In the surveillance camera, there are several kinds of Sony CCD, which seems to have different prices! What is the difference? What do you mean by detailed parameters?

Complete configuration of camera DSP chip and CCD

3 142+405 420TVL is economical and applicable.

3 142+633 420TVL CCD just came out. There are fewer manufacturers, and the illumination is very low, but the color cast is serious (I have seen it).

2 163+405 480TVL (so-called false high line)? High cost performance, low illumination, suitable for installing infrared cameras.

2 163+409? 480TVL？ High illumination is not suitable for infrared cameras, but for common gun hemispheres?

4 103+405? 480TVL (so-called false high line)? High cost performance, low illumination, suitable for installing infrared cameras.

4 103+409? 480TVL (the legendary 520TVL) is not suitable for infrared cameras because of its high illumination, and the effect is average.

The illumination of 4 103+639 480TVL (the legendary 540TVL) is ok, which is suitable for installing infrared cameras.

3 172+639 480TVL (the legendary 540TVL) tried many products, but the results were not good.

2 163+255 420TVL low line and low photo, so I won't comment if I use it less.

2 163+529? 480TVL high line and low photo, use less and don't comment.

Should someone else do 4 103+255? 4 103+259? I haven't used it. I don't know how it works

633 will replace 405 in the future, and its sensitivity is much higher than 405. If the technology is in place, the illumination will be very low and the infrared effect will be good.

639 will replace 409 in the future. Sensitivity is much higher than 409. If the technology is in place, it will make up for the poor effect of high-speed infrared cameras in the market.

4 103 is a DSP instead of 2 163, but I don't know why, Sony later introduced 3 172, and the effect of 3 172 is not ideal.

The above are personal opinions, and experts are welcome to fill in and correct them.
