Quantification Analysis for IP cam

There is several type of IP CAM in the market. In this topic, I will be quantification for these factors. For example, PTZ, MPEG-4/MJPEG, CCD/ CMOS and etc.

What kind of factor is more important? What is its relative value

I will depend on Axis IP CAM price to analysis the factor value using static method.

Numerical analysis:

1. I get the Axis IP cam price from Axis’ Taiwan agent.

2. I think these price lists will inform me two information

A. sort/priority of factor

B. The relative weight of factor. But not absolute weight

3. Finally, we can understand which factor is important and realize every factors’ relative weight.

First, I divided Axis IP CAM into 3 types.

Those are Low cost CMOS IP CAM, middle end CCD IP cam and PTZ/speed dome series.



Quantification analysis for IP CAM’s factor

The add value form high to low is as below.

1. PTZ platform :Fixed <>

2. Auto focus: fixed <>

3. resolution : VGA <>

4. D/N switch normal <>

5. Sensor : CMOS <>

6. Compression : MPEG4 <>

We only can realize the factor rank (relative value) but NOT its quantification (absolute value ).





Only if we have enough data base to do the static multi factor analysis

如何正確測試出視訊擷取卡的視訊延遲

 如何正確測試出視訊擷取卡的延遲? 有些廠商採用SWITCH的HDMI輸出連接分配器一路接電視, 一路接筆記電腦....然後, 算出 電視和筆電的差異的秒數  這樣的計算方式會有問題..... 如果測試的電視本身高延遲, 那麼測試出來的秒數差異就會變低, 會有低延遲的假象 就...
