NOLA

I only get 39 seconds of black screen.

The system I am repairing consists of 7 Pelco DX7016-480 DVRs. The security department want to add an 8th unit so I have to research prices and what not. The DX7116-480 is about 2 grand cheaper from our supplier even though it looks like it is an updated version of what we already have. Am I missing something painfully obvious here?

I'm running lines for 10 new cameras in a parking lot being redone for them right now and the chief engineer says that RG6U with the foil and 60% aluminum braid is the best. I tried to convince him otherwise but he's sticking to his guns. I'm actually a hotel employee (not a contracter) so I guess this is what I'm going to be working with.

Good to know. From this point on I will use the correct cable. If I have to rerun the aprox 130 other camera lines in the hotel I'm gonna cry though. I think only a couple dozen of them are the copper shielded cable. Apparetnly the guy before me didn't know what he was doing either.

Sorry, I've been out of town for a couple days. The cable is RG6U. 75 ohm coaxial, 60% shield. And yes, it has a foil shield in it. It is listed in the catalog where they order from as CCTV coaxial, and is labled as communications cable on the box. I'm new to the whole CCTV thing. I did electronics in the Navy before this. I'm just working with the stuff I have been given to do the job. They keep giving me a paycheck and I'll keep working with the stuff they give me until I move. I have to say though, this has been some pretty fun, interesting stuff to learn. Just reading the stuff on the forum here has been a great help. NCPILOT....Jazz Fest is almost here. No better time to visit in my opinion. Get you some Abita, oysters, and some crawfish bread while you are there and you'll be bound to run into me

Just in case you guys are interested, I finally figured out the problem. It actually doesn't have to do with the power. It turns out that on the other side of the concrete wall it is mounted on is the antenna for the security departments dispatch radio. Every time it is keyed the camera "fuzzes" out. Not sure how I'm going to fix this, but I sure am happy I now know the why.

I've never seen Idol, but I'm sick of it just from hearing everyone at work talk about it. That's pretty sad when you won't watch a show because you are sick of hearing about it.

I think I will have to do that. I plugged in to a differant outlet and it still does it, just not as frequent. The camera and lense have both been swapped out with known good ones, so I know that isn't the problem. The cable is actually RG6. Will changing it out to 59 make a differance? The run is only maybe 20 feet or so. There is an ATM below the camera, probobly about 4 feet or so below it. Could that maybe be the problem? I'm guessing it has to do with the power at this point. I'm going to have to see if the engineering department has a voltage monitor. This building is so old and messed up that there are problems everywhere. Especially since the hurricane with all the repair and renovations going on. How would I go about tweaking the DC level in case I run into this again? Thank you guys for all the tips, the response I have gotten here has been amazing.

Mmmm...red beans and rice Moondays. I put a new transformer in a differant outlet with a new power cord and the problem is still there. Doesn't seem to be as often though. DVR - good working order, have tried multiple inputs Coax Line - I just ran a new line, and is a short distance Power - Same in multiple 115v outlets with 2 differant transformers Camera - 2 seperate cameras (one brand new) both do this Lense - Swapped out lense with a differant new one of a differant size. Am I missing something here? I feel like this should be painfully obvious to me and I'm gonna feel like an idiot when I figure it out. edit: my painfully bad spelling

Yup. What gave it away, the NOLA?

I should have mentioned that earlier. The DVR is a Pelco DX7100 Series. The camera curretly installed is a Toshiba Color IK-6400A if that matters. The lense is a 4mm Pentax. I haven't had a chance to try a differant outlet yet, got stuck scanning the video from last night looking for a thief. I will post back as soon as I do.

Have tried the camera plugged in from a differant area and it works fine. Also swapped it out with a known good one just because I was running out of ideas. I checked the power before I installed in this location, the outlet I used was around 117v, and I was getting just over 24v off of the transformer. Could the power be flucuating maybe? When I get in to work today I think I'll try plugging it in a differant outlet for a while and see if it still happens. Thanks for the tips guys.

Camera is mounted to a wall on a little metal bracket. About as basic as it can be. 24V Camera, not from same source as the DVR, is in the next room over. I have tried different ports, sadly it was the same.

Kenner Police Department (right out side of New Orleans) is having a bunch of issues revolving around taser deaths right now. So what do they do? Order a bunch more of em. Gotta love this town.

Hello all. I'm new to the CCTV field, I just recently got a job at a large hotel fixing/updating their surv. system. All in all, everything has been going well. Untill today that is. I just installed a new camera for them, and am having some issues. On the monitor the picture intermintantly blacks out and turns to a fuzzy picture. It then blacks out, then comes back. It almost looks like it is getting turned off and back on. The power is good. Is using a resettable transformer right above the camera in the ceiling. The line and connectors are good. I just ran the line yesterday and did the connectors. It is only about a 30 foot run. I have tried a new camera as well as a new lense, but the problem remains. Any quick advice from people with more experiance than me? And thank you all for the wealth of information I have found on this forum so far.
