Foscam - After the latest updates outdoor sensitivity issues
Hello,
After the latest upgrade I have been having a difficult time trying to set motion sensitivity levels. My wired/wireless foscam cameras are triggering motion sensitivity much more frequently. I am using the mask and setting the sensitivity to 20% and its still happening. Anyone else seeing this?

In general, try a trigger time of 1 or 2 seconds (you can choose this in the Setup section of the Camera Settings window), and make sure that the mask is covering areas that you don't want included in motion detection (areas covered by the green mask are ignored for motion detection).
I am also having the same issues that twarren has said, also using foscams. Before the update I had very few false detections. Since update I have loads. I will wetransfer you a few example files now.
Just wondering if you got my files and if you have any update on this issue?
Thanks
Further, applying a mask to the top 20% or so of the "Back Door" camera cuts out the remaining movie. So I think applying the above settings will greatly reduce your false-positive rate, while still keeping the cameras sensitive to real motion.
The beta will be released as a full version very shortly, but for now there is no downside to using it.
Hope this helps.
Same issues with 3.4.4b8 . Set @ 35% with 1 second delay. Constantly tripping motion.
The main problem we're seeing now is changes in lighting conditions causing false-positive detections. So we have tweaked the algorithm to be more tolerant of this, and combined with a 2-second trigger time this cuts down all instances of this we have seen. Anyone who wants to test can try the latest beta version of SecuritySpy (currently 3.4.5b1).
@twarren - the beta will help, however your example files also show that the cameras are providing very low frame rates, and very uneven streams (e.g. several frames in a row, then a several-second gap). This is contributing to your false-positive detections. You should investigate why this is the case - could be wireless interference, network bandwidth or camera settings. Getting a consistent stream of at least 5fps coming in to SecuritySpy is going to give you much better motion detection, and much more useful captured footage.
I tried your Beta, and it helped a little with fast changing lighting conditions (partly cloudy skies with high winds) However the still images left a bizzare trail of dots streaming behind cars and moving objects... videos look OK.
It also seems to introduce a weird color cast on objects with high specular highlights.
Is it just me?

Sorry about the dots - that's a debug setting in SecuritySpy where it shows you exactly where motion has been detected in the video frame. I've disabled the dots and uploaded a new beta, so if you go to the same link you can download the updated version with this disabled.
The colour cast on high-brightness objects will be down to the camera itself.
