How do I choose optimal recording settings for a webcam?
Here you can find detailed recommendations how to spread the load between the processor and the bandwidth to attain optimal performance:
- Open Ivideon Server and press «Settings» button (the one with the wrench icon). The button is active only when Ivideon Server is stopped.
Go to «Advanced» settings and then to «Webcams Recording Settings»:
Here we’ll need all the 4 characteristics. For example by reducing video quality or enhancing the network loading, we can reduce processor load:
2.1 Resolution. The higher the resolution, the higher the processor load and the larger the bandwidth required, but the video quality will also be higher. If you select «High» resolution, the video taken from the camera will have max possible resolution.
2.2 Video format – the method of video coding. See the table below to choose the optimal settings:
2.3 Bit rate – the level of data compression, denoting the bandwidth. In other words it’s the max volume of data a certain camera can transmit. The higher the bit rate the higher the processors load. This will also require the larger bandwidth, but the video quality will also be higher.
2.4 Frame rate is the number of shots which a person can see one after another per one second. The higher the bit rate the smoother will be the video, but the processor load and the bandwidth will also be higher. However for every human being frame rate is quite an individual thing, so select it in accordance with your personal requirements.
It stands to reason that the high-quality motion detector loads the processor heavier than the low-quality, but the video quality will also be higher.
Watching videos on iOS devices (iPad, iPhone, iPod) creates additional system load - such devices use special video format into which the video should be coded.
Watching low or medium quality videos in Ivideon Client or Personal Account will also create additional processor load, while it requires additional video conversion.
