Harry02 0 Posted September 22, 2014 Hi Gurus, I just purchased 4 GVI AHP-3136S (new) PTZ cameras. I am hoping that they are good quality. If not, I have 30 days to try. I am a newbie in this field. I need some help on how to move forward on this. I am hoping to avoid the DVR controller. Can I really? If I do, I have some questions. 1) I have home built 12 TB NAS. Can I record the live video on to it? 2) What software should I use? Your help is much appreciated. Share this post Link to post Share on other sites
