help with IP Camera models

[bigredfish]

Ok. Yeah as soon as soon as possible you need to access the web GUI of the NVR and individual cameras.

And All settings should be made in the cameras themselves, not the NVR. You don’t even have access to many settings for the camera image in the NVR. It’s a futile effort that will mean largely starting over.

I'm plugged in from my laptop directly into the back of the NVR ethernet port, but im having some trouble working out how this is suppose to work.

on the NVR TCP/IP, it says the IP is 192.168.1.108 and it has a default gateway of 192.168.1.1
I'm a bit confused what device is 192.168.1.1 ...is it suppose to be my home router...because my home router is 192.168.0.1
"Virtual Host" is set to on (not sure what this does)
P2P is enabled.

Cameras have an IP of 10.1.1.65 through to 10.1.1.71 (this NVR just auto initialises and assigns this once a camera is plugged in even though i have plug and play disabled)

Once I plugged my laptop into the NVR network port, I tried accessing all the above IPs via Chrome with no luck.
I then disabled my WiFi on my laptop to see if that was why, but i still can't access any of the IPs. using a macbook and chrome, tried with http/https://[IP] with no luck.
tried to ping and can't ping any of them either with and without wifi enabled.

You will need to change the NVR IP and gateway (router) to match your network 192.168.0.X, OR
change your router to 192.168.1.1 and its DHCP allocation to give out IPs in the 192.168.1.x range

The cameras are doing as they should. You can’t access them directly from your LAN. They need to be accessed via the NVR web gui and the blue IE buttons on the camera registration page

ahh gotcha, I got it working.

on the LPR, this is what I've set so far for night settings. i have the working mode set to day/night switch. how do I set exposure speed to 1/1000 ? the closest option I have is 1/2000

 

[kearkg]

exp setting

 

[bigredfish]

1/2000 may be fine, hard to say
If you scroll down on the list you should see Custom.
It lets you set a range in milliseconds
0-1 would be no faster that 1 millisecond or 1/1000


Lots of factors.

When I get home I’ll upload my settings. They should be viewed simply as a ballpark

There are two ways of doing this...
First are using very fast exposure times (like 1/1000 or 1/2000) to capture only plates..

Second is using WDR trick with much more normal exposure times (1/100 to 1/200) and very strong IR light...
plates are very reflective and should be very over exposure.

Full WDR (with values >= 50) is doing double (and in case of 5442 triple) shot for each video frame. First is normal, second is much faster (like 8-16x times)..

First one capture car / street at 1/100, second car plates and lights at 1/800 or 1/1600..
then WDR algorithm merges both shots to one frame.

Results from night you see below..
I know that my trick don't work very well in the US (very bad plates), but you can try in Australia..

 

[bigredfish]

And if you’re still trying to capture in color or B&W /IR

Two very different batch of settings

@steve1225 how do you get all the plates in one view like that?

this is AI Search -> vehicle search on any 5xxx Dahua NVR...
You must on 5xxx camera in SmartPlan disable AcuPick and after reset select and configure Video Meta Data...

it not only collect cars with meta data (color, brand, plate) but also humans, faces and non motor vehicles.. So you can browse/search by attributes them on AI Search -> human / faces / non motor / motor vehicles search...

here are some screenshots direct out of the NVR using @steve1225 WDR settings. tree should be gone soon, but plates are seeming legible.

those settings are base..
you can play with them...

I don't see rest of full video frame..
but shutter/gain settings will change how full frame with car/street look - you can try 1/200 (0.005s) as shutter speed...

IR settings (especially manual near/far) will decide how IR lighting distribute over frame...

here's the full video frame.

what can I use for daytime settings ?

half of video scene is grass...

you should move/rotate camera up...

the driveway with the car should be in the middle of the video frame..
