How many CCTV cameras does a factory need?

Short answer: A small single-shed factory with one gate usually needs about 10 to 16 cameras; a larger plant with several buildings often needs 24 to 40 or more. Do not start from a number. Count each zone: 2 per gate, 1 every 15 to 20 m of boundary wall, 2 to 4 per production hall, 1 per loading dock, 1 per store entrance and 1 to 2 for the office and cash area, then choose a recorder with spare channels.

Step 1: count the cameras zone by zone

Zone	Typical cameras	What the camera must show
Main gate	2 (one wide, one close)	Faces of people and vehicle number plates coming in and out
Boundary wall and yard	1 every 15 to 20 m of wall	Anyone climbing or loitering, with night vision
Production hall	2 to 4 per hall	Machines, aisles and the hall doors
Loading docks	1 per dock	Goods going in and out of each truck
Raw material and finished goods store	1 per entrance, plus 1 inside large stores	Who enters and what is taken out
Weighbridge (if any)	1 to 2	Vehicle position on the platform and the number plate
Office, cash and reception	1 to 2	Visitors and the cash counter
Parking and canteen	1 each	Vehicles and common areas

Step 2: a worked example

Take a single-shed unit with one gate, a 200 m boundary wall, one hall, two loading docks, one store and an office. The count is 2 (gate) + about 10 (boundary at one camera per 20 m) + 3 (hall) + 2 (docks) + 1 (store) + 1 (office) = 19 cameras. If the boundary wall is covered by fewer cameras with varifocal lenses, or some walls face a neighbour's building, the number drops.

Step 3: choose the recorder and network

• Recorder channels: pick the next size up, for example a 32-channel NVR for 19 to 24 cameras, so you can add cameras later.
• IP cameras and PoE switches carry power and video on one network cable. A single run is limited to about 100 m; beyond that, buildings are linked with optical fiber.
• Recording days: decide how many days you must keep (your policy, insurer or customer audit), then size the hard disks to match.
• Mobile viewing: owners and managers watch live and recorded video on the brand's app, with separate logins.

Common mistakes when counting factory cameras

• One wide camera trying to cover a whole yard: it records movement but not faces or number plates.
• No camera on the loading dock, where most stock disputes start.
• Buying a recorder with exactly as many channels as cameras, leaving no room to grow.
• Long network cable runs past 100 m, which cause cameras to drop out.

Frequently asked questions

How many CCTV cameras does a small factory need?

A small single-shed unit with one gate usually needs about 10 to 16 cameras: 2 at the gate, 4 to 6 on the boundary and yard, 2 to 4 in the hall, 1 per loading dock, 1 at the store and 1 in the office. The exact number comes from counting each zone on site.

How far can one CCTV camera see clearly?

A fixed camera with a wide lens shows useful detail of a person over a short distance, roughly 15 to 20 m. For long boundary walls or wide yards you need more cameras along the wall or cameras with varifocal lenses set to a narrower view.

Should a factory use HD or IP cameras?

Most factories use IP cameras because they give sharper detail, run power and video on one network cable through PoE switches, and can link across buildings over fiber. HD cameras can still suit a small unit with short cable runs.

What size recorder (NVR) should a factory buy?

Choose a recorder with more channels than the cameras you install today, for example a 16-channel NVR for 12 cameras or a 32-channel NVR for 24, so you can add cameras later without replacing it.

How many days of recording should a factory keep?

Set it by your own policy, your insurer or customer audits. More days or higher resolution need more hard disk space, so decide the number of days first and size the hard disks to match.
