    2 Way Audio Question

    ITguy posted a topic in System Design

    Hello Everyone I've never worked with audio in a surveillance system before. I have a friend that wants to have 2 way audio. I'm looking at putting in a DVR and 8 CCTV cameras for him. Questions I have... Do any cameras come with built in speakers or is an external speaker always required? Are all audio connections standard or will only DVR cards work with certain cameras that support 2 way audio? Thanks in advance!
