Has anyone tested board type cameras based upon IMX 178 or IMX 185 and sold on aliexpress for USD 100 ?
IMX185 will be better for low light. There was a pic posted before which compared it to the 178 and it was clearer. I don't think anyone here has had a camera with IMX185I don't blame Stonewatch for not wanting to read through 34+ pages of comments that don't necessarily answer the question.
I'm looking for real-world experience with the IMX178 vs IMX185 in terms of absolute low light performance. I'm looking for a camera which can observe weather at night with no IR illumination. Absolute sensitivity is more important to me than resolution.
There are a million cameras listed on aliexpress but there is so much cheating or sprinkling of random terms and figures it's hard to tell what you're really looking at. For example I've seen the IMX185 listed as .0001, .001, .01, .05 LUX. I've seen the same camera from different sellers listed with four different analog or digital interfaces and with no interface other than IP. In short, I don't trust anything I read on the aliexpress site.
So at this point I too am asking has anyone actually tested and compared (not just quoting me specs) the IMX178 with the IMX185 and have an opinion one way or the other?
Based on this spec, the IMX225 sensor cameras have "Sensitivity (F5.6) 2350 mV" which is almost twice the low light sensitivity of IMX290 with "Sensitivity (F5.6) 1300 mV". IMX185 has "Sensitivity (F5.6): 1120mV", and IMX178 has "Sensitivity (F5.6): 425mV".The data sheet imx290 best in low light conditions( more sensitivity ) , but the image quality is not as good as 178 and 185
