"A lens with a lower f-number (larger aperture) allows more light to reach the image sensor, which is beneficial for low-light performance. For example, an aperture of f/2.0 lets in significantly more light than f/3.6, f/5.6, or f/8.0."

— Axis Communications Academy, Network Video Fundamentals, 2022

"The amount of light entering the camera is inversely related to the f-number. The lower the f-number, the wider the aperture, and thus, more light is gathered by the image sensor."

“Single mode fiber (SMF) is recommended for long-distance connections, typically up to tens of kilometers, as it provides minimal signal loss over long runs. Standard twisted pair (UTP/STP) cabling, such as Cat5e/Cat6, has a maximum recommended distance of 100 meters (328 feet). For distances over 1 km, fiber optics such as SMF are required.”

— Axis Communications Academy, Network Video Fundamentals, 2022

“For connections greater than 500 m, use fiber optic cables. Single mode fiber is suitable for very long distances up to several kilometers.”

"A network with large bandwidth is capable of supporting devices with higher bitrates, allowing for higher resolution, frame rates, or more cameras on the network without causing congestion."

— Axis Communications Academy, Network Video Fundamentals, 2022

"The greater the available bandwidth, the more data (higher bitrate) can be transmitted without causing network issues."

"An IP66 rating means the camera is dust-tight and protected against powerful jets of water from any direction, but not against submersion."

"IP66: Complete protection against dust and strong jets of water."

Firmware upgrades are efficiently installed using AXIS Device Manager. This tool allows for centralized management of Axis devices, enabling easy firmware updates, configuration changes, and maintenance tasks across multiple devices simultaneously. Axis Device Manager streamlines the process, ensuring that devices remain up-to-date with the latest features and security improvements. Detailed instructions for using AXIS Device Manager are available in Axis' support documentation and user manuals.

"Both Computer 1 (192.168.1.10) and Computer 5 (192.168.1.10) have the same IP address assigned within the same network (192.168.1.0/24). This creates an IP address conflict, causing communication errors on the network."

— Axis Communications Academy, Network Video Fundamentals, 2022

"An IP address conflict occurs when two devices share the same IP address, resulting in communication issues for both devices."

"8 Mbps × 3600 s × 24 h × 30 days = 2,592,000 Mb

2,592,000 Mb ÷ 8 = 324,000 MB

324,000 MB ÷ 1024 = 316.41 GB

316.41 GB × 8 cameras = 2,531.28 GB (approx. 2.6 TB for 1 camera for 30 days)."

— Axis Storage Calculator

"8 Mbps continuous for 30 days ≈ 2.6 TB per camera."

The fisheye view from a 360° panoramic camera can be dewarped both on live video streams and stored video material. Dewarping is a process that corrects the distortion inherent in fisheye lenses to present a more natural-looking image. This feature is supported in Axis cameras and video management software, allowing users to view undistorted video in real-time and from recorded footage. Axis documentation confirms that dewarping functionality is available for both live and archived video streams.

“When using fiber connections for network cameras that lack onboard SFP slots, a midspan with an SFP slot is recommended. This device can accept the fiber connection, provide PoE power to the camera, and transmit data over standard Ethernet.”

— Axis Communications, PoE Midspans and Network Accessories

“A PoE midspan with an SFP slot allows you to convert fiber to copper (Ethernet), power the camera via PoE, and handle data transmission all in one device.”

A MAC (Media Access Control) address is a unique physical address assigned to network interfaces for communication on the physical network segment. It is used for direct data exchange within a network, ensuring that data packets are delivered to the correct device. Unlike IP addresses, MAC addresses operate at the data link layer (Layer 2) of the OSI model and are hard-coded into the network interface card (NIC) by the manufacturer.
