Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

Got an email from Andy today saying my camera has shipped. Mine was ordered through Ali Express as I already had an account with them.

Been using my HDW5231R-Z's for a couple of weeks now and am having some issues I can't fix.

1. I am having very bad ghosting at night
2. During the day I get very bad choppiness of cars driving by and kids running up and down the sidewalk.

I've posted my settings for any input

set the exposure back to auto...you need to know what these settings do before messing with them..

Dunno if it will help but I frame should match the frame rate, even though these cameras double it automatically.
 
I've never been a fan of 30fps for security. 15fps is plenty, imo. And I think I've heard the above advice before too so try that. If night ghosting doesn't clear up you might have a noise reduction type setting too high.

The latest firmware is supposed to help motion blur at night and it seems to do such things; but I run all my cameras on the defaults AutoExposure.. in Daytime it seems the white balance is alot better too..

I dont normally suggest firmware upgrades too those w/out the skill for recovery; but this last one seems pretty worthwhile to apply since it results in better performance IMO
 
do you run default exposure settings at night too? ill try to post a video of what I am experiencing both day and night - i may be expecting too much or just have something completely out of whack

im running Auto exposure both day and night; the only thing im using profiles for is forcing it from color to b&W mode at sunset/sunrise; because its too sensitive and wants to flip back and forth at dawn/dusk
 
just reset one camera to all defaults - will test again today and tonight. My cameras came with the NTSC firmware but I noticed the most recent firmware on the first page of this thread is for PAL - any reason to not try the PAL firmware on one of the cameras
 
it'll convert it to PAL but there's no reason why PAL will cause any issues.

Forgive my probably ignorant question at this point, but how does it know sunrise/sunset - that which changes throughout the year? Newer cameras have more ability than a time setting for profiles?
 
im doing it externally with my automation system using the HTTP API's
 
h264h shouldn't cause BI any grief..

Okay I'm new to this so also learning as I go. You've specified Manual with a Customised exposure range of 0-100 milli seconds - so 0 to 1/10th second. That 1/10th will be part of your motion blurring issue at night. If you want to run Manual (I do to prevent motion blur), try something like 1/25th second (40ms) or faster.

There's also a setting for the Gain of the sensor, which by default was set to 50 on mine. To get any decent low light performance I had to bump mine up to around 80. (I am running mine locked in colour) After that, I enabled WDR at a low setting and I adjusted the 3D Noise to get the best reduction in picture noise vs motion blur.

Save the settings (or write them down) before changing things in case you have trouble reverting back. eg. I found if you select "Normal"- instead of "Day"- it locks out your Manual/ Customised Range option for the exposure time.
