Cameras starting to Pixelate. - Solved!

Example vid:

Hi

Ive startet having a problem with a couple of my cameras.
They start pixelating a few seconds after they start recording.
I have DS-2CD2132F-I cameras.
I have not had this problem in the past.
Ive tried different video settings without luck.
Anyone have any idea what could be causing this?
Maybe firmware problem, or Cold?
Its only minus 5 here tho, and cameras are listet to minus 30.
They have the lateste firmware.

I would reset them and see what that does. -5 they should be able to cope with fine, many here have done that!

Looks like the camera switches to substream after a motion event but the pre-event frames are still from the main stream? Just for giggles try changing the substream resolution to something higher and see if that improves things. It's not a fix but will confirm what's happening and give you a place to start looking for what to change to get it back the way it was.

I had similar issue with motion detection. Turned out nvr has event stream which was set to low resolution.

Ive tried doing full reset of the cameras that does it, with no luck.
I also run max res and quality settings on substream, so it looks way better then what you see in the vid/pic, so cant be that.
NVR event stream sounds interresting, tho it looks like this both on the NVR playback and on the cameras SSD playback.
Im guessing that the NVR's event setting wont transfer to the cameras memorys recording? But will test/check.

@klasipca
You saved my day!!!
Turns out the event setting in my NVR was set to only 32kbps. I raised it to 8192 and now it looks great
Also playback from SSD in camera is crystal clear, so NVR event setting effects cameras own internal recording.
Thank you for the help!

Been there, I thought my cam had firmware issues initially (it was my first Huisun)
