Doorbell motion detection and dynamic analysis

[nathanb]

Hi,

I have a HikVision doorbell connected to my NVR that is recording. Recently I enabled motion detection on the doorbell but it fires too many false positives. Insects and rain as examples. This is even with sensitivity set to 40!

I have turned it down to 20 to see what it captures on this low setting.

I noticed there is an option for "dynamic analysis" which I believe draws green rectangles around what is triggered. This might be useful to help me adjust regions, but where is the dynamic analysis reviewed? It doesn't show up in HikConnect events, nor on video playback on the NVR, or even event search.

Anyone know?

The Hik doorbell is always going to give false alerts for motion as it doesn’t have AcuSense filtering. It’ll be near impossible to filter out false alerts as any movement will cause triggers (I’d probably set sensitivity to 20 or zero). I had the KV6113 but did away with it. I notice that the 6114 has now been released with 4MP sensor - I’m not sure whether they’ve added AcuSense to it or not.

In the Hik-Connect app Me > Settings > Highlight moving objects should allow you to see motion in the live stream (not sure whether it’ll apply to events also)

Helpful as always JB. Thanks.

"Highlight moving objects" didn't actually enable anything in my setup. Enabling "display vca rule" shows defined region zones and green boxes for moving objects. This ofcourse only works for G series cameras, not the doorbell.

As you said, It doesn't seem to help with events or video playback, which is where I'd want moving objects highlighted to help remove noise.

To your earlier point, it's perhaps moot as I'll never be able to dial in the doorbell (KV6113) to be good at motion detection. I think I'll try 20 sensitivity and if that doesn't help, I'll add arming schedule (it's night time when the ir image triggers many false alerts), or disable motion on this camera completely.

Let's see if 6114 is a decent doorbell. Hik is lacking on doorbells events compared to the leaders.

Part of the issue with basic motion detection in the outdoor stations is that they’ve an extremely wide angle view and you’ve not much control of where it’s covering (as you need to ensure the visitor is fully in view).
