Can you tell me what the difference between sensitivity and threshold is on motion events on an NVR. I assume that the higher the sensitivity number is the more sensitive the motion detection would be however, what exactly is threshold used for?

Camera’s = IPOB-EL3MPIR50
NVR = NVR-ELCE-16-POE16-DH

Second question: Is there a better way to do motion then just relying on pixel changes within the camera? It seems that using pixel changes is subject to a lot of false positives. 

Thanks in advance.

Hi sir,

Sensitivity is how much motion it takes to trigger recording.
Threshold is how long motion has to occur to trigger recording.

The industry standard for motion based recording is currently an algorithm based off pixel changes, unfortunately there are no better alternatives at the moment.

Do I have this right.

Sensitivity 

(less motion to activate) 1——————–100 (more motion to activate)

 

threshold

(less time of motion to activate) 1—————100 (more time of motion to activate)

 

I have been twiddling these two settings. 

Should only be one. They can contradict each other.

IMHO

Correct, 

(less motion to activate) 1——————–100 (more motion to activate)

 

threshold

(less time of motion to activate) 1—————100 (more time of motion to activate) this is basically a tiger. If is set to 1 it will detect motion faster
