This is probably what you're asking for:
Yes, the doorbell , i will first trail selling 10pcs, will collect the bugs, and later make it working as a perfect one. Looney's testing is bit positive.
You mean to connect the VTO to a traditional doorbell? Would that not be possible with one of the alarm outputs on the VTO?The problem with the VTO series is that they are designed to work with a VTH. There is no way to grab a button press on the doorbell other than that or the app. It would be great if they'd make that an ONVIF event but then they wouldn't sell very many VTHs.

Maybe I don't understand you fully, but you mean your problem with the Dahua VTO's is that the actual press of the doorbell button on the VTO does not register like a IVS/tripwire (etc.) event on a normal camera would?
One of each but that 1st one with radar looks expensive.We need to get a sample of the 8MP with the 1/1.2" sensor out for testing. Wild_Cat1 or whoever for the test.
