barooga Posted February 9, 2008 Posted February 9, 2008 Because for a decent hub from PC World will cost you 50-100% more than other smaller suppliers. How do you think they subsidise all the TV adverts they have? I meant why a hub and not a crossover? Growing old is mandatory, growing up is optional
sjonley Posted February 9, 2008 Posted February 9, 2008 I meant why a hub and not a crossover? When I worked for GSL CCTV technical Support many years ago I was asked to test their Vantage 1ch dvr against their network software. Once I had set the correct ip address, subnet and gateway addresses on both, using a crossover cable would ping and even connect ok, but would not stream the images. as soon as I swapped the crossover cable for a hub and standard patch leads, video streaming started. That is one example. Other times I have worked with different dvr's and found a similar situation arising. Now through bitter experience I would always recommend a hub/switch and standard network patch leads. A point to note, how would you test two dvr's connecting to multi site software without a hub/switch?
