Anyone know why this camera

Is half the cost of this one?

Also, whether both will work with a 7616N E2/8P NVR?

I was thinking of going with the less expensive ones but couldn't figure out why they were so much less expensive!

About double the price... because one is WDR 4MP and the other is 3.6MP and for the Chinese market.

Top one will only work with 7616N if you have the latest firmware (it's also Chinese... so not sure if you'll get region mismatch).

To be honest, I'd rather get the 2CD2332-I which is tried, tested, proven and I know will work than the Chinese only market 2CD3345-I which might cause you all many of grief for near no upside. But because of the image quality especially in low-light, I'd get the 2CD2342FWD-I for the extra if it was me.
