Advancedbikers Camera set up - Sony Camcorder and Drift HD with Autocom

I always get asked time to time, what is you camera set up ?, how do you connect the Autocom to the camera ?, how does it work with the Drift HD ?
Well here goes, but I must warn you I am no technical expert in this field and the latest set up could not have been achieved without the help from Andy Griffiths and the Griff Gizmo !

The present camera set up consists of three bullet cameras, connected to a Sony Mini DV Camcorder with the AV in facility.  These units are getting harder to find and cost a fortune to repair, so I am gradually experimenting with a Drift HD 1080P camera. 

The front bullet camera is fitted with a Ram Mount to the offside of the BMW beak and is a 600 tvl version.  The bullet camera is clamped to the Ram mount with a Ram Pipe Clamp.  It is also fitted with a sun shield.....Just in case it gets sunny.

The bullet camera has been a great bit of kit but does take a bit of setting up with power and leads etc.


The second camera is fitted under the rear carrier and again fixed with Ram mounts.

The other camera I mentioned is helmet mounted with 3M.


The next task..... How do you control all the cameras....Just add a switch to the handlebars, bottom one, front and back cameras.  The top switch switches onto the helmet camera, giving me helmet camera and from camera.




 
The BMW R1200GS is 'Hard Wired' with phono sockets for the camcorder lead and has a lanc fitted for pausing the Sony Camcorder.  


The Sony Camcorder is placed in the Tank Bag


The biggest problem I have with the Bmw is storage, so I fitted a Pelicase 1300 to replace the pillion seat.

There is a power supply to the case and I have put a 12 volt switchable constant supply in line with the power supply to the cameras and run them on 9 volts.  The plug you see in the fron powers the cameras.
So you see a complex set up......But there are a lot of other cameras on the market - High Defintion...... Go Pro, Drift Hd etc...
So at the beginning of the year I took the plunge as Action Cameras were offering the Drift HD 1080p camera for £150.00.  I managed to get 10% discount so it came in at £134.00.
I first used the Drift HD when I went to Spain and had it helmet mounted :


Not the best attempt - Unable to get the right angle....... BUT I did invest in an additional power pack from Ebay and it gave me power all day.  Details below

 The next task - Audio....

I have Autocom fitted and there is an external microphone you can buy and it fits the Drift Hd 1080P.


However I did not fancy having an extra cable to my helmet and fitting two microphones into the helmet did not appeal to me.

The next thing that happened was a friend of mine, Andy Griffiths had the same idea and was looking at a way to connect the Drift Hd to the Autocom.

He came up with the Griff Gizmo.




Advancedbikers ‘Griff’s Gizmo’ - Instructions for use
 
Purpose of Unit
To take both the riders voice signal and bike to bike chatter from Autocom Bike communication units and record them on to the sound track of a Digital Video Recorder with a microphone level input. This unit has been tested with Autocom and Drift HD Cameras only.
Further Parts Required
·         In order to get both rider’s voice and bike to bike sound recordings on to a DVR soundtrack you will also require an Autocom Headphone lead, part number 2091A.
·      You will also require a stereo jack to jack lead to connect from your Gizmo to your DVR, one end being a 3.5mm 3 pin stereo jack plug (Griff’s Gizmo end) to whatever corresponding size the DVR unit Jack socket is, on Drift HD units this is a 2.5mm 3pin stereo jack plug, on a Drift HD Ghost it is a 3.5mm 3 pin stereo jack plug. (You can use mono leads, but stereo are more readily available and cheaper).
If all you require is riders voice output to DVR and you have a post 2009 Autocom system then you do not need the Gizmo, you can simply make a pin to pin lead from the 4 pin 3.5mm Autocom jack to a 2/3pin Jack of corresponding size to your DVR input jack!




