Choppy video on livestream and due to that motion detection is running always on these cameras (DVR).

Hi, I’m running Dahua DVR - DH-XVR5116HS-X model with 8 IP cameras connected to it.
Problem is that one of the camera, sometimes some of them is sending choppy video which makes the system detect motion always.
The choppy video appears on livestream and on records of course.
I tried restarting few times, I tried updating latest firmware.
It happens randomly on certain cameras, some are already good.
Attached example of the video.

Thats not likely a problem with your NVR but with your camera and/or connections.
Could be a throughput issue with a switch or router as well. You'll need to isolate each component of your network and narrow it down

+^1 What @bigredfish said ....also maybe, perhaps the hard drive is begining to "Flake out" or possibly Whack out. i,e. DIE.
 
try another drive for fun.
 
What exact model # is that camera in the video clip ?
 
It almost looks like electrical interference …

No i would think a nearby fixture . What model is that camera? Do i see red/blue flashing lights?
 
honestly I don’t know the model of the camera, no lights on the camera no blue/red flashing lights.
I took out the electicity plug of the panel (not the xvr system) that goes to the cameras and put it back in, and after that the picture is clear, it get messy over time.
 
Hmmm could well be just a cheap shitty dying camera then
 
Usually a tag on the camera itself

Coax?
I thought you said they are IP cameras? Are you sure they’re not HDCVI?
 
That would make more sense , if so it’s very likely a power supply problem
 
Yes, coax, I don’t know what HDCVI is.

Uploaded some images of the power supply that distributes power to the cameras (like a hub)
and the DVR box where you can see inputs go in from camera over coax.

Ok those look to be HDCVI (analog) cameras not IP cameras

It’s common to have interference like you have from power supplies or cables running close to mains power with analog cameras.

As a test, Take the power wires from that camera, connect them temporarily to a simple 2A 12v dc power supply and plug it into 120 outlet somewhere and it will likely clear it up.

It could still be old dying cameras but more likely the power supply.

Many thanks ! I will give it a try and report back !
 
I had Dahua analog systems for a long time and power interference was a constant problem. I finally gave up on multi power supplies and went to all individual plug ins.

Even slightly loose connections on the power or video wires can do that. Maybe Check each connection at the cameras and spray them with Deoxit if they look corroded at all

Worth a shot with Deoxit, whether you see corrosion or not, it may help as Deoxit will improve the connections.
