Guys,

Anytime you buy a nightvision camera, make sure it has the blue IR LEDs. That way they don't reflect off the window.

What good are blue LEDs for nightvision?

The blue ones don't reflect off of the window, but still puts out infared. How do I know? I have a nightvision camera laced with 105 Blue LED's.

How do blue led's put out IR light?

LEDs are produced in an array of shapes and sizes. The 5 mm cylindrical package (red, fifth from the left) is the most common, estimated at 80% of world production. The color of the plastic lens is often the same as the actual color of light emitted, but not always. For instance, purple plastic is often used for infrared LEDs, and most blue devices have clear housings. There are also LEDs in extremely tiny packages, such as those found on blinkies (not shown).

To the dude asking about a software solution, check our RRCam here on the forums.

To the "blue LED" guy... You're off your rocker. Good luck driving around with blue LEDS on your dash. It's a great way to get a fine.

If you want IR light, get IR LED's. They are there as an illuminator to make objects visible in the dark. Blue LED's on a camera won't do much more than make you look like a jackass...

You ALL are mis-understanding. Not actual BLUE LED's, but blue IR LED. The kind made with the clear-purplish plastic. Geez.

Maybe this will help "shed some light":

Mount the IR LEDs on the OUTSIDE of the vehicle FTW. If you wanted a premade item, they make IR illuminators for security cameras that can throw IR light very long distances. And, if you're really serious about things like this, go with a siny or JVC day/night security camera. Color by day, black and white at night, with very low light requirements (usually less that .1 lux).

I want to say that this is one of the most awesome things I have ever seen! Good job on this!

Ahhh. See there's a pretty good difference between "Blue LEDs" and Blue IR LEDs.

Indeed. LOL! I violated my own rule:

"Be clear, and specific".

a GPS overlay on that actual video is the ONLY thing that would hold up in court. I don't think that a judge would consider 'comparing' two seperate files to be proof of anything.

that being said, the easiest (and probably the only) way to integrate the GPS overlay into a carPC would be to ditch the webcam and get a standard RCA-out video camera. the video would go from the camera to the GPS overlay device, then into the carPC (via an RCA video input, or through an RCA-->USB video converter). the carPC can then record and/or monitor the video after the GPS info has already been overlayed via hardware. this method has two advantages over software, 1.) since the information was overlayed in hardware it should hold more water in court, and 2.) constant text overlay while simultaneously recording incoming video, running GPS software, audio software, etc. may be too stressful on older/slower machines. since many carPCs are slow by today's desktop standards (mainly to reduce power consumption and heat output), trying to juggle all those tasks at once may be too much for some/most systems to handle.

either way, it doesn't look like it can be done cheap. I've goggled my @ss off and have found only a couple GPS-video overlay devices and they are not cheap (the one that erkme73 used costs almost $200, and the newer model with the integrated GPS receiver costs $285 ). but to be fair, the $200 spent on the device would pay itself back if it gets you out of an exaggerated speeding ticket

For those of us using RoadRunner, there's a great software-based solution. It's called RRCam, and it can overlay any information that RoadRunner can output to display in the skin.

The current release (2.0) is only capible of operating one camera. But the next release is supposed to have multiple camera support. It operates USB cameras.

I currently have it set to overlay GPS Time and Date, GPS Speed, Latitude and Longitude, and heading. Check out the screenshot.
