Thank you for your help !:)) |

yes, I tried that software with my previous webcam, which does not |
| 49 |
offer HD or Full HD as the current one. With my setup (means: may be I |
| 50 |
did something wrong...;) it eats too much resources...there is only |
| 51 |
one Linux box for me work and for detecting motions and for recording |
| 52 |
video. |
| 53 |
|
| 54 |
The Logitech offers 1920x1080 Full HD HD264, which needs to be decoded |
| 55 |
frame by frame, analyzed and when found "interesting" to be recorded |
| 56 |
to disc while further analyzing steps are running. |
| 57 |
|
| 58 |
If motion failed (with my setup) to work with """"low res"""" video |
| 59 |
streams I dont think that it will successfully run under the load of |
| 60 |
Full HD. |
| 61 |
|
| 62 |
Furthermore there is a delay of ~1 second between "reality" and video |
| 63 |
possbly due to not that fast compression hardware in the camera... |
