Wireless camera - multiple triggers - which settings 'win'?

PaulOckenden — Mon, 03 Oct 2016 03:46:00 GMT

In a multi camera setup it's often recommended to set up parallel rules:

If cam A detects motion record on cam A

If cam A detects motion record on cam B

If cam A detects motion record on cam C

If cam B detects motion record on cam A

If cam B detects motion record on cam B

If cam B detects motion record on cam C

If cam C detects motion record on cam A

If cam C detects motion record on cam B

If cam C detects motion record on cam C

Which is fine (if a little clumsy).

However, those first three triggers all look at camera A, and each can have a different sensitivity setting.

Is that actually possible? Are the cameras inteligent enough to use the PIR with multiple sensitivies at once? I somehow doubt it - surely it'll just be sitting there with a single detection threshold for the PIR.

In which case, which of those first three rules sets the threshold for camera A?

(If only we could do "If movement detected by camera A then record with cameras A, B and C)

Each camera can have a different sense level, but in the above, the ONLY sense level used is the one in CAMERA A, the second half of the rule only dictates which camera it records on ( sense level of that camera makes no diff )

I agree, but with those three rules the trigger for each one of camera A, yet they can all have different sensitivity.

But I'm sure the cameras done actually support that.

I'm just running some tests to prove my point (or not!).

tho, once the cam starts to record the other triggers do nothing as the recording cam locks out till done

Sure, but if I have three triggers all pointing at the same camera, each with different sensitivity, which one 'wins'? The camera is sitting there waiting to detect motion - it'll just have a single sensitivity - but from which of my triggers? The first one in the list? The last one? The most sensitive?

The PIR seems to be more sensitive on the edges to motion ( ed guess that the greatest change happen here )...

So the only real way to test above would be if 3 cameras are side-by-side to test ( detecting the same thing , at the same distances ).

And, that wouldn't take in to account the samll differences in each camera build ( one may just work better than the other )

I enjoy testing, but I think you may be over thinking this.... unless your trying to do a specfic thing and it isn't working but should.

I know it took me a few tries with each camera to settle on what works best for me re their locations. I also only have multi rules with inside cams and that makes it alot easier as no trees, cars, light, etc causing problems

But what you described would be three separate triggers running on three separate cameras.

I'm talking about three separate (but different) triggers all running on the SAME camera.

The software allows this, but I'm pretty sure that the hardware doesn't.

After some testing, it seems a bit random as to which of the 2, 3 or more sensitivity settings the camera will use.

The whole "4 cameras needs 16 rules" thing is a real weakness, and random data clashes like this make it een weaker.

Shame.

PaulOckenden,

Correct me if I am wrong but the question boils down to the following.

If cam A detects motion, record on cam A - Motion detection sensitivity at 100%

If cam A detects motion, record on cam B - Motion detection sensitivity at 70%

If cam A detects motion, record on cam C - Motion detection sensitivity at 30%

Which sensitivity dictates if camera A triggers motion detection?

I have escalated this inquiry for further clarification. Please let me know if I have misunderstood the question or any additional details need to be added.

That's exactly right James. The camera is sitting there looking for motion. It'll have a detection level set. But what determines which of these three it is?

Did you ever get a response to this James?

PaulOckenden,

It has been escalated to our engineers and is currently being investigated. For the time being, it is advised that all rules containing a trigger for a specific camera (let's use camera A) use the same sensitivity settings for that camera.

For example:

If cam A detects motion, record on cam A

If cam A detects motion, record on cam B

If cam A detects motion, record on cam C

When using the above rules, keep the sensitivity settings consistent (all 100%, all 70% etc) to ensure that the correct sensitivity is being used.

So, going back to your original question, the camera's PIR is not designed to simultaneously use multiple sensitivities as you suspected.

If I am given any additional information on this topic, I will be sure to post an update.

I hope this helps,

JamesC
