DVR channels looks fuzzy

Hi all,

i have a Samsung SRD1670DC which recently started having issue on two inputs. it used to work flowless, settings were not changed for the cameras input so I'm a little puzzled by this.

The issue is that out of the 16 channels two are very fuzzy, the pictures attached will explain better the issue I hope

note the difference between the images.

The DVR has latest firmware (1.08xxx) installed and the problem is only on two channels which makes it strange as I thought the SRD has 4 trunks of 4 channels each so I expect this problem to be on 4 channels not two.

If anyone have any ideas please share them. Thanks!

Can you look in the settings of the dvr and see what the recording resolution is set for on those channels?

If you try a different camera in that same channel is it also blurry? Have you tried rebooting the dvr? How

old is it, maybe it's on the way out?

Recording is turned off for this dvr.

Looks crappy no matter which cam is connected to.

Only on 2 channels.

Dvr less than a year old.

Tried factory reset of settings and firmware flashing already.

Tried reboot and 30 minutes off to let capacitors cool down. Same result.

Can you still check what the recording resolution is set for on those channels even if recording is turned off?

Yep its set on CIF. Why do you think its related?

Not sure about samsung, but if you set the recording ratio on a Dahua to very low, than it displays the camera

at that resolution. I always complain to myself that even if I want to record a camera at lower resolution, why

couldn't it at least display normal?

Good thinking ill give it a try and see if it affect it.

Its a D1 display/D1 recording unit

I already rules out the baluns, cat6, and camera so it got to be something in the dvr. I just really dont want to send it to repair as I think they send it back to Korea. Last time I had to send Samsung unit it took me almost two months to get it back...

Set those channels to D1 and give it a shot
