Guides for security and low-voltage design

Practical answers for designers and estimators: PoE budgets, power supplies, cable, camera pixel density and door schedules.

Power

PoE budget explained

Standards, budgets, ports and the 80 % rule.

How to size an access control power supply

Amps, headroom, batteries and voltage drop.

Cable, cameras and doors

How to estimate low-voltage cable

Runs, drops, loops, slack and boxes.

Camera pixel density

Detect, observe, recognise and identify.

The access control door schedule

What every door needs on paper.

How to estimate conduit

Lengths, fill, bends, sleeves and cost.

How to label low-voltage cables

IDs, both ends, plans that match the field.
