Designing a video surveillance system is a critical phase that determines the effectiveness and reliability of an entire facility’s security. Calculation errors lead to blind spots, budget overruns on unnecessary equipment, or recording failures.
Fortunately, modern free CCTV design software helps avoid these issues by providing professional solutions at zero cost. In this article, we explore how to use JVSG’s free software to create impeccable CCTV projects.
Why Does CCTV Design Require Specialized Software?
Manual calculations often result in errors in:
- Optics: Incorrect focal length → blurry footage.
- Data storage: Miscalculated disk space → lost archives.
- Power supply: Wrong UPS selection → camera downtime during outages.
JVSG’s free tools automate these tasks using international standards (IEC/EN 62676-4).
