RLC-823 16x Shutter Speed

[brandoncarrolleet_691346059215349]

Morning,

I am trying to use an RLC-823 16X as a license plate camera and I've had good success during the day but night photos are unusable. Images are too bright and blurry

Is there a way to adjust the shutter speed? I see some other Reolink cameras can, but the setting appears missing on this one. Just updated firmware and not there.

Thanks

@brandoncarrolleet_691346059215349 Unfortunately it is no longer possible to change the shutter speed and exposure on Reolink cameras. These were available on the initial cameras.

Try to set the max bit rate and max resolution.

Already set to max bitrate and resolution. I'll have to find another product.

Thanks

@brandoncarrolleet_691346059215349 License plate reading is very difficult at night. Home security cams are not designed to do this. Some companies sell expensive license plate reader cams, some come with expensive software to analyze the footage to better ID the plate, some even do online searches to ID the owner, for a fee of course. These type of cams are used for high security, military, banks, prisons, etc. and road toll booths. At night the IR from a regular cam will reflect back from a plate making reading difficult. In order to have a chance the cam brightness needs to be turned down so the view is very dark, not much else visible except the IR reflection on the plate. Or turn off the camera IR or its spotlights, have IR or spotlight from a different source and angle so the plate can be seen better. Being able to adjust the shutter speed may help some motion blurr but not much with home type security cams.

@md

Perhaps reolink should remove this article from their website telling people to buy their product:

https://reolink.com/blog/best-license-plate-security-cameras/

"For example, RLC-823A PTZ long night vision security camera would be a nice option for reading license plates at low light conditions."

@brandoncarrolleet_691346059215349 I suggest you to take it up with support by attaching the recorded video. But as you stated it's not the fps but the shutter speed and exposure which are needed for clear pic at night time. I would also consider to have independent IR illuminators so as to avoid reflection and have more IR light.

@brandoncarrolleet_691346059215349 I had not seen Elvia's article. Much of what she said I agree with. The part about license plate reading may be true for daytime, but certainly not at night. I assume she hasn't really seen any testing or reviews of the 823A models capabilities in real night conditions with license plates, either stationary or moving plates. She should edit her post IMO to say reading plates at night is hard to do. In fact I've never seen any home camera brand advertise videos of quick night motion of a person jogging/running, a license plate on a moving car, probably because they can't do it very good. Below is link to The Hook Up YouTube channel testing color night vision with him jogging, one is a Reolink cam. All have some blurr, difficult to ID a face.

One Reolink cam may be better for reading night plates, the new low light CX410. I have one, I keep its spotlights off. There's enough ambient light from a street light two houses down. It can see stationary car plates pretty well at close range to about 25 feet. Further and they become blurry. If Reolink added this low light sensor in a 823A with optical zoom that would be really sweet. I like my Reolink cams, good cameras at a good price. I don't expect them to have professional features of expensive cams.

@joseph_1979 wish I would have seen this posts before I bought my camera. No shutter or exposure control? That is sad

@brandoncarrolleet_691346059215349 did you have any success? I'm using same as you the rlc-823 16x for license plate recognition and it's working very good during the day, but the night, even if I have good light, and the camera isn't using infrared and it's in day mode,but same problem of you, did you solve in any way?

[joseph_1979]

@giorginus80_589650454442009 Try to use powerful external IR illuminators and switch off the ir lights of the camera.

[Giorginus80]

@joseph_1979 I don't need ir illuminator...or yes? I attach

[joseph_1979]

@giorginus80 It will definitely help but there might be reflections on the plate.
