w1zard Posted July 31, 2008 Posted July 31, 2008 Doing an install in a domestic house, cable runs max 30 meters. Looking to install covert PIR camera with audio Is RG59 with seperate cable for audio the best solution, the cat 5 route seems a bit messy with the balun especially trying to hide it behind the PIR Is there a difference in quality of the transmission Is it an issue if the DVR is going to be connected to a NACOSS approved alarm Are these covert camera's with PIR sufficient for the approved alarm Interested to know your views
james.wilson Posted July 31, 2008 Posted July 31, 2008 for the lengths your ona bout coax will be fine. But i dont understand what you mean about the alarm? You cant connect anything to your approved alarm without someone signing it of as ok. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

arfur mo Posted July 31, 2008 Posted July 31, 2008 Screened beldon 4 pair for telemntry and rg59 for video every time for me ! yes, but he needs to hide the cables in a domestic regs alan If you think education is difficult, try being stupid!!!!
SUBS Posted July 31, 2008 Posted July 31, 2008 yes, but he needs to hide the cables in a domesticregs alan If its a really short run, less than about 10 yards, I'd be happy to use intruder cable. This will horrify a lot of people, but I bet no one could actually see any difference in quality. Its a lot easier to hide it, PIR cameras usually have screw conections anyway, and if your replacing an existing PIR and theres 8 core already in place it sho do save a lot of time. Just join co-ax to it in the alarm panel, and terminate with a BNC. Home home on the range..etc.

SUBS Posted July 31, 2008 Posted July 31, 2008 screened alarm cable - cameras love it No, Ordinary alarm cable, screened cable has a much higher capacitance, be ok for very short runs, but you will lose some of the higher frequencies over any distance. But TBH, with most covert Cameras, it wont matter and very few people would be able to tell the difference. Anyway, can you get screened 8 core ? I used to use screened 6 core for Prox readers on some systems, but Mayflex dont, or at least didnt stock screened 8 Core.

I used to use screened 6 core for Prox readers on some systems, but Mayflex dont, or at least didnt stock screened 8 Core. you only need a six core anyway, just pair the cores up, dont even bother with coax at the recorder end - SYSTEM Q sell some screw terminal BNC connectors, theres an art to getting the 12v pair back out of the rubber boot but it looks quite trick. On a domestic i`ve never used anything else
CompostCORNER Posted August 1, 2008 Posted August 1, 2008 Composite cable is pretty good for domestics. I think it was mentioned earlier in the thread. About the same size as an 8 core alarm cable, but with a mini screened coax and 2 pair in the outer. Only thing with this cable is the price. Alternatively, there is a mini-coax cable (RG179) available that is as thin as an 6 core alarm cable, comes in white, and mini-crimps that fit it correctly. One of these and a 6 core alarm cable for power should help keep things neat. RG179:- http://cableexport.en.ecplaza.net/12.asp Although the minimum order is 32KM lol, you can find it by the 100mtr reel if you look around.
