5MP Smart Full-Colour Dual-Light HDCVI Turret CCTV Camera IP67, Grey - 

Audio signal transmission over coaxial cables is supported by the camera. It employs a unique audio processing and transmission technology that restores the original audio while eliminating noise, ensuring the quality and reliability of the collected audio information. This feature is particularly important for video surveillance applications that utilise audio as a form of supplementary evidence. Smart Dual Light technology employs advanced algorithms to detect targets effectively. Typically, the infrared (IR) illuminator is activated at night. When a target enters the monitoring area, the white light turns on, and the camera captures full-colour video and information about key events. This means that the camera links snapshots and video footage with full-colour images. Once the target leaves the monitoring area, the white light turns off, and the IR illuminator is activated, thereby reducing light pollution efficiently. With its intelligent algorithm, the camera automatically adjusts its parameters to ensure optimal performance and produce vivid images. HDCVI technology supports four signals (video, audio*, data, and power) that are transmitted simultaneously over a coaxial cable. The dual-way data transmission enables the HDCVI camera to interact with the XVR, allowing for various actions such as sending control signals and triggering alarms. Additionally, HDCVI technology supports Power over Coax (PoC), facilitating quick and easy installation of the camera.
