mes commentaires avec mes quelques connaissances en bleu, si ça peut aider ...
et à ajouter, en other topic, les réponses du support officiel dahua:
Is there a way to reduce the light of the illuminated part (where to put my name label) on VTO2000A ?
--> No we can’t reduce the light, because the light is not very strong
Do you know if it is possible to play records saved on the VTH1550CH from my android phone ?
--> Unfortunately, by now we can’t support playback records, we will try to support in the future.
I tried to use POE switch VTNS1060A to power on a dahua camera, but i does not work.
--> VTNS1060A only use for VTO and VTH, can’t use for network camera. Please use a general POE switch, such as dahua PFS3005-4P-58.
