I hope this configuration is more than enough for a plant/factory. Tell me where is the problem, or if everything is OK then why video quality is poor over internet. Will appreciate your quick response. Regards: sant Share this post Link to post Share on other sites
tti-plus 0 Posted October 11, 2010 How many cameras and what kind of internet are they using Share this post Link to post Share on other sites
sant12345 0 Posted October 14, 2010 16 cameras with internet speed 3 Mbps Share this post Link to post Share on other sites
Soundy 1 Posted October 17, 2010 The specs listed don't really mean much - they sound like any number of no-name offshore products out there that may or may not actually be of any quality. Do any of these things have actual make/model numbers? Share this post Link to post Share on other sites
Kablooie 0 Posted October 18, 2010 They are not happy with the quality of video over internet. - Is that when viewing live or recorded video? - What record settings are being used? CID, HD1, D1, etc. - How many cameras are being viewed simultaneously? - Is remote viewing being utilized at more than one computer at the same time? - You stated "internet speed 3 Mbps". Is that upload or download? What are the bandwidth specifications from both sites (upload and download)? - Is there a setting on the DVR that controls Internet upload speed? - Can you post a sample video?

What are the bandwidth specifications from both sites (upload and download)? Also, is that the ISP's CLAIMED speed, or is that ACTUAL speed? If you're on DSL, you do start to lose bandwidth beyond a certain distance from the head-end. Use a site like www.speedtest.net to check your ACTUALY upload and download speeds.

tesc_cctvpro 0 Posted October 20, 2010 It is not often that you are going to get the same quality of video over a network as at the local machine. If the dvr you are using doesn't have dual streaming facilty - a seperate stream for network, then even more so problematic. If there is a seperate stream facility for network then you need to reduce the bit rates and picture resolution settings. Network transmission is always a trade off between quality, speed and bandwidth capacity. Unfortunately too many vendors lead customers to believe you can just plug 16 cameras into a network and all is well - we have customers ask us to remove the cctv system from their corporate networks due to the effect the load has. H.264 compression is fine, but it comes with a premium on the client PC side as H.264 will require more processing power than the other network unfriendly codecs. Image quality can differ from monitor to monitor as well. Some monitors are just awful. usually we reccomend running CCTv video on a seperate parrallel network. Of course you just may have a poor DVR. Many people buy cheap and find that the product was well valued - low value that is Share this post Link to post Share on other sites
