  1. You diagram does not say how all this are powered and you didn't tell me if you accept the extra power cable line solution that i proposed?
  2. Almost every 2megapixel h264 camera produces a max of 6mbit stream, so if you will have a constant max stream of 144mbits from the cameras. Now you can not give power to 24 cameras and to poe switches through one utp cable. Its impossible because cameras consume much more power than ip phones and other small poe devices. Now if you use one utp for network and one power cable for powering the cameras and the switches you will have to buy less expensive switches and you will get 1gb link between the nvr and the cameras.
  3. http://www.hertasecurity.com/en This might be what you are looking for.
  4. There is also a brand called MAZi security that has many oem hikvision products. Their web interface is a dislocated, changed color of the Hikvision original one !!
  5. You can try this http://184.154.51.29/FTP/Luvicom/Luvicom_12.12.0/

    Poor night vision

    Try this. I do not now if this applies to your camera but give it a try. Find flicker control in the settings and configure it as indoor ntsc. If you leave in America try the pal. It might give you more illuminated video at night.

    Dahua firmware

    Hi Dirk_D I can give you the IPC-HFW4300-V2 General_IPC-HX5(4)XXX_Eng_P_V2.210.0000.11.R.20140115.bin IF you want.

    Dahua vs Hikvision

    I agree with most of the other guys here about dahua. But there is a drawback with the mobile application. Dahua's mobile applications sucks, hikvision's new ivms mobile applications are top of the tops. Especially if you have a windows phone 8 device, hikvision is your only option here.
  9. HD-SDI is pure digital. HDCVI/HDTVI/AHD are modified analog signals. So the latency in all this systems is always close to 0. HD-SDI has BY FAR the clearest picture in all this protocols and also the same happens if it is compared with IP Cameras, because of it's uncompressed digital stream. But it has also some severe drawbacks like that problems with interferences which are caused by gsm phones and cell transmitting equipment and the inability to connect them through CAT 5/6 network cables without using super expensive baluns.

    HD-CVI, AHD, HD Analog ?

    It seems to me that the article is 50% correct. That means 50% wrong. The AHD could be the best one, simply because it is most recent. But you may take 100% of comments from survtech. All of them are working hard to improve its video quality and long distance performance. We may expect good results sooner or later. In the AHD part it's absolutely correct as i have found myself working with an AHD dvr. The article is failing mostly on the HDCVI.

    HD-CVI, AHD, HD Analog ?

    https://www.linkedin.com/today/post/article/20140912094320-252393278-let-s-talk-about-cvi-tvi-ahd This article speaks the truth about all this protocols. The most problematic of these 3 standards is AHD by far.
  12. maybe this is what you need http://www.ebay.com/bhp/hdmi-over-cat5
  13. I had that problem too. Ask from dahua the latest firmware and you should be able to get 5 megapixel video at 8 fps, at least that's how i solved my problem.
  14. I do not think so. Btw can you tell what version of dvr site are you using ?
  15. You need the card that i told you before. It's irrelevant to tell me what newer card do. It wont help you. If you have an agp system you can use all ati cards until 98xx series and nvidia cards geforce 2 mx and SIS onboard cards 63x
  16. s3 chrome does not have overlay function. Try the link from ebay in my previous replay.
  17. The best way to find these cards are from ebay http://www.ebay.co.uk/sch/i.html?_odkw=x300&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313&_nkw=ati+x300&_sacat=0
  18. Oh sorry, i meant you need an old ATI (bought by AMD a few years ago) vga card. The model can be one of the following x300 x550 x600 x800 x1100 x1300 1550 . Now for more info about overlay see this http://en.wikipedia.org/wiki/Video_overlay
  19. This card is over 10 years old so its inevitable to be incompatible with new VGA systems. Now in my experience in order to make this card work you need an x300 to x1500 ati card. You must not install ati catalyst or it might not work. The problem with this card is that is using an old overlay video display mode that transfers the video directly to vga through pci bus.
  20. I have installed over 1000 of hik's cards and about 100 dahua cards VEC80XX series myself. The other dvr components (m/b psu case etc) are about the same. Until now i never had a single vec card returned as bad. When i was using hik's 40xx cards i have had over 100 of them returned as bad.
  21. Hikvision are very badly crafted cards, they break down like hell (with the common dsp error to haunt most of our machines). For such small deference in picture quality i still prefer dahua cards by far. Compare the pcb The biggest advantage of hikvision card products are the clients. Hikvison made a fantastic mac client that works only with their software and not with the one that you used here.

    Backup recorded data over network?

    You need a pc with an nvr connected all time through network with enabled the real-time archiving. This way you will have a mirrored second storage backup of your video footages.
  23. Try this one http://www.scribd.com/doc/87784773/45/Schedule-Menu don't be fooled by the model name it's an oem dahua
  24. Hi Did you do figure out if this dvr has mirroring capabilities ? I read from the manual that you must specify a hard disk as redundant, You say that you grouped all 4 hard drives in 1 group so by the manual you can not enable the redundant capability. In order to do that you have to break one of your hard drives from the group and set it from disk management as redundant. After that the manual says you have to go to the schedule menu and enable the redundancy in the cameras that you want. If you manage to do that, please tell me if this works ok and with out glitches
