  • Security Camera Baluns handy

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    I've used these things to put security cameras around my house. Using these means I can get away with running a single cat5 cable which is a lot cheaper than a coax + two power leads.

    These also support Audio but I don't record that.

    Cons:

    They're a little bulkier than others, but these ones work well.

    The wire in the power lead could be thicker - I've had to snip and bare a couple to connect to older cameras with those cable gripper connectors, instead of power sockets.

    I'm pretty sure these add a bit of noise to the image, but they don't make it fuzzier or anything.

    OtherThoughts:

    They're actually reversible - you can use two output ends or two input ends together, if you want to hack something together.

    I've also used structured cabling to patch a camera through the house. Works well.

    Joiners or poor-quality cabling make these work worse, so use decent cat5 and terminate them well. No need for cat6.

    I have a single 5 A 12V power supply that runs 6 cameras without issue, throgh a couple of splitters.

    Bottomline:

    Flexible and convenient for cameras.

    You'll also want a stack of adapters, like BNC/RCA (both ways around, and both available on trademe)
