I have 2 new DS-2CD2432F-IW cube cameras which I have set up on my network. I have another of the same camera with 5.2.5 firmware which is set up and has worked fine with a 64GB card for a year or so. My problem with the new cameras is that when I install a SanDisk Ultra 64GB card, the audible alarm runs continuously and won't shut off. If I remove the card, no alarm. I have disabled all the alarm settings in the alarms sections. Additionally, when I try to format the card, with alarm blaring, the cameras are not recognizing the card. Does anybody have any thoughts? Thanks
