We have a CCTV system with 128 analog cameras. We are currently using two PCs with hardware cards and considering upgrading to a DVR system because of the unstability of our current system. Where I reside, not many companies that are mentioned here available, but Samsung and Panasonic are widely used. How can you compare them to each other? In terms of stability, user interface and performance, which brand would you recommend? And what aspects do I need to be careful about when buying a DVR? Thank you

Hi, I've four 16-channel DUNLOP DS40xXHC cards installed on my PC. The software I'm using is NVR Server & Client which is very slow and unstable. I was wondering if this is due the cards or the software. Does anyone have experience with these cards?

Yes, there are about 128 cameras. And just make sure, I've checked my card's name under device manager and it is listed as "DUNLOP DS40xXHC". Now I recall it being Dunlop DS 4016 HSI. The compnay who installed my system told me that it is same as Hikvision card (even the part numbers match). I don't know if it's true or if Dunlop is a sub-company of Hikvision. But yes, I agree, I should first try updating the software as my main problem is the software.

This is the card I'm using: http://www.hikvision.com/en/Products_show.asp?id=17 And the software is called NVR Server/Client v. 5.38 Which DVR would you recommend? Is Samsung reliable? And what about using a different software such Avermedia or Geovision? Will thtey work with my cards?

Yes, they are analog and terminated with BNC connections.

Hi, I've been using a CCTV system for the past few years and I cannot hate my current system enough. Unfortunately here where I live (Turkey), the system I'll explain below is widely used and the market is full of useless and overpriced hardware. My current system is a PC-based solution. I have two PCs, each with four 16-channel hardware cards made by a company called Hikvision. And the cameras are either Dunlop, Elegance or some other unknown brands. And 4+1 copper wires run from cameras to the PCs. My main problem are the server and client software. They are full of bugs, very unstable and run only on Windows XP. The company who installed my system acknowledges the problems, but they don't have any solution. Upon not seeing any of the brands I use mentioned here, I feeel like my system long became obsolete. Is that true? I thought the software solution always came with IP cameras; and the rest with 4 copper wires are used with DVRs. However, my system is a mixture of both. I do not want to change my cameras and cables; they are fine. But how can I upgrade my recorder? Would you recommend a DVR? Or maybe better software such as Avermedia, Geovision, Exacq etc (if they are compatible with my cameras). I was told that each hardware card is compatible with its manufacturer's software; if that's true, than I would have to replace my cards as well. And last, but not least, I've watched a few review videos of Samsung DVRs and they seemed quite effective and stable. What can be said about them? Are they compatible with any cameras? Many thanks
