I have posted in the camera section but wanted some feedback from A4 owners that have either installed this system or had it installed for them . If you had it installed then can you say who and were this was done ?? Thanks in advance. Since posting this I have done a lot more digging around and have found the following :- The front camera is 1080p @ 30 fps The rear is 720p @ 30 fps There seems to be some questions over the bit rate of the recordings and the sharpness of playback, also there is a now known issue with interference with DAB radio as the rear camera av cable is not shielded. I am hoping that Blackvue change the AV cable two one that resolves the interference issue and releases a firmwear update to deal with the bit rate question. Having looked around a lot this week this system seems to be very well designed and on paper has very impressive specs but just needs some fine tuning.
