jakub.j 0 Posted November 2, 2015 I have problem with image quality. Camera is D-Max DCC-521FH TDN 1/3'' Sony Super HAD CCD. Recorder is Samsung SRD 1670DC. With short 1m cable connecting camera and monitor image looks good. When connected through instrastructure of 100m RG6 there is color cast, unexpected dots. Should I assume low quality cable or camera? Share this post Link to post Share on other sites
tomcctv 190 Posted November 2, 2015 Hi. You need to run Rg59 and not 6 for your camera Share this post Link to post Share on other sites
jakub.j 0 Posted November 2, 2015 The actual description for the cable is: YWDXpek 75 1.0 / 4.8 Resistance of inner conductor: 23.7 Ohm / km The outer conductor resistance: 17.5 Ohm / km Capacitance: 57 nF / km, Impedance: 75 ± 3 Ohm, The inner conductor: copper single wire Insulation: foamed PE Outer conductor: braid of tinned copper wires and tape AL / PET / AL Braid coverage factor: 40% Share this post Link to post Share on other sites
the toss 0 Posted November 7, 2015 I'm guessing that those two shots of the boom gates are taken through a glass window - if so then 1st mistake. 2nd mistake (as Tom points out) is to be using RG6. I'll start up the broken record ---- RG6 is designed for high frequency RF signal transportation (digital TV etc) and the shielding is optimised for frequencies above 50Mhz. Little consideration is given to shielding of interference below 50Mhz as it is well outside the TV bands but unfortunately falls partly inside the CCTV baseband range of 5.5Mhz. RG6 can and sometimes does work ok but you wont know til you try it and if it doesnt work your only option is to pull it out and replace it. Best to use the right cable in the first place. Braid coverage 40% dear oh dear Share this post Link to post Share on other sites
