Night Vision in Car

Perhaps true. My question was for a specific purpose in a location where UV lighting already exists.

Got the camera. Powered it up, decided to press a few buttons.

The result:

Anyone know how to fix it? CS Mount 2.8mm f1.2 130º lens on the way

Tell me about the specifications of your power source... I'm wondering if you are using an AC adapter instead of a DC adapter.

Also, it'll need to be rated at 750mA or more. If your adapter is seriously underpowered you'll be feeding it power that's full of 60Hz ripple.

If it's broken I'll make arrangements to send a replacement!

Mark, is the Nitemax capable of picking up all wavelengths of IR?

The answer is "yes" but it deserves more consideration. You can see that the sensitivity of the CCD drops off quickly beyond the visible spectrum. The trick is choosing a wavelength that's as close to the visible spectrum as you can get without being too visible for humans.

The chart below will help you predict how well this will work at any given wavelength...

AC to DC 9v
550mA

I guess that's the problem. The weird thing is that it worked when I first plugged it in. It just gave me a nice gray screen that turned black when I covered the CCD. Then I pressed a few buttons (gain and IR) and the thing happened as you saw in the video.

Can I power it from my computer's 12v rail?

[Edit]: Removed the adapter, turned nitemax on (screen flashed, then turned off), plugged the adapter back in, turned nitemax on. Its restored to the way I got it. It just displays a grey image. I'm guessing that this is because I have no lens. The image becomes darker if I cover the CCD up with my hand.

one question probably for mark, the cable from the ccd chip print to the lcd print, is that a composite analog output or is it some digital output ?

I have the older avic n1. I want to add the rear camera, and also add a forward looking infrared camera for night vision. I know the rear camera won't be difficult, just wondering if anyone has ever hooked up a forward looking camera to the AVIC n1. I'm just starting to buy the supplies and need help with ideas.

I have it installed in a 1998 dodge truck. Cummins turbo diesel, 4x4, so I have plenty of places to stick cameras.

Any help would be greatly appreciated.

The NiteMax usually starts up with the IR off. Since the IR draws a considerable amount of power by itself (and based on your description) it sounds like your supply is strong enough to operate the camera with the IR off and the world ends when you try to turn on the IR.

A grey image sounds like the correct answer without a lens.

Composite analog is the correct answer...

lol. the more I read the less I know. Well then I have burned quite a number(40) LEDs, but they still give out light cuz i can see it with my camera. so does it give out light even when its damaged?

Well by hooking up a lens I want to 1- hide the LEDs and 2-get a longer FOV. doesnt a lens make the light travel a longer distance? i donno.
Sorry my questions are so basic. thank you mark and shutgon for helping
