An opportunistic attack is characterized by the attacker not being acquainted with the target. These attacks are typically random and take advantage of any available vulnerability rather than being specifically targeted at a particular system or organization. The attacker usually seeks easy targets with known vulnerabilities and acts quickly when an opportunity arises. Axis security documentation describes opportunistic attacks as generally unsophisticated, focusing on exploiting common and readily available weaknesses in systems.

The corridor format is particularly useful for scenes such as the one depicted because it optimizes the camera's field of view for narrow, vertical areas. Traditional horizontal formats waste much of the frame on walls or empty spaces when monitoring hallways, staircases, or aisles. By rotating the camera 90 degrees and using the corridor format, you maximize the vertical field of view, allowing for better coverage and more effective surveillance in such environments. Axis Communications documents and product guides frequently highlight this advantage for corridor format applications.

The main benefit of using Power over Ethernet (PoE) is cost reduction in installation. PoE allows network cables to carry both data and power, eliminating the need for separate power lines and reducing the amount of cabling required. This simplifies installation, reduces material costs, and allows greater flexibility in camera placement. Axis Communications notes that PoE significantly cuts down on installation expenses by streamlining the infrastructure needed for network devices.

The reason why the camera is not blinded by the headlights is that an IR-pass filter is in use. This filter blocks out visible light, including the bright headlights, and allows only infrared light to pass through. This is particularly useful in nighttime surveillance scenarios where the camera can rely on infrared illumination instead of visible light, ensuring clear visibility even in the presence of bright lights like headlights.

The red tip on the cable is used to keep the connectors dust-free prior to installation. It protects the RJ45 connector from dust and debris, ensuring a clean and reliable connection once installed. Maintaining clean connectors is essential for preventing connectivity issues and ensuring optimal network performance. Axis installation guides specify the importance of keeping connectors covered until installation to protect against contamination and ensure a proper connection.

“Modular cameras (also called sensor units) are ideal for discreet and flexible installations in tight or unconventional spaces, such as ATMs, vending machines, and door intercoms, because the sensor and main unit can be separated and mounted independently.”

“Axis modular cameras are specifically designed for integration into machines, kiosks, and other compact environments where space is limited.”

"PoE class 3 delivers up to 15.4 W per port (PSE), with 12.95 W available to the device (PD).

16 × 15.4 W = 246.4 W, but only 16 × 12.95 W = 207.2 W is actually drawn by the devices.

As the total available switch power is 240 W, it can handle 16 PoE class 3 cameras (assuming the draw is calculated at PD consumption)."

— Axis Power over Ethernet Guide

"Class 5 (40 W per camera) and mixed Class 4/Class 5 configurations would exceed the 240 W total switch budget."

Lowering the shutter speed can produce motion blur because the camera sensor is exposed to light for a longer period, capturing the movement of objects within the frame. This results in a blurry representation of moving objects, which can be useful for artistic effects but undesirable for capturing fast-moving subjects clearly.
