A newbie question:
Background info:
I have 16 SC23A (wired) cameras connected together using the "Y" technique specified on the X10 site. Several of these cameras are located further away than the ~60' of supplied cable, so I have added the Cat5e four-twisted-pair cable (also as specified by X10) to extend the distance. I assumed that I should use the standard 8P8C modular connectors as are used when the Cat5e cable is used for is normal LAN applications, so I terminated the Cat5e cables with those connectors and then used in-line modular adapter jacks to connect the cables to the respective camera cables. This all "sort of" works, but has some performance problems - hence my questions:
With the cameras all wired together this way (and with only one camera activated at any given time), the image quality is seriously degraded: It appears "foggy" and also has multiple "ghost" images (about five or six that are apparent) that are slightly offset in a cascade to the right of the primary image. This appears to be video signal "reflections", most likely caused by mis-matched impedances somewhere in the system - like one might get when using an RF coax TV cable with unbalanced connections - but I'm a little surprised to see this sort of effect at the relatively low frequency of the line-level video signal. So, my question is whether my theory of reflections caused by mis-matched impedances is valid, or if there is some other explanation for the problem?
By the way, if it IS caused by signal reflections, then what do I need to do to correct the problem? Do I need some sort of baluns? If so, what, and where? Where can I find out the impedance of the cameras' video outputs and/or the TV's video input, so that I can put in appropriate components to match those impedances?
Thanks in advance...
