I know this forum is more for the Hikvision mainstream products, but I did ask a question here a while back (can't find it now!) regarding Hilook cameras.
I have two of them - a PTZ-N2404I-DE3 and a PTZ-N2204I-DE3. Both were running 5.5.6 firmware. The 2404 was branded Hilook in the firmware, and showed a model number, but the 2204 had a blank space where the HiLook logo should be, and the model number box in the web interface was blank, so think this was an OEM camera
