IPC-HFW5241E-Z12E What is going wrong?

[mlapaglia]

This car is moving about 5mph and ~12 ft away from the camera, the plate has no dirt on it. why is the image complete noisy trash? it's like the IR isn't on or something

 

[mlapaglia]

Here's the existing hikvision installed facing the opposite direction

You really can't compare the two images. Different angles, distances, travel direction, etc.

If you do not think the IR is on, go outside and look. What firmware version are you running?

You might try this

is that plate retroreflective?

 

[mlapaglia]

yes, and very clean. when it goes by the other camera it's crystal clear. scratching my head.. it's 12 feet away shouldn't it be super bright?

did you post the image from the other camera?

3 possibilities
1. plate is not retro reflective
2. IR is not ON at full power
3. IR Cut filter is ON

I had problems with that firmware. Mostly cams going offline for about 2 minutes every 90 and not keeping the manual focus. Also had grainy captures and sometimes they looked out of focus but the focus value had not changed. So I went with the latest official version, V2.800.0000000.22.R, Build Date: 2020-11-19. My new settings below that seem to have solved all of those problems.

 

[mlapaglia]

i will give these a shot this evening.

i do have to say, with the zoom this thing has, daytime shots are awesome, even in 720p

 

[biggen]

You have a great install spot right on the road with virtually no angle. That is great!

I'm also having a bit of a hard time dialing mine in a night. I'm going to give @samplenhold's settings a try and see how that goes tonight.

 

[ajwitt]

I run with the sharpness down quite a bit and that knocked that grainy look out for me.

 

[mlapaglia]

Ok I dropped the gain down to 15, opened the iris all the way up, and upgraded to V2.800.0000000.22.R firmware




i guess i was hoping for a better image given it's got 4 huge LEDs on it, compared to the original hikvision with 1.

here's the hikvision camera, same position:

 

[bickford]

try with gain = 30 HLC 50%
manual IR to 100%

BICK

 

[mlapaglia]

gain at 30 hlc 50%, ir was already on full blast

much better this time, just a little overexposed. should i turn the gain or the hlc down?

 

[ajwitt]

I'd knock gain down - try knocking down by 5 and keep adjusting until you get the image you are looking for. Mine is horrible without HLC at 50 and I am not as straight on as yours.

 

[bigredfish]

I've found once at the point where you are with overexposure but good otherwise, it was a fine balance between Gain and Iris.. 5 unit increments until good

 

[bickford]

Yes you can try with gain to 25 %

BICK

 

[mlapaglia]

That worked, looking much better now, thank you everyone for your help

 

[mlapaglia]

oof lol

 

[bickford]

you have to use 2 settings , 1 for day and 1 for night !
