Three Related Services

Wiring, Protection and Backup Power

Electrical Wiring

Single-phase and three-phase electrical installation, DB box work and general wiring for homes and businesses.

Lightning Protection & Earthing

Larger-scale earthing and lightning protection systems (MSB earthing) for commercial and industrial buildings.

UPS Backup Power

Uninterruptible power supply installation to keep CCTV recorders, servers and key systems running through outages.

Electrical Wiring

Everyday Wiring, Done to Standard

General electrical installation covers wiring, DB box installation and repairs for both single-phase (typical for homes and small shops) and three-phase (typical for larger commercial and industrial premises) supplies. This is the foundation everything else — lighting, aircon, security systems — depends on.

Common Requests

  • New wiring for renovations or extensions
  • DB box upgrades or repairs
  • LED lighting replacement and maintenance
Lightning Protection

A Bigger-Scale Engineering Service

Lightning protection and earthing (including MSB earthing) is a different tier of work from routine wiring — it's aimed at larger commercial and industrial buildings that need proper earthing systems and lightning protection engineered and installed to protect equipment and structures. This is priced and scoped as its own engineering project, not a small add-on.

Who Needs This

  • Commercial and industrial buildings
  • Buildings with sensitive electronic equipment to protect
  • Properties needing proper earthing system certification
UPS Backup Power

Keep Recording Through an Outage

An Uninterruptible Power Supply (UPS) keeps critical equipment running through a power outage — most commonly for us, that means CCTV recorders and network equipment, so recording doesn't simply stop the moment the power does. We size the UPS to your specific equipment load rather than guessing.

Common UPS Use Cases

  • CCTV recorder and camera backup power
  • Server and network equipment protection
  • Door access controllers, where continuous operation matters

UPS and power product reference

For UPS, backup-power and related power-protection product families, see the separate power / UPS catalogue. HJ Security keeps the scope limited to the power protection needed for ELV, server and network reliability.

FAQ

Electrical, Lightning Protection & UPS Questions

Is lightning protection the same as basic electrical wiring?
No — lightning protection and earthing is a larger-scale engineering service, typically for bigger commercial or industrial buildings, distinct from routine electrical wiring for a home or shop. It's a different price tier and scope of work.
Do I need a UPS for my CCTV system?
A UPS keeps your CCTV recorder and key cameras running through short power outages, which matters if continuous recording is important to you. It's optional but commonly added for commercial systems or anyone who wants recording to continue uninterrupted.
Can you handle single-phase and three-phase electrical work?
Yes, we handle both single-phase (typical for homes and small shops) and three-phase (typical for larger commercial and industrial premises) electrical installation work.
How long does a UPS last during a power outage?
This depends entirely on the UPS capacity relative to your connected equipment's power draw. We size the UPS to your specific load during the assessment so you know realistically how long it will bridge an outage.
