System design

What system design covers

Depending on the system and the site, design work may address:

• Requirement definition

  What the system must achieve, in plain terms, before equipment is chosen.

• Equipment types

  Which device types suit the environment, distances and lighting on site.

• Equipment quantities

  How many devices are actually needed for the coverage you want.

• Coverage and layout

  Where devices go so that the important areas are genuinely covered.

• Cabling design

  Cable types, routes, distances and where containment is needed.

• Network design

  Switching, PoE provision and how the system connects for remote access.

• Power and backup

  Supply points, power distribution and standby batteries where continuity matters.

• Integration

  How separate systems are made to work together where that is supported.

• Expansion planning

  Leaving spare capacity so devices can be added later.

• Existing equipment

  What can be reused, and what would hold the new system back.

Design output is a practical equipment and layout proposal. We do not issue engineering drawings, load calculations or certified specifications.

Systems we design

Design covers single systems or several disciplines planned together.

• CCTV surveillance

  Camera mix, positions, recording and storage sizing, and remote access.

• Access control

  Controlled doors, reader types, locking hardware and controller layout.

• Electric fencing

  Perimeter zoning, energiser sizing and alarm interfacing.

• Intruder alarms

  Detection coverage, zoning, panel type and notification method.

• Fire detection

  Detection areas, zone layout, panel position and sounder coverage.

• Intercom systems

  Entry points, monitor positions and gate release arrangement.

• Networking

  Cabling topology, switch placement, PoE provision and headroom.

• Fibre optics

  Where fibre replaces copper, and conversion points at each end.

When system design helps

• You know the outcome you want but not the equipment that delivers it.
• Several buildings, floors or gates have to be covered by one system.
• Quotations you have received differ so much that they cannot be compared.
• The system needs to grow in phases as budget allows.
• New equipment must work alongside equipment you already own.
• Cabling distances or power availability look like they will be a problem.
• A previous system was bought first and planned afterwards, and it shows.
• Coverage gaps keep appearing after each addition to the system.

How design work runs

1. 01

   Understand the requirement

   The premises, the risk and the outcome you need from the system.

2. 02

   Review the site

   Photographs, drawings or a site survey where the site warrants one.

3. 03

   Assess existing equipment

   What is installed, whether it works and whether it can be retained.

4. 04

   Select equipment types

   Device types matched to distances, lighting, door types and environment.

5. 05

   Plan positions and coverage

   Where devices go so the priority areas are actually covered.

6. 06

   Plan cabling, network and power

   Routes, switching, PoE and backup power where required.

7. 07

   Allow for expansion

   Spare capacity so later additions do not force a rebuild.

8. 08

   Present the proposal

   An equipment list and layout you can review, question and adjust.

Designs are revised with you — the first proposal is a starting point, not a final answer.

What to tell us when you enquire

None of this is mandatory, but the more of it you can share, the fewer questions we need to come back with.

• Site location

  The area or town where the system will be installed.

• Type of premises

  Home, shop, office, warehouse, school, apartment block or similar.

• What matters most

  The areas, entrances or assets you most want covered.

• Building information

  Number of floors, gates, doors or the approximate perimeter length.

• Existing equipment

  Anything already installed, including recorder or panel details if known.

• Network and internet

  Whether there is a network on site, and whether remote viewing is wanted.

• Budget range

  A range is enough — it changes which equipment mix is sensible.

• Phasing

  Whether the system must be delivered in stages.
