Back up camera problems and troubleshooting

Okay, so thanks to everyone that helped me with this back up camera process and set up so far. You guys rock

But...... I still have one problem. Why are the little night vision lights (they're little LEDS on either side of the actual camera lens) always on? I remember reading a thread on some forum somewhere else where the guy had the same problem but I was unable to locate it.

Anyone know why?

I have it hooked up correctly..

1. RCA to the head unit - check
2. reverse sensing wire coming from back of head unit wired to the positive (brown) wire on passenger side taillight - check
3. Camera power wired to Amp's remote terminal (12v power)
4. Ground wired to Amp's ground terminal

Steps 3 and 4 were done to save time. it looks cleaner too

The camera works exactly how it should. However it should be noted there is no difference in the function if I switch the polarity (ground or battery).

but those lights... their irritating! why are they always on??? and since I completed the install after dark, i found they cause too much glare causing a poor image!

Any and all thoughts are appreciated and wholeheartedly invited with open arms.

Thanks boys

I answered in your other thread as well, but I'll put it here for "completeness" as well.

If the little LED lights are always on,, that means that the camera is being powered all of the time. That is why most people connect the power wires to the reverse lights - because the reverse light wiring is only "hot" when the car is actually in reverse, so the camera would only be powered while in reverse. The camera itself doesn't know when you are in reverse or not - if it's getting power, it's going to be on.

If you are powering the camera via your amp, then it's going to be on as long as your amp is on, which is not good (it will probably go bad much sooner).

By the way, the whole purpose of the LEDs is to give you a better image at night. Sounds like they don't work very well though. There are two types of "systems" used for "night vision" backup cameras. The first (and original) type uses infra-red sensors to show nighttime images. It actually works very well - even with virtually no light (and my very dark tinted tails), I can still see what's behind me very well. Lately, some of the more inexpensive cameras are using LED's to help light up what's behind you - instead of real infra-red sensors.

I've never used the LED type, but it sounds like it doesn't work so well. It's supposed to make the nighttime images BETTER, not worse. :-) From what you've said, it sounds like the LEDs are just too bright (and the light is not "focused" properly), thereby washing out the camera image....

What type of camera is it, if you don't mind me asking? You can get decent, infra-red night vision backup cameras for under $50.

I love the night-vision backup cameras. It's so cool being able to see behind you in complete darkness! :-)

EDIT: I just found your camera type in one of the many different threads you started about this (makes it hard to follow when you have so many different threads on the same topic!) - I have a feeling that the camera image is getting washed out at night because of the cars license plate light, not the lights on the camera itself. I had this same issue when I installed my full-frame license-plate backup camera. The solution is to put the camera at the bottom of the license plate instead of at the top. With the "bar style" cameras like you have, you'll have to add fasteners to the bottom of the plate (8th gens only come with screws at the top of the plate instead of all 4 screws). @TSS did this to his - he might have some pointers.

In my case I have a full-frame backup camera, so I just installed mine upside-down (and flipped the camera around to compensate) - completely solved the issue.

Makes sense. If I wired it to the tail light instead of the amp, though, would I have been able to turn on the camera whenever I wanted? Or only in reverse? Right now I can go in through my head unit and turn the camera on when i am not in reverse if I want to, and I like that choice.

IF I were to wire it so it were connected to the tail light, Im guessing the camera power wire would go to the brown one and the reverse sensing wire would be moved to one of the 2 black wires?

and my bad! on another forum I used to belong to they were super strict about starting new threads for new questions! I'll cut down on my creating new threads.

Thanks for your help!

You are correct - if you power the camera via the reverse-light wiring, it will only work while in reverse. But it's either that or the LEDs will be on all of the time (and I imagine would burn out MUCH quicker). WIth that type of camera, you really don't want it powered all of the time. I understand that it's kind of cool to be able to view the camera at any time, but in reality, it's really not that useful if you aren't in reverse. :-)

Here is a picture of the reverse-line wires that you need to connect to, if you go that route...

Thanks! So the Positive goes to the brown, the reverse sensing goes to the middle black, and I'm assuming if I wanted to I could hook up the ground to the far left black wire?

Actually, again, with the Rosen and my backup camera, I connect the camera positive wire to the reverse-light brown wire and the camera negative (ground) wire to the reverse-line black wire right next to it - that's it. I don't connect anything to the car frame for grounding or anything like that....

And this is how others have done it as well (even for non-Rosen head-units). I have no idea about the "reverse-sensing" wire. I don't recall reading others needing to do that part. THis picture is actually from another thread on this forum. Let me find a link to that thread - maybe that will help since it wasn't a Rosen plug-and-play unit.

Well, here is the link, but it's not much help. One post does mention that he needed to run a reverse sensor wire from the BCM to the head-unit, but doesn't say where it's connected to exactly. :-)

You might want to search the forum a little more - I'm sure this has come up before...

I think you are correct for your unit... but since mine has a reverse sensing thingy, that is the wire that needs to go to the ground. The camera's ground just goes to the frame.

I think?

How else would it know?

Or....... does the reverse sensing wire and the camera positive get attached to the same brown wire in the tail light? And the ground is just the ground.

Im gonna try that.

Ill have the fire department on standby.

My *guess* is that the reverse-sensing wire needs to see 12v - if that's the case, the yes, I would think you'd run the camera positive wire and the reverse-sensing wire both to the reverse-light positive wire.

It's completely up to you, but you can also just run the camera negative (ground) wire to the black wire on the reverse light as well - it's grounded to the frame somewhere as well. Either will work. Most people just run both positive and negative camera wires to the positive/negative reverse-light wires (just easier to run them both to the same area).

Awesome! Glad to hear that you got it all working. Backup camera *is* nice to have. I never thought it was all that important with a car, but I LOVE having it now that I've gotten used to it.

Did you move it to the bottom of the license plate as well? Just wondering how the LEDs are working when the camera is being washed out because of the license-plate light.

I actually did not, because I cannot get a bolt to go through on the bottom. I can't get my hand behind the bumper

How does the night vision work - still not good?
@TSS - do you have any tips on installing bolts at the bottom of the license plate? I'll probably do this myself at some point...