Connection Details
·         Connect the Autocom 2091A lead into the Autocom Pillion 7 pin plug, (if you still want to connect a pillion passenger you will need to obtain an Autocom splitter lead).
·         Connect the Stereo Jack plug from the Gizmo into the headphone socket of the Autocom 2091A.
·         Connect the Stereo jack to jack lead from the Gizmo jack socket to the DVR.
Do’s and Don’ts
·         Never connect directly from the Autocom 2091A lead to the DVR without the Gizmo inline; you may damage your DVR!
·         Install the Gizmo in a fixed position adjacent your Autocom unit, although the leads are flexible I have had instances where over flexing of the cables has broken the conductors, fitting the Gizmo in a fixed location removes this problem.
·         Position the Gizmo and its leads away from any power cables to minimise interference pickup.
·         If the Gizmo fails do not open up the unit, it is filled with liquid plastic to keep the components corrosion free, opening it up may destroy the unit, please return it to me so I can ascertain the reason for the failure.
Tip’s
·         I have not found a stereo jack yet that will plug into the Drift Camera weatherproof cap, you will have to sand down the plastic of your jack plug to make it fit through the weather proof cap of the Drift, it is easily done.
·         If you still have older camcorders that take a line level signal you can easily connect them from the headphone socket of the Autocom 2091A without the Gizmo in line using a lead such as Maplin Twin phono to stereo jack lead part number N04JZ.
 



 



The Autocom 2091 connects to the pillion lead, but my pillion is connected to my Sony Camcorder, so I made the splitter lead up that feeds off the riders socket.

How to get microphone level signals out of an Autocom system
Ok Guys I’m not an electronics expert, but as I couldn’t find the answer to this whilst I was looking, I thought I would share what I had found out.
I have been looking around for a long time now to see how I could get sound out of an Autocom System and into the microphone input of the new modern DVR’s. Not just the rider’s microphone but also the background chat from bike to bike.
Spoke at length to Autocom who didn’t really manage to give me a full answer as to how to do this, they gave me some bum advice along the way (they tried to be helpful but I just don’t think they know fully the products bought off of the old Autocom team), but they did give me some good advice about the sound output (speaker output) from Autocom. So in the end having done a lot of research online, I decided to risk making and connecting up my gizmo and hope I didn’t blow the Microphone input of a Drift HD Camera unit.
To give an example as to why you might want to do this, if you’re an instructor and you have the microphone output only connected from Autocom (available on all post 2009 Autocom units on the 3.5mm 4 pin jack), any video on the DVR will only record the instructors commentary, if your student or mate is also wired for sound and you can feed in the speaker output you will also get their commentary on the video.
The other reason for wanting to do this is that over the year’s camcorders / DVR’s have developed. Going back quite a few years most camcorders used to have line inputs, the red and white mono Left and Right ‘RCA’ type plugs, the point being most kit had unbalanced line level inputs, whereas the new action camera gear and Digital Video Recorders tend to have microphone inputs only.
What’s the difference?
Microphone inputs work at voltages of up to about 3 to 4 millivolts and line level inputs work at voltages up to about 700 millivolts. So if you put a line level signal into a microphone input such as on a Drift HD it could damage the circuit board.
So before messing about with the Autocom too much I first made up a simple pin to pin lead just to take the microphone output (riders voice) from Autocom to the Drift HD (remember the microphone output from Autocom is already at microphone level so doesn’t need reducing). This worked fine.
First a few things the Autocom guys did tell me,
·         The speaker outputs from the Autocom 7 pin wiring harness are balanced audio outputs. That means you have a separate positive and negative connection for both Left and Right speaker outputs +L –L, +R –R.
·         The speaker outputs don’t work at line level all the time as the signal strength changes (it does on the SPA) depending on noise conditions and the 40% reduction in sound when the microphone kicks in. Might have to check your dip switch settings dependent upon which output you use.
·         Post 2009 Autocoms already have microphone output from the 4pole 3.5mm jacks (rider’s voice only).
·         All other connections on the 4pole 3.5mm jacks are audio inputs not outputs.


I put my wiring into the handlebar bag and the additional Autocom wiring is hidden under my tank bag.


 Time to use the Drift HD Camera and it comes with wireless remote.......
 Micro SD Card adapter, which gives me the ability to view the footage on computers, laptops and some televisions with USB sockets

 

But there are no televisions when I am out on the road training, so I thought - Tablet with Micro Sd Card input.  Yes they exist so a Versus 7 Tablet was purchased.  Found this one for under 
£ 90.00.
This picture shows some recent footage of a recent visit to Dorset.
