Advanced Camera Settings

So I found the advanced commands for the camera would love to have you guy test them out. 

http://iriswebportal.com/cameras.html double click the gears icon.

When you go to the settings page it auto loads defaults. So if you want to set a camera back to the way it was just open the advanced settings page and then click save settings. Also if the camera gets stuck in a motion loop you need to

set motion detection mode to off

save settings 

reboot camera

save defaults 

reboot camera

that should fix it.

 

Let me know what you find or if you find this page helpful.

What is the default IR LED luminance setting for the cameras?  I notice that by default the newer Indoor/Outdoor camera has a much brighter IR LED.

 

Edit:  I am guessing that the default setting is 3.  I experimented a bit and put one of my cameras in a dark room and set the IR Led to 5 and it was brighter.  I have since set them all to 5.  Nice find.  It certainly makes the night image less grainy.

Cool, I notice if I try and change the setting and press save or reboot camera, it goes back to the original setting.I guess you can't change the default?

If you select a drop down box and make a change and click save, it will make the change and all other drop boxes that were left untouched will revert to the defaults.  In other words if you click save without making any changes, defaults will be saved.  The key to using these features is to make all the changes that you want with the drop boxes and click save.

I did make the change and press save. I wanted to see if it save the setting and I double click it again and I guess it defaults to it's setting and not what you saved it as?

What's the difference between motion detection threshold and sensitivity?  I'm trying to cut down on a few false alerts on my outdoor cameras to clean up my history log.

 

Here is a great breakdown of Sensitivity vs Threshold

Quote

There is no clear cut answer to sensitivity/threshold settings that can truly eliminate false positives, while maintaining that they trigger as desired, for all cases. The problem is simply that everyone's cameras will be looking at such drastically different scenes, that one person can have false positives on a very low sensitivity (due to snow) whereas the other can use the same settings and not even catch the movements of trees in the wind.

The best thing you can do is work out a configuration for each camera based specifically on what your cameras are likely to register as motion and customize your settings to your preference. In order to do this, it helps to understand a bit more about how sensitivity and threshold work. 

Think about it this way: sensitivity is a measurement of the amount of change in a camera's field of view that qualifies as potential motion detection, and threshold is how much of that motion needs to occur in order to actually trigger the alarm. It can be thought of like this: for however long there is enough change to satisfy the sensitivity parameter, a threshold meter is silently being filled up until it hit's the trigger point.

Considering this, if you set your sensitivity to 1 and threshold to 100, it would be practically impossible to trigger a motion alert. Alternatively, if you set your sensitivity to 100 and your threshold to 1 or 0, this means that the slightest change could set off the trigger. The trick is to finding a healthy balance based on all the factors that stand to stimulate your motion detection sensors and doing your own personal testing.

A practical application of this would be, for example, a check out line in a grocery store. People don't want every person walking in and out to trigger the alarm. But if, for some reason, one of these people starts dancing or attacking another person, the degree of movement and activity would trip the threshold meter. This feature exists to give users complete control and the ability to both fine tune and customize their motion detection settings.

So in summary sensitivity is what trips the motion sensor and threshold is how long is has to remain active for before sending the event to the hub.  In more detail, a higher sensitivity value requires less image/sensor change to trigger motion activity and a lower sensitivity value requires more image/sensor change to trigger motion activity.  Then once motion activity has been triggered a higher threshold requires the motion activity to remain active for a longer duration, at or above the sensitivity level, to trigger the motion event sent to the hub.  A lower threshold requires motion activity to remain active for a shorter duration to trigger.

I keep meaning to play with this but keep forgetting.  I have a camera that sets on one end of my shop and the other end is a standard garage door, the shop is 22' long.  Opening the garage door and walking about 3 or 4 foot in the shop will not trigger the camera motion sensor.  So I put a second motion sensor on the other end   I am thinking I can now adjust it so that I wouldn't need that second sensor and I can use it somewhere else.

Yeah you might try sensitivity of 8 and threshold of 63.  This would increase the sensitivity of the sensor and decrease the duration of activity required to trigger it if I'm correct.
