can anyone recommend a good passive/active balun that is good for 250-350 metres...

ive tried system q passive ones and to say the least , the picture at the dvr end you definately know is a cat5 run and not coax- it seems with me on balun runs you always get that slightly washed out picture look ,,,with a bit of interefernce added .

i like nvt baluns but there a bit pricey ,,, im after active baluns that amplifier , remove any interfernce and generally give a picture indinguishable from a coax run..

perhaps the interferenceim getting at the dvr end , is because the cams locally are being power by switched mode p/s and not standard linear boxed 12v ones... i dont know..

any recommendations anyone ?

all are installs are on building sites , all 12v cameras and all anywhere between 50-350 metres - 400 metres max ..

any balun recommadations that work would be very appreicated....glen

I use dynamic but have had them from various places, most seem to be from the same manufacture, orange and silver label.

Ive had well over 500m and the picture is crystal clear.

Short stuff we use genie. Longer range nvt.

Genie stuff we use seems ok, no problems off memory

off topic (ish)

would be good to have impartial comparision for lots of kit, bit like top gear etc.

(nope, not doing a clarkson/may bit ox, so leave it , then again.. & how come they dont get sued for being nasty/honest etc?))

I will be doing that Mr p. But some things are hard to compare.

indeed, like G3 pir detectors not affected by smoke cloak (still working on youtube etc..)

Have you ran the power down the same cable.

Like James we use Genie for short runs and always NVT for the longer ones.
