Sounds about right,

Half the back bedroom crew out there don't have a clue, its all about a quick quid

Always Work out your cable runs based on maximum demand against cable size, volts drop resistance etc Some still find this a mystery

suck it and see is what most rogues seem to do. No planning or previous experience of issues

Sad isn't it

Cat5 is fantastic when installed properly

Sad isn't it

for the client that pays twice for 1 job (once by the rogue, and again by a pro)

Very true, again though I often feel like the crook when you spend 30 mins reeling off why the previous job was done so badly.

 

It just looks like sour grapes and that you're slagging off legitimate competition sometimes.

 

Had this the other day, although the house alarm being replaced was over 15 years old anyway, but had been installed in such

a bad way by a so-called pro we couldn't reuse one inch of the wiring even. (And in the garage, you just pulled the plug in transformer
and it all went dead. It took me a few minutes to explain why this was a bad thing...)

 

What would be considered a quality make of baluns btw?

We have used genie cctv and not had any issues.

I agree with above it seems like your trying to put their system down so you can score a job, i hate doing that.

We have used over 800 of the Adata cheapie ones for most installs, had less than a handful go duff

They work just fine for £2.00 a pair. Anything other, it's NVT all the way

the only thing genie we will use is the baluns and rack mounted PSU's..  no problems to date.

Agree totally with one pair per camera, but also make sure you have the correct white of the colour used, crossing them over will seriously degrade images., and just too easy in poor lighting on some canle to swap orange/white for brown/white.

Where possible power locally on long runs, if not possible then i use a boxed psu and move the pcb to other end of cable, feeding AC From the transformer over the power wires.

One 'trick' to try on long power runs is to fit a large capacitir at the camera to smooth voltage.
