hikvision DVR 1080 with NAS ??

[wesam_az 0]

I want to take a backup of my DVRs (9 Hikvision DVRs 1080) ,I'm wondering whether can I use any NAS with my DVRs!!

so if anybody has an idea about this subject can advice me..

I found so many NAS devices , WD my cloud, QNAP , seagate and Synology

 

also want to take your advice about this NAS (Synology Diskstation DS1515+ Series NAS - 5 Bays) ,is it good with my situation

 

and the last question is I 've already bought 5 HDD WD purple 4TB, to use them with the NAS , is there any problem if I use these HDD with the coming NAS instead of WD red???

 

 

thanks in advance

waiting your reply
