With todays dash cameras from stand alone single forward facing, to dual outward facing cameras (both front and back) to high resolution are normal expectations.
More current are the networked versions which are locally networked versions that require a smartphone, tablet or pc/laptop to transfer videos out via applications.
Or the latest which is on Cloud access networked solutions with GPS, power down relay back up solutions (for recording last recording prior to power off), add on microphones, multi camera even for in cabin with optional audio. Excellent for tracking your precious cargo (which could be your family or customers in the case of ridesharing/commercial controlled transport) or just for personal safety.
