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?

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.

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 !!

You can try this http://184.154.51.29/FTP/Luvicom/Luvicom_12.12.0/

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.

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.

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.

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.

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.

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.

maybe this is what you need http://www.ebay.com/bhp/hdmi-over-cat5

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.

I do not think so. Btw can you tell what version of dvr site are you using ?

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
