Best answer: Thank you for submitting your question about this product. This system utilizes HD-CVI/MPX technology which allows the cameras to output at 4K/8MP while utilizing existing RG59 and higher grade coax/bnc cabling. The Lorex Customer Service Team
Best answer: Please note that the cameras that come with the system do not have a built-in microphone and therefore do not record audio. In order to be able to record audio you will need a camera with a built-in microphone such as the LEV2750 which transmits audio via BNC coax.
