CCTV planning knowledge center
A CCTV system design guide should begin with the evidence the project needs, not a shopping list. Use this library to define coverage, compare camera technologies and turn operational requirements into a coordinated system brief.
For security integrators, consultants, distributors and project owners preparing a CCTV brief or reviewing an early design.
Answer first
Define the evidence required for each scene first; then coordinate camera views, network, recording, storage and power around that requirement.
Translate operational risks into camera views and evidence requirements.
Compare camera form factors, lenses, analytics and environmental ratings.
Review topology, redundancy, cybersecurity and BOM completeness before procurement.
Decision area 01
Start with the project brief, system topology, camera count, BOM, redundancy and design-review controls.
