mudcow007 0 Posted March 27, 2015 Hello all just installed my first cctv install in my house, DVR is located in the loft an have two 1200 floureon cameras, connected to cat5e using passive baluns to the DVR. the cable runs are about 15 - 20ft max before i installed the cameras, i tested them connected to the DVR (using baluns etc) an they worked great. But since fitting them, the image is poor cable i used is JSL 100% copper utp cat5e 24awg 100% bare solid copper conductor (well thats what it says on the spool) i work in IT so have loads of it any ideas? thanks Share this post Link to post Share on other sites
Numb-nuts 1 Posted March 28, 2015 The cable is probably NOT your problem its the name Floureon, THATS your problem. Share this post Link to post Share on other sites
SyconsciousAu 0 Posted March 28, 2015 any ideas? thanks You haven't got the cable running parallel to any power or near fluorescent light fittings have you? . I've never heard of the brand Share this post Link to post Share on other sites
jeromephone 6 Posted March 29, 2015 what are you using for a power supply and are you using unused pairs on your cat 5 for power.Are the power supply and the dvr on the same power outlet Share this post Link to post Share on other sites
mudcow007 0 Posted March 29, 2015 cheers for the replies... i only one socket in the loft, so i'm having to use a 4 gang extension lead (with surge protector) power supply to the camera is a 12v 5amp switching psu thing with a 1 - 4 splitter for the different cameras i used the orange pair for the video, an brown for the power, i snipped off the unused pairs there is nothing else using mains up in the loft so hopefully nothing to interfere with it.

Securame 0 Posted March 29, 2015 Picture of those "passive baluns"? Also, you should have used the 6 extra wires for power, and not just two. Share this post Link to post Share on other sites
Numb-nuts 1 Posted March 29, 2015 A single pair for video white stripe+ve solid colour -ve Then take the remaining pairs and separate into whit stripe and solid color and use to carry the DC Power. My convention is everything that is white with a color stripe is +ve everything with a solid color is -ve. The fact that you are using a single pair for power means there is not enough power getting to the cameras this MAY be your problem but it will certainly need correcting before you can move toward a solution.

They worked ok before installing so I dont think it is a camera issue. Look at - split pair or wrong polarity on balun Share this post Link to post Share on other sites
