HDD is full and failed to record

[Samee]

Hikvision ds7608ni-e2/p with a Nas attached Qnap ts-131 with a 4tb Wd purple drive. Drive is now completely full and in the night it seems the NVR rebooted 6 times and with chunks of black blocks where it did not record when it was set to continuous record.

overwrite is enabled on the NVR, is there anything which I could do for it to be able to still record by over writing instead of me reformatting the hdd?

why dont you put the 4TB purple drive into the NVR instead of doing this NAS crap? Hik's track record w/NAS storage is less than stellar from what I've seen around here, I would avoid it unless you have no other options.

My reason for doing this is because where the camera system is being used nobody lives there and goes there that often, so if somebody decides to rob the place they can take the NVR but the footage will not be in recorder. so at least I would have footage for the event. Also it's hidden in a different part of the building far away from the NVR so it would be hard to find.

ok, i understand your reasoning.. but I think your doing it wrong.

put the purple into the NVR, record there.. put a smaller HDD in the nas and have it save the last day or so's video there.. your system will not be dependent on the NAS and you'll still retain the capabilities you desire.. if your nas gives you trouble every week and you have to reformat it, then its not going to do anythign to your recordings.. its just acing as backup. otherwise you have made a more complex, thus more failure prone setup to try to defend against just one unlikely scenario.. best case its a wash, more than likely you'll end up with a worse system if you keep this design.

you actually wouldn't even need to use nas, a simple ftp server running a cleanup script to delete old files would be enough.. its how I do it, FTP is simpler, easier, and less buggy.. it kinda sucks as a primary method for video storage, but its actually pretty damn good for backup storage.. you can turn a $20 pogoplug + $30 HDD into a nice hidden backup.

I do have a small hdd in the NVR it's about 160gb which today I had to upgrade to 1tb, as I needed to put the hdd elsewhere to be used.

The NAS has not given me any problems, i had it for 4 months now and the only time I have to restart it is when I do an upgrade of the firmware.

as I have put 2 hdd at separate places I believe this to be a good practice. Is there any issues what you still see with my setup?

yes your still streaming video from camera, to nvr, back out to nas.. and that back out to nas is a whole extra point of failure that has to be operating, and its halving your usable throughput because all the incoming bandwidth is going right back out.. you have a ton of potential for bottlenecks, it wont scale well.

your primary recording should always be local.. put the 1tb drive in your nas and the 4tb purple into your NVR.. Record primary locally, backup remotely.. not vice versa.. it'd be best to have cameras record directly to NAS without any NVR.. so backup does not rely on NVR and NVR does not rely on backup.. right now both rely on each other and they not really providing you with anything but nessicary complexity because your convinced its better than the way everyone else in the world does it.

if you dont have built in PoE, and you do it right.. they can take your NVR and the cameras wll still keep recording to your hidden backup storage long after they believe its been disabled.. thats much better than what you have right now, where once NVR is down all recording stops.. even with hidden storage.

You should not need a ton of storage space for your hidden/backup drive, if you dont realize your NVR is missing and your place been robbed fairly soon then you have much bigger things to focus on before video surveillance.. I think most people would be fine slapping a 64GB SD card into the camera for a backup, if they have enough time to steal the cameras too then there gonna find ur hidden NAS unless you got really damn clever.
