Motion Algorithm to Ignore Blowing Leaves/Shadows/Bugs/Snow/Rain/Headlights

Absolutely this. I use CamSource on iOS/MacOS and it allows me to define a grid (e.g. 2x2, 10x10, 25x25, etc.) and toggle on/off any squares I like. That would be a simple way to avoid areas where things are fairly consistent.


I’ll add a scenario for the enhanced motion algorithm. I am getting alerts from the exhaust of my furnace out the back of the house (winter in Chicago). Unfortunately, it drifts around on the image similar to leaves in a random pattern. That said, typically the motion pattern is up-can’t think of too many upward survalence motions that I wouldn’t mind ignoring. :wink:

I call this body detection, which is a dumb version of person detection (which identifies people’s actual faces, etc) and is actually available on some Yi Cameras (I think Yi Camera 2?) I have it and it works. I used to have the Yi camera placed inside my home aimed at my porch, which has some plants in the front and with person detection enabled, the motion detection only triggered when it’s a person that walks into my porch or along the road out by my driveway. Heavy blowing and swaying plants could still trigger it, but it cut down false alerts by about 80%. It’d be a great feature to have.

Voted. The tree shadows alert me too often, even with sensitivity very low.

Also voted -wind, bugs and light&shadow flicker are the major causes of my false alarms. Come to think of it, I guess I should be glad they are false…
This and the time delay would be great!

Here’s a related #roadmap topic you may want to vote for:

Thanks. I already saw it and voted in favor. Bugs and car lights as they turn around at the end of our street are a constant source of aggravation!

I have these mounted outside as well, and I propose a time setting with the motion detection. If the object zips by within 1 second, then ignore, otherwise alert.

There’s a separate #roadmap topic for that. Please visit it and VOTE at the top left of the topic. :slight_smile:


Implement grid based detection zone, so we can mask/filter moving items e.g. trees, scrubs, leaves.



I have the same issue, was looking here for advice!

One solution, now that Wyze Sense is soon to be available for general order, is to use a Sense motion sensor to trigger the camera. It uses passive IR, so less sensitive to small non-warm motions. And bonus, there’s no 5 minute cool down on Sense triggered clips. Only downside is they are not rated for outdoor use.

I say leave well enough alone. Im glad t this $25.00 dollar camera detect EVERYTHING. What I would like, is having the detention time extended to more then 12 seconds.

@Loki what happens when you use it outside? Some people use the wyze cam outside even though you’re not supposed to…

My understanding is that it voids the warranty.
However there are many ways to enclose them to protect them from the elements, ranging from commercial covers to simple things like clear plastic bottles.
The forum has lots of these suggestions.


Yes, a constant issue living in a cul-de-sac at night.

So much wasted alerts and video uploads to their servers for headlights shining on my driveway. A duration setting may prove helpful here in the meantime.

Live on a dead end street with a sign at the beginning that must be written in Sanskrit given the number of people who race down and turn around at the end - right in front of my cams.

As pointed out, they are not warrantied for outdoor use. Unlike the cameras, they won’t work if put behind clear glass or plastic (the IR reflects off those materials). If you were going to do this, you would want to make sure they were very well sheltered from above.

Temperature might be an issue. From the support site:

  • The sensors have been rated for a minimum temperature of 32F. While they can function in lower temperatures, being in those environments may cause battery life to be reduced.

You may be able to find Lithium button batteries to replace the alkalines that ship with the sensors and these may work better in cold temps.

Range might be an issue for an outdoor placed motion sensor. From the Support site:

The PIR Motion Sensor has an effective range of 26 ft, but this will vary based on where you place it, and the orientation of its placement.

Most straightforward way to do this without having to send data to the cloud is to run a basic face detection algorithm on the camera itself - which will help to reduce false alarms. Modern machine learning techniques can compress the models down and have them run efficiently in realtime. May require a small increase in hardware cost, though.

Ignoring leaves and shadows will be great idea with WYZE cam, Will be great feature to have.
