I am a new user and have been seearching the forums for the answers to my questions without success. I will welcome advise on how to better use the forum or direct answers to my problem. I have two Hikvision DS-2CD2032F-I cameras that were purchased from two sellers on Amazon. Both were purported to be "US Versions." Both installed fine and recorded motion activated video to the SD cards inside for a year and a half. Recently, they have been crashing. One is on the default IP address, the other is on a different IP address. Both Cameras are on 5.3.0 firmware. Both end up back on the default IP address and, of course, that won't work! I would upgrade the firmware if I could find the correct version for these cameras. Any suggestions on what I should do would be greatly appreciated as psychiatrists are very expensive here in SW Florida. Thank you!!!
