Getting the hang of it
thanksYeah Andy had to rename them. But it is still the go to camera and the new chip is an improvement.
why did the camera had to be renamed?

let me rephrase
is there a similar HikVision camera?
I have got the dahua
now want to try hikvision to compare

Looking quickly, I suggest searching the Hikvision website for "deep" or "DeepinView".let me rephrase

Thank you.Last I checked hikvision didn't go past 45-50mm focal length unless you moved to a PTZ. It is the focal length that makes the Z12E a wanted and valued camera. Nothing special about the rest of it.
Zoom is what's special about the hfw5241e-z12e camera.Thank you.
Is there a similar HikVision camera if the zoom is disregarded?
thanks
Thanks.Zoom is what's special about the hfw5241e-z12e camera.
Thank youThen it would be any of their 2MP on the 1/2.8" sensors.
But like I said, what makes the z12E special is the large optical zoom.
Without that it is basically any 2MP camera on the 1/2.8" sensor.
Thanks.
For me, night image quality is the deciding factor for overall anpr.
Understand.You realize that unless you have stadium quality light, the image is going to be all black except for the plate:
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):

this is on a road, not expresswayPlease post some video or screenshots.
But expressways typically have lights and lots of other vehicles.
Most of us are in subdivisions without any ambient light and thus cannot make out a vehicle
yes different, we need to cater to all scenarios^That is pretty cool!
Unfortunately not the situations we have that we have the need for the Z12E.
yes different, we need to cater to all scenarios
the issue with Z12E is at night, can get over exposed or under depending on how (retro) reflective the plates are.
its a program we wrote.Is that a program you wrote or found to do that auto reading? Because I am assuming that isn't done within the camera or you wouldn't be looking at the Z12E?
