As per the title, I am seeking some guidance on what I am doing wrong here.

I've recently set up a 9 camera system with NVR for my home and I'm slowly learning my way around the not-so-complicated system. One thing that has me stumped is the AI Vehicle and Human detection part of it.

I am using a mixture of T180, 4K/T, 5442 ZE and 5241 cameras.

NVR is the 8XI.

Plug and play and straight out of the box without tinkering with any settings, the only cameras that seem to be doing the AI detetion are the 5442 cameras. For the life of me I cannot workout why or which settings I need to adjust to get the other cameras to do the same.

You're about 10% of the way there. Lots to learn

First, get out of the direct to machine interface of the NVR and log into it via a PC/laptop and a web browser if you havent already.

Dont try using the NVR UI to make camera settings. Each camera has its own unique settings and its own interface.

By logging into the NVR via web browser, you'll see blue IE icons on the camera registration page. These take you to each cameras web GUI where all of your settings should be made.

Once there, you'll see an AI tab for each camera that allows you to set a variety of rules

Thank you mate. I never in a million years would have worked this one out. I better dust off the old laptop and hope it fires up. It's been over 10 years...
 
Unfortunately the IE icons simply direct me to a P2P with a QR code that in turn directs me to download the DMSS app.

Just uncheck that and hit next.

That is part of the initialization screen.
 
Yep, uncheck and ignore
 
Focus on 3 areas in the camera GUI
1- under Camera go to Encode- set the encoding . Generally use a bitrate : 4MP 10,000, 2MP 8000, 4K-16,000
follow my screen for the rest. They can all be adjusted later. Dont use h.265

2- Camera-Image- lots of possibilities here depending on the scene, how much light etc. Basically Night is way different than day.
@wittaj has a great starter post for this

3- AI- this is where you'll use the camera's built in AI to detect humans and vehicles and ignore squirrels and clouds and leaves and shadows.. all the crap old fashioned Motion Detection does.
Turn off AcuPick and just choose IVS only
Setting up IVS Tripwires and Intrusion zones can be challenging. Keep in mind there is a 3D element to the lines you draw, so you want them to hit a human or car at belt height ideally. Too high and they can literally walk under it.

Yeah turn of MD and SMD if on. 10 year old tech

If I'm interpreting how this thread is going so far:
You want to turn off AcuPick and use IVS rules?


Motor Vehicle, Human, and Non-Motor vehicle search is a function of AcuPick (Video metadata).
Camera's with Video Metadata AI function on board are 5 series or higher. As well-as NVR5/6 -X/-I/-XI/-EI/-AI series and may allow one or more 'AI by recorder' video metadata channels.

As bigredfish has shown in the camera interface, turning off the smart plan for AcuPick/Video Metadata will stop it.

The 5442's have video metadata AI function built in.

You can change the area video metadata is looking at in the NVR GUI or Camera web interface.

Personally I like having Video metadata enabled for a channel.
Makes it easy to search every person seen on my overview camera. But I use IVS for intrusion alerts in other areas closer to the house.

Video metadata is what gave me these charts of activity on my street since 2022 (this is a previous year):

In the case of my neighbour's car getting broken into;
I used video metadata to search every vehicle that had entered my street in the weeks prior. The thief skated out their car ahead of time before striking at night.

I beg to differ about SMD. It's useful for the draw & search area function.

If you keep it on (you can and have other AI features running), then you can use the smart search tool. It's the motion detection version before AcuPick.
I have SMD enabled and can use the search function, even with motion detection not set to record in HDD schedule (I use 24/7 general recording).
 
Video Meta Data does not require Acupick. They are separate functions that CAN work together.
IMHO AcuPick is useless for a home residential user

VMD is great. I run it on a couple of cameras also, but IVS allows me to set specific alarms for Human/Vehicle/Critter as well as direction of movement and be specific as to what area of the scene I am interested in.

The perform two different tasks.

In the background it's the same system adapted. Dahua claim it's the next evolution of it....

OK but in current S3 cameras they are separate functions and VMD can be used without AcuPick. Currently they perform two distinct if complimentary functions.

I think the problem is the new S3 cams coming preconfigured out of the box with AcuPick and VMD enabled by default. IVS still has a distinct benefit in target selection for alerts, direction of travel, and size.

Interesting on AcuPick 2.0. It looks like a combination of marketing speak (which Dahua is becoming famous for) and trying to integrate various specific purpose AI functions into on big AI blob. I wonder if under the hood they'll continue to give us independent control of the various AI functions?

On MD and its AI overlay SMD, they are useful for "Smart Search" but the downside, particularly real world outdoors, is not worth the benefit IMHO. Still far too many false alerts for me to bother with MD/SMD outdoors. If my IVS and/or VMD is done properly I find SMD largely redundant, taxing of the camera resources if running simultaneous, and gives less useful intelligence. Not to mention the false alerts

I think the differences and newer higher level AI functions on by default are a disservice to new residential users. I prefer to bring them up to speed more slowly so that they can get a feel for the basic functions before trying to go deep into features that may indeed be cutting edge and cool for a larger commercial venue but are really just confusing for no great benefit for a home user.

But then I’m an old fart and old farts don’t like change so much :rofl:
