Real-world lighting is rarely perfect. A bright window behind a subject or bright sunlight with deep shadows can ruin footage. Wide Dynamic Range technology uses multiple exposures per frame to produce a balanced image. As the Axis white paper explains, "Backlight, from a window behind an object, can result in overexposure," and WDR is the primary solution for this challenge. Look for cameras advertising 120dB true WDR.
Standard PoE (IEEE 802.3af) allows a single network cable to transmit both high-speed data and electrical power. This eliminates the need to run separate high-voltage electrical wiring to every camera location. Wide Dynamic Range (WDR) Real-world lighting is rarely perfect
Modern fixed network cameras have largely moved past 1080p (2MP). The current standard for reputable brands (Axis, Hikvision, Dahua, Hanwha) is . As the Axis white paper explains, "Backlight, from

Fixed cameras are typically cheaper than PTZ cameras. Furthermore, because they focus on one area, they often allow for a more efficient, targeted system design. 3. Ease of Installation (PoE)
The focal length is permanently set (e.g., 2.8mm for a wide 100-degree view, or 4mm for a narrower, longer-range view).
