s_rsadat 0 Posted June 23, 2015 Hi I have purchased a Samsung SRN4000 NVR. The problem is that this SRN4000 automatically resets about every one hour and date and time are changed to the factory default values after each reset. I even changed battery of SRN4000 mainboard but the problem was not fixed and there is a battery warning alarm too. Could anyone help me? I am amid start up a project and this problem has hold everything. Thank you and BR Share this post Link to post Share on other sites

MaxIcon 0 Posted June 24, 2015 Sounds like you may need vendor support on this one. I ran Samsung/Techwin DVRs for years (still have one in service) and they were very robust. Since this is a rackmount, I'd take a look at if it's got any standard PC items, like power supplies or memory. I find that random reboots are frequently caused by one of these items. If it were a PC, I'd start by disconnecting everything possible, then adding them back one at a time. Start with hard drives and memory (if it's standard modules, and not soldered in), leaving in just enough to start it up, then see if it reboots. Likewise, if it uses a PC power supply, you can replace that to see if things improve. The other trick I use for random reboots is to leave a camera watching the screen so I can see what happened right when it rebooted, in case there are any useful errors or messages.
