with mine were so small it was almost impossible to read them but i got there 🙂
