Remember its not just about time, its about how much it'll record, on my drive it lasts all night, at work it lasts 12 hours, but in a busy car park it might turn off for 6/7 hours.
What id suggest is making sure you don't have a parasitic circuit someplace in the car, when the car is fully asleep it shouldn't draw more than a few 10s of milliamps, if you drawing 300mA then you have a problem, no amount of setting changes on the dash cam will help you. Also, 12.7 is edging on the low side, how old is battery?
Finally, what's the weather like? Cold weather reduces battery efficiency and increases consumption
I have the cam disconnected, I'm going to drive it a few days and charge the battery up first then I'll run the test later in the week and keep you posted.Mine sits at over 13 on battery. I think at this point the sensible thing to do would be to test the current draw.
You will need a multimeter, disconnect the positive terminal on the battery (make sure you have your radio code first) then connect the multi meter between the positive terminal on the battery and the now disconnected positive leads.
Do Not attempt to start the car, your multimeter will not survive!
so get a reading of current draw from the moment you remove the keys, then do it again every 10 min for half an hour, by that time the car should be asleep assuming you didn't open any doors or turn things on, the ECU is the main one, that can stay alive for half an hour or even more..
Do that without the dash cam to give you a base line, then try It with the dash cam to compare
As I said, the current draw should be a few 10s of milliamps when asleep, any more than 100mA and you will start having issues, any more than 300 an your going to have some battery problems sooner rather than later if you dont drive a lot..
Okay, I gave it a shot anyway. I used the neg side, it read -0.50 and quickly dropped down to -o.15 and leveled out.I have the cam disconnected, I'm going to drive it a few days and charge the battery up first then I'll run the test later in the week and keep you posted.
can you do me a favour and upload the .06 firmware? ive got a feeling that every time ive updated the firmware its got worse, I'm curious how you got on with the new hardware and firmware.
video quality is very good. but more important , this cam is just much better built
than the competitors in the same price range. (I've owned 3 blackvues which all
had overheating problems)
If you get the thinkware hardwire cable with it & hook it directly to the batter
you get the parking mode functionality as well and you won't need a power unit.
Are there cameras out there with better video quality ?
I'm tossing up if I should buy now or wait for the F770
