Most security systems in small shops and offices are bought in a hurry, often after a break-in. A few cameras go up, a recorder goes on a shelf, and nobody checks it again until something happens and the footage is missing, blurry or pointed the wrong way.

This guide is for owners and managers of shops, pharmacies, showrooms, small offices and branches in Zanzibar. It covers cameras, alarms, access control, the till, the payment network and remote viewing, and how they fit together.
Power cuts. A recorder without a UPS stops recording at exactly the moment the lights go out, which is also a moment thieves can use. Cameras powered from the recorder or a PoE switch stop too, unless that is on a UPS.
Surges and lightning. Power returning after a cut, and storms, regularly kill recorders and power supplies. Earthing and surge protection, especially on outdoor camera runs, are worth far more than their cost.
Salt air and humidity. Outdoor cameras and junction boxes near the sea corrode. Use outdoor-rated cameras, sealed junction boxes and stainless fixings.
Stone Town heritage rules. Stone Town is a UNESCO World Heritage Site, and visible external changes need approval from the conservation authority. Cameras, alarm sirens and cables on a façade are visible changes. Plan discreet positions and check with the authority before installing.
Thick walls. Coral-stone and concrete walls make cable runs harder and block wireless cameras and alarm sensors. Wired is usually more reliable.
Internet. Fibre is not everywhere, and 4G is a common primary or backup link. Remote viewing depends on your site's upload speed.
Spare parts. Recorders, hard disks and cameras are often stocked in Dar es Salaam. A failed disk can mean days without recording unless you plan for it.
Think in layers: deter, detect, record, and control who gets in.
Choosing the right camera for each spot is covered in Which Camera Type and Bullet vs Dome Cameras.
Note Put up clear signs that CCTV is in use, and decide who can view and export footage. Tanzania has a Personal Data Protection Act; if you are unsure of your obligations, ask a legal adviser.
Cameras record a burglary; an alarm tries to stop it. A basic alarm has motion sensors, door contacts on entrances, a siren, and a panel with a battery backup. Choose one that notifies you by phone (via a SIM or the internet) when it goes off, because a siren alone may not bring help at night.
For offices and back-of-house areas, card, fob, PIN or fingerprint access lets you:
Access control must release doors in an emergency. A qualified installer will connect it so exits stay usable during a fire or power failure.
Card terminals and POS tills should not share a network with guest Wi-Fi, staff phones or CCTV. On a business router, put them on their own VLAN or network so a compromised phone or camera cannot reach payment devices. At minimum:
Watching your shop from your phone is useful, but do not open router ports to the recorder. Use the manufacturer's cloud service with a strong password and multi-factor authentication, or a VPN. Full detail is in How to View Your CCTV on Your Phone Safely.
The RANS Company Limited office is an office project where Extrion delivered LAN, fibre, CCTV, IT systems and business applications, systems integration and technology support. The Kilimo warehouse in Malindi shows security at a larger scale, with LAN, fibre, CCTV, access/security, fire systems and PA.
Warning Mounting cameras on high walls or ceilings means ladders and electrical work. Use a qualified installer with proper access equipment, and never work on mains wiring yourself.

Many small shops start with four: entrance, till, stock room and outside. The right number depends on the layout and blind spots.
Wired cameras are usually more reliable in buildings with thick walls, and PoE lets them run from the UPS. Wireless can suit places where cable is impossible.
Long enough to notice a problem and retrieve footage, often two to four weeks for a shop. Use the storage calculator to size the disk.
CCTV records what happens; an alarm can scare intruders off and alert you immediately. They do different jobs.
Yes. Most recorders and apps support several sites, as long as each is set up for safe remote access.
If you are opening a new shop or office, have had a break-in, or are not sure your system records when it should, Extrion can audit and design the right setup. See our security service or contact us.
This guide is general information to help you plan. Prices, product features and regulations change, so confirm the details for your own site before you buy.
