CCTV cameras with audio allow you to record sound as well as video, and in some cases speak to people through the camera using two-way audio. Video tells you what happened - audio tells you why it happened. This is useful in a wide range of situations, from monitoring staff areas and reception desks to communicating with visitors at a gate or deterring intruders verbally.
Our audio camera range includes models with a built-in microphone for audio recording, and models with two-way audio (built-in mic and speaker) for live communication. Two-way audio is particularly popular on outdoor cameras covering front doors, driveways, and access points where you want to be able to speak to visitors remotely via the Hik-Connect app. For IP cameras, audio is carried over the same ethernet cable as the video - no extra wiring required.
Important: recording audio in the UK is legal on your own property, but you should make visitors aware that audio is being recorded. A simple notice near the camera is sufficient in most cases. Our CCTV buyers guide covers the UK legal requirements in more detail.
Audio over Coax (AoC) is supported on compatible HD-TVI cameras and DVRs, allowing audio to be transmitted along with the video signal over standard coax cable - no separate audio cable required.
For two-way audio to work remotely on your phone, you will need a compatible NVR and the Hik-Connect app. Browse IP CCTV systems for matched kits that include audio-capable cameras and a compatible recorder.
