Totalsecureguam 0 Posted September 10, 2014 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 Al Kilgore Share this post Link to post Share on other sites

Totalsecureguam 0 Posted September 11, 2014 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 Share this post Link to post Share on other sites
shockwave199 0 Posted September 11, 2014 Short or long runs, I think quality rg59 is the best way to go. I think 12v power supplies would be fine. Share this post Link to post Share on other sites
Totalsecureguam 0 Posted September 11, 2014 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 Al Share this post Link to post Share on other sites
Bhawan 0 Posted September 22, 2014 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. Share this post Link to post Share on other sites

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. Share this post Link to post Share on other sites
shockwave199 0 Posted September 22, 2014 Why then does qsee package the same garbage pre-made cables with their sets? That's just wrong. Share this post Link to post Share on other sites
captainvideo 0 Posted September 23, 2014 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 !

Don Stephens 0 Posted September 23, 2014 Why then does qsee package the same garbage pre-made cables with their sets? That's just wrong. 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. Share this post Link to post Share on other sites
