No, I paid to have it fitted via blackvue, think it was an extra £100 quid on top.
Think one of their cameras has a front and rear view camera combined unit. I've got the one with 2 separate cameras.
The App used to control the camera is a bit of a pain but its regularly updated and the updates are actually pretty good.
My main gripe is that the camera can only record in 1 minute segments so trying to find the right clip can take ages. It does flag each clip with a time date stamp and also the reason it was recorded. I.e if its recorded because the camera sensed outside movement (i.e. someone walking past) or the car itself moving (i.e. an accident) it will be flagged differently and can recordings can now be filtered by the flags.
Also the WiFi signal is weak, It can't play a minute long clip on my phone without buffering at least twice.
