Technology for Hotels and Guesthouses in Zanzibar: A Practical Guide

In Depth

In Depth

A Zanzibar hotel needs guest Wi-Fi that reaches every room, a separate network for staff, payments and CCTV, and power backup that survives the daily cuts. This guide explains how to design that properly, from a six-room guesthouse in Stone Town to a beach resort.

Guests judge a hotel on the bed, the food and, increasingly, the Wi-Fi. A review that says "the Wi-Fi didn't reach our room" costs bookings, and a reception that cannot take card or mobile-money payments during a power cut costs money on the spot. Behind the scenes the same property needs CCTV, a working fire alarm and a back-office network that guests cannot reach.

What makes hotel technology harder in Zanzibar

Power is not steady. When the mains drops, the generator takes a few seconds to start, and every router, switch and recorder without a UPS reboots. Some never come back cleanly, and surges when power returns are a common cause of dead equipment.

Salt air and humidity. Near the sea, unprotected connectors, brackets and enclosures corrode quickly. Outdoor access points, cameras and joints need a suitable outdoor IP rating, sealed connectors and stainless or coated fixings.

Thick walls. Coral-stone and concrete block Wi-Fi far more than the plasterboard consumer routers are designed for. One powerful router at reception will not cover rooms two walls away. Our guide to Wi-Fi dead zones explains why.

Heritage buildings. Stone Town is a UNESCO World Heritage Site. Antennas, external cable runs, cameras on façades and new wall openings are visible changes that need approval from the conservation authority. Plan discreet internal routes and ask before work starts.

Lightning. Outdoor cable runs to a pool bar, gate camera or another building pick up surges in storms. Earthing and surge protection are essential on those runs.

Uneven connectivity. Parts of Unguja town have fibre; many coastal areas rely on fixed wireless or 4G. Almost everywhere, a second connection on a different technology is worth having.

Seasons and spares. The long rains are the quiet time for cabling and upgrades, but installers and parts get busy before high season. Spares often come from Dar es Salaam, so a failed switch with no spare on site can mean days of downtime.

Receipting rules. Zanzibar businesses issue receipts through the Zanzibar Revenue Authority's Virtual Fiscal Management System (VFMS). The VFMS Amendment Regulations, 2026 (Legal Notice 106 of 2026, signed on 5 August 2026) say a business providing accommodation and related hospitality services must use a property management system (PMS) approved by the ZRA Commissioner General. They also require the companies that supply or run that software to integrate it with the ZRA system. Press reports give 2 November 2026 as the compliance date in a ZRA public notice. Before you choose or renew a PMS, ask the supplier for proof of ZRA approval and check the current position with ZRA or your tax adviser. This is not tax advice.

The recommended design: one set of cables, several separate networks

Think of the property as several networks sharing one cable system and one or two internet connections. On a business-grade router or firewall and managed switches, each is a VLAN (virtual network). One cable to an access point can carry the guest and staff networks at the same time, so you do not need a cable per network.

The firewall rules between VLANs matter as much as the VLANs. Guests should reach the internet and nothing else; the POS network should reach its payment service and nothing else.

The physical layer

• A small central rack in a cool, dry, lockable room: router or firewall, core switch, patch panel and CCTV recorder, all on a UPS.
• Managed PoE switches that power access points and cameras over the network cable, so the UPS keeps them running too. Check the power budget with the PoE budget calculator. Our explainer on what a network switch does covers managed and PoE switches.
• Ceiling or wall access points close to where guests use their devices: in or just outside rooms, not only in corridors. In coral-stone buildings, plan on one per room or per small group of rooms. Copper runs stay within 100 metres.
• Fibre between buildings. Fibre covers longer distances than copper, and a non-metallic fibre cable does not conduct surges between buildings. See fibre optic vs Ethernet and, for resorts, network planning for large properties.
• Two internet connections with automatic failover.

Safety and security systems

• CCTV at entrances, reception, the cash point, car park, store rooms and staff entrances. Never in rooms, bathrooms or changing areas. See CCTV cameras explained and viewing CCTV on your phone safely.
• Fire detection suited to the building, from smoke detectors in each room to an addressable panel in a larger hotel: fire alarm systems and conventional vs addressable fire alarms.
• Public address for background music and evacuation messages: public address systems.
• Guest-to-reception communication, such as room phones or call points for villas and accessible rooms.

Extrion has not yet published a hospitality project. The engineering is the same as our hospital work, where we installed LAN, fibre, CCTV, fire, public address and nurse-call systems in occupied 24-hour buildings, such as the Pediatric Hospital at Mnazi Mmoja and the Mental Hospital at Kidongo Chekundu. A hospital ward and a hotel corridor share the same problems: people sleeping, systems that must not go down and safety systems that must work.

Build it in phases

Phase 1: essentials (any size). A business-grade router with separate guest and staff networks; a UPS on the router, main switch and recorder; surge protection; a 4G or second-provider backup with failover; CCTV on entrances, reception and the cash point; working smoke detection in every room.

Phase 2: proper coverage. Structured cabling to every room or room cluster into a labelled patch panel; centrally managed access points with room-level coverage and outdoor-rated units at the pool, restaurant and garden; VLANs for POS, CCTV and building systems; a guest portal (terms or room codes) and per-device limits.

Phase 3: resort scale. A fibre backbone between blocks and villas with distributed switches on UPS; addressable fire alarm and zoned PA; access control on staff areas and stores; monitoring that alerts you when an access point, camera or connection fails, before a guest complains.

Hotel technology checklist

• Walk the property with a phone and note every room or area with weak or no Wi-Fi.
• Confirm guest Wi-Fi is separated from staff, POS and CCTV networks, and test that a guest cannot reach the recorder.
• Turn on client isolation on the guest network.
• Put the router, switches and recorder on a UPS, and test it by switching off the mains.
• Fit surge protection on the incoming supply and on outdoor cable runs.
• Arrange a second internet connection and test failover.
• Check outdoor equipment for corrosion, loose seals and water inside enclosures.
• Confirm CCTV records for as many days as you need, using the CCTV storage calculator.
• Change all default passwords and give staff their own accounts.
• Confirm your PMS is approved by ZRA and connected to VFMS, and that your POS meets current ZRA receipting requirements.
• Test smoke detectors and the fire alarm on a schedule, and log the results.
• Keep spares on site: at least one access point, one PoE switch and patch cables.
• Label every cable at both ends and keep a network diagram.
• In Stone Town, confirm conservation approval before visible external work.
• Schedule upgrades for the low season and book your installer early.

Common mistakes we see

• One big router at reception. Coverage comes from more access points near guests, not more power.
• Consumer equipment in a 24-hour business. Home routers struggle with dozens of guests and often hang after power cuts.
• Guests and the CCTV recorder on one network. Anyone on guest Wi-Fi may find the recorder's login page.
• No UPS on the network. The generator starts, but every device has rebooted.
• Copper cable between buildings. It is the path lightning takes into your rack.
• Indoor equipment outdoors. Indoor access points at the pool bar rarely last a year in salt air.
• No documentation. When the installer leaves, nobody knows which cable goes where or what the passwords are.
• Upgrading in high season. Work is rushed and parts take days to arrive.

Warning Do not open the fire alarm panel, work on mains wiring or climb onto roofs to fix cameras or antennas yourself. Use a qualified electrician or installer with proper access equipment.
