Bad settings ?

[bickford]

Good morning all

I have guys who passed last night in front of my house
but I think the picture is not good.
This is a HDBW 5231RZE with IR max and 1/75 exposure

Do you think my setting is bad? I have the feeling that the infrared is not powerful enough.

The camera is 5 meters from the guys


Thank you

Looks like some motion blur..

What are your DNR settings?
What bitrate are you running?

Can you post a video clip and your settings?

 

[bickford]

here is the clip :


yes there is motion blur but with fast shutter picture is very dark .




Thanks

More light,
Try the next faster shutter speed.
Set IFrame to same as FPS.
Reduce NR to as low as you can stand it.

Hi Bick, I didnt notice it was you at first. Hope all is well.

Agree with @looney2ns but at only 15ft that should be better. I wonder if the white light off to the top left is making the IR dim, like Smart IR? Its as if the IR is having little to no effect. At 15ft the 5231 should have plenty of IR.. Maybe set it to manual..

I would also match Iframe to FPS and try CBR

Will try this thanks Yes all is ok for me

I have the same camera and I'm having similar adventures trying to find an optimal combination of settings. At the moment I'm trying it set to Shutter Priority mode in Exposure, with 0ms - 7ms shutter range, and noise reduction just a couple points past the bare minimum (set to 10 in my case). Moving objects are trailed by ghosting. In color mode, it gets much more pronounced, so I'm sticking with B/W.

I've also experimented with manual Exposure settings, which lets me set a Gain range on top of the shutter speed. Reducing Gain brings down noise, but also makes even my very bright scene too dark. For reference, the attached photo is from a camera two stories above my Dahua, a Bosch 7000 Starlight, showing how much white light I've got with the parking-lot floodlights plus spotlights. Ideally I'd use a shutter of 1/200th or 1/250th, gain at 50 or less, and run full color, but my 5231 can't do it. My 5442 probably could, or my Hik DS-2CD2385G1-I, or my Bosch 6000 Starlight. The reason the 5231 is even being used is the 13.5mm lens, it has the range for what I am doing.

Going back to your own scene, they were walking quite fast across the scene. If they had stopped to try opening the car doors or look inside of it, your camera would have had a much better chance at identifying them.

News settings :
A little better






Flood light led ON :



Flood light led OFF IR ON MAX

Much better Bick

you counsel try HLC to see if it will reduce the flare from that spot light on the top right.... worth a try

 

[bickford]

Yes or i can break it ... lol

I have done a little mistake the distance beetween cam and me is about 7 meters

Another tactic for reducing blur would be to move the camera to a location where a moving person is walking toward the camera as much as practical, rather than across its field of view. Since your cam is varifocal, that could be worth considering.

Not too bad,
I would probably add an external illuminator and I think you'll be fine.

I like to go big so I'd probably use this one
