Ok guys, still a bit confused. I haven't had the chance to try it out yet but I will definitely give it a shot tomorrow. Here's what I'm going to do if I understand correctly. I have to double up the power wires. So what I'm thinking is using solid green and solid brown for the positive terminal, then use striped green and striped brown for the negative terminal. Please let me know if I am correct in this or what configuration I have to do just to double up the cables for power. Thanks again guys! Oh and should I double up on the video as well? The picture does come out clear when it is up...

Not too sure on the make and model, but its model number is: G4-HRS-480. I am pretty sure it is a bullet style camera. It might be this from looking on the ispyvision website: 1/3" Sony Super HAD Day/Night CCD. And I am using 1 pair for power, did not know that I could use 2 pairs for power as well. Let me know if I should use 2 pairs or not. Thanks again!

The camera draws DC12V according to the spec sheet. I am using 2 twisted pairs, one pair for the video and one pair for the power. There are about 6 90 degree turns that I have made running this cable. I am not sure if that could be the cause of it. I will probably try to re-splice the cables to see if that makes it any better. If you have any more suggestions please let me know. Thanks a lot Collin!!!

OK I have a basic question. Basically at work I have set up 16 cameras with a Geo GV-1480 system. All the cameras are working fine...except for one. The issue with this camera is that it is constantly losing video. I have switched the cables from one camera port to another and after about 10-15 minutes all I get displayed is Video Lost. I am certain the cable is not the issue (the 8 port one to the computer). We are using a CAT-5 cable and the run is approx. 575 feet. I have replaced the baluns on both ends repeatedly and the results are the same. I'm not sure on the brand of the baluns but they both say GEN IV Technology. Also, we know that there is good voltage across the run. At the camera end, we are getting 12V DC power. So with all these factors does anyone have any ideas/recommendations/am I in the right forum? Thanks in advance for the responses. Jerome

Well, I just went out to the camera and thought I could adjust the lens manually, but there seems to be a protective plate on top of it. I got a picture of it but don't know how to post it here, lol I'm a noob at these things. I believe it's a Sony camera, with the model no: G4-HRS-480

thanks for the repsonse Ken! The specs for the camera in question states that the lens is a 3.5~8 Manual Lens. So I am guessing this means the one that I can just go adjust manually right? Please correct me if I am wrong. Also I will go get a picture of the lens and post it.

Ok, just a little background first. I'm a manufacturing engineer and a month ago my boss told me to go ahead and hook up the security cameras all around the plant, with me having no knowledge on it. After the first 4 cameras, the rest were a breeze excep tthat the video cable runs (rg-59 and CAT-5) were quite long and especially difficult with the plant running. Basically now, a month later I have finally finished running cables, mounting cameras and hooking them all up to the DVR system. Now out of the 16 cameras that are up, 6 are giving me some weird video issues. I am not too sure on the specs but I do know we are using a GV-1480 card and the software that comes with it, I am not too sure on. 1) When I set the system to record after i leave on a scheduled recording and on motion detect, a lot of video on these 6 cameras is recorded. The system records a slight "glitch" in the video and records for 3 seconds. This occurs on and off throughout the night but is consistent with a couple of cameras. I have redone all the ends on both sides of the cameras (rg-59 and CAT-5) and the problem still persists. Any ideas on this? 2) With the last camera that was set up, the picture was completely fuzzy. The video cleared up on things that were about 6-10 inches from the lens, but anything further the image gets completely blurred. Is there some sort of auto-focus function I am missing in the software? Or is it just possibly a bad camera? (BTW I switched cameras and found out it wasn't the cables) 3) For the CAT-5 cables the baluns that came with the system are GEN IV passive baluns. Is there a specific way I need to hook these up? Does it matter which one goes on which end? There are 2 baluns that came in the package, one with a 10 inch extension cable and another without. 4) Another simple question about this software, if I want to record all weekend while no one is supposed to be at the plant, when scheduling can I just set it from 00:00AM to 00:00AM? Like I said, not too knowledgable on this type of thing. Thanks for any help and I will try to answer any questions that I am sure you all will have for me. Jerome

Well, I just tested out a camera using the CAT-5 cable right where the DVR is at. It worked perfectly! That was going to be my next question there, our maximum length that we would lay out these cables would be 500 feet. I am not too sure about voltages across cables, but to your knowledge do you think that standard a CAT-5 cable would lose voltage over that length? Thanks again for your help!

Thanks for the answers Ken! One thing that I really do want to understand, when connecting with the CAT-5 as is, does it matter which pair goes to the camera or power? Or just as long as they are the same pair on both ends?

I am very new to this type of work. A little background. I'm a manufacturing engineer at a cabinet manufacturing plant. About a month ago my boss tells me that I'm on the security camera project (with absolutely no knowledge on it) and I need to get these cameras up and running. I am not completely sure on the specs of the computer but I know we are running GV-1480 Series on a PC. Since I have been on this project, we have set up 5 cameras using the siamese cables from ispyvision.com. We have 11 more cameras to set up, however we have run into a slight issue. As we are getting to the last few cameras, we are definitley going to run out of the siamese cables. From talking to my boss, he said something about hooking it up with a CAT-5 cable. Today, I just found out that our whole package came with about 6 Twisted Pair Video Transceivers for CCTV. So my question is would it be more cost effective to get more siamese cables or start using some of our CAT-5 cable that we already have (however the CAT-5 would still need to be run). From doing a bunch of reading on the internet I also have a few questions about the balun/CAT-5 setup (I haven't found any answers to some of these specific questions online). Now to the questions... 1) As stated earlier what would be more cost effective, CAT-5 or another 1000 or 2000 feet of siamese wiring? 2) If using CAT-5 cable, would I need to have a special power adapter to get power to our cameras? What is the average cost? 3) Would I be able to just run a single CAT-5 cable to the camera, and then to our pc DVR system, then just hook up the baluns to both ends (for the video) and then just use the other left over pairs to run power? Any help would be greatly appreciated as I am completely confused and lost. Thanks in advance for any help!!!
