Would it be possible to have a different sound for locking the file using the remote button? The camera sound is good, but the very short beep for lock is not easy to hear when you are going fast, maybe a padlock sound, or prison doors locking! Or maybe 3 beeps would be OK.
Also, is it possible to have a shutdown sound on high temperature shutdown? Currently I can hear when it turns back on, but I don't know that it has turned off and is no longer doing its job - if I could hear it shutdown then I could turn the air conditioning up or open the windows to get it working again, it not good to find out that you were driving with no recording. (I haven't changed the resistor yet so mine still stops in hot weather.)
