cctv surveillance

I have been using a handful of Uniview Cameras on a HikVision NVR and recently the Uniview cameras have just stopped streaming video. After making a site visit, I can scan and connect to the Uniview cameras, they are still online and I can connect directly to them and stream video via IE browser. When I scan the cameras in the NVR Camera management menu the HikVision NVR discovers the cameras but keeps cycling between "IP Connecting..." to "Offline(IP Camera exception)" I have also logged into the Uniview cameras and checked the hide vendor info box also. It seems as if Hikvision has come out with a firmware that has an issue with these cameras now.. Please give me some more info into this issue... Thank you

Had another 3 systems to reconfigure after being "hacked" this week. Changing the TCP port and 888888 password along with disabling P2P seem to do the trick. I've given a few of my customers step by step instructions to Defualt all settings and unplug the network cable until our techs can reconfigure the network and make the proper changes. At least this way they have cameras visible on their live monitors and if no monitor connected at least the cameras are recording in viewable color not pitch black. Firmware has been difficult to get because 1. A lot of Systems are outdated and firmware is not easy to get for older systems (2015-2016) 2. Support from dist. companies to contact Dahua techs and get firmware then sent to us for flashing takes a few days. In that time we discover more models affected and need to resubmit tickets. Someone mentioned cloud upgrades for firmware. Check out UniView I switched brands last year after seeing their products at a trade show and their NVRS and IP Cameras all have cloud based upgrading capabilities and great products. Someone also mentioned Formatting the HD... not sure at all why you would have people erasing their video ... I would disregard that entirely and DO Not Format your Hard Drive. I have never heard this for any reason other than to erase all video data. Wish everyone luck with their clients in this service filled time.

Assuming so they are rebranded HikVision. So any one have this IP exception error and a fix?

Have you changed all the passwords? admin, 888888 and 666666 included. Do you know how many users you have in the system. You can also check the LOG for User login records and IP that has modified any settings.

Securame is correct, the 888888 is a local admin account. It cannot be used over a network connection. Only from the headend with monitor and mouse. If you don't want to be hacked here are some tips. •Do not use P2P connection, use port forwarding. •Do not use default ports (80 & 37777), create custom ports and forward them on the gateway/modem. •Change your admin/admin password. I've had this happen many times and once I change these 3 things never hacked again.
