CCTV Storage Calculator Excel – Free Download for Engineers

Accurate surveillance storage planning is a critical part of CCTV system design. For MEP engineers, electrical consultants, and security system integrators, incorrect hard disk estimation can result in system failure, insufficient recording days, or unnecessary hardware cost.

To solve this, we provide a professionally designed CCTV Storage Calculator Excel sheet that helps you calculate precise storage requirements based on real engineering parameters.

This Excel-based CCTV storage calculator Excel tool allows you to input:

• Number of cameras

• Bitrate (Mbps per camera)

• Recording hours per day

• Required retention days

• Compression format (H.264 / H.265 / H.264+ / H.265+)

The sheet automatically applies the standard CCTV storage calculation formula:

Storage (GB) = (Bitrate × 3600 × Hours × Days × Cameras) ÷ (8 × 1024)

It also adjusts storage based on compression efficiency, giving engineers accurate GB and TB outputs for technical documentation, BOQ preparation, and client approvals.

This tool is ideal for:

• Commercial building surveillance systems

• Residential CCTV planning

• Industrial security projects

• Data retention compliance calculations

• Technical submittals and tender documentation

By using this CCTV storage calculator Excel, you eliminate guesswork and improve system reliability and cost optimization.

Whether you are designing a 4-camera residential setup or a 32-camera commercial project, this Excel tool simplifies storage estimation and supports professional decision-making.
