Answer : C

The maximum distance from a midspan to a camera requiring PoE+ (25.5 W) is 100 meters (328 feet). This distance limitation is due to the standard Ethernet cable length limit, ensuring effective power delivery and data transmission over the network.

Answer : B

Outdoor-ready cameras from Axis can be equipped with a cooling fan and a heater element to handle varying weather conditions. The cooling fan helps manage high temperatures by preventing overheating, while the heater element ensures the camera operates effectively in cold environments by preventing frost and condensation. These features allow the camera to maintain optimal performance and reliability regardless of the weather, as specified in Axis' product datasheets and technical specifications for outdoor models.

Answer : C

An IR cut filter is used to block infrared light during daylight hours to prevent it from interfering with the camera's sensor. This ensures that the colors captured by the camera appear natural. Without an IR cut filter, the infrared light can cause color distortions, resulting in unnatural-looking images. Axis cameras equipped with IR cut filters switch between day and night modes to optimize image quality in various lighting conditions, as explained in their technical documents and user manuals.

Answer : D

The background of the scene is slightly out of focus due to a shallow depth of field. Depth of field refers to the range of distance within a photo that appears acceptably sharp. A shallow depth of field results in a narrow focus area, causing objects outside this area to appear blurred. This can be influenced by the aperture setting of the lens, the focal length, and the distance to the subject. Axis documentation on camera setup and focus adjustments provides guidance on managing depth of field to ensure optimal image clarity.

Answer : D

Fixed box cameras typically use a CS-mount lens, which allows for easy installation and flexibility in changing lenses to meet different surveillance needs.
