I am having the same issue with AI (Code Project) false alerts with static vehicles parked in the driveway. Has anyone been able to correct or reduce the false alerts?

I think it would be great if there was a way to leverage than Static object functionality without changing the mask region.

Can't the mask region be segmented into selected areas without changing the entire region? Looks like only a few pixels would mask the car..., what there is of it to be masked.

This brings up the possibility that the desired static identification functionality may be significantly impaired by both the size of the object and the fact that it is already obscured by both columns in the foreground. Combine that with the relatively small area, the appearance of the car naturally changing over the coarse of the day's lighting and weather effects, perhaps too much is being expected of the feature in this particular instance?

I love it when a plan comes together

And I will keep looking at that Static rule config until it gives up and works

I think the solution proposed by Pogo is a workaround....

As was it's intention -- until the next 'stable release' fixes the actual problem, of course!

I think the solution proposed by Pogo is a workaround (which to be honest I implemented in the meantime because missing some alerts is better at this point than receiving constant false alerts), but I think it would be great if there was a way to leverage than Static object functionality without changing the mask region.

Mask the location of the car's 'static' location. It then becomes a non-issue unless it either exits or approaches the masked area which would presumably trigger the appropriate action for the detected activity.
Masking out an entire area because of an object that's sometimes static there is 100% not the correct approach.
Please alert the masses when AI becomes a 100% correct approach.

The suggested method provided a simple and practical solution that could have been effectively applied to the problem in less time than it took you to type your first sentence.

I haven't tested this... but... does it make sense? Or am I way off base?

1. Unzone that area where you park the car from zone A.
2. Define Zone B with that same area you park your car. Either overlap a bit into Zone A or use another zone to overlap A & B.
3. In AI Static Analysis, add the object (your car).
4. Sense 'Exists'
5. Enable only zone B.
6. Low % for Min Conf, so it's always static? Or, High so it's never found? I have no idea.

This seems like a serious issue to me, at least in my case causing so many false positive alerts by AI finding a neighbor's light to look like a car, or whatever and setting off so many notifications that you stop even looking at the notifications, which defeats the purpose of having AI or even having cameras to begin with.

I'm actually thinking there is a bug involved here. I have my driveway and front yard camera set to check for static cars, and set a static car as a "Canceled Alert". It does indeed show up in my alerts list as a "Canceled Alert" (meaning I can right-click the alert and have the option to "confirm alert", whereas a normal alert with a moving car gives me the option to "cancel alert" when I right click it). Problem is that this "Canceled Alert" shows up in the Alerts folder and not in the "canceled alerts" folder in the windows on the left side, and it still triggers an alert trigger, sends a notification to my phone, and keeps the main stream recording for this time frame and not the sub-stream recording (wasting HDD space). It seems logical to me that while it is correctly being set as a "Canceled Alert", it's incorrectly being put into the wrong alerts folder.

Also, I did try setting a memo of "static-car" and adding that to the "To cancel" list, but then that means that when a person is walking around and a static car is present, the alert is still canceled instead of correctly being alerted due to the non-static person in frame. I also tried using "Occupied Alert", but that resulted in the same outcome as "Canceled Alert", except it has the occupied icon instead of the canceled icon. Prior to whichever update mucked up the static object analysis from a simple checkbox, "Occupied Alerts" would be sent to the canceled alerts list and never set off any notifications.

Mask the location of the car's 'static' location. It then becomes a non-issue unless it either exits or approaches the masked area which would presumably trigger the appropriate action for the detected activity.

Masking out an entire area because of an object that's sometimes static there is 100% not the correct approach. There are plenty of scenarios where you need to be able to get alerts from in front of a static object, but not alerts by the static object itself. A mask means there's an entire volume that stretches from the lens of your camera to infinity where AI can't see anything, not that there's a small area where the static object is that's hidden. Masking out may be appropriate for areas above the horizon where there's nothing but trees to needlessly set off motion and you aren't anticipating Tarzan to come swinging into your yard, but not for something that's at ground level and will obscure areas where notification is actually needed.

Hmm, I told myself to RTFM, and it has this rule that looks somehow useful:

I'm certain its purpose is intelligent masking rather than simple black out masking. One of my issues is reflected cloud movement on my car windscreen causing multiple CPAI "Car" triggers. Surely it can't be impossible to show the car isn't moving

I've just set up a rule. It didn't have any, so no rules = no static objects. This rule looks to be the opposite to what I'm after, so I'll try this for laughs:

Just thought it was basically the purpose of the static object funtionality and that there was a way to configure it 'better' to have it fit my need.

There probably is, but intuitive or intelligent doesn't seem to apply to how AI is actually designed. LOL

Hi.

Yes, this seems to be an idea to get around the problem.
Assuming the 'static' car parks at a very similar location everytime, I don't see a lot of downside to this option.

I am no expert, but why do you have static selected, it is my understanding that is to identify static object (ie not moving), is it not the movement of the trees that is the issue. What exactly are you trying to alert on from that camera, do you really need to detect the non moving car?

Hi,
Happy to explain. I don't want any alerts on movement of trees / shadows etc. I have programmed Blue Iris to only triggers alerts on motion detection where either a person or a car is detected. When my car is not parked there "permanently', this works fine. A movement of the trees and it's shadow would trigger a motion detected that would get ignore as no car / persons are detected.

Problem I have is that, when the tree /shadow creates a movement, the motion detection gets triggered and sometimes BI identifies the car, even though it didnt move for the last few days.

Desired outcome would be: motion detected, car detected, alert ignored given that car was there and hasn't moved in the last x mins / hours.

Does that clarify?
