mshaumi 0 Posted January 5, 2008 I bought avc 760 last week and when I try to backup, it takes a long time to finish the download. I connected my dvr and my pc through a switch router. And DU meter said the transfer rate is about 1.7 mbps (maximum). (I used AP Client software 1.0.6.6) Its confusing me since the manual said that dvr support 10/100 base T while the backup transfer very slow, not even 10 mbps. My PC LAN CARD is 100 mbps. Any body may help to explain, is that the standard transfer rate of AVC 760 or maybe there is something wrong with my DVR. Thanks in advance. Share this post Link to post Share on other sites
scorpion 0 Posted January 8, 2008 What kind of computer are you using, and what are the specs, and what operating system are you using? Have you tried connecting to the DVR with a cross over cable for comparison? Share this post Link to post Share on other sites
Kiwi 0 Posted January 8, 2008 As a reference point, on my 782 the Video Server E application indicates average network speed is about 1860 kbps when viewing live video. A 5 MB download takes 27 seconds, about 1520 kbps. I don't think there is anything wrong with your system. I can't see any reason why the network hardware speed should necessarily be the limiting bottleneck - it could be the DVR processor for example. Share this post Link to post Share on other sites

Have you tried connecting to the DVR with a cross over cable for comparison? My computer is Pentium E2160 dual core, memory 2 GB, OS XP Pro SP2, I tried with cross over cable too but still the same. As a reference point, on my 782 the Video Server E application indicates average network speed is about 1860 kbps when viewing live video. A 5 MB download takes 27 seconds, about 1520 kbps.

Thanks kiwi, according to your speed that's almost the same with my download speed. Download 1520 kbps= 1.5 mbps, live view 1860 kbps=1.86 mbps.

Anybody could ping ur AVC dvr with load " -l 2000 " ? Share this post Link to post Share on other sites
Kiwi 0 Posted January 8, 2008 Yes, I get RTO. I haven't used that parameter before, what does that tell us? Share this post Link to post Share on other sites
mshaumi 0 Posted January 9, 2008 Yes, I get RTO. I haven't used that parameter before, what does that tell us? Thx kiwi. About the parameter my ISP told me how to check the bandwith with load. And I tried to ping my router and other computer in LAN even with maximal load (65500) and I never get RTO, I think the DVR firmware just limit the bandwith for some reasons because the DVR use RTL 8201C chipset (10/100 mbps). And this make the download, control the DVR, and live view very slow. Share this post Link to post Share on other sites
