Harp Visual Communications

What Harp Visual Communications does

Harp Visual Communications Limited is a privately held UK audiovisual systems integrator founded in 1998 and headquartered in Fareham, Hampshire. The company designs, installs, and supports AV infrastructure for control rooms, secure briefing suites, operations centres, transport networks, and other mission-critical environments. Its customer base spans defence and security (NATO, UK MOD, RAF, Royal Navy, FCDO, MET Police), transport and infrastructure (Transport for London, Tubelines, Mersey Travel, Strathclyde Partnership for Transport), government (HMRC, National Grid, Thames Water, Runnymede Borough Council), finance and trading, space (Satellite Applications Catapult, ESA), enterprise (BBC, Bloomberg, Reuters, Unilever, O2, Vodafone, BT, BP), and education (Universities of Leeds, Portsmouth, Reading).

The company's core technology is built around three UK-designed and manufactured proprietary products: the MERLIN video wall processor (supporting up to 128 feeds and 64 screen outputs with KVM, encrypted IP streaming, and dual redundant hot-swap PSU for 24/7 operational rooms), the HDMI Data Blocker (a hardware-enforced unidirectional interface device evaluated within UK Government and MOD environments), and CommandaNT touch-panel control software. These are complemented by a broader display and AV portfolio (LCD and LED video walls, Rhino display enclosures, interactive touch panels) and integrated third-party platforms (Crestron, AMX, Extron, Biamp, Shure, Matrox, Datapath, Poly, Logitech, Zoom, Microsoft Teams).

Harp Visual generates revenue through three streams: project-based AV system design and integration, sale of proprietary hardware and software products (both standalone and as part of system deployments), and recurring maintenance and support contracts tailored to system criticality. All sales are project-based and consultative, with pricing quoted on scope and complexity rather than published list pricing. Go-to-market is direct enterprise field sales primarily in the UK, with international delivery capability for defence programmes, supported by UK government and defence procurement framework listings.

Revenue model

1. AV System Integration Projects: Project-based design, delivery, and integration of AV systems for control rooms, secure environments, transport operations, and enterprise spaces. Revenue is generated through one-time project fees scoped to system complexity, equipment specification, installation conditions, and long-term support arrangements. Projects range from single-room installations to large-scale multi-site deployments.
2. Proprietary Hardware Products: Sale of UK-manufactured proprietary products: MERLIN video wall processor, HDMI Data Blocker, and CommandaNT control software. Products are sold as part of system projects or separately to organisations requiring specific hardware components. Additional revenue from spare parts, replacement displays, and accessories through maintenance contracts.
3. Maintenance and Support Contracts: Tailored maintenance and support packages for installed AV systems. Scoped to system criticality and operational requirements, including remote monitoring, proactive maintenance visits, firmware management, fault response, and configuration changes. Support arrangements range from standard response cover to 4-hour physical attendance options in the UK and 24/7 engineer-manned service desk coverage internationally.
