As I have said before, I was disappointed that the UK will not get this (at the moment, maybe on future vehicles) and I was surprised that an additional battery was required (would have thought that it would use power from the traction battery), it was more for convenience really as the cameras are already on the car, I will just fit my dash cams as I have done on all my other cars.
I do wish though that car manufacturers would add a USB Socket next to the rear view mirror to make getting power to dash cams easier (I believe Skoda do this) a really useful simple addition.
Apart from tesla, Citroen are one of the only manufacturers to add a dash cam (BMW add accident recorders in some of their cars, not really dash cams)
In the UK, the Citroen C3 and C5 Aircross SUV has a dash cam option called ConnectedCAM Citroën. This is a dash cam that is built into the rear view mirror and is marketed to those who want to either record their journeys, but also to improve driver safety. It has wireless capabilities allowing access to the footage with a smartphone and allows you to share your footage to social media.
Interestingly, I see it marketed as more of a “share your moments” device than anything. In order to record anything, you have to long press the button on the mirror for it to record for a minute. You can then post it to social media. If an impact is recorded, it saves 30 seconds before the accident and 1 minute after.
The system features a 120 degree wide angle, a GPS, and internal memory of 128GB. It records in 1080p.
Besides the UK, Australia Citroen recently decided to the drop this option going forward as they found it wasn’t selling as well.
