squale 0 Posted February 19, 2004 What's the absolute LOWEST price somebody here can give me on a Geovision GV-250 card? including shipping to zip code: 07438 in the US Is this a good card to go with by the way for like a 3 cam setup? Share this post Link to post Share on other sites
squale 0 Posted February 21, 2004 anybody? common there has to be some Geovision distributors in here.. I need prices on the GV-250 AND the GV-600... PM me.. Share this post Link to post Share on other sites
cctv_down_under 0 Posted February 23, 2004 I dont like to upset other countries distributors so I cant give you a price, but if you feel like your being ripped off then I will let you know if you can tell me the price. P.S. Get the 600 card not the 250 as it will not support DSP card or Audio Share this post Link to post Share on other sites
squale 0 Posted February 23, 2004 Well here the cheapest I can find the 600 card for brand new... $225 http://www.turbocctv.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=TC&Category_Code=VCC What do you think? do you know if this card comes with the optional audio card as well?

squale 0 Posted February 23, 2004 do you know why I would even need the: GV-DSP Support card? what does this card do for you? Share this post Link to post Share on other sites
cctv_down_under 0 Posted February 23, 2004 DSP OVERLAY The Geovision system allows for the additional purchase of the "Real TIme Card" or GVDSP, this card allows for a full 400fps live display. The DSP card will make the Geovision viewing screen appear just like an analogue Multiplexor, without missing a single frame. When watching a television broadcast the viewable frame rate is faster than 25fps, this means that you will not see any lag or skipping of frames, in laymens terms this means that the person walking past a camera will be viewed in the same way that an anlogue CCTV monitor would view a direct input from a camera, therfore there will be no staggered affect of movement. The DSP also allows for a composite 75OHM output, this means that the signal sent form the DSP card to second monitor (spot monitor) will be a balanced 75OHM signal and will display in a Multiplexed format. The advantages of this kind of output are many, by using the Multiplexed DSP output you will not see the GUI (Graphical User Interface) of the Geovision system on the second monitor. Without the Graphical Interface the second montior will display exactly like an analogue multiplexor and will not miss a single frame, any changes made to the layout of the cameras on the Main system will be represented on the second monitor minus the GUI interface. Because the DSP card is independant of the PC video card it can generate a signal that is not digitised, this means that the signal can run for a longer distance and because the signal is a direct overlay any DVR system with this card inserted will display a resoundingly better viewable picture quality (up to 40% improvement depending on resolution of cameras used). SUMMARY The DSP overlay card is designed to allow the user to feel that they are operating an Analogue device and provides higher than normal quality images for live display without replicating password settings or GUI interface on the second monitor.

squale 0 Posted February 23, 2004 well If I got the GV-800 card I would NOT have a need for this then right cause I would be seeing 30 FPS per camera anyhow right? this is talking about 4 cameras connected at once.. Share this post Link to post Share on other sites

cctv_down_under 0 Posted February 23, 2004 Giddy up!!!! The DSP provides better picture quality and a second output without GUI and if it were a 16 cam system you would have more need than a 4 ch system which would be 25FPS ONLY at 320x240 not at 640x480.....cmon Hermin you know you want me!!!

cctv_down_under 0 Posted February 23, 2004 no they don't.. all Geo's and infact all DVr products other than hardware onboard compression chips only do fast frame rates at smaller res. Geo's specs are for only 320x240 sized resolutions Share this post Link to post Share on other sites
squale 0 Posted February 24, 2004 ah.. okay.. so ALL of the Geo cards are spec'ed at using a 320x240 window huh.. who makes chips with onboard compression? how much are they? Share this post Link to post Share on other sites
cctv_down_under 0 Posted February 24, 2004 There are now some generic MPEG4 ones but compression chips are usaully proprietry to the manufactorer, I think this is why Geo released it's own codec, I think they will go to standalone and proprietry chip Share this post Link to post Share on other sites
squale 0 Posted February 24, 2004 yeah you have a good point, it might happen.. hey they might come out with something like the BlueNet which I think is a great idea IF IT HAD MORE INPUTS. But that using a proprietary hardware compression. Share this post Link to post Share on other sites
