Great article :) I would love to see more Boolean logic applied to reduce false alarms for video analytics. If a "person" and a "line cross" and "loiter 30 seconds" then Alarm.

Thank you for the good review. Two comments:

1. I would like to see how AI seeks to address false alarms caused by nighttime insects flying close to the cameras and crawling on the domes (e.g. moths). Perhaps a screened enclosure with a few IPVM-trained moths (ha ha).

2. For those of us that live in bear country, can Hanwha's (or others') AI settings be adjusted so specifically to allow alarming on animals but filter out other false alarms?

For #2, the camera is currently designed to detect people/faces & vehicles/license plates. The design is to detect people and not false alerts from animals.

This will undoubtedly increase crimes committed in bear costumes.

This should be tested for validation.

Ethan: what is Rob's clothing size? I'll have this drop-shipped:

The camera was up for several days outside, with IR on, and did not alarm on any insects. I'll see if we have some video from that.

IPVM,

FYI, Hanwha has a search plugin for milestone for this camera. It can be found here HANWHA AI Camera Metadata Plug-in

Josh, thanks! We're planning a separate test of that plugin and others. There is a Genetec plugin and integration to Hanwha Wave/Nx Witness. At the time of this test there were some issues and limitations to integrations and not everything was working properly, which Hanwha expected to be addressed in the next couple of weeks.

Thanks for the article. Very interesting, indeed. I was really looking forward to Axis having something with object analytics by now, but alas...

Well, I guess that is progress. But "...BriefCam edge analytic initiative is underway with availability targeted for H1 2021", with no specifics yet, to compare to existing offerings, not to mention that they are way behind. That's coming from a guy that loves Axis and uses almost nothing else.

What were the results of object classification at night or low light levels? IR on IR off? Distance? Forced to stay color or B/W? Noise overload AI & Metadata push to server?

What were the results of object classification at night or low light levels? IR on IR off? Distance? Forced to stay color or B/W?

Classification performed the same at night using the integrated IR of the camera and detected at the same PPF as it would in day. I just walked around in a parking lot in ~4lx (measured on me) with the camera forced to day mode and it dropped the detection to ~22 PPF (~90' with the fov at its widest) so you do lose detection distance in a lower light setting in color mode (distance shown below).

Noise overload AI & Metadata push to server?

Are you asking if noise in the scene caused false alarms? If so, I did not see any of that during testing.

You mention 10ppf, but it's not qualified.

Is that daylight, nightime, etc?

James, it is ~10 PPF both day and night as long as there a person is clearly seen, also to increase detection distance the minimum size of detection in the common setting needs to be lowered.
