This camera records in 1080p both inside and in front of the vehicle. It records to micro SD card and creates a new file (one for inside and one for outside) every 5 minutes (configurable), deleting the oldest file as the card fills up. With a 64GB card, this equates to about 5 hours on the card, and it can accommodate a 128GB card.
We like the added peace of mind that if there is ever an accident, we have a record showing where we were, how fast we were going, and what was going on inside the cab (paying attention, etc). Note: this camera is strictly for security purposes. We have a different camera for recording for our videos. See: changinglanesrv.com/faq/?Display_FAQ=1752
