Good afternoon all,

I am new here, so please excuse my inexperience...

I am looking to add CCTV external outdoor microphones (Netview External microphone) to all 10 of my IP Camera's (Bosch FLEXDOME 5000 outdoor HD). The IP camera's are some distance away from the PoE Switch and NAS storage (furthest is 75 metres).

I need to power these external microphones via 12V DC and connect them to the IP Camera's audio-in - I have attached a diagram of the current setup.

  • My first question is there a Multi output amp that would power all 12v microphones from one power supply? Something that works in a similar way to my 12-channel PoE, but for 12v audio devices
  • My second question would be what type/gauge of cable would be appropriate at the required distances (furthest is 75 metres)?

I appreciate the help that anyone can provide on here. I have been to various Electricians / Security specialist without success

All the best guys and enjoy your weekend

Regards,
Rick
