Right now I'm only working with IVS, it seems I've got the hang of my scene.

What do you think...... This is a comparison between Backlight OFF and SSA/WDR (they are very similar) It is evident that the SSA is seen with worse colors and a more "dirty" image but it really works in image burns, my scene has a strong contrast between sun / shadow area. It seems that IVS...

By pure chance, trying to see how to activate light/sound warnings for SMD, I found an access from the SmartPSS app. Actually, even if you try to change the time played and/or the file always sounds alarm.wav only once, but something is something, for the warning lights I have not found an...

My intention was not to make a phone call either, it is in case there was a place where dahua collected requests or bug reports. Here I leave again the configuration that should be seen, to be able to use light/audio with SMD.

Here you can see the difference, in my IPC-HDW5241H-AS-PV camera there are no Warning Light and Audio linkage options. Therefore, the Active Deterrence system cannot be used by activating only SMD, it must be done with IVS rules. Does anyone know if Dahua would listen to this request? There is...

In this test, you can see how IVS-1 does not seem to be executed due to the strong contrast (burned image), the rest of the rules are executed perfectly.

Now that I understand how the algorithm works, I have defined these rules and it seems to work quite well. My daughter, being short, skips the IVS-1, but the rest activate them all. I don't know how these 7 rules will affect performance and cpu load.

I think that this is another of the problems that I am having, as I said, my scene is very close to the camera and we add that the detection has to be done in the Z AXIS, with the objectives to be detected approaching and receding in the same camera axis.

I have already managed to understand the procedure and it seems that I have done it correctly. The correct thing is to make the ruler horizontal in the depth axis (can we call it Z axis? ), as it does in the documentation and as you can see in my image. Now it seems with the verification ruler...

I totally agree with your contributions. Finally in my scene, it would be enough for me with SMD, I could even disable smart plan IVS. And unload the processor. But damn it!! Dahua did not activate the light/audio trigger in this firmware!! Who could I cry to? Will Dahua listen to this...

With a smaller intrusion area, it seems to work better, the problem is evident in depth of field, for an intrusion box to work well it needs not to be too close and of a size proportional to the view.

It's more effective, of course. But not perfect as I would like. Here you can see how effective it is with side scrolling from left to right, it works perfectly. But it works really badly and inaccurately, with the movements from back to front in the axis of the camera. I am sure that if...

I seem to be getting worse instead of better!

The SMD human detection works perfectly, but in this camera model Dahua has not felt like enabling the light/sound trigger. Regarding the suggestions of minimum/maximum size and filter of objects I have also tried with it. Although I have to say that I have never been able to trigger an IVS...
