Basic Of CCTV – Module 3

Overview: CCTV Solution CAD Design

This module moves from basic site planning to the technical engineering required for professional surveillance. The goal is to master Computer-Aided Design (CAD) to create precise, evidence-based security layouts.

By the end of this module, you will be able to:

• Use digital design software (AutoCAD, JVSG) to plan precise building drawings and security networks.+2
• Analyze site floor plans to calculate scale, recognize architectural obstacles, and eliminate blind spots.+2
• Strategically position cameras and NVRs based on environmental conditions and coverage requirements.+1

Here are the key areas we will explore:

• CAD Tools & Methodology: We will look at industry-standard software for creating multi-layer designs that separate cameras, wiring, and network paths.+1
• The Positioning Matrix: We’ll explain the ideal mounting heights and angles for different camera types, such as Dome (8–10 ft) for wide areas and Bullet (10–12 ft) for perimeters.+2
• Infrastructure Engineering: We’ll cover cable routing to avoid electrical interference and how to plan for 20% power overhead to allow for future expansion.
• Advanced Architecture: We will explore Multi-Site VMS Design, focusing on local recording redundancy and automatic failover for high-availability systems.+1
• Environmental Strategy: We’ll look at the “clean room” requirements for NVRs, including temperature control (15–35°C), dedicated PoE switches, and UPS backup.

This module provides the engineering foundation needed to deliver precision CCTV solutions through expert design and field implementation.
