    So for video only this looks about right? http://www.mcmelectronics.com/produc...=prodCrossSell

    Seems odd they only use one wire of the cat5 cable.

    I think the first set was cheaper. You have to buy 2 of them, The other was a pair.

    Video is nothing more than an AC Signal with Various Frequencies,
    So You only need 2 wires (1 twisted pair). Leaves you more conductors for other things.

    You can power LEDs. IR lighting works best with B&W cameras.

    So now I don't know what I really have. Here is the product and I dont see any place for a cat5 cable or contacts.

    Nightmare.

    No description given other than it is for a cat 5 bezel (maybe a wall plate). It is possible that this connector has to be crimped to a Cat 5 cable (bulk cable) with an IDC tool

    Anyone know what passive keystone type over cat5 bezel means?

    There are two 1/6" holes on the rear, and no instructions of course. Perhaps those top tabs are to engage the cable, but everyone says they only use one wire of the cat 5 cable.....

    You use 1 twisted pair , 2 wires in the Cat5 wire and connect to the 2 connections.

    That gives you 3 more pairs for three more Cameras or other things.

    Just make sure that you connect the same Pair of wires on the other end of the wire.

    Pairs are 1 wire with a solid color then 1 wire with a white strip, and will be twisted together. 2 (Two) Wires.

    thanks. But i screwed up with these, as now I have to screw with cutting off the ends and stripping that little stuff.

    Now the dog cut a 200' cat5 cable. Can I splice these in the primitive method, cut strip and wind?

    I'll try again: can one splice cat5 with strip and wind, or must one use crimps and connectors?

    If you do splice, You need the keep the TP Twist as tight at possible.

    And you do need a RJ45 crimper to crimp the connectors properly.

    CAT5 cables can be joined together easlily if they have the end (RJ45 Plugs) on them, with an RJ45 coupler.

    If the ends are plain wire ends, I dunno, but googling it comes up with:

    Nice BobLŪ.

    Just make sure that you put the heat shrink on, before making the splice.

    And if you do go the connector method, Don't use Crossovers for the RJ45 F-F adapter, Use Straight Thru adapters.

    If done correct the splice should be better. Just try to keep the same twist.

    Thanks. splice and solder would likely exceed the cost of 200' of cat5 which is down to about 10 bucks and less with connectors. Maybe a muzzle for the dog would be cheaper yet.

    Default balun with RCA

    The MuxLab 500021 and 500031 are composite video baluns with RCA on one end and Cat5 on the other.
