But the results were wrong.
If your target is 50ft away, a 2.8mm fixed camera will fail. You need a 6mm or 8mm fixed lens.
Avoid looking strictly at megapixels. A 4K (8MP) camera with a tiny sensor will perform poorly in low light. Look for large progressive scan CMOS sensors that offer crisp imaging.
The focal length is permanently set (e.g., 2.8mm for a wide 100-degree view, or 4mm for a narrower, longer-range view). But the results were wrong
: Focuses on the "fixed" aspect by proposing algorithms (AGG and GGV) to optimize the placement and configuration of cameras with predefined locations to maximize coverage.
While multi-directional and Pan-Tilt-Zoom (PTZ) cameras dominate headlines, fixed network cameras remain the backbone of global surveillance infrastructure. Here is why: 1. Cost-Effectiveness
While its direction is permanent, its internal components provide the foundational security for most commercial enterprises. The Core Components Avoid looking strictly at megapixels
Fixed cameras are significantly cheaper to manufacture and purchase than mechanical PTZ units. You can often deploy three or four high-resolution fixed cameras for the price of a single industrial PTZ.

A fixed 4mm camera mounted 8ft high, angled 15° down, aimed directly at the cash drawer. Varifocal is overkill. Fixed provides repeatable framing. When the POS system sends a "transaction end" signal, the fixed camera records 10 seconds prior via edge storage.
