HD CVI installations

[Totalsecureguam 0]

I am getting into this new format for security systems and am wondering about the cable type that would work.

They call for rg59 , which is no problem other than the size of the wire. If I am to install a 8 camera system , to run that many Siamese cables thru the wall the hole would have to be huge.

I have found some mini coax that may do the job for short runs. Although the cost is more expensive, the resulting installation would be better.

I have also heard of people using Cat5e and baluns with some success.

Short runs , I am thinking no more than 120 feet.

 

anybody have experience with this?? very curious, I don't want to stock all sorts of cables when I don't need them.

 

thanks

Nice video on cable comparison

Looks like some color loss with cat 5 or 6 and some ghosting.

Should I be worried ?

these homes are small 40' x 60' at most

I need to make an order for the r59u soon for a project if so. If not solid core cat5e should do fine I think.

not sure about power consumption by hdcvi cameras

Short or long runs, I think quality rg59 is the best way to go. I think 12v power supplies would be fine.

Some advice on the style and brand of coax cable ends, Twist on, compression or crimp style and what to stay away from. ( I have ordered crap Baluns and had to swap all out before ) so I want to get a decent quality piece.

Thanks

RG59 will obviously have the better quality but Cat5e is good as well just don't use cheap baluns.

 

For coax ends use compression/push or crimp never twist.

All types of BNC connectors work just fine as long as there's nothing wrong with the connector itself. If you have a particular connector that works for you already, just stick with it.

 

Baluns are more hit or miss unless you already have a reliable supplier. I would personally avoid using network cable (Cat5e or Cat6) altogether; you might find yourself in a situation where you're swapping it out almost immediately.

 

Solid copper RG59/U (20AWG) works just fine with no degradation whatsoever up to 1500 feet for sure. Dahua actually recommends something even higher quality similar to RG6, but I don't think it's necessary.

Why then does qsee package the same garbage pre-made cables with their sets? That's just wrong.

that's one of the many reasons why they are less expensive

i have only installed a handful of systems but i have already come across several

defective pre-made cables that came with the (all-in-one-box) type systems .

I think I would eliminate all possible headaches and go to a local supply house ,

get a bulk spool of solid core rg59 Siamese cable , a nice new compression tool ,

and some bnc compression connectors that the supply house sells to the installers .

do it once , do it right !

I can't speak for the quality of their pre-made cables, but the only response from people that I've seen is negative when compared to a similar system using RG59 instead.

 

I think it was just part of Q-See's way of marketing it to people who wanted to avoid replacing or using more expensive cabling. The pre-made cable works but it only works to serve up an inferior image quality.
