Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
I am mostly interested in a DVR with Dahua software though. I also want the same Alarm IO and Smart features (face detection, missing object, smart search) that the Dahua DVR offers. It is very hard to find this with Lorex systems though. Any other suggestions?
Here is a link for the DVR that I am looking to buy: [url]https://www.amazon.com/gp/product/B072DX5417[/url]
The only issue is that I have no idea if the seller "Q1C1" is authorized.Re: CCTV Vertical Coloured Lines Rolling Across Screen

Unfortunately I do not have any monitors supporting this type of input. I tried a video/bnc adapter but the video did not work.Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Do you think it is some type of power interference? Do you think having multiple cables running next to each other is messing up their power and causing interference?...Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
So are you saying my DVR is bad quality and it is causing the lines? I was thinking of upgrading it to begin with but I guess now I have a reason for it now. Now that you say that, the cameras do glitch whenever I tap the Bnc connector on the back of the DVR....Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Sorry, I did mean that I tested it out by removing the power lines. I will try out your method and let you know the results. Thanks!...Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
I actually have the cameras set up to the power supply now. I will try to disconnect each video line separately though and see if there are any differences....Last edited by TornadoAlley101; 04-07-2020, 09:19 AM.Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
So if it is possibly a ground loop, is there a way to test it out to confirm it?Leave a comment:

I purchased the system on a lightening deal. Be more helpful next time....Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
It is a cable sold by ZOSI themselves. It should show all the specs so here is the link: [url]https://www.amazon.com/ZOSI-Extension-Surveillance-Security-Connectors/dp/B0185MMPP2[/url]

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
I am afraid if it could actually be a ground loop. The ground loop isolators cost up to 15 bucks for just a 2 pack and with 16 cameras this could be very expensive. I wish I could get a sample isolator so I could test this out first before I go off buying 16 isolators....Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
I have multiple BNC cables running side to side next to each other at some locations. Will that cause problems? I really hope that isn't the problem because the areas where they are together are the only areas they can run. Also, the lines roll sideways (left to right or right to left) not upward....Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
I disconnected the UPS system from the voltage stabilizer and nothing has changed. The UPS is directly connected to the wall outlet but there is no change in the lines. The description says the voltage stabilizer's maximum capacity is 1200VA @ 600 Watts....Last edited by TornadoAlley101; 04-03-2020, 05:32 PM.Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Ugh, I purchased the 10A Power Supply and the lines still persist. Help!!!
I feel like my outlet is underpowered or something. I was going to try testing it with my voltmeter but it is broken. I feel like I am going to end up dropping a lot of money on this if the problem keeps up. I really need some professional help on what to do.Last edited by TornadoAlley101; 04-01-2020, 11:14 AM.Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Here are the links for the power supplies I am referring to:
[B]20A[/B]: [url]https://www.amazon.com/Channel-Distributed-Security-Surveillance-18OutPut/dp/B01MZ880XT/[/url]
[B]10A[/B]: [URL="https://www.amazon.com/Channel-Distributed-Supply-Security-Cameras/dp/B07QXXY987/"]https://www.amazon.com/Channel-Distributed-Supply-Security-Cameras/dp/B07QXXY987/[/URL]
It seems the cheaper 10A Power Supplies are less quality so that is why I am aiming for the 20A.

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
Also, will purchasing a 10a power supply benefit my cameras by providing more amps than required? Is it possible I could also buy a 20a 12v power supply instead? For some reason they are cheaper than the 10a power supplies but if the 20a will mess up my cameras then I can go with the 10a instead.Last edited by TornadoAlley101; 03-26-2020, 02:19 PM.Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
I just tried it out and my 12v 0.5amp power supply worked but I have a few questions after I dug deeper into the problem. I decided to unplug all 3 power adapters except 1 and when I unplugged the 3rd one, the lines became less visible on the 4th power supply's cameras but still faintly visible that it was still an issue. I have a lot of devices connected to one outlet including a wifi router, wifi extender, UPS system, power stabilizer, and other devices. Is it somewhat possible that all of these devices are leaving...Last edited by TornadoAlley101; 03-26-2020, 01:59 PM.Leave a comment:

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
[I]Update[/I]: The camera take in according to the company is 300mAh/0.3A and 12V. Is the 10A Power Supply still suitable? Will the extra 300mAh affect performance?
--New Power Consumption Chart--
[B]Power Supply[/B] mAh per camera (10A Total)= about 600mAh
[B]Required[/B] mAh per camera = about 300mAh
[B]Left Over[/B] mAh per camera = 300mAhRe: CCTV Vertical Coloured Lines Rolling Across Screen Interference

Re: CCTV Vertical Coloured Lines Rolling Across Screen Interference
So I basically need the 10 amp 16 channel power supply?
10 amp/16 channel= about 600mAh
20 amp/16 channel= about 1,250 mAh
Required mAh per camera = about 500mAhLeave a comment:
