Night LPR settings - some are too bright, some are fine
The visible light(license plate light) is washing things out. You need to tweak exposure for ir light. try a locked 35 or 30 gain, lower shutter to 1/1000 May need to lower the exposure comp too -

Using the HFW5241E-Z12E LPR camera with a Tendelux IR Illuminator
Did you turn the camera's ir off? Are you going for wide angle coverage or long distance? -
Using the HFW5241E-Z12E LPR camera with a Tendelux IR Illuminator
To add the picture from my thread where you can see the scene/street are slow fixed shutter like 1/30 just for test and ensure I'm getting additional illumination. The lpr pix you see are same as with wittaj just a bright plate barely seeing the car if at all at like 1/1000 shutter -
Using the HFW5241E-Z12E LPR camera with a Tendelux IR Illuminator
No... Don't get the lonnkey. The lens aren't standard 20mm lens. Any of the one like the tenndelux but from the front you can see the pcb should be able to swap lens. But since you are already getting good result don't think you need that added IR. By the time you get bright enough to see... -
Using the HFW5241E-Z12E LPR camera with a Tendelux IR Illuminator
I'm surprise at 70ft you need additional IR illumination, one of my z12 is at 100ft on internal LED just fine Are the lens of the LED potted in black epoxy? if not you can swap out the lens for a tighter focus. I imagine for 70 ft you will probably want a 15-25 degree lens. better focus on the... -
VCSEL IR Laser 850nm illuminator for long distance spot IR 250+ ft
I used a sharpie to tint the sensor and that helped a little thinking to either build a hood out shade of some sort or tape it over completely and use a smart outlet plug that I can program to match my camera's switch time- Bitslizer

NDAA compliant camera for LPR use
Last I heard and I don't think it is related to NDAA was the EO on Tiktok and WeChat is being revoked, so yes some are related to China. I'm not saying this is good or bad either way, just answering your question -

Need Help tweaking HFW5231E-Z12 for night @ 240ft
it is an nice option if you have the power/illumination budget. Considering the goal being to maximize IR illumination, and camera sensor being less sensitive to 940nm resulting in dimmer image...... its also got a 45-60 degree spread, I think if i used that for my use case, it would be worse... -
Need Help tweaking HFW5231E-Z12 for night @ 240ft
Going to drop this here.... The power of 15w of 7 degree IR laser. With the high beam causing this much lens flare, The z12 alone or even with the V1 had no chance in hell of getting this plate -

So.... the 9 laser chips illuminator arrived today, it works and it is good! run lurk warm (not hot at all, i can hold forever) even in my chilly basement but since it will only be on at night with no Sun, that should not be an issue. Same great tight and bright as the 4 chips one. I was able... -

Using IR illuminator with street light and ambient light
His plate shot looks alot like B&W with no IR, we know he's using IR, thus if its a used cam (5231 are old after all) it is possible the IR cut filter is not working -
Using IR illuminator with street light and ambient light
Please post your night exposure setting. Frankly at less than 100 ft you shouldn't need supplemental IR Was this a used camera you recently picked up? I'm wondering if the IR cut filter is working correctly -
VCSEL IR Laser 850nm illuminator for long distance spot IR 250+ ft
I tried and couldn't find these hexagon housing laser lens anywhere(AliExpress ebay, digikey...) Maybe in using the wrong search terms. I did messaged this seller before and he don't sell the lens separately. He is willing to customize the power and I think the next step up is 30 degree lens.- Bitslizer

Need Help tweaking HFW5231E-Z12 for night @ 240ft
660nm is in the visible red spectrum, better to use a white light at that point. It also depends on the wattage of the output, regular laser pointer are in the mw range where did illumination (not collimated in to a laser beam) we are in the 1-3w range I did a review here with a ebay link for... -

Need some Godly help identifying a couple of good cameras for a simple 24/7 NVR setup for license plate identification
So what is your budget? Andy is running a sale for memorial day and the z12e cam will be $220 each. Ideally you would have 4 cams, something like this, all with at least 100ppf, 100-130 ft which are very much within the sweet spot for the z12, assuming mounting height of about 10ft. Should... -
VCSEL IR Laser 850nm illuminator for long distance spot IR 250+ ft
I messaged the seller, The seller is willing to customize most of the other similar infrared illuminator he carries with vcsel laser. Roughly extra $1 per pieces of laser chip. Slightly more than $1 per chip with less number of chips and slightly less than $1 with more chips. :love: Although...- Bitslizer

Need Help tweaking HFW5231E-Z12 for night @ 240ft
So night #2 with laser, I'm happy to report that I'm pretty much capturing everything but those weird, damaged, or paper plates. I was able to up my shutter from 1/500 to 1/1000 and lower my gain from 35 to 30 (lower the gain the less noise/grain but you need more light). The only challenge... -

VCSEL IR Laser 850nm illuminator for long distance spot IR 250+ ft
Here's the best I can do, note that the LED looks brighter because it has more scatter/diffusion and less focus than the laser, I'm no where near the "hot spot" focus area of neither illuminator. Captions in the picture refer to how it look to my naked eye compare to the camera picture- Bitslizer
