    Big fat bundle of coax. 80 cams installed What next?

    Reduce 80 cams to thin cable I guess there are two way would be better, one is twist cable or fiber cable. I would like take fiber cable personally. Then, for Redundance, which is incoporate NAS or RAID something to back up. As for clip function which depends on DVR and/or NAS functions.

    HD-CVI, AHD, HD Analog ?

    Nice sharing. But as I know that not really true for some information. I.e. those three all able to triplex DVR HD+Analog+IP which dependss on manufacture stragtegy on price and market promotion. Yes AHD is developed by Korean Nextxhip for beating CVI and TVI. With regards to optical qaulity, which depends on which brand, size and type CMOS to deployed. Most CVI sensor seems is China made so which not well to compare SONY and APTINA. More tricky is I found some supplier offer 1M camera for lower price to catch your eyeball.

    Dahua HD-CVI systems

    Hello Folks, Nice to hear from you share this valuable info. Actually, I also wonder how is CVI, TVI perform all day. I have seen those perform well at day time but bad at night/dark time. Especially, I found if those stuff install at car moving site, the car will appear streaks(draging shadow). Futher more they claim transmit distance upto 500M, I really question does it true?
