Cameras too high resolution to detect motion in a custom area?

[Jay2jay99]

I'm trying to set up an area in the cameras to detect motion but QNAP says that you can only monitor motion in certain areas if the feed is below 1920x1080, the lowest my cameras will go is 2304x1296.....Why can't high resolution cameras detect motion in only parts of their feed? I'm sure I'm missing something obvious! Screenshots attached.

Why can't high resolution cameras detect motion in only parts of their feed?

Because of the amount of processing power needed to analyse the video.

So much better to let the camera analyse the video and pass the event notification to the Surveillance app - that's what the cameras are designed to do after all.
They use their in-built special-purpose DSP (Digital Signal processor) to handle the work instead of a CPU.

Ah ok, thank you, I’ll have a look in the camera app instead, thank you.

The camera web GUI will give you the best ability to set up the needed configuration.

i'm having the same problem.
really want to use QVR pro as detection system because that works alot better then the system that is build in the camera.
Is there a option to use that?

That's unusual, IP surveillance cameras these days usually have a good choice of smart video analytics capabilities, well beyond the classic 'motion detection'.
What model and brand of camera are you using?

Motion Detection > Detection Settings > Select tick (Completed) > Motion Detection Settings > Detector > Choose QVRPro instead of Camera

My cameras are both set to the Camera setting.

I have a Linksys LCAB03VLNOD 1080p 3MP Outdoor Night Vision Bullet Camera.
Its a good camera but the motion detection software on the camera isn't that great.
You can configurate it good for the daytime detection.
But then the night is a different story.

Hello,

Thank you for the information but i allready know that.
I can't use QVR pro as detection because i need the resolution 2032*1536
I'm looking for a way that it is possible to do.

so you know your nas is not powerful enough and you dont want to do motion detection in cam ...so we have a stalemate here

[AlastairStevenson]

Its a good camera but the motion detection software on the camera isn't that great.

In what way?
Too sensitive - unwanted alerts?
Not sensitive enough - missed alerts?
No video analytics - just classic motion detection?

But then the night is a different story.

Looking at the specs - that's not surprising.
It's using an old low-sensitivity sensor that would only be usable at night with bright supplemental illumination, well beyond the built-in IR.

Minimum Illumination:
0 lux (IR On, B/W); 0.5 lux (IR Off, Color)

Current-model cameras achieve 0.0005 Lux and have smart video analytics that allow fine tuning of alerts.

Yes,

unwanted errors and if you decrease the sensitivity you get missed alerts.
This is way better with the QVR pro as detector.
Thats the reason i want the use the QVR Pro.

Video quality of the camera is great but that where it stops

Thank you for your support

I miss the statement that my NAS wouldn't be powerfull enough?
I just get a error in the QVR pro if i put my camera in a higher resolution and then want to do motion detection with the QVR pro software.
And this shouldn't be a problem hardware wise. it is just limited in the QVR pro software.

NAS is running in 10% load or something.

I gave it a try to use more streams. i saw my camera supports 3 streams.
Here i again bad luck that the QVR pro doesn't support my camera's 3 streams :-s

I have 2 4MP cams doing motion detection on iSPY software (10fps) ..they use 70% CPU on an 8th Gen I7 NUC (10k passmark) ..so motion detection in software, is extremly CPU intensive

so unless you have a ryzen qnap unit ..cpu speed WILL be the issue
