Hardwiring DashCam (Always on for Park Mode)

Post by bg1981 » Wed Jul 11, 2018 1:09 pm

Hi All

I'm a new to me owner of a F21 M135i (63) and wanted to know if anybody has hardwired their Dashcam for parking mode.

I will be using the DDPai M6+ which has a version of parkmode (After no movement it changes to 1 fps and will record if it feels vibrations). I was hoping to use the extra 12v socket under the glovebox but after searching this forum I've found out it's not permanently live.

My queries are if I hardwire straight to the battery, will this cause any issues (Battery Drain and\or errors etc).. Are there any permanent live fuses that I could use in the fuse box.

Or would you not recommend hardwiring it?

Blackvue power magic box, would that work?

I've just looked into this, this is an option I suppose - But I will still need to hardwire this direct to the battery won't I?

Yes or a permanent live from somewhere else.

I have my Garmin 55 hardwired direct to the battery, no issues.

I came across this thread on another forum by a guy who installed a BMW dashcam .
https://f80.bimmerpost.com/forums/showt ... ?t=1220468
I wired my dashcam in exactly the same way ( Thinkware f800) . It has an automatic cut out if the voltage falls below a set point .
Long story short, earth goes to a convenient earth point , always on goes to the Terminal 30 , and the final wire that detects if the car is in park mode or not goes to a convenient termal 15 point. I used posi-tap connectors to connect the wires to the loom at the FEM module ( which always has power available to it).
If your camera does not have a built in voltage cutoff system, you can run your battery flat , so a "hardwire kit" with a voltage monitor in it is needed.The voltage threshold for cut-off needs to be quite high otherwise you can get battery drain type alerts from the car, so choose a hardwire kit with a selectable threshold

I hope that helps you .

Regards
John

How long would it take a dash cam to drain a car battery ?

At a rough guess, I'd expect a recording cam to draw 250mA and a car battery is typically 45AH, so somewhere around 180 hours; about a week. So not a problem under normal circumstances, but you probably wouldn't want to leave it running in the airport car park when you're off to Magaluf for a week.

I've wired mine to the fuse box in the boot;

I have a NextBase wired to the socket under the glove box and it has a small built in battery which remains vigilant for parking issues for a reasonable period.

I've mentioned on another thread, you could consider using a power bank wired to the socket for charging and connected to the DashCam for power although, apparently, you need to be careful which ones you select as some can't power and be charged at the same time.

My only concern with this is a LI-ion battery being stored in a potentially very hot environment especialy the temperatures reached over the last few weeks.

I think I'm going to piggy back onto fuse 126 (Thanks Peter9588) and set the Dashcam to switch off after 6 hours of parking mode. Obviously if this starts to cause issues I will look into the Blackvue power magic box or equivalent.

Thanks for the help guys I will let you know how i get on.

I installed the fuse tap on fuse 126 - All was fine, until I tired to use the stereo (no sound) and then realised the PDC wasn't audible either! So not sure what's going there, removed fuse tap and everything is working again.

In the end I wired directly to the battery, I realised the hardwire kit I has low voltage protection so I think using this and the 6hr sleep function I will hopefully get away without any errors.
