Hopefully I have posted correctly this time! Signed up to this forum as there seem to be some very knowledgable and helpful people here. I have two Hikvision cameras both PoE and both connected to a QNAS NAS (using Surveillance station) on my network. Router is a Netgear BR500 and usual configuration done via Surveillance station or lately SADP on a 2017 IMAC running 10.14.2 . Cameras working for 2 years with no issues recording 24/7 and remote viewing via QNAP service In early December one of my cameras - Camera 2 stopped being available to view the image online. Further investigation showed that the camera was no longer accepting the admin password (which is the same on both) nor the default or any other I tried even though I know I had not changed it. Eventually got to HiK support and lady called Cathy Tang who exchanges an XML file with me most days. Unfortunately when I use SADP to try and reset the password I always get 'Device Denied'. Support just keep asking me to send another xml. SADP can see both cameras and IVMS can too (as can using safari IP address) so it is there. SADP shows DS-2CD2342WD-I and active at the IP address I reserved for the camera. Port shows 8000 and firmware V5.3.8 build 151224 plus MAC address a start time (now 2019-01-06 16:41:29 as I unplugged it.) I also have DSP build V7.0 151027. Interestingly the other camera (DS-2CD2042WD-I) displays an IPv6 address and IPv6 prefix length (as well as IPv4) whilst this one is blank for IPv6. Both show port 8000 and HTTP port 80 (although noticed ports 9010 and 9020 are open in UDP for both cameras as well as 554. I provided the SADP screen to the HIK support a few times and the serial number exactly as on SADP. They did ask for the time on the camera which obviously I had no idea as I cannot access it. Apologies if too much information but I am really stuck on what to do. I am considering just getting up a ladder removing the camera and sending it for recycling. maybe buy a different make of PoE camera. I have tried asking questions of the HIK support but they just ask for another xml file. Anyone help me? Please note I am ok with network stuff but need guidance on anything unfamiliar. looking forward to chatting with some of you.
