cameras are fitted on the -300 as well."
That's news to me
Which airline has them on their -300s? The taxi camera system (TACS) was introduced on the -600 in the tail-fin and behind the nose leg to aid in the taxi of the much longer airframe. I was not aware that they were offered as an option on new 300s and further more I cannot see why an airline would spend the extra money when they were not required.

P.S. There is a In-Flight Entertainment system camera that can be fitted to Airbus aircraft showing an external view, but again I do not believe these are recorded due to bandwidth limitations.
