Can anyone publish some demo-video of this cam at the daytime and different focusing distances?
Thanks.
Thanks.

Thanks - I spent a lot working on this but still no luck.
I would definitely not recommend this camera with the auto-focus issue.
I don't understand why we can't just set the focus and it not change on it's own.
My camera is constantly out of focus.
Msg'd EMPIRETECANDY to purchase a Z12. My only other camera right now is a 3mp hikvision varifocal dome.

Man, the police came over today to see if I had footage of a car leaving the community.
My LPR (IPC-HFW5231E-Z12) was so out of focus, it was useless. What a crap camera...
I have to set the focus manually. With the settings it has for LPR, there's not enough light for it to focus itself at night.
Is this camera loose focus in the daytime or not？ This camera is not default as a LPR camera, all tested and researched by other members here and find this cost saving way for LPR. So maybe you have some setting wrong? What is your fw No? Maybe i can send you a new FW for updating?
Maybe you can refer to this posting.
Dahua IP-HFW5231E-Z5 LPR settings
I use a home automation software called OpenHAB. It calculates what time of day the sun rises and sets, and then sets the camera profile. I have different profiles for the time of day to get the best setting for the camera to get the best reading.

I have the IPC-HFW5231E-Z12 and found the Dahua IP-HFW5231E-Z5 LPR settings no use to me as it overexposes the night images, too much flare from lights and faded licence plates, tonight I set the shutter speed to 1/2000 and aperture to 34 and IR on manual 100% I'm capturing from 90 feet away these settings will vary for everyone distance being 1 factor to consider, I'm trying for a fast shutter speed and a good IR to light the licence plates up then using the aperture to fine tune other light sources out, tonight a car happened to pull up in my target area which was ideal when tuning my aperture.
The autofocus is an issue I wish there was an option to set a fixed focus maybe someone will do a custom firmware at some point otherwise it would be an ideal camera, I have set the night mode to come on early in the afternoon and switch off late on the morning this seems to help but sometimes find the camera has tried to focus in the dark.
The Image at the bottom with the washed out plate below is on the Z5 settings.

You can set the focus manually.
Get current focus state:
http://name:pass@10.0.0.XX/cgi-bin/devVideoInput.cgi?action=getFocusStatus
Code:
status.Focus=0.500000
status.FocusMotorSteps=644
status.Status=Normal
status.Zoom=0.877598
status.ZoomMotorSteps=433Find out what focus level works for you and you can set the focus:
http://name:pass@10.0.0.XX/cgi-bin/devVideoInput.cgi?action=adjustFocus&focus=0.500000&zoom=0.877598
I have a script that checks the focus every 5 minutes and gets it back in check if needed.

I use a computer running this script:
Code:
<?php
$login = 'user';
$password = 'pass';
$url = 'http://10.0.0.XX/cgi-bin/configManager.cgi?action=getConfig&name=VideoInMode';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "$login:$password");
$result = curl_exec($ch);
curl_close($ch);
$line = strtok($result, "\n");
$dingo = rtrim($line);
$checkdigit = substr($dingo, -1);
if($checkdigit == 1) {
$url1 = 'http://10.0.0.XX/cgi-bin/devVideoInput.cgi?action=getFocusStatus';
$ch1 = curl_init();
curl_setopt($ch1, CURLOPT_URL,$url1);
curl_setopt($ch1, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch1, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch1, CURLOPT_USERPWD, "$login:$password");
$result1 = curl_exec($ch1);
curl_close($ch1);
$line1 = strtok($result1, "\n");
$dingo1 = rtrim($line1);
$pieces = explode("=",$dingo1);
//echo "$pieces[1]\n";
if($pieces[1] != "0.165000") {
//echo "Adjusting focus!\n";
exec("curl -s -u user:pass --digest -g \"http://10.0.0.XX/cgi-bin/devVideoInput.cgi?action=adjustFocus&focus=0.165&zoom=1\" > /dev/null");
} else {
//echo "Focus ok!\n";
}
}

so this could be put into a batch file that starts automatically when the computer starts?
You'd want it running all the time to keep an eye on the focus. Mine runs every 5 minutes.

Are you focusing via the camera's web interface and have you disabled PTZ/control for that camera in BI?
