Previously I found this post https://amcrest.com/forum/viewtopic.php?t=8003#p18067 where the info Melvin post says the image sensor in the IP2M-854E is the IMX290 but that conflicts with the specs page https://amcrest.com/amcrest-prohd-1920p ... 854ew.html:
Not to mention this camera has been unavailable for months.Featuring the latest Sony IMX322 progressive scanning image sensor and the Ambarella S2Lm chipset, the Amcrest UltraHD camera soaks in the entire scene, dynamically painting all the vivid colors and rich imagery, pixel by pixel, onto your computer screen or smartphone in full 1920x1080P resolution at 30 frames per second (FPS). No need to strain your eyes, lean in close, or play the guessing game when you have this level of detail.
Does Amcrest have another camera with the IMX290 image sensor or do I need to look to other manufacturers?
