Free calculators and planning tools for CCTV and low-current systems

Work out recording storage, how many cameras an area needs and which systems your building needs, before you ask for a quote. Results are preliminary and are confirmed in a site survey.

CCTV storage calculator and how many cameras an area needs

We offer free tools to plan before you ask for a quote: a CCTV recording storage calculator, a tool that estimates the number of cameras and their coverage for the area of your building, and an advisor that picks the low-current systems your facility needs.

Common questions

How do I calculate the hard disk size for CCTV cameras?

Multiply the average bitrate per camera by the number of cameras, by the seconds in a day, then by the retention days. The calculator does this and adds a margin; measure the real bitrate on site rather than the datasheet maximum.

How many cameras do I need for an area?

There is no fixed figure per square metre: the count depends on the task (face or plate recognition, or general view), the lens, the light and obstructions. The design tool estimates the number and shows coverage; the final figure is confirmed after a site survey.
