NVT told me that they can be daisy-chained to cover the distance. So I will have to give it a try. Plus my customer did not want to go fiber because of the cost. Solar power could not be obtained. That was the first thing I looked. It would have made it so simple. Use of LSZH cable has never been specified. I will look into that. Thank you so much.

I see. These are the NVT units I plan to use: http://www.nvt.com/content.php?type=product&key=652r&cid=root http://www.nvt.com/content.php?type=product&key=653t&cid=root They suggested that I use two sets of these to cover up to 8000 ft. Yes, I considered fiber, too. But because of higher cost involved with it we decided not to. Thank you.

I am using 2 sets of NVT active units for video. The power is not a problem? Awesome! How would you take care of the power? Thank you. Also if you have an idea on video part as well, please share.

Hi, all. I need to run 7500 ft of cable to power up a couple of active baluns and a camera inside a tunnel. According to various calculators I found online I should use 10 gauge 2 conductor cable with about 32V power supply to deliver 1 amp in 24V AC. Does that sound right? I have not been experienced with such long power cable run, and I am not sure if this is the right direction. Please advise. Thank you.

It looks as if the email alert and uploading image to FTP are done at the DVR itself, not PC program. If so, your PC would not need to be on all time. The only PC that does need to be on all time would be the FTP server PC. Couldn't that be what the joker at the shop meant?

Hello, gmcmurry. I recommend DV3 series from Nuvico. It does all of the above. It also offers DDNS, well written manual, and easy operation. I've dealt with many of them and I was delighted most of times.

Thank you, survtech. So use 16 gauge wire, and 1A power supply, correct? Well, if 18 gauge was the only option, what would I use, 1.5A? Can you tell me how to calculate that? I'd love to learn.

Hello, all. I need to install a camera that draws about 500mA, in about 200ft distance from the power supply. What would be the suitable amperage of the power supply? I am using 18/2.

Thank you, RickA, kalp.

Hello, all of you. I joined last month. I'd been visiting often before though. I want to learn and share what little knowledge I have.

Yes, that is the idea. To do this easy, use a terminal block as what Thomas and CollinR said.

In general, USB ports on DVR systems are for backup, not for connecting to PCs directly. In order to connect to DVRs from your PC, you would use ethernet port.

Is the port forwarded to a single port or a range of ports?
