    A customer contacted us with the following questions related to audio surveillance:

    I am in a situation where we need to have the house wired for sound – a living room/kitchen/dining room combo open area and two bathrooms and two bedrooms – the bathrooms could be omitted. The need is strictly for audio surveillance. Could you please give me a guesstimate as to cost? Is it something that your people could come and install relatively inexpensively? I have very limited funds, but this is becoming a high priority to get done and I am not a tech person.

    We answered these questions as follows:

    Although CCTV Camera Pros' specialty is video surveillance, we are also suppliers of surveillance microphones. You can find the one that may be a good fit for the situation that you described here: stand alone audio surveillance microphone.

    The simplest solution that we have to offer is to use these microphones with an inexpensive DVR card that supports the number of channels of audio that you require. Our DVR cards can be found here:

    The cabling that you would use for this can be found here:

    All that being said, I am not sure if a surveillance system is the best fit for what you are trying to accomplish. You may be better off with a home intercom system that has a feature to let you activate or leave certain rooms on (the ones that you want to hear) or be able to select the room from the remote speaker location.

    I would actually recommend looking into that first, especially for a residential install. If what you are seeking is more hidden/covert, then you should consider our audio surveillance equipment.

    Please post any follow up questions to this forum post.

    Thank You.



    I just need audio and I need it hidden so that we can record what happens when we are out of the house.

    Again, CCTV Camera Pros way more specializes in video surveillance and offers audio as an add-on so any system we have is more centered around video surveillance. That being said, the simplest and most affordable solution that we have to offer is the following:

    1. One NUUO DVR PCI card with 4 channel video / 4 channel audio
    2. This stand alone audio surveillance microphone
    3. You can either choose a premade audio/ video surveillance cables that runs both the audio and video to use with the mic or you can use a spool of RG59 siamese cable with BNC and RCA ends that you put on your self like these:

    As much as I do not like to turn down business, we are honest here and recommend that if you are implementing an audio surveillance only solution that you may want to see if there are better audio only solution available on the market.

    Please let us know if you have any further questions.

    My understanding is the Audio Stream Input/Output (ASIO) is used as an interface between a computer sounds card and software application. Typically, with video surveillance applications, the audio is captured by either a DVR card (if you are using a CCTV system) or over TCP/IP in the case of an IP camera that supports audio, not the sound card of the PC itself.

    I am sure there are other ways to do it, but this is the way we are most familiar with.

    Sorry I was not much help.
