jos123 0 Posted September 7, 2016 Hello, I noticed on some NVR from Dahua, when auto reboot is activated it can cause problems. My question is: When this option is set to never reboot, will it cause stability problems? Or not? My own opinion is not, but want to hear toughts/experience from others.

mkkoskin 0 Posted September 9, 2016 Hey, We have had problems with their video servers/encoder in the past. Older models are still required to be on automatic reboot, or they get stuck after a while (could take days or weeks). Newer models do not seem to have this problem anymore, but i believe you just have to wait and see. I suggest you leave it off (no auto reboots) and if you have any problems with it, enable it. If you have to enable it, make sure you schedule it to reboot at night time so it will not do it during busy hours. Share this post Link to post Share on other sites
jos123 0 Posted September 9, 2016 Thanks for your replay. Am installing Dahua products since 1 year, in some cases I disabled auto reboot and had no problem. But this time its a nvr pro with 16 hdd so maybe could be different... Share this post Link to post Share on other sites
dexterash 0 Posted September 20, 2016 Hello,I noticed on some NVR from Dahua, when auto reboot is activated it can cause problems. Maybe the issue is here - and the "problems" can also appear on power failure, network disconnection etc. So, what type of problems? Share this post Link to post Share on other sites
jos123 0 Posted September 20, 2016 Like cameras not getting back on (PoE nvr), or getting "over decode ability" message on the display and not able to see all the cameras. Share this post Link to post Share on other sites
dexterash 0 Posted September 20, 2016 First of all - what cameras? What protocol do you use? Does the same happen if you network disconnect them / unplug cable? Or in the case of a power outage? 1. PoE not getting back on - are you sure your cables are ok? 2. Overdecoding capability... that's another story, but 1st get to the protocol part. [btw, do you know it's decoding capability (Mbps) and you camera's sum?] Share this post Link to post Share on other sites
jos123 0 Posted September 20, 2016 dahua, their own protocol. No, happens sometimes only when set to auto reboot. 1 they work(ed) fine. 2 I know what this is and have only used 50% from the capacity Share this post Link to post Share on other sites
dexterash 0 Posted September 20, 2016 What camera models and what NVR? 1. Yes, but things might go wrong. Including a hardware failure somewhere. 2. Bare in mind to take into account both streams (main+extra) when computing decoding total. Share this post Link to post Share on other sites
jos123 0 Posted September 20, 2016 It's not one specific nvr or camera. 1 its not the first time 2 I have 50% with main so don't think have 100% with the sub Share this post Link to post Share on other sites
dexterash 0 Posted September 20, 2016 Oh, ok! So it doesn't come up at all at power up/power on just only on auto reboot? Meaning, if you set a daily autoreboot every time you will get that error, but if you power cycle it - let's say every hour - it doesn't happen at all?

jos123 0 Posted September 20, 2016 Correct, but not every time. I didn't check, but since I disabled that option problems are gone... So probably a bug. Share this post Link to post Share on other sites
dexterash 0 Posted September 20, 2016 You may be right. Yet, not repeating the same condition, doesn't guarantee it will not happen. A "device reboot" is just that - a reboot. Close to an automatic/unsupervised power down/power up. My opinion is that you will not be very happy with a power reboot hanged in a problem... Share this post Link to post Share on other sites
