shravank30 0 Posted April 10, 2013 Hi We are installing 32 Analog CCTV cameras in our complex for security purposes. The cameras are all 700 TVL day and night cameras The farthest distance of the cameras from our security room where we planned to keep the DVRs and do the live display was nearly 1000 feet, which was entailing a drop in video quality We are now proposing to keep the DVRs in 2 locations and attach the nearest 16 cameras to them so that the distance between the cameras and DVR will not exceed 300 feet The distance between the DVRs and the and the security room from where the DVRs will be controlled and where the live display will be done through a PC will be 600 feet and 300 feet respectively. I shall be grateful if you could give me the specifications of the PC we should go for so that we can remotely control both the DVRs and also simultaneously see the live feed of all 32 cameras on a 40" LED TV We are going for a AVTRON 16CH Video/16Ch Audio Stand Alone DVR, H.264 Compression, D1 in Preview, 16CH D1 with 25FPS, 4CH D1 & 16CIF Playback, 2HDD up to 2TB(4TB) or 1HDD & 1 SATA DVD-RW, HDMI/3G/WIFI, DDNS, CMS Software + Mobile Viewing Support, VGA, Monitor Please also advise if we need any other equipment between the DVR and the PC to maintain the signal strength and quality for display Thanks for advising Share this post Link to post Share on other sites
dahomes555 0 Posted April 10, 2013 Connection between the DVR and PC would be an IP connection, so there really isn't anything to be concerned with there. The connections to be concerned with is between camera and DVR. That's where you have the greatest potential for quality loss. But once the DVR receives the video from the camera it converts it to a digital file and then sends it over your network to a PC, smartphone, etc. PC probably doesn't need anything super crazy. Good processor (i5 or better) with a decent video card and plenty of RAM should be fine. Share this post Link to post Share on other sites

Also will a 7850 suffice or should I go for a 7870 GPU or both are an overkill and I can use a 7770 ? Thanks for advising Share this post Link to post Share on other sites

As I am attaching 2 DVRs LAN Cable to the same PC, would I be able to take the output of both the DVRs simultaneously from 2 DVI out sockets of the same graphic card to 2 different TVs or 1 single TV, as may be required ? DVR1 & DVR2 connected to PC 1 though LAN Cable PC1 output to LCD 1 & LCD 2 (images of DVR1 & DVR 2 Respectively) Thanks for advising Share this post Link to post Share on other sites
