Dear,
I'm new here and I 'm sorry if I'm open another topic with same question.
I have two Pelco Spectra III camera both with different camera Head, one has the Hitachi VK-S434ER and the other has the VK-S274ER.
So like both cameras are have FOCUS problem I bought another two head cameras, but I bought the VK-S454ER and both don't work on my cameras.
The symptom is, after power on I just see black monitor and the message Video loss appear and disapear, appear and disapear, all the time.
I think thast this could be something related to firmware issue I don't know but if someone can give me a tip I will be grateful.
Thankyuou for your attention
Best regards
João Santos
