Analysis of The Worldwide Security/Surveillance Camera and the Total amount
We can divide security/surveillance into two viewpoints.
The first viewpoint is sensor type and the second is transmission way.
Sensor type means ccd and CMOS sensor.
Transmission way means Analog and Ethernet output.
From AS magazine Taiwan type, the Total amount of ccd unit are about 24.9 million. But I DO NOT have any quantity information about CMOS of analog output. Regarding CCD IP cam part, it is about 3.%%~5% percent of analog CCD IP cam.
Analysis of diagram.
D.CCD IP camera
E. Nessy Ⅱ solution
SONY Progressive CMYG ccd solution.
You can reference another topic.
F. Retail CMOS IP Camera
This is the most popular CCTV camera in the world. The focus point is image quality and traditional analog composite output.
Analog auto focus zoom camera is about 24.9million x 5%=12.45million
Zoom camera maker need powerful technical including AF solution. The popular maker is including Japan SONY, Hitachi, SANYO, Korea CNB and LG.
Many makers in China Shenzhen claim they have auto focus solution. But compare with Japan and Korea maker, the quality is NOT good enough.
It is very pity that Taiwan’s multimedia ic design house DO NOT understand the big profit about Security auto focus SOC chip.
If you are interested in auto focus solution, you can reference my another topic in my blog.
CMOS sensor maker had provided one chip solution that analog output. But it is similar a little camera maker do not accept quickly. I think CCTV field is NOT consumer market and system integration company do not easily accept new one compared with ccd.
D.ccd ip camera.
It is very interested that IP cam maker do not product ccd camera.
1. If IP cam maker want product CCD IP cam, he will purchase ccd camera from traditional CCTV maker. And then add the compression module. It become CCD IP CAM.
2. If CCTV maker want to product CCD IP cam, he will purchase compression module from IP cam maker. For example, many Shenzhen CCTV maker claim they have CCD IP cam. The most of them use compression mouduel solution.
But the most CCTV maker in Taiwan have started design in SOC compression chip and own IP CAM develop team. The difference between CCTV maker and ip cam maker is not clear.
E.CMOS IP CAM
This type application is for consumer product. Maybe you can buy from Wal-Mart. It is defined as home surveillance and the cost sensitivity is very high.
You can use mobile phone to catch video/picture through 3GPP. it is not concern with security directly.
