SunnyKim 2 Posted May 13, 2014 No way you can tell it is 480 TVL or 700TVL. But you can notice its video quality with more details on the video, as 700TVL is relatively newer and likely to carry more advanced image processing techs. But always remember quality of lens absolutely rules over the video quality. As you are using a usb grabber, the max resolution can be 720X 576X 25 FPS for one channel or CIF (352X288X25 FPS) for 4 Channel. Share this post Link to post Share on other sites

joseph.chen0312 0 Posted May 15, 2014 Actually, the one is CMOS so not sure does it real 700TVL or not. For standart 700TVL correct effctive pixel is NTSC: 976*494; PAL: 976*582. Also called"WD1" as your video grapper is D1 format. Share this post Link to post Share on other sites
