dj29152 0 Posted June 26, 2006 Dear Forum members, i ahve been reading about CCTV and have been studying it for a while. I have also installed a CCTV system (geovision) with my cousin. The thing is that the picture is clear its just that, you know when your trying to recieve a channel with one of those radio shack antennas... its is clear but liek u can see loops of red stuff, red looping things come.. so i wanted to see what other people have and compare to the one that my cousin and i have installed. i will aslo take screen shots of the setup and post it so forum members can see what i am talking about clearly. but in the mean time does anybody have like a webcam setup up (geovision) so you can view online. i just want to compare the video .. im not trying to be nosy or anythign thanks a lot Share this post Link to post Share on other sites
kido 0 Posted June 27, 2006 Look, you sound a bit unexperient on the subject. I apologise, dont want to be rude. you are being nosy, what do you want to achieve? a good signal. 1- verify if the radio shak stuf you have are paired eachother meaning that if they are meant to work as a pair. 2- environment, most times users opt to spot an area to spy then recieving the signal is a second thing. then you find out that you cannot recieve the good signal necessary and you blame the reciever not necessary the case. 3- Use proper tools to test your signal, what is it ? 2.4ghz or 2.1ghz? 4 -if you dont have those tools, then move to a diferent environment, Clear openspace room, flat outside field, not to close either. wireless systems dont like to be to close 5- if the kit doesnt have any manual frequency adjustments then i think you are screwed. in that case retun the kit and never think that you buy good stuf cheep. I could carry on but in your shoes, time is money, even if your not doing it for the money, but hein! thing theres other things you can be doing... Best of luck Share this post Link to post Share on other sites
Thomas 0 Posted June 27, 2006 It's not nosy. Some dealers keep demo systems online for prospective customers to view. But I think there may be some confusion. 1. Are you using wireless cameras? 2. What type of cameras are they? Share this post Link to post Share on other sites
rory 0 Posted June 27, 2006 GeoVision has their own Demo .. Server name - GeoVision User and Password - leave blank IP Address - webcam.geovision.com.tw Also view the recorded Videos on my home page. You're problems are more than likely related to the Rat Shack cameras. Always test the cameras directly on a CCTV Monitor (or even a TV) first before putting them in the DVR.

dj29152 0 Posted June 28, 2006 im sorry if you guys havent read my whole post but no where i have mentioned wireless cameras. all of the cameras i used are hardwired back to the PC DVR system. and for the red lines...um they are more like red oval loops when viewing it im gonna post some screen shots soon so you guys can see give me a couple of days Share this post Link to post Share on other sites
libertysurveillance 0 Posted June 29, 2006 The thing is that the picture is clear its just that, you know when your trying to recieve a channel with one of those radio shack antennas... its is clear but liek u can see loops of red stuff, red looping things come.. When you said that, people thought you bought cameras from radioshack and you mentioned antenna so they thought they were wireless. I think he's using an analogy, he's comparing his geo setup to an old rabbit ears tv setup. Never seen red lines, loops can be a few things, some cameras i've come across dont work well with geo im not sure why, ground bnc maybe? But they loop on the screen, never to bad, but just enough to notice. If you just save a quick video and post it some where, we can take a quick gander.

Thomas 0 Posted June 29, 2006 Note that he didn't say he used wireless, just that it looked like it. What interferance patterns look like depend more on what is causing it rather then the method of transmission. Second point. Keep it nice. If you can't post without forming a lather then don't post. Note that I have deleted one post from this thread already. Share this post Link to post Share on other sites

rory 0 Posted June 30, 2006 Did you plug any of the cameras directly into a CCTV Monitor or TV to check the video outside of the DVR? What type of cable is used and how long are the lengths ..? What kind of power suppies are used and what are the total Amps? Rory Share this post Link to post Share on other sites

vf702 0 Posted June 30, 2006 I'm a bit confused looking at the Reg. 9 Output DC Multiple Output Power Supply you linked to. I see that they use the same image for all of their regulated power supplies, with poor descriptions on the pages. It may help if you link the specific cameras you purchased or scan and post the spec sheets that came with the cameras and power supply. Just to clarify, are the red ovals on all of the cameras or just some of them? If just some of them, are they on just one brand of camera? Share this post Link to post Share on other sites
dj29152 0 Posted July 1, 2006 alright pictures are in... to me this is bad quality Camera: NVCC-HD http://www.nuvico.com/product_detail.asp?strCategoryCD=CC001&strModel=&prod_cd=NP0024&Page=1 Camera: http://www.cctvspecialty.com/coinhirebuca.html Camera: NVCC-W28IR12N http://www.nuvico.com/product_detail.asp?strCategoryCD=CC001&strModel=OUTDOOR%20BULLET%20IR%20CAMERAS&prod_cd=NP0039&Page=1 Camera: http://www.cctvspecialty.com/1webucawsose.html Camera: http://www.cctvspecialty.com/codoinwaca48.html btw i am definately NOT buying from www.cctvspecialty.com again. ok but see what i mean.... like in the pic u cant see the fuzzyneed but even though look how poor the quality is.. jagedy edges ...just poor.. is it that we are using wrong cabling? different way of crimping the BNC? making a proper BNC connection? to my best knowledge i know that if there is a problem it would have to be with the cabling/connectors what do you guys think?
