Physical Security Design in Ghana

Good design assumes any single measure can fail, so protection is built in concentric layers. At the perimeter: walls, fencing, gates, vehicle control and lighting. On the approach: standoff, landscaping and natural surveillance following CPTED (Crime Prevention Through Environmental Design) principles. At the building shell: doors, glazing, locks and access-controlled entry points. Inside: zoned access control, CCTV coverage without blind spots, intrusion detection, and hardened areas for cash, servers or other critical assets. Each layer buys detection time and delay, and the design specifies how guards and responders use that time.

A vendor designs around what they sell. An independent consultancy designs around your risk, then writes a specification the market competes to supply. S.G. Technologies' designs are produced by board-certified PSP (Physical Security Professional) consultants and are deliberately vendor-neutral — you receive drawings, performance specifications and bills of quantities that can be tendered, compared and audited. The firm can also install and commission, but the design stands on its own.

Since 2008 the firm has designed and implemented integrated security across the estates of banks and insurers — including centralised monitoring of 800 cameras across 23 Standard Chartered branches — as well as shopping malls in Accra and Kumasi, health facilities, industrial and utility sites, and executive residences. Designs integrate security with fire detection and EVACS so life safety and security work together rather than against each other.

Deliverables are scaled to the project: concept design (layouts, layer strategy, technology choices), detailed design (device schedules, coverage plans, cable routes, integration architecture), tender documentation (specifications and BOQs), and construction-stage support — reviewing contractor submissions and witnessing testing and commissioning.
