Ok guys...here's what's going on.. Moved the CAT5 line away from the high power conduit .. Still with the distortion. Tried to install video isolators in the line...This worked a little bit but I'm still having the issues. I was not able to pick up the active baluns. I'm probably going to order some today to see if they will fix the problem but I'm still having this weird issues.. If I plug 3 of the cameras into the video balun, the video is ok to an extent..whenever I plug the 4th camera in, the video goes to crap on two of the other cameras. I check to see if the line was crossed anywhere and also checked the connections and everything is fine. The camera in question shows up fine whenever I plug it into my field test monitor... I am out of ideas and I don't know what the Issue could be....Anyone ?

Soundy, you are on it my friend ! I had a guy out working with me on this project and from what I could tell, he strapped the CAT5 directly to the conduit. I would say it runs for about 30 to 40ft before it branches off.

Yeah but running cat5 with passive baluns is not helping either. At that distance I would not hesitate to go active to passive. That was my second thought was to switch over to active..but you wouldn't use active at both ends? I figured that the passive baluns would at least cover 350'ft . So on Tuesday, I plan on switching the CAT5 over from running along the 480v conduit and then switch the baluns if that doesn't work. .....and HOPEFULLY it isn't the cameras EDIT: Pics Length of warehouse were CAT5 was run The silver conduit to the left of the fan is where my tech ran some of the wire against. Charging station on other side of the warehouse View from one of the cameras (pic taken on my phone, not from camera). Power box is located in the corner by my black truck Outside power box. Power box is bottom left light colored box...Video is small box on ground ( it is raised off the ground) DVR location - Maybe interference from Switches or Equipment ?

Think so? When I look at the video feed at the cameras, I don't see the distortion. The only other thing that comes to mind is that when I was at the site yesterday, I noticed that one of my techs ran the CAT5 line right next to a 480v conduit.... The conduit runs to a 480v sub panel that they use for their forklift chargers..idk may have something there. I forgot who asked or suggested, but there is no grounding for the DVR plug and the cameras are mounted to fiberglass poles so I don't believe that there would be any interference there...

My mistake... 8 OUTPUT 24VAC 4.2AMP

If I were to run a single siamese cable to each individual camera, my max run would have been close to 700ft total. It was my original intention to run that length but I did not want to have problems with the video signal later on. The setup is not complicated and I am sure that a tech with a little common sense would be able to figure out the wiring. If not, there are labels on all of the wiring that I did and that at least should make it a bit easier. This is just an outline of the site to make things easier to understand. I did not get a chance to go out to the site. They were doing upgrade and only were available for half the day. The video degrades on the DVR side and not coming in from the cameras. I did take some pictures and I will upload them here in a bit.

I will also check the voltage on the camers when I go back out today. I have some toshibas that I can throw up to see how they look. Im sorry you had problems with the 640 but I hope that is not the case with these cameras ! I already threw away the boxes.....don't ask why I just did not think I would need them. lol I think the heat was just getting to me yesterday. I'm getting read to head out there in a little bit to test the connections and take pictures of the distortion. I will bring back my findings.

Im going to try to get back out to the site today to see if I can get some pictures. I would have taken them yesterday, but I was a little to tired. I will post them up today if I can. The layout you have is a little wrong. I try to explain it better....sorry. From the camera, the video is connected using siamese cable down the line to the power supply and video balun (max distance from camera to power supply and balun equipment about 275' - 300'). The power supply and video balun are in seperate units. Video is being transmitted back inside the warehouse and to the office using CAT5. Video balun are at both ends of the CAT5 cable. I would say the distance on the CAT5 is around 300' - 400' feet also. I am using two CAT5 cables to send the signal back from the cameras. One of the CAT5 cables is sending the signal back for four of the cameras, and the second CAT5 is being used to send the video back for one of the cameras. All cameras are showing the distortion. Video baluns at both ends.

1. I have a test monitor that I was checking the cameras with but when I plug into the video feed, the cameras look fine. Granted my test screen isn't an LCD but it does the job. 2. Same thing. When I plug in directly in the back of the camera, I don't see any of the distortion. I had one of my techs sit inside at the DVR and let me know if he sees anything. He told me he still did. 3. Im going to try to get back out there today with a DC power supply to see if that has anything to do with it. I was thinking that it was the power supply because I have not had these problems and this was the first time that I used the AC power supply. 4. I took my test monitor over to where the video feed was, but once again my test display does not show me anything that clear. I may have to find another screen to use to be able to see the distortion and find the problem. My siamese cable is from sewell direct. Ive ordered from them in the past and that make some pretty good products.

Hello everyone, My name is Josh and the company that I currently run is MasterVision Technologies out of Tampa, FL. The company is pretty small for now. I don't have to many highly trained techs ( I perform most of the technical work myself and I usually have a few helpers wither me), but my vision is to have a successful client base within the next few years. I was trained mostly in the IT field but I have been doing service work / break / fix on CCTV equipment for the past 3 - 4 years. I love the work and I can remember when I was younger and I used to tear apart everything in order to see how it worked. I had a quick question to ask the forum, but I decided to introduce myself here first. I don't really have too many other people to call and bounce ideas off so it is nice to see a community of all like minded people. I guess that is it for now. I hope that I will be able to contribute as much information as I recieve from this forum. Thanks, Josh MasterVision Tech
