I asked about this 6+ months ago on another (“GoPro”) thread but since it didn’t lead to anything useful, I figured I’ll give it another try on dedicated thread. I’d like to find a simple and easy-to-use small onboard "camcorder"(?) with following features/functions: - Battery operated (rechargeable ?), as one of the intended vehicles has positive ground, 6Volt electrical system & no power source available for (modern) electronics. - Good image resolution and stability. Recording often at higher speeds on twisty secondary roads. - External/remote microphone (wired or wireless) that can be placed anywhere in the vehicle, i.e. engine bay, trunk, under the car or dash, etc. - Direct remote control (wired or wireless) for easy "on/off" while driving & without a need for “smartphone”. - Direct re-play (with good screen ?), delete/editing and possibly resolution adjustment that can be easily performed during roadside stops, would be very nice to have. Apparently GoPros cameras don't have some of these, especially external microphone (which is a must). Sony HDR-AS300 has all but any of the last options, but is surprisingly complicated to operate (while driving) and seem to wear out batteries quickly. Also, does anyone have simple advise how to easily(?!?) compress/convert footage shot with aforementioned Sony to easily email attachable resolution by using iMac Pro ?
