Hardwired h50, worked but drained battery

[davidmathers]

I hardwired my H50 today, and I had it working so it turned on with ignition, then after ignition was turned off it entered parking mode. It worked for a little, but then i noticed after parking for a while, the dash cam didn't turn back on. I checked the sd card however, and even tho the light wasnt on, and the voice disappeared it was still recording. Then Later on i reinserted the sd card and it didnt make a sound or light up. I go to start the car and the battery had been drained. Anyone encounter this or could help?
