Hello, I have a business that requires permanent video surveillance (24h/day, 7/day/week) and i need a few employees to watch 3 or 4 monitors witch display all the images from the DVRs. To do this i need to make a dispatch to gather all the images provided by the remote DVRs to one room using internet. Now i watch the cameras myself using my mobile phone or my desktop (IE), but i can't stay 24h/day watching monitors. The reason i made this post is because in all my remote locations i have poor internet connections (GPRS/3G), with limited bandwidth and i can't use it 24h/day to watch the images. So i need a solution for this problem like this: - i need a software to be installed on a server computer to receive images from all my locations. This server software must be compatible with all my DVR (Hikvision) and must be configurable to take one image form each camera at an interval time wich i set (like 1,2,..10 or 30 seconds) - the client software installed on multiple PC must analyse the images taken from the server and inform my dispatchers if there are some changes between each frame Do you know any software i can use to handle this problem? Thank you!

Color image became b&w with blauns on my PC DVR. why?
vmb replied to vmb's topic in Video Transmission/Control Devices
First i test one camera with passive blauns and 1 meter cable. The image is black & white. I test the same camera on 30 meters coaxial cable and i sow a perfect color image. All the camera are power at 220V with source cables between 20-30 meters. I also ask my supplyer and he answer me he heard about the problem and the main reason is the FTP cat5 cable. He told me i have to use a full copper UTP Cat5 cable and not a copper alloy cable. Ok. But why is working with non PC based DVR? I tryed both NTCS and PAL. - this was the first thing i did. -

First thank you for your time. I try to put 75ohm resistor on the twisted pair before and after the blaun and i also try to stik it to the board in the computer. In all cases i have the same result - not working fine (b&w). I also check my DVR for NTSC and PAL. Now is PAL but i try NTSC with no result. I don't understand what is wrong with the PC DVR? With non PC DVR image is perfect and color. My camera is AVC565 -

I tried with 75Ohm resistance. The image is darker but is still black and white and not very clear. I don't know that elese to do. -

Hello. I have a very strange problem to solve. I mount a video system of 10 color cameras(350 TV Lines; 220 V) located at distance between 45 feet and 600 feet from DVR. I used passive blauns(NVPT-111VTS ) and Cat5 FTP Cable for cameras in range between 45 and 150 feet and active blauns(NVPT-A111VT) between 150 - 600 feet. To test video cameras and cables i used a analogic monitor. All of them provide a perfect color image on the monitor during the instalation process. After that, i brought the DVR (PC BASED - 2 PCI Card x 8 video input at 200fps/card - 25fps/camera) and i was very surprised when i sow the image black and white and not stable FOR ALL OF THE CAMERAS(including the near one). DVR was working fine with coax cable between 45-150 feet without blauns.(it was tested before in other site) After a while of trying and testing , i brought a non PC DVR (Stand alone 4 input) and i tried 4 of my far distance cameras and the image was perfect just like on the monitor. Somebody told me on the phone to put a 75 Ohm resistance between + and - on the wire at DVR side. What do you thing? cand you help me please? sorry for my english! thank you for your time.
