Difference between Dahua VTO2202F-P-S3 and VTO2201F-P-S2 intercoms

[maxromanovsky]

Is there any difference feature-wise between Dahua VTO2202F-P-S3 and VTO2201F-P-S2 intercoms?

Both of them are not EOL.

From what I could find, VTO2202F-P-S3 supports:

• 2-wire
• newer firmware (and might be more complex to setup without VTH)

Other than that, they seem to be identical.
