I recently got this camera sensor ttp://www.aliexpress.com/snapshot/7293055509.html?orderId=72676672140705

It is a 1/3" NVP 2421 CMOS + Panasonic 34227 DSP. I have bought sensors like this one in the past and I never had any problems but with this one I get this weird digital noise with either the SDI or the composite signal. I can still navigate through the menu, I have reset the settings switched between PAL to NTSC but it stays the same.



The store is not being of much help, they only offer partial refund so I am hoping that maybe I could fix it.

Any idea on what that would be?

Thank you so much!

 

 

Try a visual inspection of the soldering. Look carefully around high pin count chips. Unfortunately, there is a chip that looks like a BGA with no exposed pins

 

Me thinks it's broke.

 

Hi.

I think you need a lens.

From product page:

2) Lens is not included in the package, you can choose them from our store per your need.

 

Hello,

As nerdegutta said, you will need a lens.
You can see the holes next to the sensorchip.
Those are for mounting the lens fixture.

It's a job to tell from the pics, but the soldering on some of the components looks less than perfect. If a decoupling cap somewhere had a dry joint you might expect digital noise breakthrough.

Camera without a lens produces just a big blur, this camera has other issues.

 

The sensors or electronics could saturate with ambient light. Try putting the camera in a very dark room or cover the sensor and see if the results are the same.
