I have installed a Low Light camera as well as the Pi color camera so I am streaming both videos to the surface. I am very pleased with the Low light camera. It has a good picture but it works in conditions long after the color Pi camera has lost its picture due to lack of light. Much better than I expected, just as good as some models that run into thousands of dollars. Nice product BR.
@canman172 - Nice! Thanks. I think the low-light performance of that camera is pretty impressive too. We’re working on getting a digital version so that we can get the same type of performance in HD.
From my experience with ROVs the low light is used for navigation and the color is used for close up inspection. I have the low light going to a monitor strictly for viewing purposes. The HD color is being recorded with overlay for inspections and client requirements. The Low light is connected via a regulator board to the battery so even if the system crashed I still have video to the surface which can be an asset if recovering a dead sub to mitigate against pulling too hard on the tether if the ROV is entangled.
Nice to hear someone else likes the low-light SD camera. I was equally impressed with it. In fact in some ways I prefer the simplicity of the “Standard” electronics for the ROV also.
That would be great, a better HD Pi camera for sure.
We are going to run some parallel tests with the Runcam Owl on the Fathom-S along with the Pi HD.
The Owl is similar to the low light BR with 700 lines and 0.0001 lux. Best bench testing and works well. Had it for a UAV setup. http://shop.runcam.com/runcam-owl/
Mark I am powering the camera through a 12Vdc regulator board and running the video straight up 150 meters of tether.
I have a set of baluns which I figured I would need but the picture is excellent without them.
Interesting so just straight analog over the twisted pair? No noise or signal loss?
I’ll have to try that out to compare to the feed over Fathom-S.
I said I would try it straight analog just to see the quality. I honestly expected a lot of noise. There is not a flicker. As for losses I am sure there are some but where I am using the video for navigation the quality is more than sufficient. Let me know what you learn from your experiment.
Thanks will do. Running the Fathom-S its pretty much equivalent as straight out of the camera.
I’ll try and test and take some pictures to compare with it run each way later this week.
