The Sony microphone (SCA-M30 $348 list) & powered speaker (SCA-S30 $548 list) are not cost effective solutions for use on a Sony camera.
I was wondering if anyone could suggest an alternative. This is the camera (SNCVM601B):
I talked to Sony, they have no other ideas.
(Disclaimer: I am the VMS provider but customer is looking to me for a solution in order to use our intercom feature)
Thank you in advance.
