quovadis 0 Posted September 12, 2016 Hi All , bit of a shot in the dark .. got one of these units and everything works , except the hard drive ... it goes to boot then powers down , goes to boot then powers down etc ... I check the menu for the hard drive and it has no ID ( Cant be seen or mounted I am assuming ) ...anyway I have a spare PC drive and replaced it with that and the same thing occurs .... any ideas ??. Tried to contact Cnm but they dosnt seem to exist now ... unless someone has a contact ?? ... Checked the boards and all the pots seem fine also ? so I am stuck in the middle of technology unless someone can help or has a spare board or ??? anyway any help appreciated note : the original drive was a seagate and without jumpers ... have spoken to seagate and they say as it was an OEM piece of kit they cant help .....Mmmm stuck again .

ChengXin 0 Posted September 16, 2016 Reflash the CnM's firmware. More likely a corrupted firmware or faulty flash memory in your NVR. Share this post Link to post Share on other sites

ChengXin 0 Posted September 16, 2016 Sorry too many small China DVR players in the market. This CnM does not seemed to even have a website. Get your reseller to help in sourcing the firmware for reflash. All I can find this the user manual https://domar.com/download/CnM%20DVR%20manual.pdf Share this post Link to post Share on other sites
Dekalek 0 Posted May 21, 2019 Hi I also have one of these CnM DVR units and my problem is when I try to create a back up to a USB drive it keeps showing "filesystem open failed" message I've tried three different USB drives all of which work perfectly well in other computers ect Any help would be greatly appreciated Thanks Dekalek Share this post Link to post Share on other sites
tomcctv 190 Posted May 22, 2019 Hi CnM closed down 6 years ago and they never produced anything for 3 years prior to that. How much data are you trying to save it will only load small files .... 10 min or so. Anything bigger you are best connecting via your local network to your dvr by using its local up address. But you will need to set your pc date to 2015 as the active x certificate has expired once the remote view software has loaded you can then reset your pc date.
