Sigis 0 Posted March 11, 2013 Hello. I`m looking for DAHUA 3200C series bullet camera. Looked on some via online connection, and other on YouTube. But till now can understand why video quality is so different? Different compress ratio on 1080P or what? Look at these: http://www.youtube.com/watch?v=ok-mEqZuPMk Looks really sharp with great details Now this one: http://www.youtube.com/watch?v=RFtTz-QFK7w Details looks much more blur. No such sharpness. Chinese from Alibaba give to me connection to their cam 3MP bullet. I take snapshot. Picture looks terrible. I have attached corp picture. why video quality looks so different? Which one is real? Share this post Link to post Share on other sites
blakem 0 Posted March 12, 2013 Im guessing the connection you were given was compressed, but it looks more to me like they just need to adjust the focus on the camera. Those youtube videos are impressive and got me looking a little closer at these Dahuas. In the first video the lighting is fairly flat in the shade so the exposure is very nice, in the second video I believe a different lens with a longer focal length is used. The lens in the second video may not be as good a quality. If you look at some of the specular highlights in the video you will seed a blue shift or halo which is chromatic aberration and an indication of low quality optics. That is probably what is contributing to the second videos lack of sharpness in places. To spite this however you can almost make out license plates at a harsh angle while they are traveling around 20mph. I suppose in the end you are taking some gamble buying one of these because they vary from seller to seller. Maybe if you found a reliable source that others have purchased from you will know what you are getting. Share this post Link to post Share on other sites
