There are many times when CCTV cameras with built-in audio (microphones) seem like a great value and a great idea.  If you have looked you probably noticed that we have very few options for those cameras.  While we can get them (send us a request here) we have not had great experiences with them in the past.  If you’re in the market for a camera with built-in audio, here are a couple of things to keep in mind.


Before thinking about the mics, think about the DVR.  The microphones (even ones built-in to cameras) need an input on the DVR.  Buying 8 cameras with 8 mics for an 8 channel DVR that only accepts 4 audio inputs is a frustrating experience.  Make sure to view the specs of the DVR for the audio inputs and don’t forget the speakers.  The DVR will have an audio output but the speakers do not come with it.

Match CCTV Audio Input



For CCTV with audio, placement of the mics is as important as the placement of the cameras.  As an example, consider an indoor room.  If one CCTV camera and one microphone were used to monitor a room the camera should be in the corner to view the majority of the room.  The audio however rarely takes place in the corner.  An omni-directional mic placed in the center of the room is the best bet for quality recording.  Because of these different placement requirements, we recommend separate mics that are not integrated into the camera.

Audio Microphone Placement for CCTV



Whether or not your CCTV system is using built-in audio or separate mics, there are some serious legal considerations you should know.  CCTV with audio recording has different legal implications from state to state.  Before installing audio recording devices check the laws of your state.

For instance, the following US states require consent of ALL parties involved in a given conversation:

  5. Brill site will defo be using live chat and would love to purchase systems from you – great accurate info, very very grateful, soo much choice soo little honest help you are a real inspiration that needs sharing on facebook/utube thank you :)

  6. When it comes to home security, cctv, and stuff, I always read your blog. It never fails to amuse me. Keep it up

  7. With havin so much content and articles do you ever run into any problems of plagorism or
    copyright infringement? My site has a lot of exclusive content I’ve either written myself or outsourced but it appears a lot of it is popping it up all over the internet without my agreement. Do you know any ways to help protect against content from being ripped off? I’d genuinely
    appreciate it.

  8. hi I have 8survilance IR 264 cctv camera system ,I want to get micropone for it I dont know which micropone to buy can you tell me name or the model no for this micropone

  9. Hi Travis, I have big project and the customer need cctv video room, audio room and internet room. In the project two rooms sharing and the third is sprite. Which are the best ways for making these rooms. I think the video and audio to gather and internet sprite. Please give me your idea. Best regard’s

  10. I want to design a virtual training techical training center. I have a limited knowledge of the CCTV do you think this will be the best deal for me? The arrangement of the training room is such that the trainees will be with the hardwares and from a remote location via internet the trainer should be able to display the litratures, have video and audio of the trainees.

    • Mazi,

      If you are looking to buy this mic for use in recording videos for training I would be against it. CCTV equipment is for surveillance purposes but it is not the best choice for recording broadcast quality video and audio. If you are making videos you will want a mic designed for that purpose.


  11. Hi Travis, Your article is interesting, but the doubt that I have is How much distance can it be between the DVR an the Microphones, we are currently using Pelco´s DX4516 DVR´s, and what kind of microphones do you recomend?

    • The brand that we sell the most here is ETS. The SM5 Kit is our best seller. According to the manufacturer the limit for a run is 1500 feet which is more than anyone probably needs.
