Introduction: Why Audio Matters in Security Cameras
A picture is worth a thousand words – but sometimes you need the words too. Two-way audio in security cameras lets you speak through the camera: instruct the delivery driver, call the kids, warn an intruder, or just talk to your pet.
Audio in security cameras has two main functions: Communication (speaking with people in front of the camera) and Deterrence (sirens or voice warnings). We tested the best wireless cameras with audio features.
