what would cause image to distort?

[wozzzzza]

i think its a hikvision camera, cant remember model but a few years old, what you reckon causes the image to distort half the time like this??

Lots more info needed.
What do you use to record?
How are the cameras connected to the recording device?
Model number of recording device?

What's distorted about it?

 

[rdxny]

To me it looked like motion blur/vibration. What shutter speed are you using?

Second picture has a slight blur to it.

Thanks. I couldn't see it until looking at the room numbers.

I'm thinking it's the day/night switch, kind of looks like it's on the nighttime focus during the day. The little strip of purple on the left looks like an IR cut filter that may be sticking a little.

dahua NVR5216-19P-4KS2E
connected to a POE switch thats connected to NVR
camera is a dahua ipc-t3841t-zas

What's distorted about it?

look at the pictures side by side, look at the door numbers to start with, its fuzzy. sometimes its perfect sometimes its fuzzy

Use Compression H.264 or H and Bit rate set to CBR if you haven't.

worth a try, its on h265 right now and vbr

That explains it. H265 and vbr will do big "macro blocks" of the image when there isn't motion and will fuzz it up.

Can try turning off AI SSA in image settings if it supports it or WDR. Looks WDR related.

That's a good catch. Get on the camera and try forcing B&W / Color along with IR cut a few times. See if the strip moves or goes away.

so far switching from h265 to h264 has fixed it

 

[wozzzzza]

still doing it.

 

[Flintstone61]

could be switching from Substream to mainstream because of sensed motion. try turning down motion sensitivity maybe?

What are your image settings?

Does the double vision persist? Like it is on video for minutes or at least many seconds? Or is it just a frame or two?
