    How many security cameras does my business need?

    Count coverage points, not square footage. Every entrance, exit, register or cash point, loading dock, server room and parking approach needs a camera. A small retail store typically needs 4 to 8 cameras, a mid-size office 8 to 16, and a warehouse 16 to 40 depending on dock count and yard coverage.

    Start with the list of things you must be able to prove

    Cameras exist to answer questions after an incident: who entered, who handled cash, who took the pallet, whose vehicle was in the lot. Write the questions first, then place a camera where it answers each one at usable detail. That method produces a defensible count instead of a guess.

    • Every public entrance and employee entrance
    • Point of sale, cash office and safe
    • Loading docks, receiving and stockroom
    • IT and server rooms
    • Parking lot approaches and license plate capture points

    Identification vs overview

    One wide camera covering a whole area gives you context, not identification. Faces need roughly 40+ pixels per foot at the target. That usually means a dedicated, tighter camera at each entrance in addition to your overview cameras — the single most common mistake we correct on existing systems.
