fine tuning assistance with IPC-HFW5231E-Z12

[trauts14]

My cam is getting great vid of license plates on 90% of vehicles that pass at night. Some cars have very bright brake lights that make the license plate vid/pic hard to read. My night profile has "Backlight" set to OFF. Gain is set to default which is 50. Any suggestions as to how I can fix this is appreciated. One pic of a "bright" license plate is attached.

I'm in the same boat. I have just got it a few days ago and I'm playing with the settings. I'm trying Kevin's settings, but they don't seem to work right. Image is pitch black, lights ar OK, not blinding, but I just can't decipher the plates. To grainy.

 

[Tibor Makai]

OK, I have measured in Google Maps. 31Ft to the street and 192ft, to the spot where I have zoomed in the camera.

 

[trauts14]

can you not zoom in closer to the camera?

 

[Tibor Makai]

It is all the way zoomed out.

This camera, should have visible IR light(s)?
No matter what I do with it, I can't see any light at the front of the camera. I have even tried a phone camera, to detect IR light and still nothing.
I have done both resets, just to be sure. Everything is on auto, on default. I know, if I chose color mode, IR won't work, but that is not the case.

IMHO you dont have near enough lens to read plates reliably at 192' with a 5231. Im using a 60mm lens at 120 ft

 

[Tibor Makai]

What do you mean, with a 60mm lens? This one, has up to 65mm.

 

[bigredfish]

Sorry missed that, didnt see the Z12

Do you know, where could I find a firmware for this camera? Dahua site, does note have one yet. I'm thinking of re-flashing a firmware, to see, if the IR will turn on or not.

firmware wont affect ir...how are you powering the camera?

 

[Tibor Makai]

POE+ switch and I have tried, with a 12V power brick as well, same result.

 

[Tibor Makai]

OK, I'm back in business.
IR connector, was unplugged.
I have just opened up(Andy allowed it) the camera and the wire harness with plug, just came out easily.
I guess, the connector wasn't plugged in all the way.
Since I took it apart, I took a couple of shots:

Have you tried Backlight=HLC at night? Also, please post a daytime image of a license plate. thanks

 

[crc2004]

What did you do with the IO port wires(5 small wires)? Do they need to be sealed so they won't short out on each other?

Firmware is under the downloads tab on this page. I'd check with Andy before updating the firmware.

I have already updated the firmware and I haven't seen any issues. I have purchased it from Andy.

You've got your gain set way too high. You shouldn't be able to see the car's bumper. Here's what my images look like with 1/1000 shutter and 12 gain:

Nice image, please share your other camera setting too.
