mike5030 Posted August 7, 2008 Posted August 7, 2008 Hi, maybe somebody would know of a good quality MPEG-4 DVR card with low bandwidth requirements for a full D1 remote viewing at 16 channels. Existing Internet bandwidth is just around 1.5 Mbps, our current ones cannot run under the setup. I have an existing issue with this one. Suggestions will be most welcome.
james.wilson Posted August 7, 2008 Posted August 7, 2008 Id suggest D1 remote was a waste, especailly at 16 channels, if you were to attempt real time then your gonna need 400 fps @ D1. Also assuming its full screen you would need a 4 x 4 split for 16 way, and each image is 720 x 576 pixels so your gonna need as a minimum a screen with 2880 x 2304 pixels. If you go for cif then you would need 1440 x 960. James securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
mike5030 Posted August 28, 2008 Author Posted August 28, 2008 Thanks for this. How much bandwidth then for CIF?
james.wilson Posted August 28, 2008 Posted August 28, 2008 depends on your compression and codec used. if using h264 say then you could set it to a bitrate to match your bandwidth but once you take into accunt your contention you may not always achieve you maximum upstream bandwidth.
