Notification sounds and alerts

Could you please add more distinctive notification sounds, we have doorbell cam and 2 -2K cameras one front and one rear. Current choices are either too similar, or too quiet to adequately inform me on real time which camera is signaling.

Suggestions:

 Driveway or roadway... engine noise,  or car horn

 Rear yard... bird or animal sound

Obviously any creative(destinctive) sounds would be helpful.
