bentech 1 Posted October 30, 2014 Hi , I have a system with 16 cams analog (non varifocal) connected to a SPECO 16TH DVR. On the 16 cams , I have 3 FLIR 900 lines resolution and 13 low cost bullets cams. They are both IR cams. I set both to best quality settings (FPS , 720*480 resolution , H264 format , 120 PPS). I cannot see the difference on the image quality between the 900L and others.Only on the night vision , it's much better. What can I change to improve the quality ? Thanks.

SunnyKim 2 Posted November 1, 2014 Check your DVR's recording quality and it can really compress each video channel into D1 X 30FPS rate. If you can play back 4 Ch on HDTV monitor (1080P), you can examine their quality as they are about the same size of D1 that each camera sends to your DVR Share this post Link to post Share on other sites
