Want to buy one of the latest models. How do I find out?

I have been searching for some time and like Hikvision DS-2CD2686G2-IZS, but it's hard to find in stock.


DS-2CD2T46G2
DS-2CD2T4762
DS-2CD2T86G2
DS-2CD2T8762

I think highest number is better, but what about DS-2CD2686G2 vs DS-2CD2T86G2?

Anyone knew about these?

Bought DS-2CD3B86G2T-IZHSY. Not so cheap, but if it last 6 years as my old camera, it's OK.
