iCam Source crashing iMac
« on: December 19, 2013, 07:49:29 AM »
When I am running iCam Source on my MAC,  OS X 10.9.1  it appears to be the cause of crashes and automatic restarts.   The error log message that shows is this:

How many cameras are you running and what are the Brand/Models of each? Also, what is the % CPU usage in the activity monitor when the iCamSource is running?

I'm running 2 cameras.   A foscam F9821W with latest firmware, and a Chinese copy of a foscam 8905.   I should say everything worked fine for months,  it may have started around the time of updating to Mavericks,  can't be sure though.

The CPU averages 20% when iCam source is running.

Just a side note,  I use two user accounts on my Mac.  When the other user account is logged in (the one without iCam source installed) it seems to have the problem with the computer restarting.

What is the fps setting for each camera? Please drop it down to about 2-5 fps to see if that improves stability.

You can adjust the frame rate of a Foscam camera by adding a parameter to the URL.


<PARAM> can be a value between 0 and 23, and each value corresponds to:

1:20 fps
3:15 fps
6:10 fps
11:5 fps
12:4 fps
13:3 fps
14:2 fps
15:1 fps
17:1 fp/2s
19:1 fp/3s
21:1 fp/4s
23:1 fp/5s

So to connect to the camera at 2 fps, you would use http://x.x.x.x/video.cgi?rate=14 or to connect at 5 fps, you would use http://x.x.x.x/video.cgi?rate=11
