The camera sensors in Axis’ multidirectional cameras can be individually adjusted. This flexibility allows each sensor to be positioned independently, enabling optimal coverage of the desired areas. Such adjustability ensures that a single camera unit can cover multiple directions or areas, enhancing the efficiency and effectiveness of the surveillance setup. Axis' multidirectional camera specifications and manuals provide detailed information on this feature.

Typically, a system designer calculates the pixel density based on the horizontal resolution and the field of view. Pixel density is crucial in determining the level of detail a camera can capture in a specific area. Horizontal resolution refers to the number of pixels along the horizontal axis of the image sensor, while the field of view is the extent of the observable area captured by the camera. This calculation helps in ensuring that the camera setup meets the surveillance requirements.References: Axis Communications Design Tool

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.

If a PoE (Power over Ethernet) switch is unable to supply sufficient power to a network device, a midspan, also known as a PoE injector, should be used. A midspan is an external device that adds power to the Ethernet cable, thus providing the necessary power to the network device. This is particularly useful when existing network infrastructure cannot be upgraded to meet power requirements. According to Axis documentation, midspans are recommended to ensure adequate power delivery for network devices that require PoE.
