200 feet... and powering 3 cameras over two UTP cat5 cables. Yup. Try using a good cable. I'm using totally separate 18-gauge wires(pair in a shielded sheath) for power. Videos signals are going down Shielded Twisted Pair (STP) Cat5. None of the cat5 pairs are being used for power. Do I need to buy baluns with a certain rating/specification? Do balun ratings need to be matched to cable length? Do cameras all need to be the same make/model? Are the signals somehow different if the cameras are different? Is it possible that signals are bleeding into neighboring wires via electromagnetic field inductance? If so, should I run the signals down a specific set of pairs or limit the number of cameras on each cat5 cable?

So today I ran a totally separate thick gauge power wire for all my cameras. That may have have solved a volt-drop problem I think I had(Cameras draw more power at night due to IR-cut LED's turning on. New wire seems to have fixed odd night-time distortions on camera screens). But I'm still getting some slight drifting waves/lines on my screen for some cams regardless of light levels. They all have baluns and some have GLI's. I just can't figure out how to make this interference go away. Do I need to buy baluns with a certain rating/specification? Do I need to match it to the cable length? I'm using passive baluns and the furthest camera is a only couple hundred feet away at maximum. Do my cameras all need to be the same make/model? Are the signals somehow different and are being induced into neighboring wires via electromagnetic fields?

Okay, but, I've done several installations all using the same types of cameras and cable, yet I get different results with signal quality. I'm trying to determine what the factor is that I'm missing. Does the proximity of the video wire to a power wire have to do with signal quality? Inductance is the only reason I can come up with. At one house, I hooked up 12 cameras over cat5 cabling with zero baluns or GLI's and the picture quality of all cameras was perfect, so I know it's not as simple as "cheap parts, cheap labor, cheap results". There's a missing puzzle piece here.

I have a typical KKMoon Chinese Ebay 8-channel DVR, 6 normal cameras connected to BNC ports and 1 IPCamera connected over the Local Area Network. In order to show the digital cam (IPcam), I have to go to my menu-->System--Digital-->ChannelType settings and select a configuration which supports the IPcam. BUT what I don't understand is WHY I can only have 1 IPcam, and 2 regular cams, or 8 IPcams, 0 regular cams, etc. Why Can't I display all 6 of my regular cams AND the IPcam? It is an 8 channel DVR, I don't see why I should be limited to 3 displays when I want to view both types of cams. Anyone know how I can change this? Thank you.

Unfortunately this seems to be a common issue with these DVR's. I also have a crappy chinese ebay DVR, and they are so rampant, that I'm not even sure where to find any DVR's that ARENT chinese. Expecting to be able to communicate with their tech support (if any) is a futile endeavor, and aftermarket software is still something I'm hoping to find. I have a KKMoon DVR and wish I could update the software on it somehow to make it compatible with other browsers besides Internet Explorer. It depends on obsolete junky Active-X plugins and I can't even remote view it with Firefox or Chrome, only terrible IE.

Hi, does anyone know why my security camera images sometimes get these Red/Green/Blue lines? Unplugging the power to the camera and plugging it back in solves the problem. The connection doesn't seem corroded, voltage always tests fine. Why does this happen? Sometimes I can go weeks without seeing the RGB lines, sometimes it happens every 1-2 days. It seems to happen after the camera switches from color to Black/White mode. I've seen it only happen to specific cameras. It's not a problem that jumps around to other cameras. Thanks in advance.

Oh, thank you for that information!

I have a KKMoon DVR as well. I am still trying to figure out how to get the whole web-interface thing to work on mobile. I have successfully figured out how to bypass their "xmeye" cloud server, but the browser interface requires an ActiveX plugin to work. So far I can only get it to work on a computer, and Internet Explorer works most reliably, oddly enough. You can, however, open the camera streams with the VLC app on your smart phone, assuming you have the ports forwarded on your router. I have forwarded ports 554, 34567(media port), and 8110(dvr http port, default is 81) forwarded to my DVR's IP. With VLC you need to open an RTSP network stream with a URL that looks like this: rtsp://10.0.0.13:554/user=admin&password=&channel=1&stream=0.sdp?real_stream--rtp-caching=100 Obviously you'll want to put your external IP there(assuming you want to view your cams away from home), or you can use your local network IP if your phone is connected to your routers' WiFi. Change user and password to whatever your DVR is configured with. Mine is Just "admin" and blank password. Channel=1 means it will play stream 1. Change that number to whatever DVR channel you want to view. I know it's tedious and not very good, but I will let you know as soon as I figure out a better way.
