Our Review

We adored the fact that it has an internal GPS and high definition recording.  Our recording experience was smooth.  The video quality is great and that is what we loved the most about this device.

You will like the 1080p High-resolution footage of this dash cam as well.  It lets you see the small details of the road and its surroundings easily.  You will experience very few problems with the recorded footage.

Spotting the small details are not problematic and its 118-degree wide-angle covers the entire road.  You can see the recording directly on its LCD screen, which is 1.5 inches.  You will be able to view that footage on your TV or camera.

Cobra provides you free software with this product, which you can use to view location along with G-sensor information.

Still, everything has its drawbacks. Cobra CDR 840 is not an exception.  Included is an SD card but you will have to get a better one.

Pros and cons

Pros And Cons


  • Small in size: Unlike most of the other dash cameras, the Cobra CDR 840 is very small and blends in perfectly with the surroundings.
  • GPS: With live location tracking, your car will always be secure.  The recording will have the footprints of the location which is a magnificent feature.
  • Smart motion sensor: The smart motion sensor in the CDR 840 helps it detect motion in or outside of the car with ease. It is a great feature for those who park their car often.
  • High-quality recording: This dash cam can record videos up to Full HD 1080P that is more than adequate for a dash cam of this size.


  • Comes with only an 8GB micro SD card: Even though you can get a better SD card online, the company should have provided a 16 GB SD card with the CDR 840.
  • Not very rugged: The small and light CDR 840 is not the most rugged dashcam we have seen, and we think the build quality could have been improved.
