It's a Chinese domestic model, DS-3CD3T86 . It's designed to shoot objects thrown down from the tall buildings, no IR or white light LED integrated, it only works with the street lights
Don't know if there's a re-named English international model, if you see a Hikvision model with a 1/1.8" 8MP CMOS, very likely it will share the same hardware with this one
SoC: Novatek NT98528(G5 platform)
CMOS: OmniVision OS08A10, 1/1.8" 8MP, pixel size 2.0*2.0um, which is a little small for low light environment. Similar CMOS with the same specification is the Sony IMX334, but I haven't got one yet.
Lens: 4mm F1.0 M16 mount, with fixed IR filter, no IR-CUT
RAM: 1GB
ROM: 128MB
Max resolution: 3840x2160P@30FPS
Shutter speed: 1/1-1/100000"
There's nothing to review in daytime when there's plenty light, image is pretty good thanks to the 4K high resolution, so I will compare its low light environment performance with the 2MP Hikvision IMX385 box camera in totally dark room.
The two cameras are locked in my storage room with no window, the only light source is from my Sylonogy NAS, UPS and network switch status LED. It's almost totally dark, hardly anything visible with human eyes. I took a picture with my iPhone 12 Pro in auto mode
Picture with 1/50s shutter and 100% gain, OS08A10 left, IMX385 right, in both color and B/W mode:
Following are pictures with 1/12s shutter, 100% gain
Although not as good as the IMX385, the OS08A10 still has very good performance in low light environment, especially when considering its small 2.0*2.0um pixel size, which is almost only 1/4 the size of the IMX385's 3.85*3.85um
It's always the bigger the better
