QHY2020 supports 21 5FPS,25,35FPS frame rate and HDR two channel output. It has the capability to output dual channels as 4096 x 2048 with one channel at high gain and one channel at low gain. You can also select either the high gain or low gain output.
With read noise as low as 1.6e-, this camera can capture photons from very dim objects. At 3.5 electrons it can achieve SNR=2, which means 4 photons. This detection limit is close to some EMCCD cameras.
The standard version of the QHY2020 is USB3.0. It can produce a maximum frame rate of 33 frames per second for single channel 12bit images, or 21.5 frames per second for dual channel 12-bit images (HDR mode). The camera can also transfer selected regions of interest for extremely fast rates, e.g., 450 FPS at 128lines, 1460 FPS at 32 lines. This specially addressed line readout mode can also be customized.
