Why Should You Have a Dash Cam

Dash cams are mounted onboard cameras in your car that record the view through a vehicle’s windows. Some dash cams include a camera to record to the interior of the car. There are many advantages to using a dash cam, there are four main reasons why you should invest in a dash cam.

Moreover, dash cams can record your entire road trip, you will be amazed by the footage your dash cam captures over a journey.


Different Types of Dash Cam


- Basic dash cam

Basic dash cams usually have a small sized screen that can be used to display and playback surveillance video. It is usually mounted using a suction cup or 3M glue during installation. There is generally no software integration in the device system, and only very limited firmware modules are available to support it. The price of basic dash cam is the cheapest among the four different types.



- Mirror dash cam

Mirror dash cams are the largest car camera, and they are generally fixed directly on the original rearview mirror of the car. With the mirror dash cam, you can increase the original rear view mirror imaging range and replace the rearview mirror with a camera screen. The main downside is seen where the screen reduces the usability of the original rearview mirror. Most manufacturers will also add practical hardware modules such as GPS, GPRS, and tire pressure monitoring to provided additional utility of the device.



- Cloud/Smart dash cam

For those drivers who are really into cutting edge technology, a smart dash cam is a perfect choice. Cloud/Smart dash cams are similar to mirror dash cams but integrate an Android system into the mirror/basic dash cam form factor. The installed software transforms the device into a driving tablet. Cloud based dash cams offer an added level of redundancy through cloud storage but will come at an added premium.
