A privacy mask in Live View is used to hide parts of the scene from being viewed or recorded, ensuring privacy in specific areas of the surveillance footage. These masks can be configured in various shapes to cover the required sections effectively. Privacy masks are particularly useful in environments where certain areas need to be excluded from monitoring to comply with privacy laws and regulations.

A P-iris lens is a type of DC-iris lens that incorporates feedback to maintain optimal image quality. Unlike a standard DC-iris, which only adjusts based on light levels, a P-iris lens uses a feedback mechanism to optimize the iris position, ensuring consistent image sharpness, depth of field, and optimal contrast. This technology allows for precise control over the iris, which is especially beneficial in varying lighting conditions. According to Axis documentation, P-iris lenses are designed to deliver better performance by continuously adjusting the iris for optimal image quality.

When controlling an analog PTZ camera using the Pelco D protocol, the Device ID (sometimes referred to as the address or camera ID) is crucial for ensuring that the correct commands are sent to the intended camera. If channel 1 is controlling the wrong analog PTZ camera, adjusting the Device ID will correct this without the need to change physical cables. Each PTZ camera must have a unique Device ID to ensure proper control within the system. Axis Network Video documentation details the setup and configuration of PTZ control protocols, including the importance of correctly assigning Device IDs.
