Looking for recommendations on the best wireless LPR camera. Got a light pole with a power plug, looking to point it at cars. Also, is there a way to decrease the license plate light, so it can read better, or is that built into a LPR camera. Running latest of Blue Iris with 12 cameras. Mix of them. Hikvision, Foscam, etc. Thanks.
Best Wireless LPR camera's

Reading plates is all about focal length, shutter speed, and angle of camera to plate.
Nothing special about the camera itself other than the ability to set parameters and the camera adhere to it.
You don't want a wifi cam for it though. Get a real camera and then use something like a nanostation to RF it back into your system. Using home wifi is problematic for 24/7 camera streaming as these do not buffer like Netflix and such.
Keep in mind that this is a camera dedicated to plates and not an overview camera also. It is as much an art as it is a science. You will need two cameras. For LPR we need to OPTICALLY zoom in tight to make the plate as large as possible. For most of us, all you see is the not much more than a vehicle in the entire frame. Now maybe in the right location during the day it might be able to see some other things, but not at night.
At night, we have to run a very fast shutter speed (1/2,000) and in B/W with IR and the image will be black. All you will see are head/tail lights and the plate. Some people can get away with color if they have enough street lights, but most of us cannot. Here is a representative sample of plates I get at night of vehicles traveling about 45MPH at 175 feet from my 2MP 5241-Z12E camera (that is all that is needed for plates):
See the LPR subforum for more details.

At the moment, Wi-Fi is all I got, unless I change my camera to another location, which I have. I see that camera has 5 to 60 focal length. Yeah, that would work. Does the degree of angle make a big difference? I guess I could buy that camera and put it where I have POE. Otherwise, I have to dig up the lawn and run Ethernet out to the mail box. Thanks for the heads up.
When I did a Amazon search, it also showed a Loryta Camera Z12E S2 V that looks like the Dahua. Is that a clone I could use? Thanks.

That's usually the better answer. I resisted doing it for a long time too but, after, I'm glad that I finally did it. Much better results.
I have another corner of the house, but a street light is there. Would that work If i put the above camera and put it into night mode maybe?
That is the exact Dahua cam, just rebranded as Loryta, which is the brand that Andy here sells. I have bought all of my cams from him.

Yes. At night you will be setting up like @wittaj mentioned above. B&W w/IR. But any visible light will help you out.

New to LPR? Considerations Before You Begin
Thought I would throw together a post on my experiences so far with LPR in an effort to help others that are considering running down that rabbit hole. There are some practical considerations you should know about LPR. I am approaching this from the position of using Blue Iris and Plate...

Introduction This thread is about my journey into LPR (License Plate Recognition) after having about 18 months of experience with IP cams and having quite a bit of my system finished. I am not an expert on LPR, or IP cameras either. But I have spent a lot of time working with my system and...
Use of Overview and LPR Cams to Document Midnight Vehicle Distributing Offensive Flyers on Lawns
We were out of town and I was checking my cams remotely one morning and noticed one of the Deputies that regularly patrol my subdivision had been at my front door. She has come to me a few times requesting video as she knows I have fairly good coverage of the streets at my corner. I noticed that...
Angle does matter - this guy came here wanting to know why he couldn't read the plate LOL - but the angle was the least of the issues LOL

Well, when the car makes the turn the camera, tha backside of the car is easily going one way, and the front side is pretty straight on the other way.

Yeah but the shutter is too slow and the angle is too wide also, so even if he turned the camera, the plate is too small and the shutter isn't fast enough.
To reliably get plates, the field of view has to be not much larger than the size of the vehicle- too wide and the plate is too small - and no higher MP cameras will not help either.
Focal length for the distance to the vehicle, shutter speed, and angle gets the plate.
Ultra Smart 2MP IR Vari-focal Bullet WizMind Network Camera Support Face detection,IPC-B52IR-Z12E-S2. IS THIS what I need from Andy?

That is the go to camera for getting plates. It was recently renamed.
I will send you a couple of pictures of where I can set it up. Pretty sure the corner one will work. The other setup I would have to run Ethernet under the grass, not sure I am up to that this time of year.
The picture with the car is the wireless cam that has power but no Ethernet. The second picture is a camera attached to my house with ethernet and covers the corner pretty good. I am thinking the corner is what I was use. Has a pretty straight on angle when they turn the corner either way.
That shot of the curve is looks very good, especially for the Z12E. Realize that if they are coming towards you and have no front plate, you will not get a plate at all. Realistically, one needs to monitor in both directions.
