Railings and Security Cameras

The railing calculators give the posts, balusters and rails for a deck or stairs, and the baluster spacing for a run. The camera calculators size a system: field of view from sensor and lens, storage for cameras and retention, and bandwidth from camera count and bitrate. The bollard spacing calculator gives the count and equal gaps across an opening. The installation cost estimator adds up cameras, recorder, cable, tax and labor from your own prices.

Tools in this group
