Скачать или смотреть ASIS PSP Study Guide: Video Surveillance Systems (VSS), DORI Standard & CCTV Design

Video Description:

Why is security footage often so blurry when our phones shoot in 4K? The answer isn't just about buying better cameras—it's about strategy. In this ASIS PSP (Physical Security Professional) study guide, we pull back the curtain on how professionals design Video Surveillance Systems (VSS) to guarantee usable evidence.

We break down the "DORI" standard to turn clarity into a measurable science, explain why the "PTZ Trap" is a costly mistake for unmanned recording, and cover essential technologies like Wide Dynamic Range (WDR) and H.265 compression.

🚀 In this video, you will learn:

The shift from CCTV to VSS (Video Surveillance Systems).

The 3 functional missions of a camera: Surveillance, Assessment, and Forensics.

The DORI Standard (Detection, Observation, Recognition, Identification) and the magic number of 76 pixels per foot.

The difference between Fixed, Varifocal, and PTZ lenses.

Why PTZ cameras are often a trap for recording purposes.

Technical essentials: WDR (Wide Dynamic Range), H.265 vs. H.264 compression, and calculating storage needs.

A real-world "Spider Web" tip that you won't find in user manuals.
