<font size=+2>An Almost-Invisible ODY Video-Navi Backup
Camera</font>


<hr WIDTH="100%">
<hr WIDTH="100%">

As others have suggested, one of the many possibilities for extending
VideoNavi's famous <a href="http://www.odyclub.com/ubb/Forum4/HTML/000044.html">"Video-on-my-Navi"
mod</a> is to use the Navi screen as an electronic backup mirror, automatically
displaying the view behind your Ody when the vehicle is in reverse. I decided
to take on this mod.


After evaluating various possibilities for where and how to mount a
backup camera, I decided that the most practical approach was to mount
a little CCD camera inside the vehicle with a view out  the back window.
This avoids all issues of protecting delicate electronics and optics from
the weather.


There are many tiny CCD camera boards available on the surplus market.
I chose the <a href="https://www.jameco.com/cgi-bin/ncommerce3/ProductDisplay?prmenbr=91&prrfnbr=5276&cgrfnbr=852&ctgys=504;554;852;">BC22CML
from Jameco</a> which costs $60.  This is a relatively low resolution
camera compared to others available, but I chose it because it is very
compact, has fairly good low-light performance, and has an unusually wide-angle
lens, which is desirable for this application.


So, how to mount it?  My solution was to mount the camera in the
headliner pointing straight down!

Here's how I did it:


First, I popped off the plastic cover for the rear-seat center shoulder
harness retractor.  I drilled a hole exactly the size of the camera
lens in the part of the headliner normally covered by the rear secton of
this cover. The camera fits snugly through this hole. It looks like this:

The camera requires 12VDC power. To provide this, I tapped into the
backup light circut and fed it to the camera through a 1 amp 12V regulator
(Radio Shack part number 276-1771A). This way, the camera is only powered
when it is needed.


I also tapped into the "backup" signal that is present on the NAVI harness.
I used this signal to control a small SPDT relay that switches between
the normal Video-Navi video input and the camera. It also activates the
4PDT Video-Navi relay. This way, whenever the van is put in reverse, the
camera is automatically turned on and displayed on the Navi screen.


So, you ask, why do I have the camera pointing down with a view of my
luggage compartment?


Glad you asked...


What I did was to use my trusty Dremmel tool to cut out a small notch
in the shoulder harness retractor cover and mounted a small mirror at an
angle that provides a perfect view out the back window. I used a Sears
model 9-4097 inspection mirror and mounted it in place using a glob of
silicone RTV adhesive. The mirror also reverses the camera's view, making
the view throught the screen properly "mirror-like".  The setup looks
like this:

<img SRC="http://www.maya.com/local/avanti/backupcamera/backup2.jpg" NOSAVE height=450 width=600>

 


I ran a piece of thin coax from the video-out of the camera up to the
front and into the relay input.


After putting everything back together, the camera is very non-obtrusive.
It looks like this:

<img SRC="http://www.maya.com/local/avanti/backupcamera/backup7.jpg" NOSAVE height=450 width=600>

 

 


Last but not least, here's the view of my dirveway as seen on TV:

 


<img SRC="http://www.maya.com/local/avanti/backupcamera/backup10.jpg" NOSAVE height=450 width=600>

 


If you look carefully, you can see some almost-horizontal lines in the
lower 2/3 of the picture.  These are the rear-defroster wires embedded
in the rear window that the camera is looking through.


If you have already done the Video-Navi mod, the total cost of this
addition is well under $100. It works great and definitely is an
effective way to impress your friends.

Wozie wow wow! I must have!

That is one sweet mod. Considering (if you have the video-navi already done) its about the same price as backup sensors...

...and as for seeing at night; just install an all-PIAA solution for your rear marker & backup lights!


Great job! Coolest mod I've seen in awhile!

Well, call me your FRIEND because I for one am IMPRESSED! WOW! And the lines on the screen make is look even more high-tech! Plus the fact it automatically switches when in reverse. Perfect.

Great job Avanti on taking on this so long talked about mod! Now you got my eye twitching...

MUST...NOT...DO...COOL...MOD
MUST...PAY...BILLS!
Ahhhhh...

How far behind the bumper straight down can you see in the view? In other words, is the view from the camera sufficiently downward to see significantly more than the view straight out the rear window that the driver would normally see? Could you see another car's bumper when it is within several inches of the Ody's bumper?

I ask this because the perspective in the final shot of the view on the Navi looks somewhat the same as when using the rear view mirror.

You like me. You really LIKE me.


To answer the questions:
--Night vision: This camera has quite a good auto-iris, it does a nice job of adjusting to different brightnesses, which is important for outdoor applications. That said, night vision is still not that great--about what you'd get with an average camcorder. You can see vaguely if you are under a streetlight, but in ambient darkness you see nothing. Practically any light source is visible, though, so you can still detect cars, etc. Nyvram's suggestion of PIAA lights made me wonder how well a super-bright IR LED floodlight would work. Most CCDs are pretty sensitive to IR.

--Visibility: Actually, the last two posts are related: As I mentioned, this camera has a pretty wide-angle lens (better than 90 degrees). This (a) makes my driveway look more impressive than it is, and (b) does a pretty good job of rear visibility. I just did a test with an object 16" high centered in the back of the Ody. Here are the results:
It was just visible at the bottom of the screen when it was 45 inches from the rear bumper. The same object didn't become visible through the rear-view mirror until about 30 feet, depending on how tall you are.

...and best of all, you didn't have to spend 60k+ on a Q45! (Speaking of which; what is up w/ Nissan/Infiniti?? No web presence? What is up with that? I couldn't find an official Infiniti website to link to.)

This is the coolest mod. When do you start installing the 5 other cameras & remote driving control so you can drive your Ody remotely via the web?

I don't know about *five* cameras, but I was seriously considering installing two more of them looking out the side windows to cover the side-mirror blind spots. It would be easy enough to control them via the turn-signals.
But then I came across the following (much simpler) solution to the blind spot problem:

This is a most amazingly effective trick. I highly recommend that everybody try it. It really does work.

Avanti,

Great use of "Video On My Navi". I attempted the same thing, but mounted the camera inside the rear tailgate on the flat area of trim panel. The camera is very difficult to line up because the outside wiper arm and window trim. It also kept coming out of adjustment... the image is not reversed. Your mirror trick is perfect along with the location.

Have adjusted my mirrors like this for almost as long as I've been driving. Some people think it's weird, but it really is the PROPER way to adjust your side mirrors. Any other way really limits their utility!

I have been using this method for years, and it really works. You can see the car as it leaves your rear view mirror, in the side view mirror, so that you never loose sight of the cars comming from either side. This works especially well with the large ODY mirrors.

ditto shinjohn, the mirrors are set wrong in the factory and people have gotten "used to" seeing the side of their car in the side mirrors! I am always amused when I see the little round "Blind spot" mirror stuck on a mirror. That person obviously never heard of the right way to set their mirrors.

Well, I'll be damned. I couldn't get into these sites the other day & Google didn't turn them up either. :[


Oh well, I guess I imagined it...
