IT Support, Network Installation and CCTV for Nigerian Operations

Why ICT infrastructure needs a power strategy in Nigeria

Most ICT installations in Nigeria treat power as an afterthought. EuroVista treats it as a design constraint from day one — because the grid makes it unavoidable.

Network switches, servers, NVRs, and UPS systems are sensitive to voltage fluctuations. NEPA supply in Nigeria regularly produces voltage spikes of 250–270V and drops to 160–180V. Equipment that is not properly protected will fail prematurely or be damaged outright. Proper installation includes power conditioning — surge protection, automatic voltage regulators (AVRs), and correctly specified UPS units — as a baseline.

A standard UPS extends runtime by 15–30 minutes — enough for a controlled shutdown, but not enough to survive a typical Lagos outage. A solar-backed UPS or a dedicated inverter circuit extends runtime to 8–12 hours, covering the gap between grid loss and generator startup, and supporting sites where generator fuel supply is unreliable.

EuroVista can design ICT infrastructure with a dedicated solar-backed power rail for network-critical equipment. This keeps Wi-Fi access points, core switches, servers, CCTV NVRs, and access control hardware online even when the main generator is off or being serviced. The power rail is sized and documented as part of the ICT design package.

For CCTV systems in particular: cameras require 24/7 power to maintain continuous recording. A gap in power is a gap in footage. We size a separate solar and battery circuit for security systems — independent of the general building load — so recording is never interrupted by power failures.

Network and connectivity installation approach

EuroVista follows a four-stage methodology for every network installation — survey, design, install, and handover — with documentation produced at each stage.

CCTV installation — what good looks like in Nigeria

Many CCTV installations in Nigeria are driven by budget rather than coverage planning. The result is blind spots, storage that runs out in under two weeks, and cameras with no remote access or power continuity. EuroVista's standard addresses each of these failures directly.

Coverage gaps. We map blind spots before specifying camera positions. Placement decisions are based on a coverage plan, not on where conduit happens to be routed.

Storage sizing. NVR hard-drive storage is sized for a minimum of 30 days of continuous recording. Banks, healthcare facilities, and educational institutions should plan for 90 days. H.265 compression is configured as standard — it reduces storage consumption by approximately 50% compared to H.264 at equivalent image quality, which directly affects how far your storage budget stretches.

Power continuity. CCTV systems run 24/7. A solar-backed UPS or a dedicated inverter circuit prevents recording gaps during NEPA outages. The NVR and its associated switches are on a separate protected circuit from the general building load.

Remote access. Cameras are configured for secure remote viewing via mobile app. No open ports are exposed to the internet — access uses VPN or P2P tunnelling, reducing the attack surface for unauthorised access to your footage.

Camera selection. Indoor corridors and retail areas use dome cameras for wide-angle, vandal-resistant coverage. External perimeters, car parks, and entry points use varifocal bullet or PTZ cameras, which allow adjustment of focal length and, in the PTZ case, remote pan and tilt.

Installation standards. External cable runs use conduit and trunking to protect against weather, rodents, and physical interference. Cameras are mounted at 2.5–3m height — the optimal range for facial capture at entry points without distortion from extreme angles.

Microsoft 365 and Google Workspace deployment

Cloud productivity platforms are a starting point, not a finished deployment. The configuration layer — security, identity, and device management — determines whether the platform is safe and usable in practice.

Tenant setup. Domain verification, MX record configuration, SPF, DKIM, and DMARC records are configured to prevent email spoofing and ensure deliverability. Email routing is tested before cutover.

User provisioning. Accounts are created and licensed according to role. Shared mailboxes, distribution lists, and resource calendars are configured as required. Naming conventions and access groups are documented.

Security baseline. Multi-factor authentication (MFA) is enforced on all accounts — not optional. Conditional access policies are configured to address the realities of Nigerian deployments, including legitimate external access requirements from mobile devices.

Device management. Microsoft Intune or Google endpoint management is configured for company-owned devices. For organisations with BYOD, we produce a BYOD policy document and configure minimum compliance requirements before a personal device can access corporate resources.

Migration. PST, MBOX, and POP3 email migrations are handled with a zero-downtime cutover approach. Mail flow is tested in parallel before the DNS switch, and a rollback plan is documented.

Post-deployment support. A support SLA is defined at handover with documented response times for P1 (total outage), P2 (partial loss of service affecting multiple users), and P3 (individual user issues). Support is available via phone, WhatsApp, and remote desktop.
