Basically there seems to bé an initialization issue with thé camera, that fails tobstart properly quitte often depending on thé way it has been poweresld/unpowered.
I am actively looking for other users of this caméra to unferstand if thé issue I reported Can bé reproduced with other caméras of thé same model
If you have this caméra I would bé good to hère from you about thé behaviour of thé camera when powering 12V first for instance.
