Weird display issues w/ Qsee camera when connected to TV AV port

[TT_Vert]

Not sure if this is the appropriate place for this but I don't see any camera section. Basically I just got an RV and am replacing the zoom camera that sits at the top of the roof. It's a BNC camera but has no brand. It works fine in the AV port but zoomed too far in so i'm replacing it. The replacement qsee camera continually seems to scroll and look distorted with a changing frequency when moved (See video). The same thing happens w/ other bnc cables/cameras. I have a ton of new Analog Qsee QTH503B cameras. The odd thing is that when I try to use the AV (yellow coax) port it shows what you see in the video. I have tried different bnc cables, different power adapters and also different cameras. All produce the same issue. HOWEVER, if I plug it into the Component Y port it will show perfectly but only in black/white (when switching input of course). So I know the AV port is fine, the camera is fine (displays in component), the 12Vdc supply is good and the BNC cable is good. I am using an RCA to BNC adapter to do testing bypassing existing wiring but the problem persists. I also wired power right to camera to take the 50' of power cable in that bnc cable out of the equation. I have gone through the TV tos ee if there was some setting that could cause this and also defaulted the TV to factorty defaults just for the sake of argument. I know I can convert BNC to HDMI but I don't want to add more devices. I am going to try to plug it into another TV AV port today (if I have any TVS with one anymore)



Any help would be greatly appreciated.

Your composite RCA port does not support the HD output of that camera...
I have a few that is like that. Regular composite RCA goes up to 480x480 or 560x?? so any newer analog camera that goes up to 720P or 960 or 1080 it will display distorted pic. Camera is probably fine. If you have a component video jack on your TV you can try one of them without color... I tried the green one and it display black and white pics on these camera.

or you'll have to go find some down converter if you still insist in using that camera.

The thing Is I have a 1080 license plate camera that works fine on that port. So unless it's somehow down scaling that particular camera I doubt that is the issue. And I did post above that plugging into the Y jack does give me a B/W image.

that camera is either automatically down scaling or it is not a true 1080P....

like I said, I have few 720HD and 1080P analog camera that my DVR does not support and does that same thing when I plug it to the composite ports.

That's so strange but makes sense. I purchased THIS RCA to HDMI adapter, maybe it'll help.

BTW, just checked and were actually 960 for this backup camera

Effective Pixels: 960*576

Plugged it into my HD LG Plasma and it does the same thing so it has to be something w/ these Qsee cameras at this point when trying to use RCA. Could it be this BNC to RCA adapter I have perhaps?

Also just found this, although mine is 1080 I assume this may still hold true.

IP cameras can not be connected directly to the RCA input as you have already figured out. This is because the video signal of QSee 720p cameras is not an analog video signal. Qsee is using one of the HD-over-Coax standards for these cameras. HD-over-Coax security cameras need to be converted to an HDMI signal in order to connect to a TV. We need to help you find out which video standard your particular cameras uses so we know which of these HDMI converters to recommend to you.

Confirmed it's the camera. I got another camera today from amazon and it works fine w/ this RV TV. Problem is the OD is too large to fit my housing. I'm going to keep trying to find one that had the OD I need or smaller.
